## 1. Describe your project and how it solves a problem (max 100 words)

PACT Protocol provides trustless payment infrastructure for autonomous AI agents — the missing layer between agent capability and agent commerce. Two deployed contracts: PactEscrow v2 (service escrow with lifecycle states: Open → Funded → Submitted → Completed/Disputed) and PactPaymentChannel (bidirectional micropayment streams with EIP-712 signed vouchers). Both deployed on Arbitrum One mainnet. Our MCP server (pact-mcp-server on npm) gives any AI agent framework instant access to these capabilities. FVM deployment brings this infrastructure to Filecoin's growing agentic storage economy — agents that autonomously hire storage services need trustless payment settlement.

## 2. How does Filecoin integrate into your technical design? How does this grow on-chain activity on Filecoin?

PACT Protocol's smart contracts are EVM-compatible Solidity, deployable to FVM without code changes. This grant funds FVM mainnet deployment of:

**PactEscrow v2 on FVM** — enables AI agents on Filecoin to lock payment before work begins, release on delivery, or dispute if work is unsatisfactory. Direct use case: an AI agent purchasing storage capacity from a Filecoin storage provider agent settles payment trustlessly through PactEscrow.

**PactPaymentChannel on FVM** — enables streaming micropayments between agents (per-GB data transfer, per-compute-unit pricing). Storage providers can accept incremental payments without per-transaction overhead.

**pact-mcp-server FVM integration** — the existing MCP server (npm: pact-mcp-server@1.0.1, 13 tools for escrow and payment channel operations) will be extended with FVM chain configuration, making PACT accessible to any AI framework using the Model Context Protocol.

**How this grows Filecoin on-chain activity:** Every AI agent service transaction settled through PactEscrow generates on-chain events on FVM. The pact-subgraph will be extended to index FVM events, providing analytics on agent commerce volume. As agent-to-agent commerce grows, PACT becomes the settlement layer for that activity on Filecoin.

**ERC-8183 alignment:** PactEscrow implements the same lifecycle state machine as ERC-8183 (Ethereum's emerging standard for AI agent service escrow), positioning PACT as the standards-aligned pioneer for this use case on FVM.

## 3. Three-Month Deliverables

| Month | Deliverable | Details |
|-------|-------------|---------|
| 1 | FVM mainnet deployment | Deploy PactEscrow v2 and PactPaymentChannel to FVM mainnet. Verify contracts on Filfox. Update pact-mcp-server (new release) with FVM RPC endpoint and chain ID. Publish deployment addresses in GitHub. |
| 2 | Developer documentation | Write "PACT on Filecoin" developer guide. Deploy pact-subgraph for FVM. Publish tutorial: "How an AI agent buys Filecoin storage with trustless escrow." |
| 3 | Ecosystem activation | Run PACT micro-grant program — 5 test integrations (agents using PactEscrow on FVM, funded with PACT tokens). Publish post-deployment report with on-chain volume metrics. |

## 4. Total Grant Request

**0,000**

Breakdown:
- FVM deployment gas + contract verification: ~00
- Engineering (FVM integration, MCP server update, subgraph extension): ,000
- Documentation and developer guide: ,000
- Ecosystem activation (micro-grants for test integrations): ,500

---

## 5. Target Audience and User Engagement

**Primary:** AI agent developers building on Filecoin who need payment infrastructure for agent-to-agent services. **Secondary:** Filecoin storage providers wanting to accept AI agent clients through trustless escrow.

**Onboarding:** pact-mcp-server reduces integration to near-zero effort for MCP-compatible frameworks — install the npm package, configure FVM RPC, get 13 tools for escrow and payment channel operations. Compatible with Claude, any OpenAI-compatible agent, and Goose (Block's agent framework, which runs on the MCP standard from the Agentic AI Foundation).

**Growth:** PACT's existing Moltbook presence (61 followers), GitHub repos, and dopeasset.com/grants micro-grant program actively recruit agent builders.

## 6. Monthly Progress Updates

PACT Protocol commits to monthly GitHub progress updates in this issue thread: contracts deployed and transaction volume, documentation shipped, integrations onboarded, blockers.

---

## 7. Community Code of Conduct

PACT Protocol commits to abiding by the Filecoin Community Code of Conduct.

## 8. Program Discovery

Research into FVM ecosystem grants as part of PACT's multi-chain expansion strategy. Not a hackathon submission.

Read the three named repositories—pact-channels, pact-vibekit-plugin, and pact-subgraph—starting with their existing Arbitrum deployments, MCP integration, and event indexing setup. The proposal defines done as FVM contract deployment, an FVM-aware MCP release, an FVM subgraph, a developer guide, and ecosystem integrations, but names no individual files or tests.
