Trump-backed WLFI  launches AgentPay SDK open-source payment toolkit for AI agents

The Trump family has expanded its presence in the crypto community with a major development for artificial intelligence (AI) agents. According to reports, World Liberty Financial (WLFI) has rolled out AgentPay SDK, a first-of-its-kind open-source software development kit for empowering AI agents financially.

In an announcement on X, Donald Trump Jr. highlighted the idea behind the product: that AI agents should do more. He asserts, “AI agents that can reason but can’t pay for anything are just expensive interns.” 

What does AgentPay SDK offer the crypto market?

In the spirit of Satoshi Nakamoto’s decentralization, WLFI has introduced a payment method that respects users’ privacy. According to the team, “It works inside the coding tools users already use. It runs on your machine, not ours, and sends zero data to WLFI.”

The launch is a concrete fulfillment of the promises Co-Founder Zak Folkman hinted at just eight days ago, when he teased that something big was in the works for AI-powered payments. The architecture is built upon a basic principle: Agents can transact, but humans control the rules.

As per WLFI, AgentPay SDK offers features such as self-custodial key management, policy-first transaction authorization, and, via its plug-in functionality, integration with the tools that users already use to build their agents: Claude Code, Codex, Cursor, OpenClaw, and others.

How does the operational process look?

The policy engine allows setting per-transaction and daily spend limits. Transactions under the limit are executed automatically. Transactions over the limit are suspended and wait for manual approval via the CLI. 

If the wallet is low on funds, the SDK stops its execution, indicates what is missing, and provides a QR code for mobile top-up instead of a failed transaction, thus saving gas.

According to the official announcement, signing is done locally using Unix domain sockets. The private key is never sent to the agent, the skill pack, or any external service. WLFI stressed repeatedly: no data is sent to the company.

USD1 is pre-configured for Ethereum and BSC, using the same contract address on both networks. It is also pre-configured for additional EVM networks.

In case of a shortage, “The SDK doesn’t retry a doomed transaction. It stops and shows your agent exactly what’s needed: wallet address, network, chain ID, which assets are short, and a QR code for mobile top-up. The agent relays that information back to you.”

Why autonomous agent economics matter

The ecosystem for crypto and AI is contributing to the sense of urgency for Circle, as they work on blockchain infrastructure and nanopayments for agents. Stripe is working on its blockchain, Tempo, for stable payments.

Coinbase has created an incubated open standard, x402, for agent-based payments. Shopify is working on stable payments.

OpenAI has hired the creator of the autonomous-agent framework, OpenClaw. 

The Winklevoss twins’ Gemini Exchange offered a similar sentiment in their shareholder letter this week. They emphasized that “AI is money for machines” and announced the addition of Model Context Protocol (MCP) as a fourth API interface for AI agents.

WLFI’s crypto investments targeted by political antics

USD1 investments have raised eyebrows among critics, including Democratic lawmakers such as Senator Elizabeth Warren and Representative Maxine Waters. 

Binance has also been caught up in the controversy. The stablecoin gained significant impetus after a $2 billion investment into Binance by MGX was settled in USD1, a fund based in Abu Dhabi. Binance currently owns approximately 87% of the stablecoin’s total supply. 

WLFI has filed for a National Trust Bank charter with the OCC. This will enable them to internalize the issuance, custody, and conversion of the stablecoin. 

WLFI has provided a roadmap for the SDK’s further development. The next step in the roadmap is implementing EIP-3009. This is a gasless meta-transactions protocol that enables agents to transact without gas tokens. This is a key development in enabling autonomous transactions. 

Other developments in the roadmap include the filing of an EIP for a policy-aware agent interface, a white paper on the security of AI agent payments, a plugin architecture for extensions, and further development in the realms of cross-border payments, FX, remittance, settlement, and DeFi protocol.
