In order to troubleshoot issues with buying or selling your NFT, the OpenSea support team may request your "transaction hash" from a blockchain explorer.
Transaction hashes are unique IDs recording each transaction on the blockchain; this includes NFT purchases, sales, and canceled orders. All gas fees paid will generate a transaction hash.
The example below is for Etherscan, but most other blockchain explorers work in a similar way.
How do I find my transaction hash on Etherscan?
First, you'll need your wallet address. You can find this in your crypto wallet or underneath your account name on OpenSea. Make sure you're using the wallet that corresponds to the purchase.
Once you have your OpenSea wallet address, navigate to Etherscan.io and copy it into the search bar.
This will take you to the address dashboard page. On the bottom left of the page, you'll be able to see transaction hashes under the Txn Hash column.
You can click into any transaction and copy the transaction hash to your clipboard. Make sure to include transaction hashes in text (rather than screenshots) when opening a ticket with OpenSea support.
How do I find my transaction using OpenSea?
You can also obtain your transaction hash using OpenSea, in one of two places:
1. Within your wallet sidebar. Click on your wallet balance, and then select the transactions tab. You’ll see a history of transactions associated with your wallet. Click on it to navigate to the relevant blockchain explorer.
2. Within your profile activity tab. Hover over your profile icon, and click on your profile. Select the activity tab. Click on the redirect links with a time stamp to view the transaction on Etherscan directly.
