Ceffu and exSat Enable Secure Bitcoin Yield for Institutions Through MirrorRSV IntegrationCeffu and exSat enable secure Bitcoin yield for institutions through MirrorRSV integration
Ceffu is pleased to introduce our MirrorRSV integration with exSat—marking its first institutional deployment—providing a secure way to generate Bitcoin yield while maintaining institutional-grade custody. MirrorRSV, Ceffu’s flagship off-exchange settlement solution, allows institutions to access Binance’s liquidity while assets remain securely held in verifiable cold storage. By mirroring assets 1:1 to Binance without physical transfers, it eliminates counterparty risk while maintaining full capital efficiency. This integration extends MirrorRSV’s capabilities to exSat’s Bitcoin-native ecosystem for the first time.
This partnership brings together Ceffu's institutional custody expertise as Binance's exclusive partner and exSat's Bitcoin-native financial infrastructure. The result is a seamless framework that bridges centralized and decentralized finance while maintaining compliance - with MirrorRSV serving as the secure gateway. Institutions now gain three key benefits:
Secure Binance liquidity access
Through MirrorRSV, institutions gain 1:1 access to Binance Exchange liquidity while assets remain protected in Ceffu’s institutional-grade cold storage. This approach uniquely preserves custody security – assets stay in verifiable on-chain addresses without commingling – while delivering the full trading efficiency of Binance’s Portfolio Margin system.
Transparent CeDeFi operations
For institutions prioritizing transparency, this integration establishes a meaningful standard: exSat-side yield activities and Binance withdrawals are settled on-chain with immutable verification. While exchange execution remains off-chain, this balanced approach delivers verified custody through on-demand proof of reserves, documented transactions with permanent on-chain records, enhanced visibility beyond traditional cold storage, and reduced opacity between CeFi and DeFi environments.
Hybrid yield strategies
As MirrorRSV’s first Bitcoin protocol integration, the solution unlocks new institutional-grade yield opportunities. Clients can simultaneously:
Earn through Binance’s centralized products
Participate in exSat’s decentralized strategies (staking/RWAs)
Execute delta-neutral trades with custody protections
Yves La Rose, Founder of exSat, captures the partnership’s transformative potential: "With Ceffu’s MirrorRSV integration, we’re realizing a critical milestone – seamlessly connecting institutional finance to Bitcoin’s yield ecosystem while preserving the governance standards of traditional markets." The solution marries institutional requirements with blockchain-native innovation, enabling ompliant capital deployment at scale.
Ian Loh, CEO of Ceffu, underscores the infrastructure imperative: "As Bitcoin evolves from store-of-value to yield-bearing asset, institutions demand custodial security that never lags behind financial innovation. Our work with exSat delivers precisely this – a framework where security and yield generation advance in lockstep."
Looking ahead
This partnership delivers tangible benefits for institutional participants: the ability to maintain Ceffu’s institutional custody standards while accessing exSat’s yield opportunities, all through a single streamlined integration. Looking ahead, we see this as the first of many practical steps to make Bitcoin more productive for institutional portfolios.
