Hi there hope you are doing great.
I’m working on a project which requires the swapping of different erc20 tokens for the merchant.
But now that I also have to include eth as a approved currency in my contract.

I’m trying to call addLiquidityETH function in uniswap V2 Router, but the transaction keeps failing.
This is the code i used to call addLiquidityETH function.

i’m trying to add liquidity in uniswap v2 router from a solidity smart contract, but it seems to fail even though the allowance have been given.
