Deposit USDC to Unified Balance
Deposit USDC into your Arc Unified Balance using the official Circle Unified Balance Kit across any supported chain.
Powered by @circle-fin/unified-balance-kit. Allows aggregating USDC across source chains (Base, Ethereum, Polygon, Arbitrum, Avalanche) and routing unified liquidity directly into Arc Mainnet.
Depositing directly on Arc Mainnet requires only 1 block confirmation (~1–2 seconds). Your Unified Balance is indexed almost instantaneously without cross-chain rollup delays.
USDC in your personal Base or Arc wallet is held directly by your address. To become part of your Circle Gateway Unified Balance, you must deposit it into the official Circle Gateway contract (0x7777...00eE). Once deposited, it is unified across chains for instant, zero-gas nanopayments.
