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?
x402Shield is a security and authorization layer for AI agents that can spend real money. It sits before the wallet or signer and deterministically evaluates whether an agent is allowed to make a specific payment based on amount, recipient, asset, network, wallet scope, budgets, approvals, replay protection, and request binding. Keys remain under the customer’s control.
