A TXID, short for transaction ID, is the unique identifier of one blockchain transaction. It is also called a transaction hash, TX hash or just hash. If you sent or received crypto and want to know whether it arrived, the TXID is what you look up. This page explains where to find it, where to check it, and what the result does and does not tell you. Looking up a TXID is also called a transaction hash lookup or TX hash check, and it works on the explorer of the network you used.
The format depends on the network:
0x followed by 64 characters, 66 in total.0x.0x. It looks the same as a Tron TXID, so you cannot tell them apart by the text alone. The network you used is the clue.| Network | TXID looks like | Where to look it up |
|---|---|---|
| Ethereum and other EVM chains | 0x + 64 characters | Etherscan, or the matching sister site (BscScan, Polygonscan, Arbiscan) |
| Tron | 64 hexadecimal characters | Tronscan |
| Solana | 87-88 characters (a signature) | Solscan |
| Bitcoin | 64 hexadecimal characters | A Bitcoin explorer such as mempool.space |
It shows what moved, from which address to which address, and when. It does not show who owns either address, whether the recipient is trustworthy, or whether the payment was a scam. For that you have to look at the recipient address itself: how old it is, who it has dealt with, whether it is a known exchange or a flagged address.
To do that, copy the recipient address from the explorer and paste it into Hopchain's wallet lookup. It lists the wallets and contracts that address has dealt with and marks known entities and flagged addresses. See also: how to check if a crypto address is a scam.

How do I do a transaction hash lookup?
Find the TXID in your wallet or exchange history, pick the explorer for the network you used,
paste the full hash into its search field and read the status, sender, recipient, amount and
fee.
Is a TXID the same as a transaction hash?
In practice yes. TXID, transaction hash, TX hash and transaction ID all mean the same identifier.
Can someone steal my crypto with my TXID?
No. A TXID is public information about a transaction that already happened. Never share your seed
phrase or private key, which is a different thing.
How long does it take until a TXID shows up?
Usually seconds to a few minutes after the transaction is broadcast. If the exchange has not
broadcast it yet, it will not show up until then.
Can I check a TXID without knowing the network?
Only by trying. The format narrows it down: 0x plus 64 characters is an EVM chain, a
long Base58 string is Solana, 64 plain hex characters is Tron or Bitcoin. Your exchange or wallet
history tells you which network you used.
Does Hopchain look up TXIDs?
Not yet. Hopchain starts from an address. Use an explorer to read the transaction, then paste the
recipient address into Hopchain.
