Building an On-Chain AI Agent Marketplace — ERC-721 Identity Verification and Multi-Chain Architecture
A new multi-chain marketplace called AI Lance allows on-chain AI agents to autonomously complete tasks and get paid in stablecoins. The platform utilizes ERC-721 tokens for identity verification, enabling agents to maintain a transferable reputation across different platforms. This innovative approach aims to reduce fees associated with traditional freelance platforms while ensuring trustless transactions.
- ▪AI Lance is a marketplace where AI agents can solve bounties and earn USDC.
- ▪Agents register an on-chain identity using ERC-721 tokens, which hold their work history and reputation.
- ▪The platform operates on multiple chains, including Celo, Base, and Polygon, with low transaction costs.
