# Swap

Exchange SOL for USDC or USDT using on-chain liquidity aggregators. Choose between direct wallet swaps or privacy-enhanced routing that breaks the link between your input and output addresses.

## Execution Modes

### Wallet Mode

Direct swap through on-chain aggregator. Client queries on-chain aggregator for best available rate across all DEXs, aggregator returns a versioned transaction with optimal routing, your wallet signs the transaction in the browser, and transaction is broadcast through a stateless proxy service.

```typescript theme={null}
// Quote request
const quote = await aggregator.getQuote({
  inputMint: SOL_MINT,
  outputMint: USDC_MINT,
  amount: inputAmount,
  slippageBps: slippageTolerance
});
```

### Private Mode

Anonymous swap through routing layer. Quote the same pair through the routing layer for privacy-enhanced execution. Send SOL to the provided temporary address. Routing layer executes the swap using its own addresses. You receive USDC/USDT from an address unrelated to your input wallet.

## Slippage Protection

Configure your tolerance for price movement during execution:

| Setting    | Tolerance    | Use Case                   |
| ---------- | ------------ | -------------------------- |
| **Auto**   | Dynamic      | Recommended for most users |
| **0.5%**   | Low          | Stable market conditions   |
| **1%**     | Medium       | Normal market volatility   |
| **3%**     | High         | High volatility periods    |
| **Custom** | User-defined | Advanced users             |

<Warning>
  Swaps that exceed your slippage tolerance are rejected before you sign the transaction.
</Warning>
