Deep Tide TechFlow News, March 20 — According to official sources, the crypto project related to the Trump family, World Liberty Financial (WLFI), announced the launch of an open-source AI agent payment toolkit, AgentPay SDK.

The SDK is built on USD1, integrating self-custodied key management, policy-based transaction authorization, and compatible with popular AI development tools such as Claude Code, Codex, Cursor, and OpenClaw.

AgentPay SDK allows AI Agents to hold, transfer, and use USD1 stablecoins for payments on EVM chains. Transactions are signed locally, with no data sent to WLFI, and follow a priority policy system. Each transaction must pass through a policy engine defined by the operator before signing, preventing bypass. The policy engine can set single-transaction and daily limits; exceeding these thresholds requires manual approval.

Additionally, the SDK includes built-in Bitrefill purchasing features, enabling AI Agents to directly buy gift cards, eSIMs, and prepaid cards. The policy engine can set single-transaction and daily limits, with manual approval needed if thresholds are exceeded.

As a financial infrastructure for the agent economy, AgentPay SDK aims to further promote USD1 as the economic operational layer for autonomous AI systems. In the future, WLFI will also focus on implementing EIP-3009, establishing standards, developing a plugin ecosystem, and expanding to more blockchains and partners.
