Hi, I am forking uniswap, I modificated everything and deployed my contracts. I can create a liquidity pool and make a deposit, but I can't remove liquidity and swap tokens. I have this issue when i try to remove liquidity : estimateGas failed 0 removeLiquidityWithPermit, and when I swap I have the issue : Gas estimate failed, trying eth_call to extract error, with function swapExactETHForTokensSupportingFeeOnTransferTokens" Anyone knows how to solve this please ?

Do you pay enough gas? 😛

The transaction does not go to Metamask, so I can't fix the gas yet

Do you use Remix or Truffle?

I test the code in the frontend
May 20, 2021, 12:27 PM
Then it must be a issue in the frontend?

I try using remiw directly, it is not working neither, i have the issue : "code": 3, "message": "execution reverted: ds-math-sub-underflow", "data":

I have the same question. I don't know it too.

Is from/to declared?
You should replace those with recipient and sender.
@maxwellhammer may I ask, out of curiosity: why do you need a blacklist function?
Ah, that would work on ETH.
