# Squid x Tenderly

Squid has worked with [Tenderly](https://tenderly.co/) 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 <https://axelar-relayer.testsquidrouter.com/api>

Polygon mainnet fork RPC <https://rpc.tenderly.co/fork/94010ea6-20cb-4a3a-b8b6-c7cb5e4574e8>

Arbitrum mainnet fork RPC <https://rpc.tenderly.co/fork/ba53ac43-0a0f-4f0a-9735-5b5de80c028f>

You can get other RPCs from this front end <https://squid-widget-git-main-v2-0xsquid.vercel.app/?apiUrl=https://axelar-relayer.testsquidrouter.com/api>

* 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)
