bscLink 可以去 chainList找
正式區/測試區都有連結

abi要去智能合約複製
https://testnet.bscscan.com/address/0xB1ba07780285D26d2E90E69527dE2493a84e6C3a#code

address是智能合約地址

Web3 Contract Read

contract.functions.getMyRobot
是呼叫智能合約getMyRobot的func

 reward = contract.functions.getMyRobot('0x01010129b1FcB9b01b3f0B345681C3rA8aa0c48A5').call()
 print("reward = ", reward)

Web3 Contract Write

myAddress你的錢包地址
privateKey你的私鑰
nonce隨機數

contract.functions.createRobot
是呼叫智能合約createRobot的func
裡面有兩個參數_ref,_amount

myAddress = "0x01010129b1FcB9b01b3f0B345681C3A8aa0c48A5"
privateKey = "0x3e80675a40058c7efb369c510c197e22"
nonce = bscWeb3.eth.getTransactionCount(myAddress)
transaction = contract.functions.createRobot(_ref=myAddress, _amount=10000000000000000000).buildTransaction({"chainId": 97, "from": myAddress, "nonce": nonce})
print(transaction)
signedTxn = bscWeb3.eth.account.sign_transaction(transaction,privateKey)
txHash = bscWeb3.eth.send_raw_transaction(signedTxn.rawTransaction)
txReceipt = bscWeb3.eth.wait_for_transaction_receipt(txHash)
print(txReceipt)
