Binance smart chain expert -- 2

I have a working javascript that swaps two tokens on PancakeSwap. I have successfully exchanged WBNB for BUSD on mainnet. WBNB → BUSD works on all tests. The problem is that the code is not robust and does not work with all tokens.


Main task: That the exchange between any two tokens works in a robust way given a pair of tokens and the amount of the input token. If the token has lp in pancakeswap it has to do the exchange correctly.

Gas calculation of the transaction dynamically (it is set with a constant now)

Dynamic tokens decimal calculation.

Analyze the code in detail and prevent possible problems that may occur.

Test the code in detail in a large amount of tokens.

Important: I will be extremely rigorous in giving the job as finished. It has to work correctly on at least 24 out of 25 tokens. An expert is required. If you are not an expert, do not bid so that we do not waste any time.
