The cryptocurrency project World Liberty Financial, supported by the Trump family, announced the launch of the AgentPay SDK, an open-source, self-hosted payment toolkit designed for AI agents. This SDK integrates self-hosted key management, policy-based transaction authorization, and can connect to popular AI development tools such as Claude Code, Codex, Cursor, and OpenClaw.

The AgentPay SDK allows AI agents to hold, transfer, and operate USD1 stablecoins on the EVM chain, with transactions locally signed. The policy engine can set per-transaction and daily limits, requiring manual approval when thresholds are exceeded. The SDK also includes built-in Bitrefill purchase functionality. World Liberty Financial stated that USD1 is positioned as the economic operating layer for autonomous AI systems, aiming to address the issue of how AI agents can make payments securely and reliably. The SDK currently supports Ethereum and BSC networks.
