How do I buy a fixed-price item?

Updated September 21, 2026

  1. Open the item and choose Buy now.
  2. Review the sheet: price, creator earnings, the 0.5% marketplace fee, estimated gas, and the total. If you are on the wrong chain the app asks you to switch.
  3. Confirm in your wallet.

The transaction pays the seller and transfers the item to you in one on-chain step. It is final once confirmed. If the listing was filled by someone else a moment earlier, your transaction fails and only gas is consumed.

Some items are listed in a token (for example WETH or USDC) rather than the native currency; the sheet shows which, and your wallet may need a one-time approval to spend that token.
