World Liberty Financial Launches Toolkit to Let AI Agents Spend USD1

World Liberty Financial ($WLFI) on Thursday released the AgentPay SDK, an open-source toolkit that enables AI agents to autonomously hold, send, and receive funds across Ethereum-compatible blockchains.

Transactions are settled in $USD1, $WLFI‘s dollar-pegged stablecoin, which currently has roughly $4.4 billion in circulation, according to DefiLlama.

How It Works

AgentPay’s architecture spans four layers: a command-line interface, a local signing daemon, a policy engine, and a skill pack for integration with agent hosts. According to $WLFI‘s documentation, private keys are generated and stored on the operator’s machine, and all transaction signing occurs locally — the SDK sends no data to $WLFI or any third party.

When a transaction exceeds preset thresholds, the SDK pauses it and requires human approval before proceeding. If a wallet lacks sufficient funds, the system halts the operation and returns an error including the wallet address, chain ID, and a QR code for replenishment.

The kit plugs directly into coding-agent hosts, such as Claude Code, Codex, and OpenClaw, according to the project’s documentation. It also includes a built-in Bitrefill integration that allows agents to purchase gift cards and mobile top-ups with $USD1.
