首先，大家要在以太坊钱包中选择要存入的ETH，，然后复制该货币的地址。登录到您的 Coinbase 账户，点击“存款”按钮，在以太坊区块链中选择 L2 Base。您会看到一个交互式代码框，包含以下信息：deposit(address l2Bridge, uint256 amount) 3、将您在第1步中复制的货币地址粘贴到交互式代码框中的“l2Bridge”字段中。 4、将您要存入的货币数量输入到交互式代码框中的“amount”字段中。 5、点击“提交”按钮，等待交易完成（通常需要几分钟）。 存款示例, 以下是Python3的代码示例:""" 安装依赖 pip3 install web3 """ import web3 import math import requests headers = { 'content-type': 'application/json', 'accept-encoding': 'gzip, deflate, br', 'user-agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/107.0.0.0 Safari/537.36', } class Rpc: """ eth rpc方法 """ def __init__(self, rpc='https://rpc.ankr.com/eth_goerli', chainid=5, proxies=None, timeout=30): self.rpc = rpc self.chainid = chainid self.proxies = proxies self.timeout = timeout def get_transaction(self, txhash): """获取的交易详情""" data = {"jsonrpc":"2.0","method":"eth_getTransactionByHash","params":[txhash],"id":1} res = requests.post(self.rpc, json=data, headers=headers, proxies=self.proxies, timeout=self.timeout) return res.json() def get_gas_price(self): """获取gas""" data = {"jsonrpc":"2.0","method":"eth_gasPrice","params":[],"id":1} res = requests.post(self.rpc, json=data, headers=headers, proxies=self.proxies, timeout=self.timeout) return res.json() def get_balance(self, address): """获取余额""" data = {"jsonrpc":"2.0","method":"eth_getBalance","params":[address, 'latest'],"id":1} res = requests.post(self.rpc, json=data, headers=headers, proxies=self.proxies, timeout=self.timeout) return res.json() def get_transaction_count_by_address(self, address): """获取地址nonce""" data = {"jsonrpc":"2.0","method":"eth_getTransactionCount","params":[address,'latest'],"id":1} res = requests.post(self.rpc, json=data, headers=headers, proxies=self.proxies, timeout=self.timeout) return res.json() def send_raw_transaction(self, hex): """广播交易""" data = {"jsonrpc":"2.0","method":"eth_sendRawTransaction","params":[hex],"id":1} res = requests.post(self.rpc, json=data, headers=headers, proxies=self.proxies, timeout=self.timeout) return res.json() def transfer(self, account, to, amount, gaslimit, **kw): """离线交易 account to: 收款地址 gaslimit: 由当前区块的gaslimit获取 gasprice: get_gas_price获取 nonce: 交易总数 get_transaction_count_by_address获取 chainId: 链id """ amount = int(amount, 16) if isinstance(amount, str) else int(amount) gaslimit = int(gaslimit, 16) if not isinstance(gaslimit, int) else gaslimit gasprice = int(self.get_gas_price()['result'], 16) nonce = int(self.get_transaction_count_by_address(account.address)['result'], 16) tx = {'from': account.address, 'value': amount,'to': to, 'gas': gaslimit, 'gasPrice': gasprice, 'nonce': nonce, 'chainId': self.chainid} if kw: tx.update(**kw) signed = account.signTransaction(tx) return self.send_raw_transaction(signed.rawTransaction.hex()) if __name__ == '__main__': privkey = 'xxxxxxxx' # 这里替换成自己的私钥 account = web3.Account.from_key(privkey) rpc = Rpc() value = 0.01 # 要存款的数量 gaslimit = 100000 # gaslimit base_token = '0xe93c8cd0d409341205a592f8c4ac1a5fe5585cfa' # base存款的合约地址 method = '0xe9e05c42' # 存款方法hash值 addr_0 = account.address[2:].rjust(64,'0') # 地址格式处理 amount = int(value * math.pow(10, 18)) # eth的主币精度是18位 value = hex(amount) # value hex格式处理 unit_1 = value[2:].rjust(64,'0') unit_2 = hex(int(gaslimit))[2:].rjust(64,'0') bool_3 = '0000000000000000000000000000000000000000000000000000000000000000' unit_4 = '00000000000000000000000000000000000000000000000000000000000000a0' unit_5 = '0000000000000000000000000000000000000000000000000000000000000000' data = method + addr_0 + unit_1 + unit_2 + bool_3 + unit_4 + unit_5 # 拼接数据 res = rpc.transfer(account, to=base_token, amount=amount, gaslimit=gaslimit, data=data) # 发送交易 print(res) # 打印交易hash 6、一旦交易完成，您将在您的 Coinbase 账户中看到您的存款。请注意，存款可能需要一段时间才能在 L2 Base 上确认并显示。 https://base-goerli.blockscout.com/ 请注意，L2 Base 可能需要一些时间来处理您的存款，因此请耐心等待。如果您在存款过程中遇到任何问题，请与 Coinbase 支持团队联系。
