Crossmint

Agent wallets, cards, and stablecoin payments.

How it works: A user adds a card through an embedded component and the agent requests a scoped credential. A separate smart wallet can pay for services with x402.
At checkout: Depending on the integration, a purchase can use browser automation, a merchant API or an agentic protocol. Agent Checkout was described as pre-release.
Security: Card data goes to a PCI vault; eligible cards can receive limited, single-use credentials. Crossmint says wallet permissions and limits are enforced onchain and can be revoked.
