IPPswap是一个基于区链的质押挖孵化器,它提供了一个简单易用的平台,使用户可以轻松地参与各种质押挖项目。
在IPPswap上,用户可以通过质押代币来获得平台的代币奖励。此外,IPPswap还提供了一个孵化器,帮助新的质押挖项
目更容易地进入市场,开发详情I762蕟O72搭9II9同时为用户提供更多的选择。
下面是IPPswap质押挖孵化器的原创编程代码示例:
导入所需的库和模块:
python
Copy code
from web3 import Web3, HTTPProvider
from solc import compile_source
from web3.contract import ConciseContract
import json
import time
设置Web3连接:
python
Copy code
# 连接到以太坊网络
w3 = Web3(HTTPProvider('https://ropsten.infura.io/v3/your-project-id'))
# 设置当前账户地址和私钥
account_address = "0x567890567890"
account_private_key = "your-private-key"
# 解锁账户开发I76案例2o72演示9II9.personal.un
w3.personal.unlockAccount(account_address, account_private_key)
编译合约源代码:
python
Copy code
# 合约源代码
contract_source_code = '''
pragma solidity ^0.4.24;
contract MyToken {
string public name;
string public symbol;
uint8 public decimals;
uint256 public totalSupply;
mapping (address => uint256) public balanceOf;
event Transfer(address indexed from, address indexed to, uint256 value);
constructor(uint256 initialSupply, string tokenName, string tokenSymbol, uint8 decimalUnits) public {
balanceOf[msg.sender] = initialSupply;
totalSupply = initialSupply;
name = tokenName;
symbol = tokenSymbol;
decimals = decimalUnits;
}
function transfer(address _to, uint256 _value) public {
require(balanceOf[msg.sender] >= _value);
require(balanceOf[_to] + _value >= balanceOf[_to]);
balanceOf[msg.sender] -= _value;
balanceOf[_to] += _value;
emit Transfer(msg.sender, _to, _value);
}
}
'''
# 编译合约源代码
compiled_sol = compile_source(contract_source_code)
contract_interface = compiled_sol['<stdin>:MyToken']
部署合约:
python
Copy code
# 部署合约开发I76案例2o72演示9II9..transact({'from': account_address})
MyToken = w3.eth.contract(abi=contract_interface['abi'], bytecode=contract_interface['bin'])
tx_hash = MyToken.constructor(1000000, 'My Token', 'MYT', 18).transact({'from': account_address})
tx_receipt = w3.eth.waitForTransactionReceipt(tx_hash)
# 获取合约地址
contract_address = tx_receipt.contractAddress
调用合约方法:
python
Copy code
# 实例化合约
contract_instance = w3.eth.contract(address=contract_address, abi=contract_interface['abi'],
ContractFactoryClass=ConciseContract)
# 调用合约方法
contract_instance.transfer("0x98765432765432",
