The Squeek sits in escrow until the ETH arrives. Payment and transfer settle in the same transaction — no middleman, no “send first”, a flat 0.1% fee.
Approve the escrow for one token, then list it. The Squeek leaves your wallet and waits inside the contract.
A buyer sends the exact price. The contract transfers the NFT and pays you in the same transaction.
Change your mind? The seller can withdraw the Squeek with one transaction while it is still listed.
