A transaction hash is a unique identifier assigned to each transaction on the blockchain. It is a long string of characters that enables you to track and verify the transaction. When you send USDC to your CiNKO wallet, you receive a transaction hash that can be used to check the status of the transaction on a block explorer.

The hash is essential for tracking the progress of a transaction on the blockchain. Whether the transaction involves BTC, USDC, Ethereum, or PYUSD, the hash allows us to verify whether the transaction was successful, is pending, or has failed. Without it, we cannot track missing or delayed funds.
