Squid x Tenderly

Mainnet fork dev environment

PreviousChoose How To Integrate SquidNextTestnet or Mainnet?

Last updated 1 year ago

Squid has worked with to build a powerful cross-chain development environment. This environment is a replicated Mainnet fork of most Squid-supported EVM chains. This lets users and developers test using mainnet liquidity, and is our recommended development environment.

You can spend funds from your account in this environment without spending them on mainnet.

Mainnet fork environment base URL

Polygon mainnet fork RPC

Arbitrum mainnet fork RPC

You can get other RPCs from this front end

  • Try connecting your wallet and clicking “switch network” on the source wallet. Metamask should pop up with the new chain config (MAKE SURE YOU DON'T SUBMIT TO REAL MAINNET)

Users can test swapping in our dev environment

Set your base URL to

Set your base URL to

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

(async () => {
  // instantiate the SDK
  const squid = new Squid();

  squid.setConfig({
    baseUrl: "https://axelar-relayer.testsquidrouter.com/api", // for testnet use "https://testnet.v2.api.squidrouter.com"
    integratorId: "your-integrator-id"
  });

  // init the SDK
  await squid.init();
  console.log("Squid inited");
})();
const baseUrl = "https://v2.api.squidrouter.com/v2"

You can use Tenderly's block explorer and debugger on any transaction submitted to these RPCs.
