I'm trying to fork a token contract and deploy it locally using ganache but I keep running into the following error:

error

I have tried to debug the error using truffle debug 'transaction' and find the following:

debug

Now since there's no assert(), revert(), or require() statement I believe it's an out-of-gas exception error. However, one odd thing I've noticed is that after commenting out those two lines and trying to compile it still throws an error on those lines:

debug2

According to this post, comments do not affect the gas cost and I don't see how commented out code could be throwing one of the other errors.

Does anyone know what's going on here?

  • You should provide your Solidity code in question to we can understand the problem.

  • @Kiasha Hi, the code in question is linked at the very start of the post. I've simply copy pasted that code and then imported its artifact into 1_initial_migration.js and and then attempted to deploy it.

  • what means address(0) in constructor?

  • Why are you using a function in constructor that never implemented beforehand. I mean .factory() in: uniswapV2Pair = IUniswapV2Factory(_uniswapV2Router.factory()) .createPair(address(this), _uniswapV2Router.WETH());

Just before those lines I see Bonfire creating a pair on Uniswap. Did you deployed that contract as well on Ganache? is Ganache forking mainnet?

IUniswapV2Router02 _uniswapV2Router = IUniswapV2Router02(0x05fF2B0DB69458A0750badebc4f9e13aDd608C7F);

// Create a uniswap pair for this new token
uniswapV2Pair = IUniswapV2Factory(_uniswapV2Router.factory())
            .createPair(address(this), _uniswapV2Router.WETH());

    I haven't deployed that contract on Ganache or forked the mainnet. I suppose that is likely the error then?

  • Probably and this could explain the out-of-gas error. Apr 27 at 9:06
