Check Transaction Hash — Blockchain Transaction Verification

• Bitcoin, Litecoin, Dogecoin, Bitcoin Cash — 64 hexadecimal characters (digits 0–9 and letters a–f), no prefix.
• TRON — also 64 hexadecimal characters with no prefix: by its look such a hash cannot be told apart from a Bitcoin one.
• Ethereum and compatible networks — BNB Chain, Polygon, Arbitrum, Optimism, Base, Avalanche: the 0x prefix and 64 hexadecimal characters.
• Solana — a transaction signature in base58 encoding, usually 87–88 characters.

Since the formats overlap, the network cannot be guessed from the hash alone. The service checks the hash itself and, if it fits several networks or coins, asks you to pick the right one.

A hash has no risk score of its own — it is just the number of an operation. The risk sits with the addresses the transfer went between. So from the hash the service detects the network and the coin, shows the status, time and amount of the transfer, finds the sender and the receiver and lets you choose whose address to check.

The AML check of the chosen address gives a score from 0 to 100: up to 30 is low risk, 31–60 medium, above 60 high. The report shows where funds came into the address from, where they went next and which sources it is linked to.

• The exchange's internal request number was copied instead of the blockchain hash.
• The transfer was internal — between users of the same exchange. Such transfers often happen without a blockchain record, so there is no hash.
• The withdrawal is still being processed: the exchange shows the hash only after the transaction is sent to the network.
• A character was lost or a space was added while copying.
• The hash belongs to a network the service does not support.

A hash is public proof that a transfer took place. Exchange support and P2P counterparties ask for it, and disputes are settled by it. Sharing a hash is safe: it gives no access to the wallet.

It is not anonymous either: from the hash anyone can see the addresses of both sides and the amount, and through the addresses — the rest of their history. Keep this in mind before publishing a hash openly.

Paste the hash into the check field on the website: the status, time and amount of the transfer, the network and the sender and receiver addresses are shown straight away and for free. The full AML report for the chosen address is in your account, from $1 per check. What to do with the result once a transfer has arrived is covered on the transaction check page.
