## Project Summary

PACT Protocol is the trustless payment settlement layer for AI agent commerce. Two deployed contracts — PactEscrow v2 (service escrow: Open → Funded → Submitted → Completed/Disputed) and PactPaymentChannel (bidirectional micropayments with EIP-712 signed vouchers) — are live on Arbitrum One mainnet today. A published npm package (pact-mcp-server@1.0.1, 13 MCP tools) gives any AI agent framework zero-code access to these capabilities.

The problem PACT solves: when an AI agent hires another AI agent to perform a service, there is no trustless mechanism to guarantee payment for work delivered or delivery before payment. Existing solutions require human oversight, centralized escrow operators, or good-faith compliance. PACT provides fully on-chain settlement with automatic release, dispute pathways, and streaming micropayments — all accessible via the Model Context Protocol (MCP).

FVM deployment of PACT brings this infrastructure to Filecoin's native agent economy. Storage provider agents, DataDAO managers, and Filecoin compute services all need trustless payment settlement for their agentic workflows.

---

## Impact

**The problem this solves on Filecoin:**

AI agents are increasingly operating as autonomous economic actors on Filecoin — purchasing storage capacity, managing DataDAO allocations, commissioning compute jobs, and coordinating retrieval networks. These agent-to-agent transactions currently rely on trust, human approval, or custom settlement logic built per application.

PACT standardizes this. With PactEscrow deployed on FVM:

1. A retrieval agent can hire a content delivery agent, lock payment in escrow, receive the content, and release payment — all without human oversight and with full dispute protection
2. A DataDAO management agent can pay for storage renewal services with streaming micropayments via PactPaymentChannel — no per-transaction overhead, cryptographically secured
3. Any MCP-compatible AI agent framework (Claude, goose, AutoGPT, etc.) can access FVM-deployed PACT through pact-mcp-server — one npm install, zero custom Solidity

**ERC-8183 alignment:** PACT implements the same lifecycle state machine as ERC-8183 (Ethereum's emerging draft standard for AI agent job escrow). Being ERC-8183 aligned positions PACT as the standards-consistent settlement layer for FVM.

## Outcomes

### Milestone 1 — FVM Mainnet Deployment (Month 1)
- Deploy PactEscrow v2 to FVM mainnet
- Deploy PactPaymentChannel to FVM mainnet
- Verify both contracts on Filfox explorer
- Release pact-mcp-server v1.1.0 with FVM chain configuration
- Publish deployment addresses to GitHub repo and dopeasset.com

**Success metric:** Both contracts deployed, verified, and callable from pact-mcp-server on FVM mainnet

### Milestone 2 — Developer Tooling and Documentation (Month 2)
- Write "PACT on Filecoin" developer guide: complete walkthrough of agent-to-agent escrow on FVM
- Deploy pact-subgraph to The Graph Studio for FVM
- Publish integration tutorial: "How an AI agent purchases Filecoin storage with trustless escrow"
- Create reference implementation: Filecoin storage agent + PactEscrow settlement flow (open-source, MIT)
- Write AIBTC integration spec: how AIBTC multi-step agent work uses PactEscrow for settlement

**Success metric:** Developer guide published, subgraph live, reference implementation on GitHub

### Milestone 3 — Ecosystem Integration and Activation (Month 3)
- Run PACT micro-grant program for FVM ecosystem: 5 funded integrations at 1,000 PACT each
- Reach out to 3+ FVM-native agent projects for direct integration
- Publish 90-day on-chain transaction volume report with FVM-specific metrics
- Submit pact-mcp-server for listing in Filecoin developer tooling registry

**Success metric:** 5 micro-grant disbursements, 1+ live FVM integration, monthly report published

---

## Data Onboarding

The pact-subgraph extension to FVM will index all PactEscrow and PactPaymentChannel events on FVM, providing public analytics data for agent commerce on Filecoin.

---

## Adoption, Reach, and Growth Strategies

**Existing ecosystem leverage:**
- pact-mcp-server@1.0.1 on npm, referenced in AIBTC GitHub discussions
- GitHub issue filed with AIBTC team (issue #460) proposing PACT as escrow layer for multi-step agent work
- PR open on EmberAGI/arbitrum-vibekit — the Arbitrum MCP agent framework
- PR open on punkpeye/awesome-mcp-servers — most-starred MCP server directory

**FVM activation:**
- Direct outreach to top FVM agent projects on Filfox and Beryx
- PACT micro-grant campaign for FVM integrations
- Post in Filecoin Slack (#developer-grants, #fvm) upon deployment
