I'm trying to deploy UniswapV2router02 on my local ganache blockchain using truffle. I've written a migration but when I try to deploy using solc 0.6.6 it throws "UniswapV2Router02" -- Invalid number of parameters for "undefined". Got 0 expected 2!.

Does anybody know where I can find these parameters? I'm guessing they are constructors but I'm not sure what arguments they take

Etherscan names these 2 constructor arguments, but they are written in ABI so I'm not sure how to translate that to my migrations file

You can see them in the source code:
constructor(address _factory, address _WETH) public {
factory = _factory;
WETH = _WETH;
}

Ah I see

So in order to get the UniswapV2router02 contract to work I need to also have a factory contract and a WETH contract deployed right?

yes

So much work :p I guess I'll just see if I can interact with the existing contracts on ropsten

Jun 11, 2020, 2:54 PM

yeah testnets will be much much easier

Does truffle really add much if I'm trying to interact with existing contracts on Ropsten?

Or is web3 just as easy in this case?

I guess truffle is still an easy way to create all the JSON contract interfaces right?

yeah truffle does a lot of things for you (build pipelines, migrations, network configs, automated tests), ...and it uses web3 internally anyhow
