Multi-Chain Payments

Accept USDC from any chain via Circle’s CCTP V2.

Conduit uses Circle’s CCTP V2 (Cross-Chain Transfer Protocol) to accept USDC payments from any supported blockchain. The payer doesn’t need to be on Arc — they can pay from wherever they are.

Supported sending chains

Chain	Status
Ethereum Mainnet	Supported
Base	Supported
Arbitrum	Supported
Optimism	Supported
Polygon	Supported
Avalanche	Supported

You always receive USDC on Arc Network, regardless of which chain the payer sends from.

How it works

1. Payer opens your Conduit payment link
2. They connect their wallet — on any supported chain
3. They pay in USDC from their chain
4. Circle’s CCTP V2 bridges the payment to Arc
5. You receive USDC on Arc in under a second

Neither party needs to know or care about network selection. Conduit handles the routing.

Why it matters

Before Conduit, if your payer was on Ethereum and your wallet was on Arc, the payment would fail or require manual bridging. With multi-chain support there are no “wrong network” errors, no bridging required, and no failed transactions from chain mismatch.
