Building local AI & security tools in public

[Javier Bits • priv/acc @javierbits]

An agent handling payments on your behalf reads a job post, an invoice or a webpage, and pays what it reads. If it holds full signing keys, one injected prompt can drain the agent's wallet 🚨

So I built Tripwire at NEAR HACKATHON: a payment firewall between an AI agent and its wallet.

Tripwire puts a policy boundary between the agent and its wallet. The agent gets limited to a function-call key scoped to one vault method; the vault enforces a daily cap and allowlist on-chain; and the gateway holds anything from an untrusted source for human approval.

The rationale can be a signed @near_ai cloud inference.

This is for agent frameworks and MCP clients, agentic payment tools, wallets shipping agent modes, and DAOs or treasuries that want agents to spend without handing over the full keys.
