Tether Gold (XAUT) Asset Information

Asset name: Tether Gold

Asset description: Tether Gold is a product that combines the advantages of physical assets and virtual assets, designed to allow holders to own gold in the form of a virtual asset. Tether Gold grants 1:1 ownership for one troy ounce (approximately 31.1g) of gold bullion that meets the London Bullion Market Association (LBMA) Good Delivery standard per 1 XAUT. This allows investors to stably hold the value of gold while avoiding issues such as storage costs, transportation risks, and accessibility constraints that arise when directly storing physical gold.

Notes

• Information regarding supported virtual asset listings and trading support services that are scheduled to be updated will be updated prior to the start of trading support, so please check.

• Scheduled supported virtual assets may have their trading support start delayed or canceled due to circumstances on the issuer's side or Coinone's trading support criteria.

• Under the Act on the Protection of Virtual Asset Users, unfair trading practices (such as use of undisclosed material information) are prohibited, so we ask for users' cooperation to maintain a sound market order for virtual asset trading.

• For newly supported virtual assets, only limit sell orders are allowed for the first 5 minutes from the sell open time.

• If a deposit is made from a virtual asset service provider not included in the Travel Rule solution integration list, it may take a long time until the return is processed.

• Before depositing virtual assets, please be sure to check the supported network and whether a memo or secondary address is required to avoid incorrect deposits.

• In the event of an incorrect deposit of virtual assets, you may request the return of the virtual assets according to Coinone Customer Center's incorrect deposit return guide.

• Coinone provides the whitepaper, key information summary, explanatory documents, community links, etc., for virtual assets approved for trading support and strives to periodically review and update them.

⁃ Coinone does not provide any investment recommendations related to virtual asset trading.

⁃ Virtual assets are high-risk products and may result in partial or total loss of invested funds.

⁃ When trading virtual assets, please be sure to consider the risk of principal loss due to price fluctuations.

⁃ For safe trading, we recommend that you first review explanatory materials such as the whitepaper and related terms for the relevant virtual asset when trading virtual assets.
