The story
Agentcard was founded to give AI agents scoped, safe payment access via single-use virtual Visa cards, positioning itself as 'Stripe for agents.' Initially built on Third National (issuer) + Stripe (funding rail via PaymentIntent holds), the company is migrating its issuing rail to Rain (stablecoin-collateralized Visa) funded by per-user Coinbase CDP wallets holding USDC on Base — deprecating the traditional card-on-file flow in favor of a crypto-collateralized model.
