USDS (USDS) Asset Information

Asset Name: USDS

Asset Introduction: USDS (USDS) is a dollar-pegged stablecoin upgraded by Sky, inheriting the philosophy of DAI. It was launched as the successor asset to the existing stablecoin DAI through the rebranding by MakerDAO, and is currently operated with a structure that allows a 1:1 conversion with DAI. DAI is issued with various assets such as ETH, USDC, and RWA (real-world assets) as collateral, and USDS follows an indirect collateral structure based on these assets. In the future, it will be expanded to directly utilize a wide range of assets as collateral through Sky's own Vault system, and USDS is designed to function as a store of value, means of payment, and for deposit utility.

Precautions

• For 5 minutes after the start of trading support, only limit sell orders are available.

• If virtual assets are deposited from a virtual asset service provider not included on the Travel Rule solution list, refunds may take a significant amount of time.

• Please confirm whether the supported network and additional address info (e.g., memo, secondary address) are required, to prevent incorrect deposits.

• In case of incorrect deposit, you may request a return of virtual assets following Coinone Customer Center's guide for deposit returns.
