World Liberty Financial launches an open-source payment toolkit AgentPay SDK for AI agents

According to official news, 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 commonly used 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 EVM chains, with transactions signed locally. The policy engine can set single and daily limits, requiring manual approval for amounts exceeding the threshold. The SDK also includes a built-in Bitrefill purchasing feature. World Liberty Financial stated that USD1 is positioned as the economic operating layer for autonomous AI systems, aimed at addressing the issue of how AI agents can make payments securely and reliably. The SDK currently supports Ethereum and BSC networks.
