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

Dojang is a service that issues off-chain information as on-chain attestations. For more details, see the 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 documentation.

Attester and contract addresses can be found in Dojang Contracts and GIWA Contracts.

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.

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.
