World Liberty Financial has launched AgentPay, a new open-source toolkit that enables AI agents to hold and move money on-chain. The SDK focuses on USD1, the project’s dollar-pegged stablecoin, and runs on Ethereum, BNB Chain, and other EVM networks.
What the WLFI AgentPay SDK Actually Does
AI agents can keep, transfer, and receive USD1 without giving keys to a central server thanks to AgentPay, which provides each agent with its own wallet logic. The SDK integrates a policy engine that verifies every transaction before it is sent out with self-custody key management. As part of automated workflows, agents can use it to pay for services such as digital services, in-game assets, and APIs.
Developers can load AgentPay as a plugin inside coding tools such as Claude Code, Codex, Cursor, and OpenClaw. This setup lets them build, test, and ship AI agents with payment features from the same environment they already use. The SDK works across EVM-compatible chains, so agents can talk to many existing DeFi apps and smart contracts that support USD-pegged tokens.
How AgentPay Handles Security and Controls
World Liberty Financial designed AgentPay to sign transactions locally on the user’s machine rather than sending private keys to WLFI servers. This approach reduces the risk of a single central breach and keeps keys under the developer’s control. The policy system lets teams set single- and daily-spend limits, as well as rules for which contracts or addresses an agent can use.
When an AI agent attempts to exceed its allowed limit, AgentPay can pause the payment and require human approval before it proceeds. The toolkit also includes a direct link to Bitrefill, which allows agents to buy gift cards and mobile top-ups using USD1. These features aim to support real transactions while still giving humans a way to supervise risky moves.
World Liberty Financial’s team and backers describe AgentPay as payment infrastructure for the emerging “agentic economy,” in which AI agents act as on-chain users. Analysts expect economic activity from autonomous agents to grow quickly over the next decade, but many agents still cannot send money without a manual click. By giving agents native access to USD1 on EVM networks, AgentPay tries to remove that missing step.
