# 设置 .btc 主域名的方法

如 [Oridinals Primary Name Protocol(Solution B)](/docs/ordinals-primary-name-protocol/ordinals-primary-name-protocol-solution-b-draft.md) 所述, 将你的.btc 域名转给你自己，就可以设置好你的主域名。

## 步骤1. 将一个.btc 域名做一次自转操作

1.1 以 UniSat 钱包为例， 选择一个你的 .btc 域名，点击按钮“Send”。

1.2 在Recipient 区域输入你的.btc 或者你自己的钱包地址, 点击 "Next" 按钮。请确保Recipient处填写的地址和你选择的.btc 域名所属的钱包是同一个地址。

等待链上确认。

## 步骤 2. 登录 bdid.io 检查你的主域名

当步骤1的交易在链上确认后，可以打开 <https://bdid.io/marketplace/inscription?namespace=.btc> , 然后点击"Connect Wallet" 按钮。如果你已经登录bdid.io ，可以先登出。

当你链接钱包后，就可以看到你在步骤1设置的主域名。如果还没有显示，可能是因为有一定的延迟，你可以尝试登出再登录。
