#### 2. Get Dojang, Test Tokens, and Upbit Web3 Names

{% hint style="info" %}
**Dojang** is a service that issues off-chain information as on-chain attestations. For more details, see the [Dojang](https://docs.giwa.io/giwa-chain/en/giwa-ecosystem/dojang) documentation. You can revoke issued Dojang by clicking the **Revoke Dojang** button.

**Test tokens** can be claimed every 24 hours.

**Upbit Web3 Names** is a username that can be used in the format `username.up.id` instead of wallet addresses like `0x1234..`. For more details, see the [Upbit Web3 Names](https://docs.giwa.io/giwa-chain/en/giwa-ecosystem/up-id) documentation.

Attester and contract addresses can be found in [Dojang Contracts](https://docs.giwa.io/giwa-chain/en/giwa-ecosystem/dojang/contracts) and [GIWA Contracts](https://docs.giwa.io/giwa-chain/en/network-information/contracts).
{% endhint %}

{% hint style="warning" %}
**Upbit Web3 Names Change Policy**

Upbit Web3 Names cannot be changed by default. However, you can set a new name only if someone else has taken your name after 30 days have passed since you revoked your Dojang.

For example, Alice was using `alice.up.id` and then revoked her Dojang. After 30 days, if Bob took `alice.up.id`, Alice must set a new name when she issues Dojang again. If no one took it, Alice can continue using her existing `alice.up.id`.
{% endhint %}

After connecting your wallet, click the buttons in order: **Issue Dojang** → **Claim VerifiedToken** → **Issue UP ID** to issue each one. Each step requires sending a transaction, which consumes gas fees. If you don't have test ETH, you can get some from [Claim Test ETH](https://docs.giwa.io/giwa-chain/en/get-started/faucets).
