Maestro
Give an AI agent a wallet, not a blank check.
An on-chain policy engine for AI-agent wallets. Spending limits, session keys, and a kill switch are enforced by the Solana program itself, not bypassable off-chain middleware. Ships an Anchor program, a TypeScript SDK, and an Android app.
01 · Challenge
An agent holding a key is a blank check. Off-chain guardrails are middleware, and a prompt-injected agent can route around middleware, so the limits never really existed.
02 · Decision
Put the policy where the funds are. Spending limits, session keys, allowed programs, and a kill switch live in the Solana program that holds the vault, checked on every transaction.
03 · Outcome
An agent can be fully tricked and still cannot move funds outside its policy. Shipped as an Anchor program, a TypeScript SDK, and an Android app.
