Veto - Protect your agent spending

Veto provides robust expense governance for autonomous systems interacting with payment infrastructure. Key capabilities include: * Real-time policy enforcement for transactions * Customizable spending caps, allowlists, and time windows * Cryptographically signed, verifiable receipts for every decision * On-chain enforcement for blockchain-based payments * Integration with various digital agents and payment rails Veto sits between your digital agent and payment systems, allowing operators to define and enforce spending policies with precision. Configure caps per transaction, daily, or monthly; set per-merchant limits; and utilize allowlists or blocklists. Policies can also incorporate time windows and semantic categories, providing a granular level of control over expenditures. All policy changes are versioned and immutable, ensuring a clear audit trail and easy rollbacks. Transactions undergo an eight-stage evaluation process, including pre-checks, hard policy rules, and verification. This comprehensive review ensures that every spend aligns with the operator's defined parameters, resulting in a verdict of allowed, denied, or escalated within milliseconds. For all decisions, a signed, verifiable receipt is generated, offering transparency and accountability. This tool is ideal for developers and organizations deploying autonomous agents that handle financial transactions. It ensures secure and compliant operations across diverse payment rails, from traditional systems to decentralized blockchain networks. Veto offers a critical layer of oversight, protecting against unauthorized spending and providing peace of mind.
