RealFi has launched its public testnet for USDr stablecoin and sUSDr staking token ahead of a planned mainnet launch later this year. According to a press release shared with crypto.news, the public testnet provides users, developers and institutional participants with a live environment to test the infrastructure supporting USDr, the protocol's dollar-pegged stablecoin, and sUSDr, the yield-bearing token users receive after staking USDr. The rollout is intended to test wallet integrations, staking flows, yield distribution and other protocol functions under live market conditions before the network goes fully live.
At the center of the platform is USDr, a liquid stablecoin that does not generate yield on its own. Users who stake USDr receive sUSDr, which earns returns from a reserve of traditional financial assets rather than crypto-native incentives. According to RealFi, those reserves include money market funds, corporate floating-rate bonds, and direct lending to fintech companies. The company is targeting yields of up to 9% APY through its reserve-backed structure, while noting that returns remain indicative and variable and are not guaranteed. RealFi added that the design focuses on capital efficiency, transparency and sustainability instead of inflationary token emissions.
RealFi said the protocol will launch first on Cardano before expanding to Ethereum shortly afterwards. The company combines reserve-backed yield generation with Cardano-native staking while using an architecture designed to reduce reliance on volatile decentralised finance market conditions. According to RealFi, feedback collected during the testnet phase will be used to refine the platform before its mainnet launch. The public testnet will also serve as a large-scale infrastructure and market stress test before the planned mainnet rollout.
The launch comes as financial institutions continue exploring tokenized real-world assets and stablecoins backed by income-generating assets. Earlier this month, former Brazil central bank director Tony Volpon introduced BRD, a Brazilian real-pegged stablecoin backed by government bonds that distributes sovereign debt yields to token holders. However, in the U.S., yield-bearing assets have come under scrutiny, with the American Bankers Association arguing that allowing payment stablecoins to pay interest could encourage deposit outflows from community banks and increase funding costs.
