What Is the x402 Protocol? How It Works, Top Ecosystem Projects, and How to Trade x402 Tokens on MEXC
Key TakeawaysThe x402 concept originates from a new generation of on-chain identity and portable data protocols, designed to unify user credit, behavior, and asset interactions across different Web3 applications.The x402 protocol uses cryptographic credentials, zero-knowledge proofs, and on-chain behavior verification to accumulate user reputation — meaning every on-chain action becomes meaningful and portable.Several popular x402 ecosystem projects have gained strong market attention and formed
