  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.
