In short
Once 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.
Key points
- Track more than balances: deposits, debts, unclaimed rewards and outstanding approvals
- A tracker only ever needs a public address — never a private key or seed phrase
- Displayed valuations are approximations from a price source, not what you could actually sell at
- For tax purposes you still need your own record of dates, amounts and prices
Definition
Maintaining a continuous view of the addresses you control — balances per chain, deposits into protocols, outstanding debts, unclaimed rewards and live approvals.
Begin by writing down how many addresses you actually control: exchange accounts, your main wallet, the wallet you use to try new dApps, hardware wallets. Note which chains each one operates on and what it is for. Without that, no tool will give you a complete picture.
Then examine what is in each. A block explorer covers plain balances, but a portfolio tracker is far more practical for seeing positions across several chains and protocols at once. Such tools need only a public address; a private key or seed phrase is never required. Anything that asks for one should be abandoned on the spot.
What you check is not only balances. Include assets deposited into protocols, outstanding debts, rewards not yet claimed, and approvals you have granted. Approvals in particular never appear in a balance listing, yet they are the single most exploited route to losing assets. Make them a standing item in the review.
Read valuations carefully. The figure a tool shows is an estimate derived from its price source. For a thinly traded token, you cannot necessarily sell that quantity at that price; what you would actually realise depends on pool depth and your size. Rather than taking comfort in a total, treat 'can this be converted' as a separate question.
Finally, records for tax. A tracker shows the present state; the date, quantity and price of each past transaction is something you must capture separately. On-chain history persists, but reconstructing everything afterwards is laborious, and interfaces disappear when protocols shut down. Noting each transaction as it happens is, in the end, the most reliable method.
Watch out for
- · Sites posing as trackers exist to collect private keys or seed phrases. Viewing requires only a public address
- · Displayed valuations are approximations; a thin token may not sell at the price shown
- · Balance listings do not reveal approvals. Assets under a lingering approval can be moved at any time
Frequently asked questions
Does entering my address into a tracker expose my identity?
Addresses and their histories are already public, so entering one does not disclose anything new. What it does create is a record, held by that service, linking several of your addresses to one user. How much you allow to be connected — including to a KYC-verified exchange account — is a decision to make deliberately.
