Agentic invoice escrow on Arbitrum with x402 payments, AP2-style mandates, ERC-8004-style reputation, TEE validation, service bonds, dispute evidence, and settlement receipts.
ArbiFlow is an Arbitrum Sepolia agentic invoice escrow for AI/service agents, freelancers, agencies, and merchants.
It turns a payment into a full settlement workflow: create invoice, fund escrow, attach AP2-style mandate hashes, post service bond, provide delivery evidence, request refund, attach dispute evidence, negotiate partial settlement, release/refund funds, and emit a portable settlement receipt.
The project includes x402-style payment requirements, EIP-3009 ERC20 funding, EIP-712 mandates, scoped action permits, ERC-1271 support, ERC-8004-style feedback/reputation hooks, receipt-bound validator attestations, TEE attestation hashes, MCP/agent APIs, and a live activity analytics dashboard.
Built the full ArbiFlow MVP during the buildathon: Solidity InvoiceEscrow contract, 74 passing tests with 100% coverage, Arbitrum Sepolia deployment, seed/demo scripts, Next.js UI, activity analytics, x402/EIP-3009 APIs, MCP endpoint, agent explain/simulate endpoints, receipt API, security docs, architecture docs, and submission materials.
Not fundraising. Hackathon MVP/prototype.
