How it works
Built for USDC payments
Your wallet, one account
Ethereum and Tron address formats identify the same account. Ethereum-compatible wallets can send native USDC.
Accounts and addresses →Agents with scoped access
An API token gives an agent access to an assigned wallet. Our purpose-built HSM signs transactions in a secure enclave under operator policy.
Agent Gateway →Pay for an HTTP request
x402 lets a client authorize a USDC payment for a resource. A facilitator submits the payment to POA.
x402 guide →POA supports native transfers and built-in programs; user-deployed smart contracts are not supported. Explore the architecture and security model →
