如何解决通过python3

这个问题与Compute uniswap pair address via python

我正在尝试做同样的事情，但对于 panckage swap v2。

我以 CAKE/WBNB 对为例：

CONTRACTS = {
    "CAKE": "0x0E09FaBB73Bd3Ade0a17ECC321fD13a19e81cE82",}

PANCAKE_SWAP_FACTORY = "0xcA143Ce32Fe78f1f7019d7d551a6402fC5350c73"
PANCAKE_SWAP_ROUTER  = "0x10ED43C718714eb63d5aA57B78B54704E256024E"

WBNB_ADDRESS = "0xbb4CdB9CBd36B01bD1cBaEBF2De08d9173bc095c"

hexadem_ ='0x00fb7f630766e6a796048ea87d01acd3068e8ff67d078148a3fa3f4a84f69bd5'
factory = PANCAKE_SWAP_FACTORY
abiEncoded_1 = encode_abi_packed(['address','address'],(CONTRACTS['CAKE'],WBNB_ADDRESS))
salt_ = pancakeswap.w3.solidityKeccak(['bytes'],['0x' +abiEncoded_1.hex()])
abiEncoded_2 = encode_abi_packed([ 'address','bytes32'],( factory,salt_))

resPair = pancakeswap.w3.solidityKeccak(['bytes','bytes'],['0xff' + abiEncoded_2.hex(),hexadem_])[12:]

# resPair is the address for the pancakeswap CAKE/WBNB pair
print(resPair.hex())
print('0xA527a61703D82139F8a06Bc30097cC9CAA2df5A6')
print(resPair.hex() == '0xA527a61703D82139F8a06Bc30097cC9CAA2df5A6')
print()

我的第一个问题是代码不起作用，它没有产生正确的合同地址，实际上它打印：

0x0ed7e52944161450477ee417de9cd3a859b14fd0
0xA527a61703D82139F8a06Bc30097cC9CAA2df5A6
False

我认为问题在于常量hexdem_的值，可以在：

hexadem_ = '0xd0d4c4cd0848c93cb4fd1f498d7013ee6bfb25783ea21593d5834f5d250ece66'#来自https://github.com/pancakeswap/pancake-swap-periphery/blob/master/contracts/libraries/PancakeLibrary.sol
hexadem_ ='0x96e8ac4277198ff8b6f785478aa9a39f403cb768dd02cbee326c3e7da348845f' # 来自 uniswap（很可能是错误的...）
hexadem_ ='0x00fb7f630766e6a796048ea87d01acd3068e8ff67d078148a3fa3f4a84f69bd5' # 来自 https://bscscan.com/address/0x10ED43C718714eb63d5aA57B78B54704E256024E#code 第 298 行

解决方法

您获取的地址是正确的。您尝试匹配的地址用于 pancake V1。你可以通过点击2个地址的“contract creator”看到这个，你会看到0x0ed7e52944161450477ee417de9cd3a859b14fd0和0xA527a61703D82139F8a97e52944161450477ee417de9cd3a859b14fd0和0xA527a61703D82139F8a06Bc5A2000000000000000000006Bc30006Bc3000000000000000000000006Bc3000000006Bc3007
