Transaction Hash (Tx Hash)
A unique identifier assigned to every blockchain transaction, used to look up and verify the transaction.
When you send USDC, the blockchain generates a transaction hash, a long string of letters and numbers that uniquely identifies your transfer. It looks something like: 0x3a7b...f291.
The tx hash is your receipt. You can paste it into a block explorer to see the transaction status, the amount sent, the sender and recipient addresses, the gas fee paid, and whether it succeeded or failed.
Always save your transaction hash after sending USDC, especially for larger amounts. If a transfer doesn't arrive, the tx hash is the first thing support will ask for. Most wallets show the tx hash in your transaction history.
