OpenEden, a firm focused on real-world asset (RWA) tokenization, has announced the integration of its yield-bearing token cUSDO with Ceffu’s MirrorRSV platform. The collaboration enables institutional clients to use cUSDO as off-exchange collateral for margin trading on Binance while maintaining segregated custody through Ceffu.
The development introduces the first instance of yield-bearing collateral being accepted on MirrorRSV, which facilitates off-exchange settlement and margin trading.
Yield-Bearing Collateral
The integration allows institutional clients to deposit cUSDO into Ceffu’s cold storage via MirrorRSV. A corresponding asset, cUSDOX, is issued by Binance to the client’s Portfolio Margin account in a 1:1 ratio, enabling trading activity without direct on-exchange asset exposure.
The underlying cUSDO continues to accrue yield while held in custody. That yield is derived from reserve assets comprising tokenized U.S. Treasury Funds, including OpenEden’s TBILL Fund, which has received a Moody’s investment-grade rating.
“OpenEden’s partnership with Ceffu delivers a much sought-after innovation to institutional trading,” said Jeremy Ng, Founder of OpenEden. “With cUSDO as the first yield-bearing collateral on MirrorRSV, institutions can earn yield on collateral assets held in off-exchange custody while retaining full margin trading access on the exchange. This structure mirrors traditional financial markets and is designed to accelerate institutional participation in digital asset investments.”
“The integration of yield-bearing collateral represents a fundamental shift in how institutions can optimize their digital asset strategies,” said Ian Loh, CEO of Ceffu. “Together with OpenEden, we have built a solution that bridges the gap between traditional finance and the digital asset ecosystem. It’s exactly the kind of innovation that will accelerate institutional adoption of digital assets.”
Regulated Yield-Bearing Stablecoin
cUSDO is the wrapped version of USDO, a regulated yield-bearing stablecoin issued by OpenEden Digital, a Bermuda-licensed entity. The token complies with the ERC-4626 standard and is intended to facilitate broader composability across decentralized finance (DeFi) and institutional platforms.
USDO is fully backed by tokenized U.S. Treasuries, and its reserves are transparently disclosed and independently verified.
While yield-bearing stablecoins and tokenized treasuries are not new to DeFi, their integration into institutional trading workflows remains relatively new. But with increased attention on risk management and capital efficiency, this new integration can appeal to institutional trading firms seeking to reduce counterparty risk, and serve as a test case for how yield-generating instruments can operate within compliant, off-exchange frameworks.
