# App Kit SDK: Bridge

> Transfer USDC across blockchains with the App Kit SDK's Bridge capability

The [App Kit SDK](/app-kit) includes the Bridge capability that lets you move
USDC across blockchains in a few lines of code. It abstracts the underlying
[CCTP](https://developers.circle.com/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 TypeScript theme={null}
// 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](/app-kit/quickstarts/bridge-tokens-across-blockchains).

## Installation

[Install the App Kit SDK](/app-kit/tutorials/installation) to use Bridge. If you
only need to bridge and don't want to install the full App Kit SDK, follow the
