universal-router-sdk

This SDK facilitates interactions with the contracts in Universal Router

Usage

Install latest version of universal-router-sdk. Then import the corresponding Trade class and Data object for each protocol you'd like to interact with.

Trading NFTs

import {
  LooksRareTrade,
  LooksRareData,
  SeaportTrade,
  SeaportData
} from "@uniswap/universal-router-sdk";

// Each protocol data object contains 1 call to that protocol. Some protocols can fit
// many NFT purchase within 1 call, like seaport. Others require multiple calls per NFT (like LooksRare).
const looksRareTrades = new LooksRareTrade([looksrareData1, looksrareData2])
const seaportTrades = new SeaportTrade([seaportData1])

// Use the raw calldata and value returned to call into Universal Swap Router contracts
// Trades will happen in the order that they are handed in
const { calldata, value } = SwapRouter.swapNFTCallParameters([looksRareTrades, seaportTrades], { sender: sender.address })

Trading ERC20s on Uniswap

import { TradeType } from '@uniswap/sdk-core'
import { Trade as V2TradeSDK } from '@uniswap/v2-sdk'
import { Trade as V3TradeSDK } from '@uniswap/v3-sdk'
import { MixedRouteTrade, MixedRouteSDK, Trade as RouterTrade } from '@uniswap/router-sdk'

const options = { slippageTolerance, recipient }
const routerTrade = new RouterTrade({ v2Routes, v3Routes, mixedRoutes, tradeType: TradeType.EXACT_INPUT })
// Use the raw calldata and value returned to call into Universal Swap Router contracts
const { calldata, value } = SwapRouter.swapERC20CallParameters(buildTrade([trade]), options)
