Opening an account, sending funds, setting up a wallet — step by step.
Learn the stepsBeginnerOpening an account at a Japanese exchange generally runs: register an email address, enter your personal details, submit identity documents, wait for review, then start trading. Most operators let you finish identity checks on a phone, and approval typically takes from the same day to a few business days. Before applying, confirm the operator is registered with the FSA as a crypto asset exchange service provider.
6 min
Learn the stepsBeginnerFunding a Japanese exchange with yen normally means either a bank transfer or a 'quick deposit' made through internet banking, which credits immediately. Whichever you use, the critical part is sending exactly to the destination and reference the exchange assigns to your account. Timing and who bears the fee differ by method, so read the operator's own guidance before you send.
5 min
Learn the stepsBeginnerMake your first purchase small enough that losing it would not affect your life, and pick a single asset whose mechanics you actually understand. Simply being aware of whether you are buying from the brokerage or on the order book already changes what it costs you. Work through it in three stages: decide the amount, choose the order type, then check what actually filled.
6 min
Learn the stepsBeginnerAn on-chain transfer, once confirmed, cannot be cancelled or reversed — there is no one to appeal to. Getting either the destination address or the network wrong usually means the funds are gone. That is precisely why you send a small test transfer first, confirm it arrives, and only then send the rest.
6 min
Learn the stepsBeginnerOn a brokerage the operator is your counterparty: it is simple to use, but the gap between its buy and sell quotes — the spread — is your real cost. On an order book you trade against other users, can place limit orders, and generally pay less. The same asset at the same operator costs a different total depending on which screen you use.
5 min
Learn the stepsBeginnerMetaMask is the most widely used self-custody wallet on EVM chains. Your keys live on your own device and the vendor never holds them — which means nobody can recover your funds if you lose the seed phrase, and they are gone the moment someone else has it. Only ever install it from the official site.
6 min
Learn the stepsBeginnerA hardware wallet exists to keep your private key off internet-connected devices. Whether it actually delivers that comes down to how you set it up — above all, buying new from the official store and reading the recovery phrase only from the device's own screen onto paper. Miss either and the device stops being worth having.
6 min
Learn the stepsBeginnerConnecting a wallet to a dApp does not, by itself, move anything. Assets move when you confirm a signature or an approval afterwards. Which is exactly why checking the domain you are connecting to, and actually reading the signing prompt, is the defence.
5 min
Learn the stepsIntermediateA block explorer is a public viewer for everything recorded on a blockchain. It lets you check why a transfer has not arrived, investigate what a token actually is, and see what fees really cost. Learning to use one means you can establish the facts yourself before asking an exchange or a support desk.
6 min
Learn the stepsIntermediateA DEX lets you exchange tokens by connecting a wallet, with no account to open. The flip side is that nothing is vetted — scam tokens sit on the same screen as real ones — and a mistake cannot be undone. Fix a routine for yourself: identify the token by contract address, then check slippage and the fee breakdown, before you swap.
7 min
Learn the stepsIntermediateAnyone can mint a token with any name and symbol, so a name tells you nothing about authenticity. The only identifier that means anything is the contract address: take it from the project's own channels and corroborate it in an explorer. If you cannot confirm it, the right call is to leave it alone.
6 min
Learn the stepsIntermediateUsing DeFi or NFTs leaves behind approvals — standing permission for a contract to move your tokens. They stay valid until you explicitly cancel them, and a contract later exploited becomes a route into your wallet. Review the list periodically and revoke what you no longer use.
6 min
Learn the stepsBeginnerJapanese exchanges must register with the FSA and are built around yen deposits and Japanese-language support. Overseas exchanges list more assets and offer more features, but many are not registered in Japan, leaving the user carrying the risk if something goes wrong and the burden of tax and paperwork. It is not a question of which is better, but of what you are taking on.
6 min
Learn the stepsBeginnerThe cost of using crypto is not just the trading fee on the label. A proper comparison adds up the spread, deposit and withdrawal charges, transfer fees and on-chain gas, applied to how you actually intend to use the service. Rates differ by operator and get revised, so always check the current figures on the official site.
5 min
Learn the stepsBeginnerTwo-factor authentication is the minimum protection that keeps an account safe when a password leaks. For a crypto account, the right order is to set it up before any money goes in. And unless you keep the backup codes shown during setup, losing your phone locks you out of your own account.
5 min
Learn the stepsIntermediateSlippage tolerance is a ceiling: how far from the quoted price you will still accept execution. Set it too tight and the trade reverts, costing gas for nothing; set it too wide and it can fill at a far worse price than you expected. The default is usually right — widen it only when a trade fails, and only by as little as it takes.
6 min
Learn the stepsIntermediateOn a DEX, the larger your trade relative to the money sitting in the pool, the worse the amount you receive. Being able to buy does not mean you will be able to sell the same amount back. Before swapping, make it routine to look at the pool's size, how much genuinely trades, and what your own size does to the price.
6 min
Learn the stepsIntermediateProviding liquidity means depositing your assets into a pool so that other people's trades can execute against them. You share in the trading fees, but the further the two deposited assets diverge in price, the less you end up with than if you had simply held them — impermanent loss. On top of that sits the permanent risk that the contract holding your deposit fails.
7 min
Learn the stepsIntermediateWithdrawing liquidity means returning the token that represents your share and receiving the two assets in whatever ratio the pool currently holds. You do not get back the amounts you put in. Accrued fees or rewards are sometimes tracked separately, so check what sits where before you exit.
6 min
Learn the stepsIntermediateStaking means committing tokens to a network or protocol and taking part in its operation. While committed they are not freely movable, and unwinding can take time. Depending on the design, you take on ways to lose assets that have nothing to do with price: slashing, contract failure, or misconduct by whoever you delegated to.
7 min
Learn the stepsIntermediateUnstaking usually involves an unbonding period between requesting the release and being able to move the tokens, so it is not a route to selling immediately. The price keeps moving throughout, and rewards generally stop accruing. Before you start, confirm the length of the wait, the steps involved, and what happens to unclaimed rewards.
6 min
Learn the stepsIntermediateOn-chain rewards do not necessarily land in your wallet by themselves; in most designs you must execute a claim transaction to take possession. Claiming costs gas, so small amounts can cost more to collect than they are worth. In Japan, receiving a reward can itself be a taxable event, so keep records.
6 min
Learn the stepsIntermediateA bridge takes a deposit on one chain and gives you a corresponding asset on another. In most designs nothing physically moves: the deposit backs a representation issued elsewhere, and if that deposit is compromised, the representation loses what stands behind it. Make a small test transfer before a real one, every time.
7 min
Learn the stepsIntermediateBridges concentrate custodied assets into a single point of failure, and large-scale losses there are a matter of record. No procedure can certify one as safe, but you can improve the judgement: find out who controls the funds, what mechanism guarantees correctness, and whether past incidents are documented openly.
7 min
Learn the stepsIntermediateLending in DeFi means depositing assets into a contract and receiving a share of the interest borrowers pay. Rates float with supply and demand; they are not fixed. If borrowers' collateral collapses faster than it can be liquidated, or if the contract itself fails, the principal you deposited may not come back.
7 min
Learn the stepsAdvancedBorrowing in DeFi means posting collateral and drawing a fraction of its value. You move toward liquidation if the borrowed asset rises in price *or* if the collateral falls. Liquidation takes part or much of the collateral, and it is executed automatically — with no grace period and no notification.
8 min
Learn the stepsIntermediateA health factor expresses how far your collateral-to-debt position sits from the liquidation threshold. It changes continuously with prices, and the moment it crosses the line the position is liquidated automatically. Rather than just watching the number, work out in advance which price takes you into danger, and set up alerts.
6 min
Learn the stepsIntermediateRepaying means acquiring the same asset you borrowed and reducing the debt with it. Repaying in full frees the collateral for withdrawal, but even a partial repayment restores headroom against liquidation. Interest accrues right up to the moment of settlement, so paying exactly the displayed figure can leave a small remainder.
6 min
Learn the stepsAdvancedThere is no method that reliably prevents liquidation. What you can do is keep a large margin on your collateral ratio and react immediately — by repaying or adding collateral — when prices move sharply. Never lose sight of the fact that a thin position can end overnight.
8 min
Learn the stepsBeginnerA testnet is a practice network where you perform the same operations as on mainnet using tokens that have no value. Running an unfamiliar procedure there first, before doing it for real, is the safer way to work. What it does not do is certify that the same action is safe on mainnet.
5 min
Learn the stepsBeginnerTestnet tokens come from a faucet, which distributes them free of charge. They are designed to have no value, so there is never a reason to buy them. If obtaining them requires your seed phrase or any real assets, you are looking at a scam.
4 min
Learn the stepsIntermediateSimulation shows you what a transaction would do to your balances and permissions before you actually broadcast it. Being able to read, in numbers, what leaves and what arrives before signing prevents a large share of unintended approvals and drains. It does not, however, catch every form of malice.
6 min
Learn the stepsIntermediateAn audit is a record that outside specialists examined a particular version of the code — not a certificate that no vulnerability exists. What to check is not the 'audited' badge but who looked, when, over what scope, how the findings were handled, and whether the code has changed since. Audited protocols have still been drained.
6 min
Learn the stepsIntermediateThe figures on a dashboard mean different things, and none of them, taken at face value, says anything about safety or future outcomes. Learn separately what total deposits, utilisation, rates and fee income each describe — and always check what an advertised rate actually includes.
6 min
Learn the stepsIntermediateOnce assets are spread across several chains and protocols, simply knowing what you hold and where becomes hard in itself. Build a routine that lists balances and positions per address and per chain, and that includes the state of your approvals. You cannot protect what you have lost track of.
6 min
Learn the stepsIntermediateExiting a DeFi position is not finished when you sell. It is finished when you have withdrawn from wherever the assets were deposited, repaid any debt, claimed outstanding rewards and revoked the approvals. Since a falling market is exactly when the steps jam up, decide the order before you need it.
6 min
Learn the stepsAdvancedWhen a protocol you use is exploited, the first moves are: revoke approvals, move whatever assets remain to safety, and verify the facts through official channels. Order and speed decide the outcome. There is no guarantee that losses will be compensated, and anyone offering to recover your funds is frequently the second stage of the attack.
8 min
Learn the stepsBeginnerIdentity verification generally runs: enter your details, photograph an identity document, photograph your face, then wait for the operator's review. Almost all rejections come down to two things — details that do not match the document, and photos that are not clear — so copying your address character by character and shooting in good light with the whole document in frame gets you most of the way. How long approval takes varies by operator and backlog.
6 min
Learn the stepsBeginnerOrder types split broadly into two: a market order that fills right away, and a limit order that waits for the price you name. The simple rule — limit when you are not in a hurry, market when you need the position moved for certain — covers most situations. Check which order types your exchange offers, then try each once with a small amount so you learn how they look on screen.
5 min
Learn the stepsBeginnerPlacing a limit order generally means choosing the pair, choosing buy or sell, entering a price and a quantity, and confirming. The order then sits in your order list until the market actually reaches that price. Before you place one, find out how long it stays valid and where the cancel control is, so you do not leave orders running unattended.
5 min
Learn the stepsBeginnerYour trade history records what you bought or sold, when, at what price, in what quantity, and what you paid in fees. It is the starting point for tax filing, for understanding your own results, and for any query you raise with support. Most exchanges let you export a date range as CSV or similar — save a copy at least once a year, and ideally every month.
5 min
Learn the stepsBeginnerA price alert notifies you when a coin reaches a level you set. You generally pick the coin, the price and the notification method, and save it. The value is that you stop staring at charts, which takes some emotion out of trading. But notifications can be delayed or fail to arrive, so never build a plan that depends on one.
4 min
Learn the stepsBeginnerA recurring buy purchases a fixed amount at a fixed interval automatically. You generally choose the coin, the amount, the frequency and the funding method, and save it. The benefit is that you stop making a decision every time you buy. It does not remove price risk, though, and depending on how the purchases are executed you may be paying a worse price than on the exchange-style screen.
5 min
Learn the stepsBeginnerMoving crypto between exchanges runs: get a deposit address from the receiving side, enter that address and an amount on the sending side, approve with two-factor authentication, then wait for it to arrive. A transaction sent on a blockchain cannot be recalled. Confirm both sides are using the same network, and always send a small test amount first.
6 min
Learn the stepsBeginnerAlways take a deposit address from the receiving service's own app or website and paste it with the copy function. After pasting, check the first and last few characters by eye and confirm the network matches. Because a transfer cannot be undone, this check is your last line of defence.
5 min
Learn the stepsBeginnerSome assets — XRP and XLM among them — need a destination tag or memo in addition to the address. Exchanges manage many customers behind one shared address, so without the tag there is no way to tell whose deposit it is and it will not be credited. Copy the tag from the deposit screen with the same care you give the address.
5 min
Learn the stepsBeginnerWhen a deposit does not show up, do not resend in a panic. Check on a block explorer whether the transaction has confirmed. If it has confirmed but has not credited, the usual causes are a network mismatch, a missing destination tag, or maintenance on the receiving side. Note the transaction ID, time and amount, and contact the receiving service's support.
6 min
Learn the stepsBeginnerAlways start from the contact route inside the official app or website. A contact found through a search or on social media may be a fake support channel. Before you write, gather your registered email address, when it happened, any transaction ID and what the screen showed — it cuts the number of back-and-forth replies.
5 min
Learn the stepsBeginnerBefore closing an account, the critical steps are emptying the balance and saving your trade history and annual statements. Once closed you generally cannot retrieve records, and there is no going back if you later need them for tax. The process itself normally runs: withdraw the assets, cancel open orders and recurring buys, then submit the closure request.
5 min
Learn the stepsBeginnerMost Japanese exchanges publish an annual statement summarising a year's trading, available for download from early in the following year. You normally pick the year on a statements or settings screen and download it. Formats and what they cover differ by operator, though, so if you use several exchanges or wallets, one statement will not necessarily complete your filing.
5 min
Learn the stepsBeginnerCheck the official list of supported assets on the exchange's site, together with its notices page. The same coin may be tradable on the exchange-style screen at one service and only through the brokerage-style screen at another, and whether you can deposit or withdraw it is a separate question again. New listings and delistings are normally announced in advance, so read the notices of the services you use.
5 min
Learn the stepsBeginnerAn exchange's notices page carries both planned maintenance and incident reports. Three things matter when reading one: which functions are affected — trading, transfers, login — the window it covers, and the expected recovery. When the app misbehaves, checking the notices before blaming your own device is faster, and it keeps you away from fake 'recovery support'.
4 min
Learn the stepsIntermediateThe basics for API keys are: grant the minimum permissions, restrict them to specific IP addresses, and issue a separate key per purpose. Above all, do not grant withdrawal permission unless you genuinely need it — if a leaked key cannot withdraw, the damage is contained. The secret is often shown only once at creation, so decide how you will store it beforehand.
6 min
Learn the stepsIntermediateA withdrawal whitelist restricts withdrawals to addresses you registered in advance, so even someone who takes over your account cannot send funds to their own address. Registration normally requires two-factor authentication and a waiting period — and that waiting period is the heart of the protection. Turn it on wherever your exchange supports it.
5 min
Learn the stepsBeginnerAssess an exchange on a few checkable points: whether it is registered with the FSA, how it segregates customer assets and how much it holds in cold storage, which defences it gives you as a user — two-factor authentication, withdrawal whitelists, withdrawal delays — and how it has handled past incidents. All of these can be confirmed from official disclosures and from the regulator's own publications.
6 min
Learn the stepsBeginnerA spread is the gap between the buying price and the selling price at the same moment, and it is a real cost of trading. To compare, look at both the buy price and the sell price for the same asset at the same time and note the difference. The figure moves constantly with the time of day and market conditions, so do not judge from a single observation — check repeatedly, at different times.
5 min
Learn the stepsIntermediateSlippage is the gap between the price you expected when you ordered and the price you actually got. The basics for reducing it: use limit orders instead of market orders, split large orders, avoid thin books and quiet hours, and use a slippage tolerance setting where one exists. It cannot be eliminated entirely.
6 min
Learn the stepsBeginnerWhen trading or withdrawals stop, first establish the facts and the scope from the official notices page. The cause may be planned maintenance, a system fault or a regulatory matter, and what you should do differs accordingly. The most dangerous move is reaching out to outside 'recovery help' in a panic. Keep records, and make contact only through official channels.
5 min
Learn the stepsBeginnerReach an official site from your own bookmark of the correct URL, not from the top of a search page or from an advert. Fake sites bought as search adverts is a tactic that keeps recurring. Read the domain name character by character, install apps only from the official app stores, and make checking the URL before logging in a habit.
5 min
Learn the stepsIntermediateA block explorer will tell you whether a contract's source code has been published and confirmed to match the bytecode actually running on-chain. If it is unverified, nobody outside can read what it does. But a verified badge only means the code is readable — it says nothing about whether that code treats you fairly.
6 min
Learn the stepsIntermediateBlock explorers and token analytics sites let you see who holds how much of a token. If a handful of addresses hold most of the supply, you can read the structural risk that their selling alone could break the price. What you cannot read is who those addresses belong to — holdings can be split or combined at will.
6 min
Learn the stepsIntermediateWhether the funds in a DEX liquidity pool are held in a contract that prevents withdrawal for a period is something you can check in an explorer or a locking service's records. A lock makes the overnight version of a rug pull harder. But locks have expiry dates, and once the date passes the funds can be withdrawn.
6 min
Learn the stepsIntermediateIn a block explorer you can open the destination of a transaction, follow its outgoing transfers, and step by step see where funds moved. It is useful for understanding what happened after a loss, or for checking how a project moved its money. What you can trace is movement between addresses — never who operated them.
6 min
Learn the stepsIntermediateType an address into a block explorer and anyone can see its balance, token holdings and complete transaction history. For your own address it is how you spot approvals or transfers you do not recognise; for another address it shows how long it has been active and what kind of activity it has. What it cannot tell you is anything about the person.
6 min
Learn the stepsIntermediateOn-chain analytics sites and large-transfer feeds let you see transfers above a threshold and flows into and out of exchanges. They are a clue to what is happening in a market, but the purpose behind a transfer is not recorded anywhere. Do not treat them as a way to predict prices.
5 min
Learn the stepsBeginnerExchange apps, price sites and on-chain monitoring services can all notify you when a price, a balance or an address moves. Not having to watch a screen all day genuinely reduces impulsive decisions. But alerts can be late or never arrive, and messages imitating alerts are a known scam route.
4 min
Learn the stepsIntermediateThe same asset shows different prices on different data sites and exchanges, because they aggregate different venues, weight them differently and convert currencies differently. The point of comparing sources is not to find the one true price but to understand how far a quoted price sits from the price you could actually trade at.
5 min
Learn the stepsIntermediateWhat you can establish about a project's operators comes from what they have published: the official site, documentation, company registrations and public announcements. Names and photographs are not proof of substance, and anonymity is not proof of fraud. What you can assess is how much has been disclosed and whether it hangs together.
6 min
Learn the stepsIntermediateWhether an account is official is settled by whether the project's own site or documentation links to it — not by a badge on the platform. The reverse direction, an account claiming to represent a site, proves nothing. Impersonators copy the display name, the avatar and the post history wholesale.
5 min
Learn the stepsIntermediateA public repository on a code-hosting service shows how often the code changes, how many people touch it, and how issues are handled. It is useful for checking whether the claimed state of development matches the public record. Busy activity, however, says nothing about code quality or whether the project will succeed.
5 min
Learn the stepsIntermediateDomain lookup services show when a domain was registered and when the registration was last renewed. A project claiming years of history on a domain registered weeks ago is a contradiction worth noticing. An old registration, however, does not make a site legitimate.
4 min
Learn the stepsIntermediateThe first things to find in an audit report are which version and which files were reviewed, and whether the findings were fixed. The word 'audited' on its own tells you nothing. Code changed after the audit, anything outside the stated scope, and external dependencies all sit outside what the report covers.
6 min
Learn the stepsIntermediateCheck a token's distribution twice: against the plan published in the project's documentation, and against actual balances on-chain. A pie chart alone does not show whether the plan is being followed. Scheduled unlocks matter too — they tell you when supply is due to increase.
6 min
Learn the stepsIntermediateYou can gauge gas costs from per-chain fee trackers, explorer statistics and the estimate your wallet shows before signing. Congestion can multiply the cost of the same action several times over, so checking the current level before you send is a habit worth having. An estimate still depends on conditions at execution and is not a fixed price.
5 min
Learn the stepsBeginnerYou can pull holdings scattered across exchanges and wallets into one view either with a portfolio service or with a spreadsheet you maintain yourself. Either way the purpose is the same: to see the total and to see where it is concentrated. When you use an outside service, give it as little as possible.
5 min
Learn the stepsIntermediateExchange dashboards and block explorers often provide a way to export transaction history as a file. It is the groundwork for calculating gains and for keeping records, and aligning the period, the time basis and the currency notation now saves a great deal later. What can be exported varies by service, so expect gaps.
6 min
Learn the stepsIntermediateCrypto gain-calculation tools import history from exchanges and wallets and compute gains from acquisition and disposal values. They are much faster than doing it by hand, and the more transactions you have, the more they help. But anything that failed to import or was classified wrongly flows straight into the result, so treat the output as a draft to be checked.
6 min
Learn the stepsIntermediateSites posing as airdrop eligibility checkers, and asking you to connect a wallet or sign, are extremely common. They exist to drain wallets — checking eligibility does not require a signature. Read the conditions in the project's own documentation and check only by the method the project itself publishes.
6 min
Learn the stepsIntermediateAn NFT's authenticity is settled by its contract address, not by how it looks or what the collection is called. Duplicate collections using the same images are trivial to create. The basic procedure is to take the contract address from official sources and check that it matches what a marketplace shows.
5 min
Learn the stepsIntermediateMany protocols decide changes and treasury spending through a public forum and an on-chain vote. Reading the discussion and the voting record shows what a protocol is trying to change and how concentrated the decisions are. Note that voting power usually follows token holdings, so a passed vote does not mean a sound decision.
5 min
Learn the stepsBeginnerWrite down what you checked, what it showed, and what you could not establish — at the time, not later. Without a record you repeat the same research and let memory and mood drive decisions. The ability to check things only works when paired with the habit of keeping what you found.
4 min
Learn the stepsBeginnerBefore you panic and send again, work through it in order. Start with the transaction ID on a block explorer to confirm the transfer itself went through. Then check that the network and address you used match what the receiving side specified. If both look right, it is most likely waiting to be credited on the exchange's side; if you still cannot tell, contact the official support channel with your records attached.
6 min
Learn the stepsBeginnerA pending withdrawal is usually still in the operator's own queue. Start by reading the status shown in your withdrawal history to tell whether the operator is still processing it or it has already been broadcast to the network. Once broadcast, there will be a transaction ID and you can track it yourself. If nothing moves for a long time, contact official support with your records.
5 min
Learn the stepsBeginnerThe hard part first: transfers on a blockchain cannot be reversed. As a rule, assets sent to the wrong address do not come back unless whoever controls it chooses to return them. The slim possibilities that do exist depend on who controls the destination, so identify what kind of address it was and, if it applies, raise it through an official channel. At the same time, protect yourself from the scams that target exactly this moment.
6 min
Learn the stepsBeginnerFor assets that require a memo or tag, sending to an exchange without one means the transfer succeeds on-chain but cannot be matched to your account, so nothing appears in your balance. Confirm the destination really is an exchange, then report it to official support with the transaction ID. Most operators have a process for this, but it is not guaranteed, and it can take time and cost a fee.
5 min
Learn the stepsIntermediateA transaction that sits unconfirmed is usually one whose fee is too low for current congestion. Confirm on an explorer that it really is unconfirmed, then check whether your wallet supports raising the fee or replacing the transaction. If it does not, waiting is the only option — it may go through once congestion eases, or it may eventually be dropped.
6 min
Learn the stepsBeginnerNetwork fees move with demand and, when the network is busy, can exceed the amount you wanted to send. First ask whether this has to happen now — if not, wait. Then check whether the same asset is available on another network or via a cheaper route. If it truly must go now, read the fee breakdown and the total before you confirm.
5 min
Learn the stepsBeginnerSwaps usually fail for one of three reasons: the price moved beyond your slippage tolerance, the token approval was not completed, or you do not hold enough of the network's native asset to pay the fee. Open the failed transaction on an explorer, see which kind of error it is, then work through them in order. A failed swap still consumes the fee in most cases, and that is not refunded.
5 min
Learn the stepsBeginnerA token missing from your wallet almost always means the wallet does not know to display it, not that the asset is gone. Open your address on a block explorer and see whether the balance is there. If it is, check you have the right network selected, then add the token manually if needed.
5 min
Learn the stepsBeginnerAs with tokens, separate ownership from display. Open your address on a block explorer and check whether the NFT is recorded as held there. If it is, you own it, and the problem lies with image and metadata loading or with the app you are viewing it in. Display services also take time to sync.
4 min
Learn the stepsBeginnerBefore anything else, confirm the site is genuine. Fake sites often stage a connection failure to push you toward some other action. Once you have verified it, work through the browser extension's state, whether the wallet is locked, the selected network, and any existing connection permissions. And if a screen ever asks for your seed phrase while you troubleshoot, stop there.
5 min
Learn the stepsBeginnerLockouts come down to four broad causes: a typing error, a temporary lock, a change in your device or environment, and access by someone else. Start by reopening the genuine login screen from the official app or your own bookmark. If you have received notifications about changes you did not make, treat it as unauthorised access before you attempt an ordinary password reset.
5 min
Learn the stepsBeginnerLosing the device with your authenticator app means you cannot produce codes and cannot log in. First look for the backup codes or recovery key you saved when you set it up — with those, you can recover on your own. Without them, you must apply through the operator's official channel for a reset after an identity check, which typically takes days.
5 min
Learn the stepsBeginnerIf you cannot receive mail at the registered address, you lose both notifications and the ability to reset anything. If you can still log in, changing it to a working address is the top priority. If you cannot log in, apply through the official channel for a change after identity verification. And if the address changed without you doing it, treat that as suspected unauthorised access.
4 min
Learn the stepsBeginnerAccounts get frozen for several reasons: outdated identity information, detection of suspicious activity, or checks required by law. Read the notices and your registered email first and do whatever is being asked of you. Sometimes the operator cannot explain the reason in detail, but any legitimate process runs through the official channel. Never ask a third party to get it lifted.
5 min
Learn the stepsBeginnerAn exchange password can normally be reset by starting the process yourself on the official site. A wallet password is a different animal: without the seed phrase there is nothing to restore. Confusing the two leads to the wrong response, so first be clear about which password you have forgotten.
4 min
Learn the stepsBeginnerAn app breaking after an update does not mean your assets are gone. Exchange balances live on the operator's servers, and a wallet can be restored from its seed phrase. Check the official notices for known issues first, then try restarting and reinstalling in that order — and before you reinstall anything, confirm you actually have the seed phrase to hand.
4 min
Learn the stepsBeginnerThere is no single official price for a crypto asset. Prices are set by the trades happening at each venue, and information sites typically show an average or weighted average across several exchanges, captured at slightly different times. Seeing different numbers is the mechanism working, not a fault. What you will actually pay is the figure on the order screen of the service you are using.
4 min
Learn the stepsBeginnerA limit order that does not fill either has not been reached by the market, or has been reached but your place in the queue has not come up. Check your open orders screen to confirm the order is still live, then look at where your limit sits relative to the book. Not filling is not a malfunction — it is the consequence of naming a price.
5 min
Learn the stepsBeginnerWhen more has come off than you expected, break the amount down. Trading fees, spreads, network fees and withdrawal fees are separate things that look large once combined. Go through your transaction history line by line, and if an entry still cannot be explained, take it to official support with your records.
4 min
Learn the stepsIntermediateIf you find a withdrawal or trade you did not make, speed is everything. Protecting what is still there comes first: for an exchange, request a freeze; for a wallet, move the remaining assets to a new, clean wallet. Then preserve the evidence and take it to the official channel and to a police cybercrime consultation desk. There is no guarantee that what is gone comes back.
7 min
Learn the stepsIntermediateUsing decentralised apps can leave contracts holding permission to move your tokens. That permission stays valid even at a zero balance, so it can drain tokens the moment you deposit them later. Review your approvals with a checking tool and revoke the ones you no longer use — bearing in mind that revoking itself costs a network fee.

Learn the stepsBeginnerWhere you go depends on what happened. Account and trading problems go to the official support of the service you use. Fraud and unauthorised access go to a police cybercrime consultation desk. Disputes about contracts and transactions generally can be taken to a consumer affairs centre. In every case you make the approach — treat anyone who approaches you as suspect.

Learn the stepsBeginnerCreating a wallet generally runs: get the app from its official distribution point, choose to create a new wallet, copy the seed phrase it shows onto paper, then pass the confirmation check. The setup itself takes minutes, but the thing of value is the seed phrase, not the app. Do not put funds in before you have written it down.

Learn the stepsBeginnerBacking up a seed phrase means writing the words by hand onto paper or a metal plate and storing them away from water, fire and other people's eyes. Avoid photographing them, storing them in the cloud, emailing them, or saving them in a password manager. The moment the phrase exists digitally, it goes with your device or account if either is breached.
6 min
Learn the stepsBeginnerIf a device is lost or fails, a backed-up seed phrase lets you restore the wallet on a new one. Do the restore only on the wallet app's own restore screen — never type or send the phrase to a website or to anyone claiming to be support. Afterwards, check the balance and network display calmly before doing anything else.

Learn the stepsBeginnerTo use a chain your wallet does not ship with, you register its RPC endpoint, chain ID and related values in the network settings. Take those values from the chain's own official documentation. Pasting in settings from a list site you found by searching, or from someone who sent them to you, risks having your activity observed or being pointed at a counterfeit chain.
5 min
Learn the stepsBeginnerA token your wallet does not show can be added to the list by registering its contract address. Doing so changes nothing on chain — the balance was always there, just not displayed. Take the contract address from the issuer's official site or a reputable explorer, never from a search result or an advert.
5 min
Learn the stepsBeginnerA wallet looks at one network at a time. Much of the confusion about missing balances or unreachable destinations is simply having the wrong network selected. You switch from the network indicator, typically near the top of the screen, and switching moves nothing — actually moving assets between chains requires a bridge or similar step.
5 min
Learn the stepsBeginnerYou normally read the balance from the wallet's own list, but when the display looks wrong, look your address up directly in a block explorer. The chain's record is the fact; the app's display is just one reading of it. Fiat-converted figures are indicative only and vary with the price source used.
5 min
Learn the stepsBeginnerSending runs in a fixed order: match the network, paste and verify the receiving address, check the amount and fee, then read the details before signing. Once confirmed on chain, a transfer cannot be undone — which is exactly why you send a small test amount to any new destination first.
6 min
Learn the stepsBeginnerGas cost is the work a transaction requires multiplied by the price you pay per unit of it. Your wallet shows an estimate before submission, so check the breakdown and the ceiling there before signing. Prices rise with congestion, so simply postponing anything that is not urgent lowers what you pay.

Learn the stepsIntermediateA transaction stuck in the pending state can often be pushed through by resubmitting it at the same nonce with a higher fee. Most wallets expose a function for this. It does not work on an already-confirmed transaction, it is not guaranteed to succeed, and it costs additional fees — understand all three before using it.
5 min
Learn the stepsIntermediateAn unconfirmed transaction can often be nullified by sending an empty transaction to yourself at the same nonce with a higher fee. Most wallets provide a function for this. Success is not guaranteed, a transaction that has already confirmed can never be cancelled, and the cancellation itself costs a fee.
5 min
Learn the stepsBeginnerOne seed phrase can generate several accounts, so you can split them by purpose — long-term holdings, dApp connections, receiving. Separating them means a bad approval on one account does not drag the other's assets in with it. Adding an account is usually done from the wallet's account list.
5 min
Learn the stepsBeginnerThe basic split is to keep everyday amounts in an internet-connected hot wallet and long-term holdings in a cold wallet kept offline. With that split, an accident during routine use costs you only the small balance you keep at hand. Decide the threshold by asking whether losing that amount would change your life.
6 min
Learn the stepsBeginnerNever type an address by hand: copy, paste, and compare what you pasted against the original. Checking the first and last characters is not enough — check the middle too, or use a QR code. When sending to a hardware wallet, confirming the address on the device's own screen is the most reliable check.
5 min
Learn the stepsBeginnerA watch-only wallet registers an address so you can see its balance and history. It holds no private key, so nothing can be sent from it and losing the device does not move any funds. It suits checking on long-term holdings, and setting it up needs only the address — never a seed phrase.
4 min
Learn the stepsIntermediateSigning a message proves you control an address and moves no funds by itself. That does not make every signature safe: a request presented in an unreadable format may in fact authorise a transfer of assets. If you cannot read what you are signing, do not sign it.
5 min
Learn the stepsBeginnerA signature is permission to execute what is in front of you, and there is essentially no way to take it back. Approve without reading and you lose the assets. Check five things: which site, what kind of operation, which asset and how much, the destination, and the network. If you cannot read or explain the request, do not sign.

Learn the stepsBeginnerUpdate only through the official store or a distribution route published on the developer's official site. Confirm your seed phrase backup is at hand before you start. A legitimate update never asks you to enter the phrase — if something does, it is not an update, it is a scam.
4 min
Learn the stepsBeginnerThere are two routes: create fresh keys in the new wallet and send the assets across, or use the same seed phrase on the new app's restore screen. If there is any suspicion that your keys leaked, you must take the first. Either way, revoking approvals you no longer need before moving makes the result safer.
5 min
Learn the stepsIntermediateThe honest answer is that in most cases it cannot be recovered. If the destination is an address whose keys you control, and a wallet supporting that chain can be set up, recovery is sometimes possible; if it went to an exchange, or to an address format that chain does not support, there is realistically nothing to be done. And anyone who approaches offering to 'recover' it is, almost without exception, a second scam.
6 min
Learn the stepsBeginnerIdentifying fakes is less about how the app looks than about where it came from. Open the developer's official site and follow its link to the store — keeping that order avoids nearly every same-name counterfeit. Review counts and star ratings can be bought, so do not use them as evidence.

Learn the stepsBeginnerSecuring a phone wallet starts with securing the phone. Keep the OS and apps current, set a screen lock and biometrics, and install nothing outside official channels. Then keep only everyday amounts on it, so that losing the device limits the damage rather than ending it.
