1、安装python运行环境

[https://www.python.org/](https://www.python.org/)

安装完成后自行百度配置本地环境 运行你的脚本文件即可

2、代码

    import time
    from eth_account import Account
    from eth_account.signers.local import LocalAccount
    from web3 import Web3
    
    w3 = Web3(Web3.HTTPProvider("https://rpc.ankr.com/avalanche"))
    
    private_key = input("你的私钥：")
    mint_num = int(input("铸造的数量："))
    
    account: LocalAccount = Account.from_key(private_key)
    start_nonce = w3.eth.get_transaction_count(account.address)
    nonce = start_nonce
    
    def estimate_gas(txn):
        gas = w3.eth.estimate_gas({
            "from": txn['from'],
            "to": txn['to'],
            "value": txn['value'],
            "data": txn['data']
        })
        gas = int(gas + (gas / 10))  # increase 10% of the gas
        return gas
    
    def Mint(private_key):
        global account
        global start_nonce
        global nonce
    
        transaction = {
            "from": account.address,
            "nonce": nonce,
            "value": 0,
            "gas": 33036,
            "gasPrice": int(w3.eth.gas_price * 1.1),
            "to": account.address,
            # "chainId": 43114,  # Updated chainId to Avalanche Fuji C-Chain 暂时不需要链id
            "data": "0x646174613a2c7b2270223a226173632d3230222c226f70223a226d696e74222c227469636b223a226176616c222c22616d74223a22313030303030303030227d"
        }
    
        transaction.update({'gas': int(estimate_gas(transaction))})
    
        signer = account.sign_transaction(transaction_dict=transaction)
    
        tx = w3.eth.send_raw_transaction(signer.rawTransaction)
        tx_hash = Web3.to_hex(tx)
    
        # 检查交易状态
        while True:
            try:
                result = w3.eth.get_transaction_receipt(transaction_hash=tx_hash)
                if result is None or result['blockNumber'] is None:
                    time.sleep(3)
                elif result['status']:
                    print(f"[成功] - https://cchain.explorer.avax.network/tx/{tx_hash}")
                    nonce += 1
                    return result['contractAddress']
                else:
                    print(f"[失败] -  https://cchain.explorer.avax.network/tx/{tx_hash}")
                    return False
            except:
                time.sleep(2)
    
    if __name__ == '__main__':
        try:
            for i in range(mint_num):
                print("当前铸造的数量：", i + 1)
                Mint(private_key)
            print("铸造完成...")
            time.sleep(2)
        except Exception as e:
            print("报错信息如下：")
            print(e)
        sys.exit(0)
        print("程序执行完毕自动退出")
    

  
3、如何铸造别的链的铭文

在chainlist中找对应的rpc节点修改

[https://chainlist.org/](https://chainlist.org/)

（1）、修改rpc节点

    w3 = Web3(Web3.HTTPProvider("https://rpc.ankr.com/avalanche"))
    

  
（2）、修改data的16进制数据

修改其中data的数据改为需要铸造的16进制即可

        transaction = {
            "from": account.address,
            "nonce": nonce,
            "value": 0,
            "gas": 33036,
            "gasPrice": int(w3.eth.gas_price * 1.1),
            "to": account.address,
            # "chainId": 43114,  # Updated chainId to Avalanche Fuji C-Chain 暂时不需要链id
            "data": "0x646174613a2c7b2270223a226173632d3230222c226f70223a226d696e74222c227469636b223a226176616c222c22616d74223a22313030303030303030227d"
        }
    

  
（3）修改链上rpc

将其中的血崩链接改成自己的链信息即可

                if result is None or result['blockNumber'] is None:
                    time.sleep(3)
                elif result['status']:
                    print(f"[成功] - https://cchain.explorer.avax.network/tx/{tx_hash}")
                    nonce += 1
                    return result['contractAddress']
                else:
                    print(f"[失败] -  https://cchain.explorer.avax.network/tx/{tx_hash}")
                    return False
