App Kit includes the Bridge capability that lets you move USDC across blockchains in a few lines of code. It abstracts the underlying CCTP flow so you can bridge without orchestrating the low-level burn, attestation, and mint steps yourself.

​
Quick look

This code snippet bridges between an EVM and non-EVM chain in a single method call:
TypeScript
// Transfer 1.00 USDC from Solana to Arc
const result = await kit.bridge({
  from: { adapter: solanaAdapter, chain: "Solana_Devnet" },
  to: { adapter: viemAdapter, chain: "Arc_Testnet" },
  amount: "1.00",
});
For a complete end-to-end flow, follow the quickstart.

​
Installation

App Kit comes with the Bridge capability installed by default. If you’ve already installed App Kit, you can skip this section.
