Ceffu integrates with OpenEden to enable yield-bearing digital assets as collateral on MirrorRSV

2025-07-15  •  3 min read

Ceffu is excited to announce our integration with OpenEden, bringing the first yield-bearing digital asset as collateral on MirrorRSV. This partnership addresses institutional demand for capital-efficient solutions while maintaining the security and compliance standards our clients expect.

Unlocking Yield-Bearing Collateral

MirrorRSV, Ceffu's latest off-exchange settlement solution, enables institutions to access our partner exchange’s deep liquidity while keeping assets securely stored in verifiable cold storage. With the OpenEden integration, institutional clients can now earn yield on their collateral through cUSDO while maintaining full trading capabilities.

About OpenEden and USDO

Founded in 2022, OpenEden operates a leading real-world asset (RWA) tokenization platform with a core focus on compliance and transparency. In early 2025, OpenEden launched USDO, a regulated, yield-bearing stablecoin that is:

  • Pegged 1:1 to the US dollar

  • Fully backed by tokenized US Treasuries

  • Issued through OpenEden Digital Limited, a licensed Bermuda entity

For enhanced composability in DeFi and institutional platforms, USDO can be wrapped into cUSDO, an ERC4626-compliant token that accrues yield through daily price appreciation.

How It Works

Clients can use OpenEden's cUSDO as collateral on MirrorRSV while earning yield from the underlying reserve assets. cUSDO's value increases daily, reflecting returns generated from a diversified basket of tokenized Treasury products including but not limited to $TBILL, $BUIDL and $VBILL. 

The collateral asset is secured in a segregated cold storage wallet, with clients receiving a representative asset (cUSDOX) at a 1:1 ratio in their Binance Portfolio Margin account. 
OpenEden's commitment to compliance and transparency is evident in USDO's structure:

  • Licensing and oversight: USDO is issued through OpenEden Digital Limited, operating under a Digital Asset Business license from the Bermuda Monetary Authority (BMA). The issuer is structured as a bankruptcy-remote Segregated Account Company (SAC), providing legal protections for token holders.

  • Dual verification: USDO employs both on-chain and off-chain verification:

  • On-chain: Chainlink's Proof of Reserve provides real-time visibility into reserve assets

  • Off-chain: Independent third-party fund administrators publish Net Asset Value (NAV) reports

This comprehensive approach ensures transparency while supporting integration across both DeFi and institutional ecosystems.

"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."

"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."

Looking Ahead

This partnership represents a significant step in bridging traditional finance with Web3, enabling clients to access yields from traditional finance while trading securely on the world's leading crypto exchange. At Ceffu, we remain committed to building innovative solutions that unlock the full utility of real-world assets.
