Gas fees are transaction fees paid to miners on Ethereum.OpenSea does not receive these fees and is not able to refund them. OpenSea also doesn't control gas prices nor does it profit from them. 

Ethereum, like Bitcoin, currently uses a proof-of-work mining model. In proof-of-work, miners are decentralized computers that use their computing power to process and confirm transactions. On Ethereum, new transactions get added in "blocks" every 15 seconds. Miners are a built-in mechanism of the Ethereum blockchain and get paid in Ethereum's native cryptocurrency, ETH. 

When you pay gas fees, the payment only guarantees your transaction to be processed. It does not guarantee that the transaction will succeed.

This is because gas prices on Ethereum fluctuate widely. If there is a high level of activity on Ethereum - for example, a popular NFT collection is being released - gas prices will rise due to network congestion. In this case, the original gas fee you paid may no longer be high enough for miners to process and confirm the transaction.

Floor priceis the lowest price for collection items, rather than the average item price, and is updated in real-time. Dutch auctions are not included in floor price calculations.

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.

When you purchase an NFT on OpenSea the ownership may not immediately update.

This delay is typically due to congestion on the Ethereum blockchain. We recommend waiting a few minutes and refreshing the item’s page on OpenSea. Your wallet address should show as the owner of the item!
