# KyberSwap

> DEX aggregator - smart routing across multiple Monad liquidity sources

<Info>
  **Type:** DEX Aggregator | **Docs:** [docs.kyberswap.com](https://docs.kyberswap.com)
</Info>

## Overview

KyberSwap is a DEX aggregator that routes trades through the optimal path across multiple liquidity sources. On Monad, it aggregates liquidity from native AMMs and orderbooks to provide best-execution pricing. The SDK uses the KyberSwap API for routing - no on-chain calls are required for quotes.

## Functions

### getKyberSwapQuote()

Returns an optimized swap quote via the KyberSwap routing API.

**Parameters**

| Name       | Type      | Description          |
| ---------- | --------- | -------------------- |
| `tokenIn`  | `Address` | Input token address  |
| `tokenOut` | `Address` | Output token address |
| `amountIn` | `bigint`  | Exact input amount   |

**Returns**

| Field             | Type          | Description                                                          |
| ----------------- | ------------- | -------------------------------------------------------------------- |
| `amountOut`       | `bigint`      | Expected output amount                                               |
| `amountOutUsd`    | `number`      | Output value in USD                                                  |
| `gas`             | `number`      | Estimated gas cost                                                   |
| `route`           | `RouteStep[]` | Array of routing steps `{ exchange, tokenIn, tokenOut, swapAmount }` |
| `priceImpact`     | `number`      | Price impact percentage                                              |
| `encodedSwapData` | `Hex`         | Calldata for executing the swap                                      |

```typescript theme={null}
import { getKyberSwapQuote } from 'rampart-monad'

const quote = await getKyberSwapQuote(
  '0x...', // tokenIn (MON)
  '0x...', // tokenOut (USDC)
  1_000_000_000_000_000_000n // 1 MON
)

console.log(`Amount out: ${quote.amountOut}`)
console.log(`Value: $${quote.amountOutUsd}`)
console.log(`Route: ${quote.route.map(s => s.exchange).join(' → ')}`)
```

### getKyberSwapPrice()

Returns the current spot price for a token pair using KyberSwap routing.

**Parameters**

| Name       | Type      | Description          |
| ---------- | --------- | -------------------- |
| `tokenIn`  | `Address` | Input token address  |
| `tokenOut` | `Address` | Output token address |

**Returns** `number`. price of tokenIn in units of tokenOut.

```typescript theme={null}
import { getKyberSwapPrice } from 'rampart-monad'

const price = await getKyberSwapPrice(
  '0x...', // MON
  '0x...'  // USDC
)
console.log(`KyberSwap price: ${price} USDC per MON`)
```

<CodeGroup>
  ```typescript Best Route Comparison theme={null}
  import { getKyberSwapQuote, getOpenOceanQuote } from 'rampart-monad'

  const tokenIn = '0x...'
  const tokenOut = '0x...'
  const amount = 1_000_000_000_000_000_000n

  const [kyber, openocean] = await Promise.all([
    getKyberSwapQuote(tokenIn, tokenOut, amount),
    getOpenOceanQuote(tokenIn, tokenOut, amount)
  ])

  const bestOut = kyber.amountOut > openocean.amountOut ? kyber : openocean
  const source = kyber.amountOut > openocean.amountOut ? 'KyberSwap' : 'OpenOcean'
  console.log(`Best: ${source} - ${bestOut.amountOut}`)
  ```

  ```typescript Route Inspection theme={null}
  import { getKyberSwapQuote } from 'rampart-monad'

  const quote = await getKyberSwapQuote('0x...', '0x...', 5_000_000n)
  console.log('Routing path:')
  quote.route.forEach((step, i) => {
    console.log(`  ${i + 1}. ${step.exchange}: ${step.tokenIn} → ${step.tokenOut}`)
  })
  ```
