The autonomous payment layer for AI agents. AiFinPay enables AI agents to hold wallets, make payments, and pay for services (GPU compute, APIs, SaaS) without any human in the loop.
Live on Polygon mainnet and Solana mainnet.
AI Agent → AiFinPay SDK → x402 Payment Gateway → Smart Contract → Merchant
Every agent gets:
- Agent Seat — on-chain identity + mSECCO balance
- Agent Passport — verified identity NFT for B2B payments
- mSECCO token — protocol credit unit ($1 = 100 mSECCO)
