Crossmint

Overview

Crossmint provides payments infrastructure specifically designed for AI agents, offering agent wallets, virtual cards, and hybrid stablecoin/fiat payment rails. The platform's dual-key architecture ensures that both the AI agent and the user must authorize transactions, preventing unauthorized spending while enabling autonomous operation within defined parameters. Crossmint supports both traditional payment methods (credit cards, bank transfers) and cryptocurrency (stablecoins like USDC), giving AI agents maximum flexibility in how they pay for goods and services. The platform includes programmable spending rules, transaction logging for audit trails, and APIs designed for developer-first integration. For companies building AI agents that need to make real-world purchases — from booking travel to buying supplies to paying for SaaS subscriptions — Crossmint provides the financial infrastructure layer that traditional payment processors weren't designed to handle.
