RealFi Launches Public Testnet for USDr Ahead of Mainnet Rollout

Institutional-grade infrastructure designed to let stablecoin holders the option to stake for yield enters public testing phase

London, UK – 6 July 2026 – RealFi, a stablecoin infrastructure platform focused on connecting on-chain capital with real-world fixed-income markets, today announced the launch of its Public Testnet, marking the next phase in the rollout of USDr, its dollar-pegged stablecoin, and sUSDr, the yield-bearing token that staking unlocks.

The Public Testnet will serve as a live environment for users, developers and institutional participants to test RealFi’s infrastructure ahead of its planned mainnet launch later this year. The release forms part of a broader effort to address what RealFi describes as one of the digital asset sector’s largest inefficiencies: the vast amount of stablecoin capital sitting idle across exchanges, wallets and treasury accounts.

USDr is the protocol’s liquid, non-yield-bearing base stablecoin. Holders who choose to stake USDr receive sUSDr, a separate yield-bearing instrument. Yield accrues to sUSDr from a reserve of real-world financial instruments including money market funds, corporate floating rate bonds and direct lending to fintech, rather than relying on crypto-native token incentives or inflationary emissions models. RealFi is targeting sUSDr yields of up to 9% APY through a reserve-backed structure intended to prioritize sustainability, transparency and capital efficiency. Yields are indicative, variable, and not guaranteed.

The Testnet launch introduces the first public version of RealFi’s infrastructure stack, allowing participants to explore wallet integrations, yield mechanics, staking flows and broader protocol functionality under live market conditions.

“Stablecoins have become one of the most important pieces of infrastructure in digital finance, but most of the capital sitting inside them remains economically unproductive,” said John O’Connor, CEO of RealFi. “The next stage of the market is not simply putting dollars on-chain. It is creating infrastructure that allows those assets to participate in real economic activity while maintaining the liquidity and accessibility users expect from stablecoins.”

The launch comes as institutional interest in tokenized real-world assets and yield-bearing stablecoin models continues to accelerate globally. According to RealFi, the market is increasingly moving beyond speculative yield structures toward models backed by traditional financial instruments and verifiable cash flows.

Launching on Cardano and then Ethereum very shortly afterwards, RealFi’s infrastructure combines reserve-backed yield generation with Cardano-native staking mechanics and a stability-focused architecture intended to reduce dependence on volatile DeFi market conditions.

The Public Testnet is also intended to act as a large-scale infrastructure and market stress test ahead of RealFi’s anticipated mainnet rollout, with feedback from users and partners expected to inform the next phase of deployment.

“We believe the future of stablecoins will look far closer to financial infrastructure than speculative crypto products,” O’Connor added. “The long-term opportunity is building systems where digital dollars are not just stable, but productive.”

The Testnet launch follows growing institutional attention toward tokenization, on-chain fixed-income products and stablecoin-based settlement infrastructure as financial markets continue exploring blockchain-enabled capital markets.
