In order to troubleshoot issues with buying or selling your NFT, a support team member will need 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.
Depending on the cryptocurrency used to purchase the NFT, you'll need to use the relevant blockchain explorer.
The example below is for Etherscan, but 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.
