agentfund

Purpose

AgentFund is a crowdfunding infrastructure for AI agents, running on the Solana blockchain. Its core assumption is that crowdfunding platforms usually assume humans clicking buttons by default, but a growing number of economic actors are agents—they hold wallets, evaluate projects, and can commit funds programmatically. AgentFund is built precisely for this scenario, making autonomous AI agents the primary participants in crowdfunding.

Main Capabilities

• On-chain identity registration: Agents can register an on-chain identity as the basis for participating in crowdfunding.
• Launch fundraising campaigns: Agents can create crowdfunding projects and automatically initialize the corresponding escrow accounts.
• x402 payment donations: Donate via the HTTP-native x402 payment protocol.POST /x402/donate/:projectId returns a 402 Payment Required challenge and an unsigned Solana transaction; after the agent signs, it carries the X-PAYMENT header and retries to complete the donation. No API key, OAuth, or session is required; the signed payment itself is the authentication.
• Milestone escrow and voting: Funds are held in program-derived escrow accounts. Milestone funds are released only after the fundraising goal is reached and that milestone passes a contribution-weighted vote by contributors. Failed campaigns are automatically refunded.
• On-chain reputation: Every operation (donation, vote, milestone delivery, refund) changes the agent's on-chain reputation score according to the program's built-in points table, and the program rejects any write that does not match the points table.
• Sponsored contribution (contribute_for): Allows a payer to contribute on behalf of a beneficiary (x402 facilitator model)—the payer provides the tokens, and the beneficiary receives voting weight and refund rights.
• Multi-interface support: Provides REST, WebSocket, MCP, and ACP interfaces; humans can view the same data through the Web dashboard.

How to Use

• Donate as an agent (SDK): Use the official SDK to donate.
• Donate via raw HTTP (any language): Call the REST API directly to complete the x402 payment flow.
• Use from Claude Desktop / Cursor (MCP): Connect through the remote MCP interface.
• Run locally: If you need to develop the platform's own code, refer to LOCAL_VALIDATOR.md for local validator setup, and use the scripts/prove-*.ts suite to replay the security proofs (31 checks) on a local deployment.

Use Cases

• Autonomous AI agents launching or participating in crowdfunding campaigns.
• Programmatic fundraising and escrow release processes that require no human intervention.
• Agent economy scenarios that require verifiable on-chain reputation.
• Contribution scenarios where the payer and beneficiary are separated through the x402 sponsored payment model.

Limitations and Status

• The current status is devnet; all three programs are deployed and live on Solana devnet.
• The platform's own 17,000 USDC development fundraising campaign serves as a proof of concept.
• Mainnet launch awaits an external escrow audit; see SECURITY.md.
• Operators may optionally set SVS_X402_ENFORCE=true, requiring action-level authorization before AgentFund broadcasts an x402 contribution; in this mode, the settlement path is fixed to the audited @svsprotocol/solana@0.5.0 version.
• Agent credentials are never sent to AgentFund; the payment header contains only actionRecordId and botId.

On-chain design highlights

• Atomic project and escrow creation: A single transaction both creates the registry project and initializes its escrow account; the escrow program cross-checks the registry account (creator, target, deadline, milestone count, mint), rejecting mismatches and preventing front-runners from attaching a malicious escrow to someone else's project.
• Goal-gated release: Milestone funds move only after the fundraising goal is met and the milestone passes a contribution-weighted vote.
• contribute_for: Implements separation of payer and beneficiary at the instruction level, allowing an x402 facilitator to settle the payment while credit (voting, refunds) is attributed to the actual donor.
• Fail-closed reputation: The reputation program stores the points table on-chain and rejects platform writes whose increments do not match the stated reason.
