  1. Thank you for your article. I have faced with unknown problem while deploying PancakeRouter (Main Router)
    It shows smth like (testnet):

    “`
    Deploying ‘PancakeRouter’
    ————————-
    > transaction hash: 0x8c5158a71173550a53f0e7a77ba0362e2f4e1d83a049f400327a44d6061dc7c4

    Error: *** Deployment Failed ***

    “PancakeRouter” — Cannot create instance of PancakeRouter; no code at address 0x73c8a3Bbd746E9C258859E4c744f27Ec21958f9e.
    “`
    and ‘no code at address’ part changing address everytime when I trying to deploy the contract.

    I am using truffle in order to deploy to the testnet(binance testnet).

  2. Hi,

    Thank you for this amazing tutorial,

    I have made the steps in this tutorial, but it seems that something is wrong, because the Cake token price is gotten from PancakeSwap when doing a simple swap between BNB to Cake.

    Might I know why this problem is orruring please ???

    King regards

  3. Thank you. When I tried to run it in my own geth, I cannot deploy contracts with iUniswap interface, whenever I call:

    IUniswapV2Router02 _uniswapV2Router = IUniswapV2Router02(0xA166ddFA31756C8e66C9e2971D0DC843E9D68a60); // Router address deployed as per nhancv method

    I get:

    {
    “code”: -32000,
    “message”: “execution reverted”
    }

    Do you have any suggestion to me?

  5. Hello,

    Thanks for your great information. Followed your guide and worked. May I ask what are the procedures to put it on the bsc main net (not testnet)?
    For example:
    supportedChainIds 97 back to 56?
    switch .env to production one?

    Thank you very much

  6. Hey, thank you very much for your tutorial. I have a question how did you deploy the site? Can you make a tutorial also or point out how to do it? I really appreciate any help you can provide.

  7. For those that have gotten this to work. What Linux did you install it on? Centos does not like it. Errors on final compile.
