BitGo 的ETH是采用智能合约方式，不需要归集地址。 BitGo最近更新了合约 关键代码如下，增加了批量发送 批量发送给需要的地址，没有发送出去的送回去。

 function batch(address[] calldata recipients, uint256[] calldata values) external payable lockCall {
        require(recipients.length != 0, "Must send to at least one person");
        require(recipients.length == values.length, "Unequal recipients and values");
        require(recipients.length < 256, "Too many recipients");

        // Try to send all given amounts to all given recipients
        // Revert everything if any transfer fails
        for (uint8 i = 0; i < recipients.length; i++) {
            require(recipients[i] != address(0), "Invalid recipient address");
            (bool success,) = recipients[i].call{value: values[i], gas: transferGasLimit}("");
            require(success, "Send failed");
            emit BatchTransfer(msg.sender, recipients[i], values[i]);
        }

        if (address(this).balance > 0) {
            (bool success,) = msg.sender.call{value: address(this).balance, gas: transferGasLimit}("");
            require(success, "Sender refund failed");
        }
