The AgentPay SDK allows AI agents to send funds and settle transactions while performing assigned tasks. Developers can use the system to enable agents to pay for APIs, services, and digital products during execution.
World Liberty Financial has built the SDK with defined transaction controls that regulate how payments execute. Operators can set per-transaction limits and daily spending caps within the system. The SDK executes transactions automatically when payments remain within defined limits. The system requires manual approval through the command line when transactions exceed set thresholds.
The SDK verifies wallet balances before it initiates any transaction to prevent execution errors. The system halts the transaction when the wallet does not hold sufficient funds. The SDK generates a QR code that allows users to top up their wallets immediately.
The SDK signs transactions locally through Unix domain sockets to protect private keys from exposure. The system keeps private keys inside the local environment during all operations. The SDK does not expose keys to agents, external services, or third-party tools.
The SDK includes more than 40 command-line functions that support wallet management and token transfers. Developers can use the system to run RPC queries, configure relays, and manage backups. The SDK allows agents to purchase digital goods such as gift cards and eSIMs through Bitrefill integration. World Liberty Financial has released the full SDK as open-source software on GitHub.
WLFI Launches AgentPay SDK as USD1 Gains Ground in AI Payment Infrastructure
World Liberty Financial employs USD1 as a settlement currency in the AgentPay system to facilitate transactions using AI. The company has programmed USD1 on both Ethereum and Binance Smart Chain to maintain constant use. The stablecoin shares the same contract address in both networks to make deployment easier.

Since its launch in March last year, USD1 has reached a circulating supply of between $3.3 billion and $4.5 billion. The stablecoin is now among the five biggest dollar-backed assets by market value.
Meanwhile, World Liberty Financial has applied for a national trust bank charter with the OCC to expand its control over financial operations. The company plans to manage issuance, custody, and conversion within a single structure.
Several firms are developing systems that connect AI tools to payment infrastructure across the industry. Circle is building payment systems that support agent-based transactions. Stripe is also developing a blockchain that focuses on stablecoin payments. Meanwhile, Coinbase has introduced a standard that enables agent-driven payment systems.
What Comes Next for Agent-Based Financial Systems and Crypto Payments
World Liberty Financial plans to introduce EIP-3009 to allow AI agents to execute gasless transactions without holding native tokens. This feature will simplify payment execution across blockchain networks. The update will reduce friction for agents that need to complete transactions frequently.
The company is developing interfaces that allow AI agents to follow defined policies during execution. World Liberty Financial is preparing research that focuses on security risks in AI-based payment systems. The roadmap includes a plugin system that developers can use to extend SDK functionality.
