HexaNode

AI agents already act autonomously for users and companies such as booking trips, managing calendars, and handling support. The next step is agents that trade on our behalf, representing us in markets and supply chains. We want to build that future. HexaNode is an early implementation of that future on Chainlink.
HexaNode is an autonomous procurement system for the Chainlink CRE & AI track. It detects when inventory (e.g., milk in a supermarket) falls below a threshold, finds suppliers from a config-driven catalog, negotiates terms with that agent (with deepseek as the underlying AI), and settles via x402 payments, with on-chain settlement on Ethereum Sepolia.
What problem it solves: Manual procurement is slow and error-prone. As more agents act for users and companies, they need to procure goods and services without human intervention. HexaNode automates the full flow, need detection, supplier discovery, negotiation, payment, and verification, so agents can trade on behalf of their owners.
How it works: A CRE workflow runs a 5-state loop: (1) needDetected scans inventory config for items below threshold; (2) search matches providers by product; (3) negotiate uses DeepSeek to produce structured terms; (4) payment performs the x402 handshake (provider returns 402, workflow pays, provider releases fulfillment); (5) verified checks fulfillment and optionally records it on-chain via HexaNodeRegistry. We’re building the infrastructure for agent-to-agent commerce on Chainlink.

• Chainlink CRE – Workflow orchestration with Cron trigger, HTTP client, and EVM client
• DeepSeek – LLM for structured negotiation terms
• x402 – HTTP 402 payment handshake with a local provider server
• Ethereum Sepolia – HexaNodeRegistry and HexaNodePaymentReceiver for on-chain settlement
• Config-driven – Inventory, providers, and thresholds in JSON; no hardcoded business logic
• Web UI – React dashboard for agents and inventory; API docs for the infra API
