# WooFi

> Proactive Market Maker - off-chain price feeds with on-chain settlement

<Info>
  **Type:** PMM (Proactive Market Maker) | **Docs:** [docs.woo.org/woofi](https://docs.woo.org/woofi)
</Info>

## Overview

WooFi implements the Proactive Market Maker (PMM) model, originally developed by WOO Network. PMM combines off-chain price feeds from professional market makers with on-chain settlement, enabling near-zero slippage for retail-sized trades. Pricing is driven by WOO Network's internal market-making engine rather than passive AMM curves.

## Functions

### getWooFiPools()

Returns all active WooFi token pools on Monad.

**Returns**

| Field       | Type      | Description                         |
| ----------- | --------- | ----------------------------------- |
| `token`     | `Address` | Token address                       |
| `symbol`    | `string`  | Token symbol                        |
| `reserve`   | `bigint`  | Token reserve in the pool           |
| `price`     | `number`  | Current PMM price in USD            |
| `spread`    | `number`  | Bid-ask spread in bps               |
| `coeff`     | `number`  | Price coefficient (slippage factor) |
| `woFeeRate` | `number`  | WooFi fee rate in bps               |

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

const pools = await getWooFiPools()
for (const pool of pools) {
  console.log(`${pool.symbol}: $${pool.price}`)
  console.log(`  Spread: ${pool.spread} bps | Fee: ${pool.woFeeRate} bps`)
}
```

### getWooFiQuote()

Returns a swap quote using WooFi's PMM pricing model.

**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                                         |
| `fee`         | `bigint` | Fee charged in tokenOut                                        |
| `price`       | `number` | Execution price                                                |
| `priceImpact` | `number` | Price impact percentage (typically near zero for small trades) |

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

const quote = await getWooFiQuote(
  '0x...', // tokenIn (USDC)
  '0x...', // tokenOut (MON)
  1_000_000n // 1 USDC
)

console.log(`Amount out: ${quote.amountOut}`)
console.log(`Price: ${quote.price}`)
console.log(`Impact: ${quote.priceImpact}%`)
```

<Note>
  WooFi PMM pricing typically offers near-zero slippage for trades under \$50K. For larger trades, the `coeff` parameter (slippage coefficient) increasingly impacts execution price.
