I am trying to sign contractof Uniswapv2 on ethereum mainnet using "quote" ABI. the function is
quote(uint amountA, uint reserveA, uint reserveB)
I use c++ to make the raw transaction and send it to RPC-API(blastapi.io). But where do i find reserveA and reserveB? what contract or RPC/API call i must use to obtain the "reserveA" and "resserveB? Please help...
