CryptoAgentX

Fast, Secure Payments on Electroneum.

Comment

Inspiration

We saw the potential for AI agents to revolutionize finance, but they need the right tools to manage money securely. Electroneum’s fast, EVM-compatible blockchain and support for stablecoins like USDC inspired us to create CryptoAgentX—a financial infrastructure that lets AI agents process payments with confidence. Our aim was to build a developer-friendly platform that harnesses Electroneum’s 5-second finality, empowering AI to move USDC in real-world scenarios while keeping humans in the loop via code-level checks.

What it does

CryptoAgentX is a backend-focused platform on the Electroneum network, enabling AI agents to manage USDC transactions efficiently. It’s built for developers and offers:

AI-Driven Payments: Agents can send, receive, or split USDC using simple API endpoints. Human Oversight: Configurable API rules (e.g., approval flags) ensure humans retain control without a UI yet. Compliance Basics: Transaction limits and logs provide a foundation for safe operations. Seamless Integration: RESTful APIs and a lightweight SDK make it easy to embed in AI systems. It’s ideal for AI agents handling tasks like paying vendors, splitting costs, or processing microtransactions—all powered by USDC on Electroneum’s blockchain.

How we built it

We focused CryptoAgentX on a robust backend and blockchain integration:

Backend: Node.js with Express to expose APIs and simulate AI agent logic. Blockchain Integration: Ethers connects to Electroneum’s EVM network (via ANKR RPC) to interact with a USDC test contract and AgentBudget contract. AI Agent: We used LangChain in a Node.js environment to create an AI agent that triggers USDC transfers based on dynamic language-driven logic (e.g., 'Send 5 USDC to X' interpreted from natural language inputs). Smart Contracts: A Solidity contract Mock USDC and AgentBudget to register and send payments, deployed on Electroneum’s testnet using Hardhat. Setup: Leveraged Electroneum’s testnet and a mock USDC token for rapid prototyping. Without a dashboard, we prioritized API functionality and blockchain reliability for the hackathon.

Challenges we ran into

No Dashboard: Skipping a UI meant shifting oversight to API logic, which took extra time to design securely. Time Pressure: We learned about the Hackathon a bit late, with the March 7, 2025, deadline, we had to drop frontend plans and double down on the backend MVP.

Accomplishments that we're proud of

USDC Flow: Our AI agent successfully moves USDC on Electroneum’s testnet—fast and functional. API Simplicity: Devs on Electroneum can use our API “plug-and-play,” a big win. Secure Contract: The smart contract enforces approval rules, proving we can keep AI in check. Hackathon Speed: Delivered a working backend prototype that showcases Electroneum’s potential with AI Agent payment infrastructure.

What we learned

Backend Focus: A solid API can stand alone—UIs can wait when the core works. Electroneum + USDC: Stablecoins on ETN’s fast blockchain are a killer combo for AI-driven finance. Dev Needs: Clear endpoints and docs are more important than flashy extras. Testnet Tricks: Navigated Electroneum’s ecosystem—faucets, explorers, and EVM quirks—hands-on.

What's next for CryptoAgentX

Dashboard: Build a frontend for human oversight, showing AI actions in real-time. LLM Enhancements: Expand our ChatGPT API integration with LangChain to handle more complex payment scenarios, like negotiating splits or scheduling recurring USDC transfers. Mobile SDK: Add Android support for Electroneum’s mobile audience. Mainnet Ready: Audit and deploy on Electroneum’s mainnet with live USDC. Open Source: Share the platform and invite devs to extend it—maybe support more stablecoins or chains.
