The problem Trustless NFT Escrow Marketplace solves
Peer-to-peer NFT transactions require a high level of trust between buyers and sellers.
Buyers risk losing funds if the seller fails to deliver the NFT, while sellers risk transferring NFTs without guaranteed payment. Most existing NFT marketplaces rely on centralized escrow systems, introducing custody risks, additional fees, and single points of failure.
There is currently no simple, decentralized solution that allows users to trade NFTs directly with each other while ensuring secure payment, guaranteed delivery, and automatic refunds — all enforced by smart contracts.
Challenges I ran into
One of the main challenges was designing the escrow logic to handle multiple transaction states securely, including successful transfers, timeouts, and refunds, without introducing vulnerabilities such as re-entrancy or double execution.
Another challenge was ensuring that NFT ownership verification and fund release logic were synchronized correctly to prevent edge cases where either party could exploit the transaction flow.
We overcame these challenges by carefully structuring state transitions in the smart contract, using well-tested Solidity patterns, and thoroughly testing different transaction scenarios such as successful completion, cancellation, and timeout-based refunds.
