Transaction hashes are unique IDs recording each transaction on the blockchain, this includes NFT purchases, sales or even cancelling orders. All gas fees paid will generate a transaction hash.
How do I find my transaction hash on Etherscan?
First you'll need your wallet address. You can find this inside your crypto wallet, or underneath your account name on OpenSea.
Once you have your OpenSea wallet address, go to Etherscan.io and copy it into the search bar.
This will take you to the address dashboard page. You'll be able to see transaction hashes under the "Txn Hash" column on the bottom left side of the page.
Simply click into any transaction and copy the transaction hash to your clipboard. Please include transaction hashes in text (rather than in screenshots) when communicating with OpenSea support.
Thanks in advance!
