Aequor

Aequor is a chain-abstracted USDC treasury and settlement system designed to treat multiple blockchains as a single liquidity surface. It uses Arc as the onchain authority that governs when, where, and how USDC can move, emitting settlement intents instead of performing cross-chain execution directly. A backend executor listens to these intents and uses Circle Gateway to perform native USDC mint-and-burn settlement across chains, removing the need for bridges or user-visible routing logic. Users simply authorize payouts from a shared USDC treasury, while all cross-chain complexity is handled transparently. This architecture enables seamless multi-chain payments, treasury operations, and protocol funding with deterministic execution and minimal user experience friction.

Aequor is built using a modular onchain–offchain architecture. The core logic lives in an Arc smart contract written in Solidity that acts as a USDC treasury and authority layer. Instead of bridging or swapping onchain, the contract emits chain-abstracted settlement intents via events. A Node.js backend executor (using ethers.js) listens to these events, authorizes payouts, and calls Circle Gateway to perform native cross-chain USDC mint-and-burn settlement. The frontend is a React + TypeScript app that connects via MetaMask and allows users to authorize payouts without exposing chain or bridge complexity. This separation of authorization and execution enables clean chain abstraction, safer treasury control, and a production-aligned architecture.
