Buying and bidding
When making a transaction with Coinbase NFT, you’ll need to go through a few different steps to complete your purchase. This includes ensuring you have enough funds to cover your purchase and gas fees as well as confirming your wallet is connected.
If you’re still having trouble, we recommend reviewing the following:
Is the NFT you attempted to buy or bid on still available for purchase? Sometimes a transaction failure occurs because someone else may have already purchased the NFT.
If you're making an offer or bid, do you have enough ETH and wETH to complete the purchase? It may be helpful to review your wallet balances before placing your offer.
Are you attempting to purchase the NFT while your wallet is set to the wrong blockchain? Currently, our marketplace only supports transactions on Ethereum with NFTs built using Ethereum's ERC 721 and 1155 standards. Check with your wallet provider for more information on switching chains, if needed.

Is your NFT minted locally on another platform? Some marketplaces offer the ability to mint your NFT without using the blockchain. As a result, your NFT will not appear on Coinbase NFT. You can find this information by checking the details section on the marketplace you used to mint or by checking your wallet address on Etherscan to see if the NFT shows among your other NFTs and assets. Please note, if it does not show in your wallet address, this means it is not currently on-chain and will only show on marketplace where it was originally created.

The file must be a JPG, PNG, MOV or another media format otherwise the file will not be accepted. Currently, our marketplace only supports minting on Ethereum with NFTs built using Ethereum's ERC-721 and ERC-1155 standard. If you’re still having trouble, we recommend reviewing the following:
