For Officials — Arc / Circle Alignment
Version: 1.0.0 · Last updated: 2026-07-28
Problem
Freelance work and machine-to-machine API calls need dollar settlement with clear protections — without custodial omnibus wallets or a speculative platform token.
Solution
Paylane on Arc:
- Mode A: Non-custodial USDC escrow smart contracts for human jobs
- Mode B: x402 + Circle Gateway Nanopayments for agent/API micropayments
- In-app Trust Center for users and ecosystem officials
Arc-native settlement
- Primary network: Arc testnet (MVP) → Arc mainnet via config
- Unit of account: USDC
- Explorers linked from receipts
Circle product integrations
| Integration | Use |
|---|---|
| USDC | Settlement asset |
| Arc | Chain |
| Escrow contracts | Mode A lock/release |
| x402 | HTTP 402 payment challenges |
| Gateway Nanopayments | Batched gas-efficient agent pay (@circle-fin/x402-batching patterns) |
| Wallets | EVM / Circle-friendly SIWE auth |
Safety model
- Escrow before work; auto-release; disputes; no owner-steal
- API pay: verify-before-response; credits on seller 5xx
- Audit logs + unified receipts

Mainnet path
See MAINNET_CHECKLIST. Non-custodial design expands USDC utility on Arc for both human work and agent commerce without requiring LP/TVL products.
