Working examples

SDK

Example of a cross-chain swap from Avalanche-AVAX to Polygon-MATIC.

First, install the Squid SDK and Squid types:

npm i @0xsquid/sdk@2.8.0-beta.0 @0xsquid/squid-types # 2.8.0-beta.0 or higher

import { Squid } from "@0xsquid/sdk"
import { ethers } from "ethers"

const userAddress = "<your address>"
const integratorId = "<your integrator id>"

const squid = new Squid({
  baseUrl: "https://v2.api.squidrouter.com",
  integratorId: integratorId
})

// initialize the Squid client
await squid.init()

const { route } = await squid.getRoute({
  fromChain: "43114", // Avalanche
  fromAmount: "10000000000000000", // 0.1 AVAX
  fromToken: "0xEEeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee",
  toChain: "137", // Polygon
  toToken: "0xEEeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee",
  fromAddress: userAddress,
  toAddress: userAddress,
  slippageConfig: {
    autoMode: 1
  }
})

const privateKey = "<your private key>"
const rpcUrl = "https://avalanche.drpc.org" // fromChain RPC URL

const provider = new ethers.JsonRpcProvider(rpcUrl)
const signer = new ethers.Wallet(privateKey, provider)

const result = await squid.executeRoute({
  route,
  signer
})

console.log(result)

API

Example for getting a route from Avalanche-AVAX to Polygon-MATIC:

const integratorId = "<your-integrator-id>"
const userAddress = "<your-address>"

const result = await fetch("https://v2.api.squidrouter.com/v2/route", {
  method: "POST",
  body: JSON.stringify({
    fromChain: 43114, // Avalanche
    toChain: 137, // Polygon
    fromToken: "0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE",
    toToken: "0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE",
    fromAmount: "100000000000000000", // 0.1 AVAX
    fromAddress: userAddress,
    toAddress: userAddress,
    slippageConfig: {
      autoMode: 1
    }
  }),
  headers: {
    "x-integrator-id": integratorId,
    "Content-Type": "application/json"
  }
})

const route = await result.json()

console.log(route)

Widget

Install the Squid Widget React component:

npm i @0xsquid/widget

And import it in your app:

import { SquidWidget } from "@0xsquid/widget"

export default function App() {
  const config = {
    companyName: "Squid Widget",
    integratorId: "<your integrator id>",
    slippage: 1,
    instantExec: true,
    infiniteApproval: false,
    apiUrl: "https://api.squidrouter.com",
  } as AppConfig;

  return <SquidWidget config={config} />
}
