In short
Type 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.
Key points
- Get your bearings from three things: first transaction date, transaction count and balance
- On your own address, look for approvals and incoming tokens you do not recognise
- Do not interact with tokens or NFTs you never expected — they are sent as bait
- The history is public, but using it to identify a person is not a use we recommend
Definition
Using an explorer to inspect an address's balance, token holdings and transfer history. Everything recorded against an address is publicly readable.
Start by confirming the chain. The same address format is used across many EVM chains, so which explorer you open changes what history appears. 'Nothing shows up' is very often the wrong chain rather than an empty address.
Once the address is open, take in the summary numbers first: native balance, token holdings, transaction count and the date of the first transaction. A brand-new address and one active for years read very differently. A very low count can mean an address created for a single purpose.
Then work through the history by type. Explorers generally separate native transfers, token transfers, NFT transfers and contract interactions. If this is your own address, the entries to focus on are approvals — permissions granted in the past survive disconnecting from a site, so this is where you build the list of things to clean up.
Check what has arrived, too. Tokens and NFTs you never asked for show up in wallets. They are sent to draw curious holders onto fake sites, or to get them to connect to a malicious contract by trying to sell. The response is to leave them alone, ignore them, and hide them in your wallet's display if that helps. There is no need to send them back.
Separate what you can and cannot learn from someone else's address. You can see how long it has been active, how often it transacts and what kinds of contracts it has used. You cannot establish who holds it. Labels and exchange links tempt people into inference, but building a picture of a person from non-public attributes is not a use these articles endorse.
Watch out for
- · Posting your address publicly links your balance and full history to you
- · Do not try to sell or return unsolicited tokens and NFTs; the interaction itself is the trap
- · Do not use history to identify individuals — keep to information that has been published officially
Frequently asked questions
Can I delete my own history?
No. Chain records are designed not to be altered or removed. The practical response is to use separate addresses for separate purposes and to be careful about where you publish them.
