HTTP-native micropayments — AI agents pay each other per API call. Built by Coinbase.
Smart Contracts For
The Agent Economy.
AI agents that pay, trust, and hire each other —
through smart contracts we write.
Trustless AI agent identity — on-chain ID, reputation, and verification. Live on mainnet since Jan 2026.
Agent-to-agent escrow — conditional payment for work between autonomous agents. Launched Mar 2026.
Standards We Know — Standards We Know — And And When To Use Each One When To Use Each One
AI agents are entering DeFi. Smart wallets are replacing EOAs. Token standards are evolving faster than ever. We know which one to pick — because we've implemented all of them.
