anyone know how to add liquidity to a pair created in a mainnet fork on Ethers and Hardhat?

fork from where

There is functions in router contract called addLiquidity and addLiquidityEth

Tried them, getting underflow errors. It a basic token/eth pair. Signer has both of them

you can try force the transaction, and debug it. Perhaps try replicate it on a testnet

He is using hardhat - local dev chain

i wouldn't use that to debug a transaction

sounds like a numerical error, have you checked that the types / units / decimals are all correct?

i think its possible to import it into tenderly, then debug the tx, thats how i would do it. Find out where the tx fails exactly.

if you're on hardhat then the console.log contracts are a lifesaver

or remix debugger but debuggers are midcurve imo

tenderly is underrated, debugger there is like god mode

remix debugger is useless
