World Liberty Financial (WLFI) has launched the AgentPay SDK, a groundbreaking open-source toolkit designed for AI agents on Ethereum-compatible blockchains. Backed by Trump, this innovation enables autonomous self-custodial wallets, allowing AI to send, receive, and hold funds seamlessly. Transactions are executed in USD1, WLFI’s dollar-pegged stablecoin, which boasts a circulation of approximately $4.4 billion, as reported by DefiLlama.
The AgentPay architecture comprises four layers: a command-line interface, a local signing daemon, a policy engine, and a skill pack for agent integration, ensuring secure operations. Private keys are generated on the operator’s machine, ensuring local transaction signing without third-party data transmission.
To enhance security, transactions exceeding specific thresholds require human approval before proceeding. Additionally, insufficient funds trigger an error message with relevant wallet details for easy replenishment. The toolkit integrates with coding-agent hosts like Claude Code and Codex, along with a Bitrefill feature for gift card purchases, making it a versatile asset in the DeFi landscape.
