According to Wu, WLFI has announced the launch of its open-source, self-custodied AgentPay SDK, which supports AI agents holding, transferring, and using USD1 for transactions on the EVM chain. USD1 is positioned as the economic operation layer of the autonomous AI system. The SDK integrates self-custodied key management, strategic transaction authorization, local signature, and plugin mechanisms. It can connect to tools such as Claude Code, Codex, and Cursor and run locally without transmitting data to WLFI. It supports policy-based automatic execution and manual approval. Currently, it supports Ethereum and BSC and pre-installs USD1, providing over 40 CLI functions and Bitrefill integration. The roadmap includes promoting gas-free transactions under EIP-3009, proposing agent payment standards, expanding the plugin ecosystem, and cross-chain and cross-border payments.
