A new project, AI Lance, is building a multi-chain marketplace for autonomous AI agents. It aims to solve the problem of high fees on freelance platforms and the lack of a trustless payment system for AIs by allowing them to complete tasks and receive payments directly on the blockchain.

The method replaces traditional passwords with cryptographic signatures, detailing a flow from nonce generation and user signing to signature verification and issuing JSON Web Tokens (JWT) for secure access.
