I am trying to execute the function swapExactTokensForTokens on testnet bsc user interface for the router smart contract of bsc tesnet : 0x9a489505a00cE272eAa5e07Dba6491314CaE3796

when I fill the first input field with 0.01 I dont receive 0.01 tbnb worth of the any other token, I only receive a very small amount, here is an example of a transaction I made : small amounts received but my wallet lost O.01 tbnb

I think the issue is related to some mistake I am making in the input fields :

can some one please tell me what should I write in each input field be cause I am lost at this point, thanks!!

  • amountIn: The amount of input tokens to send for swap
  • amountOutMin: The minimum amount of output tokens that must be received; use getAmountsOut(uint amountIn, address[] memory path) to determine this
  • path: Pools for each consecutive pair of addresses must exist and have liquidity
  • to: Address of who you're sending the tokens to

Amounts are in Wei = (amount ETH - or BNB in your case) x (10^18)

    thanks a lot! I have two additional question to be able to fully understand :
    1. what about the first input field named like the function : "swapExactTokensForTokens"?
    2. what if I want to swap "cake" against "XYZ" token (with existing pool) I will just need to add the two tokens adresses in the path and insert the amount of cake x10^18 in amountIn ?

  • Not sure about first field; standard Router code doesn't have that first field for swapExactTokensForTokens – Ian Moore Oct 18 '23 at 02:48
  • thanks a lot, I am still not able to understand how to go back from cake to any other token, I did the first transaction (tBNB ==> cake) and now I just want to go back but nothing is working, I flip the adresses in the path flip the value amoutIn and amountOut, nothing is working ... thank's a lot for the help. – Aniss Itaoui Oct 18 '23 at 03:23
