Build a Multichain Treasury System on Arc: The Fintech Starter

Circle Internet Financial provides a comprehensive guide on building a multichain treasury system using USDC, Circle Wallets, Bridge Kit, Forwarding Service, and Circle Gateway through the Arc Fintech Starter. This open-source app is designed to simplify onchain treasury management by allowing users to create and manage operational wallets, move USDC between chains, consolidate balances, and execute payouts with basic controls and logging. It is particularly useful for builders of fintech applications, marketplaces, payroll systems, and AI agents that require cross-chain financial operations. By running the app locally, users can follow a structured flow to create wallets, fund them, rebalance funds across chains, unify balances into a single spendable pool, and execute cross-chain payouts. The starter app demonstrates a minimal fintech dashboard and acts as a reference architecture for building production-ready systems, encouraging developers to extend it into various financial solutions while emphasizing reliability, security, and observability.
