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）。

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。
