**[WLFI Announces Launch of Open-Source AI Agent Payment Toolkit AgentPay SDK]** Deep Tide TechFlow News, March 20 — According to official sources, the cryptocurrency project associated with the Trump family, World Liberty Financial (WLFI), has announced the launch of the open-source AI agent payment toolkit AgentPay SDK. The SDK is built on USD1 and integrates self-custody key management, policy-based transaction authorization, and compatibility with popular AI development tools such as Claude Code, Codex, Cursor, and OpenClaw. AgentPay SDK enables AI agents to hold, transfer, and use the USD1 stablecoin for payments on EVM chains. Transactions are locally signed, with zero data sent to WLFI, adhering to a policy-first principle. Each transaction must pass through an operator-defined policy engine before signing, ensuring no bypass. The policy engine allows for setting single-transaction and daily limits, requiring manual approval for amounts exceeding thresholds. Additionally, the SDK includes built-in Bitrefill purchasing functionality, enabling AI agents to directly purchase gift cards, eSIMs, and prepaid cards. The policy engine can set single-transaction and daily limits, with manual approval required for exceeding thresholds. As a financial infrastructure designed for the agent economy, AgentPay SDK aims to further establish USD1 as the economic operating layer for autonomous AI systems. In the future, WLFI plans to focus on the implementation of EIP-3009, standardization efforts, plugin ecosystems, broader chain integrations, and expanding partnerships.
