@voyager-gold you can discover constructor arguments concatenated to the end of the deployment transaction calldata https://goerli.etherscan.io/tx/0x73b0875358e6ea974eb9ccbaf4062e20adc9b5c605872c0eebd32d08aa9dc5f6:

I have the same question and confused. In the polygon documents they say Deploy your own ERC20 token on the root chain which means deploy my contract to goerli. But if i see the FxERC20RootTunnel constructor _fxERC20Token param is 0xDDE69724AeFBdb084413719fE745aB66e3b055C7 , which has nothing on goerli. But on mumbai testnet 0xDDE69724AeFBdb084413719fE745aB66e3b055C7 it has a contract deployed.
