Autonomous AI systems operating in crypto and Web3 ecosystems.
Start hereThey run an observe-decide-execute loop and can settle actions on-chain under explicit limits, permissions, and goals.

Stablecoins let software agents clear payments continuously onchain, then route fiat payouts and cross-chain USDC via networks like CPN and CCTP.

X402 settles per HTTP request in stablecoins, MPP runs a pre-authorized session that batch-settles, and AP2 adds signed mandates for provable authorization.

X402 turns HTTP 402 into machine-readable payment terms, then settles signed stablecoin authorizations onchain via a facilitator.

It is a shift from buying software seats to commissioning autonomous workflows, with identity, protocols, and settlement deciding who can be trusted and paid.

Smart accounts use scoped session policies and ERC-4337 plumbing so an agent can act without holding your master key or unlimited authority.

X402 standardizes a 402-based HTTP handshake so APIs can quote, verify, and settle payments per request without user accounts.
