Crypto address checker: what the chain actually says.
Paste a Bitcoin, Ethereum, Tron or Solana address. This tool verifies the format, tells you which network it belongs to, and shows the public ledger data. It does not give it a risk score, and the reason why is worth reading.
What can a free crypto address checker actually tell you?
A free address checker can verify that an address is well-formed, identify which blockchain it belongs to, and show public ledger facts such as balance and transaction count. It cannot identify who controls the address, confirm whether it is used for fraud, or tell you that funds are recoverable. Those require investigation.
Why this tool does not give an address a risk score.
Plenty of tools will show you a number between 0 and 100 next to an address. Here is why this one will not.
A score you cannot check is worse than no score
A risk score is only meaningful if you can see the model behind it: which counterparties were considered, how many hops out, how value was weighted, and how confident the attribution was. A bare number with none of that is an assertion wearing the costume of a measurement.
We publish our risk model’s weights and bands on the risk analysis page precisely so a score can be argued with.
A false “clean” result can cost somebody money
The people most likely to paste an address into a free checker are people deciding whether to trust someone. If a tool says “no risk detected” because it simply has no data, and a victim reads that as “safe”, the tool has caused the harm it appeared to prevent.
An address with no unusual public activity is not thereby safe. Most fraud addresses are brand new and look completely ordinary.
It returns facts you can verify yourself on a public explorer, and names the source of every figure. Format validation is computed locally and is correct whether or not any external service responds. Where a lookup fails, it says so rather than filling the gap with an assumption.
What each field means, and what it does not.
| Field | What it tells you | What it does not tell you |
|---|---|---|
| Format valid | The address is well-formed and its checksum verifies, so it was not mistyped. | Nothing about who owns it or whether it is safe to send to. |
| Network | Which blockchain the address belongs to. | For 0x… addresses, which EVM chain specifically — the format is shared across Ethereum, Polygon, BNB Chain, Arbitrum, Base and others. |
| Balance | What the address currently holds in the network’s native asset. | Token holdings. An address showing zero ETH can still hold significant USDT or other tokens. |
| Transaction count | How much activity the address has. | Whether that activity was legitimate. High volume is normal for exchanges; low volume is normal for a fresh scam address. |
Record it, alongside the transaction hashes, before anything else. Scam infrastructure disappears quickly, and evidence not captured in the first hours is often gone. The reporting guide sets out what to capture and where to send it.
About checking an address.
Not from the blockchain alone. Public ledger data shows what an address did, never who controlled it. Identity comes from off-chain records held by regulated services, and those are disclosed to law enforcement through legal process rather than to the public. Any tool claiming to name the person behind an arbitrary address is not doing what it says.
You largely cannot, in advance. Most addresses used in fraud are freshly generated and have no history to find. Checking the address is far less useful than checking the offer: a guarantee of returns, pressure to act quickly, an unsolicited approach, or a request for an upfront fee are all far stronger signals than anything on-chain. The warning-sign catalogue is here.
It can confirm whether the address you sent to is valid and whether the funds arrived, which is worth knowing. It cannot bring them back. A transaction to a valid address you do not control is final, and only the holder of that address can return the funds voluntarily.
Two common reasons. The funds may already have been moved on, which the transaction count will show. Or the value may be held in tokens rather than the native asset — this tool reports native balance only, so an address holding USDT will show zero ETH or zero TRX while still holding value. The explorer link shows token balances.
