Crossmint: Agentic Payments Infrastructure

Crossmint is an enterprise-grade, all-in-one infrastructure platform that gives AI agents the ability to hold funds and transact autonomously. Trusted by 40,000+ clients and backed by Ribbit Capital, Crossmint provides programmable wallets, stablecoin payment rails, and commerce APIs through a single developer-friendly interface — no blockchain engineers required.

The platform provisions programmable wallets for AI agents with configurable spending limits, approval requirements, and scoped permissions. Agents can pay for tools and APIs over the x402 protocol, top up via fiat or stablecoin, and buy real-world goods through the World Store with access to 1B+ SKUs.

Agent Wallets

• Dual-key TEE architecture: the human holds one key, the agent operates with a second
• Programmable spending caps, session budgets, and merchant allowlists
• Support for 40+ chains including EVM chains, Solana, and Stellar
• GOAT (Greatest Of All Transactions) — MIT-licensed, wallet-agnostic framework

Payment Rails

• Stablecoin — USDC payments via x402 protocol, zero processing fees beyond on-chain gas
• Card networks — Visa Intelligent Commerce and Mastercard Agent Pay integration
• lobster.cash — open payment standard for AI agents, powered by Solana, Circle, Visa, Mastercard
• Fiat on/off-ramps with compliance built in

Governance Controls

• Programmable guardrails: spending limits, merchant allowlists, human approval gates
• Audit logs for every agent transaction
• Single-use credentials for scoped authority

• Your agents need to pay for APIs, data feeds, or inference calls autonomously
• You want both stablecoin and card payment rails from a single integration
• Compliance requires audit trails and spending controls enforced at the wallet level
• You are building cross-border stablecoin payment, payroll, or remittance products
• Agents need to purchase real-world goods (flights, Shopify, Amazon via World Store)

• You only need stablecoin payments on EVM chains (Coinbase AgentKit + x402 is simpler)
• You want to build your own wallet layer on raw signing infrastructure (Turnkey, Privy)
• Your agents don't transact financially
