World Free Finance (WLFI) announces the launch of the open-source payment development kit AgentPay SDK, designed specifically for AI agent systems. It allows AI to autonomously hold funds, execute transactions on EVM-compatible blockchains, and operate within preset strategic constraints. This release also repositions WLFI’s USD1 stablecoin as the core settlement layer for the “agent economy.”
AgentPay SDK: A Programmable Payment Framework for AI Agents
The core goal of the AgentPay SDK is to enable AI systems to interact directly with financial systems in a controlled and secure manner, eliminating the need for human intermediaries for each transaction. The SDK employs a structured three-layer processing approach, establishing clear operational boundaries between autonomy and security controls:
Core Functionality Architecture of the SDK
Fund Management and Transaction Execution: AI agents can independently manage balances and initiate transactions on EVM-compatible chains, enabling fully automated daily payments.
Strategy Constraint Evaluation: All transactions must pass policy assessments within a predefined compliance framework, ensuring AI actions stay within authorized boundaries.
High-Value Transaction Manual Approval: Transfers exceeding preset thresholds can optionally trigger manual confirmation, maintaining oversight for sensitive operations.
WLFI states that future updates will include gasless transactions, expanded cross-chain support, and a broader plugin ecosystem.
Strategic Repositioning of USD1: The Native Settlement Asset for Non-Human Traders
USD1’s market positioning differs clearly from mainstream stablecoins like USDC and USDT. While existing stablecoins focus on liquidity, regulatory compliance, or capital efficiency, USD1 is explicitly designed as a “USD-pegged asset tailored for non-human traders,” serving as an embedded payment layer within AI-driven workflows.
This shift means USD1’s target users are not individuals or institutions but autonomous AI systems executing tasks on their behalf. AI agent trading patterns are fundamentally different from human traders, requiring seamless integration into developer environments, secure key management without manual intervention, and predefined compliance controls.
The Rise of the Agent Economy: Structural Upgrades Needed in Financial Infrastructure
The release of WLFI’s AgentPay SDK reflects a broader trend in the crypto industry: AI tools are evolving from generating outputs (text, data analysis) to executing tasks (paying bills, resource scheduling, subscription management). As AI agents begin to autonomously handle financial decisions, existing financial infrastructure faces three structural needs: embedded compliance and strategy controls, secure key management without human intervention, and seamless integration with developer environments.
Through its open-source SDK strategy, WLFI aims to enable developers to build freely on its framework, attempting to establish an early ecosystem for the agent economy payment layer with USD1. Whether USD1 becomes the preferred settlement layer for AI agent systems will depend on developer adoption, cross-chain integration progress, and the ecosystem scale around the AgentPay framework.
Frequently Asked Questions
Q: How does WLFI’s AgentPay SDK differ from general payment tools?
A: The difference lies in its target users: it’s not designed for humans but to enable AI agents to autonomously perform payment tasks on the blockchain. The SDK incorporates strategy evaluation and high-value transaction approval mechanisms, allowing AI systems to operate compliantly without manual confirmation for each transaction.
Q: What is USD1’s current ranking in the global stablecoin market?
A: USD1 has a market cap of approximately $4.5 billion, ranking fifth among global stablecoins, behind USDT, USDC, and other mainstream stablecoins. WLFI is positioning USD1 as a settlement asset tailored for AI-native scenarios through the launch of the AgentPay SDK.
Q: What does the agent economy mean for crypto payment infrastructure?
A: The agent economy refers to AI systems autonomously executing financial tasks on behalf of humans. As AI agents become primary transaction entities, there is a need for programmable, strategy-aware, and human-intervention-free payment infrastructure. The openness and programmability of blockchain make it a natural platform for supporting the agent economy.

Hyperliquid rejects $1 billion in funding: Jeff Yan sticks to the no-investor principle
Hyperliquid founder Jeffrey Yan declined the financing after receiving an expression of interest from an investment of $100 million at an estimated valuation of about $1 billion, to maintain the neutrality of the agreement. He believes that bringing in outside capital would undermine users’ trust in the agreement, and chose to support operations with his personal funds. Hyperliquid’s four core principles emphasize extreme decentralization and an operating model with no outside shareholders, distinguishing it from other DeFi projects.

Bittensor founder accuses former brother of betrayal; TAO’s sudden plunge sparks 9.1 million liquidations
Bittensor co-founder Jacob Steeves accuses Covenant AI’s Simon Dare of intentionally causing damage to the agreement, leading to a sharp drop in TAO tokens. Steeves proposes a locked-staking mechanism that uses on-chain code to enforce commitments and prevent founders from making sudden, surprise exits. Even as the crisis unfolds, Bittensor’s open-source architecture can still ensure the agreement continues to operate, and it is set to hold a meeting to introduce the new mechanism.
