OpenEden and Ceffu Launch First Yield-Bearing Collateral on MirrorRSV

Institutional clients can use cUSDO, OpenEden Digital’s yield-bearing digital asset, as collateral on MirrorRSV while retaining trading access on Binance exchange. 15 July 2025, Bermuda— OpenEden , a leading platform for the tokenization of real-world assets (RWAs), today announced its integration with Ceffu’s MirrorRSV. This first-ever collaboration introduces cUSDO as the first yield-bearing digital asset accepted as off-exchange collateral for trading on Binance, enhancing capital efficiency and minimizing counterparty risks for institutional clients. Through this integration, institutions can custodize cUSDO securely in Ceffu’s segregated cold storage within the MirrorRSV platform, with a representative asset (cUSDOX) issued 1:1 by Binance to the clients’ Portfolio Margin accounts for margin trading. The institutional clients’ cUSDO earns daily yield that is generated from its reserve assets, composed of tokenized US Treasury Funds. “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.” This integration demonstrates how compliant, yield-bearing digital assets can enhance capital efficiency for institutions without sacrificing custody safeguards or exchange-level liquidity. By bringing cUSDO to MirrorRSV, OpenEden reinforces its mission to bridge traditional finance and DeFi with compliant, secure, and high-utility tokenized assets. USDO is issued by OpenEden Digital, a Bermuda-licensed and regulated entity. USDO is fully backed by tokenized US Treasuries, including OpenEden’s Moody’s investment-grade rated TBILL Fund. cUSDO, the wrapped version of USDO, is compliant with the ERC-4626 standard and accrues yield through token price appreciation, making it highly composable and ideal for integration across DeFi and institutional platforms alike. — About OpenEden OpenEden operates a leading real-world asset (RWA) tokenization platform, renowned for its unmatched focus on regulatory standards and advanced financial technology.
