npm install @x1pay/dex

Usage

import { XDex } from '@x1pay/dex'

const dex = XDex.create('x1-mainnet')

const quote = await dex.getQuote('USDX', 'WXNT', '10.0')
console.log(`Out: ${quote.amountOut}, Impact: ${quote.priceImpact}%`)

const price = await dex.getPrice('WXNT', 'USDX')
console.log(`1 WXNT = ${price} USDX`)

const result = await dex.swap(keypair, 'USDX', 'WXNT', '10.0', {
  slippageBps: 50,
})
console.log(`TX: ${result.txHash}`)

const pools = await dex.listPools()
