About SpendVeto
SpendVeto provides a policy engine that sits between AI agents and their wallets to govern autonomous spending. It enforces pre-payment controls such as per-call caps, hourly budgets, rate limits, and human approval thresholds before any transaction is signed. The system supports multi-chain governance across 15 chains with chain-scoped signatures and per-chain balances, including five live testnets. SpendVeto integrates via MCP middleware, allowing models like Claude to interact with tools while silently routing policy checks and payments. All settlements generate ECDSA-signed receipts for independent verification, and the full ledger can be exported to CSV for accounting. Real-time alerts and analytics track freezes, blocks, and approvals, rolling up spend data per tool and wallet. The open-source core runs headlessly with 299 end-to-end verification checks, while hosted tiers offer managed proxies, team features, and custody services for keyless agent fleets.
