Noble Blockchain has launched its interest-bearing stablecoin USDN within the Cosmos ecosystem. This stablecoin offers an annual yield of approximately 4.15%, with returns adjusted based on its treasury collateral. USDN will initially be supported in the Keplr wallet and can be purchased using a credit card through Moonpay. USDN is built using the M^0's $M protocol, which is a new customizable stablecoin framework. Noble has also introduced a "points" activity, allowing users to earn income through two methods: staking USDN and using a flexible treasury. The staking treasury allows depositors to lock USDN for up to four months, forfeiting yields to accumulate points, while the flexible treasury provides "enhanced" yields paid by the forfeited returns.
