Hi Product Hunt 👋 I’m Buğra, the builder behind x402Shield. AI agents are starting to gain access to wallets, stablecoins, and real payment infrastructure. That creates a security problem that traditional wallet permissions were not designed to solve. The important question is no longer only: “Can this agent make a payment?” It is: “Was this agent authorized to make this exact payment?” x402Shield sits before the wallet or signer and evaluates the financial authority delegated to an agent before anything is signed. It can enforce policies around: • payment amount and daily budgets • recipient, asset, and network • wallet scope • approval thresholds • replay protection • request/payment binding Every request receives a deterministic decision: AUTHORIZED REQUIRE_APPROVAL DENIED The wallet and private keys remain under the customer’s control. We’re currently in private beta. You can explore the live demo here: https://x402shield.dev/demo I’m especially interested in feedback from teams working on AI agents, agent wallets, x402 infrastructure, autonomous commerce, and stablecoin payments.

Where should authorization live in an AI agent payment stack?

AI agents are starting to use wallets and real payment infrastructure. Being able to make a payment is not the same as being authorized to make that payment. With x402Shield, authorization happens before signing and can enforce limits for amount, recipient, asset, network, wallet scope, budgets, approvals, replay protection and request binding. I am curious how teams building agent wallets, x402 infrastructure and autonomous commerce systems approach this problem. Should authorization live inside the wallet, inside the application, or in a separate layer before signing?
