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