What it does
Veto sits between your AI agents and the payment rails. Set a policy once - caps, allowlists, time windows, categories - and every payment is checked against it in real time: allowed, denied, or escalated to a human. It's not just monitoring. On crypto rails the block is enforced on-chain (a Safe + guard contract that reverts an out-of-policy transaction), and every decision comes with a signed, verifiable receipt. CLI, API, and MCP-native. Drop it in front of any agent in minutes.
Veto sits between your AI agents and the payment rails. Every action approved, denied, or escalated, with a cryptographic receipt for every decision.
Your agents can spend. Any agent can pay your business. Veto is the payment gateway built for both sides of the agent economy — every payment authorized, bounded, and signed.

In 10 minutes, your business could be discoverable and actionable for AI agents. Multi-rail — USDC on Base & Solana, plus cards. Signed receipts and buyer trust graded on every payment. Veto sits above any rail, any wallet, any agent. You define the rules — Veto enforces them. Set caps, allowlists, time windows, and more. Every payment follows your policy. Every…from veto-ai.com

delegareApr 2026 · delegare.dev · ▲70Hi guys, am building SecureLend.ai and when working on our underwriting agents (free trial, paid after) I had issues with seamless payment options. Of course I looked at x402 which I believe is a great protocol but not a fan of a) sharing private keys with the agent b) having a human in the loop or c) similar workaround e.g. pre-funded wallets So I started building out a solution. For my use case it was important to not only have stablecoins but also a fiat rail which is now implemented using Stripe. Initially I build a mandate system internally but am very glad and big shoutout to the guys…

Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
