Institutions need more than just deep liquidity. They need solutions that allow them to better manage risk and further scale their activity. After strong uptake of MirrorX — Ceffu’s flagship off-exchange third-party custody solution launched in 2023 — they’re now introducing the next step in its evolution: MirrorRSV. It offers the same seamless access to Binance, but with assets held in segregated cold wallets, verifiable on chain.

What Is MirrorRSV?

MirrorRSV (pronounced “Mirror Reserve”) is Ceffu’s latest off-exchange settlement solution for VIP and Institutional clients — built for those who need on-chain verifiable cold storage without giving up capital efficiency or access to Binance’s liquidity.

Developed by Ceffu, our preferred institutional custody partner, MirrorRSV allows you to trade on Binance while your assets remain securely held in dedicated cold wallets, with full on-chain transparency at all times.

When a client delegates assets from their cold custodial wallet via MirrorRSV, the digital assets are securely locked and simultaneously, a representative token is credited to their Binance account at a 1:1 ratio. These tokens are recognized as the native asset, enabling seamless trading across Portfolio Margin, Margin, and Futures with preferred strategies and speed. Upon exiting a trading position and settling it, the corresponding representative tokens are debited from the client’s Binance account, after which the client can freely access and withdraw their assets from their cold custodial wallet on Ceffu.

MirrorRSV offers an enhanced custody option for clients who require greater asset segregation, auditability, and compliance support.

Why Use MirrorRSV?

For clients focused on mitigating counterparty risks, prioritizing on-chain transparency, and ensuring dedicated cold storage, MirrorRSV offers a secure and efficient way to access Binance — without compromising on control or compliance readiness. Here’s what it offers:

Cold Storage Security

Your assets stay in Ceffu’s Qualified Wallets — institutional-grade cold storage designed to eliminate single points of failure. Secured by multi-party computation (MPC) and strict access controls, these wallets offer deep-layer protection trusted by some of the most risk-aware clients in the market.

On-Chain Verifiability

Each wallet has its own blockchain address, giving you real-time visibility over your holdings. Whether you’re preparing an audit, meeting internal governance checks, or reassuring investors, you’ll always be able to show exactly where your assets are.

Segregated Custody

Unlike pooled solutions, MirrorRSV gives you a dedicated wallet that belongs exclusively to you. This provides clear, dedicated custody that simplifies oversight and strengthens internal controls. Such transparency delivers a significant operational advantage.

Reduced Counterparty Risk

Keeping assets off-exchange mitigates counterparty risk exposure without sacrificing access. You retain full access to Binance’s deep liquidity, while custody is securely maintained by a third-party custodian. This approach enables you to meet internal risk thresholds while ensuring fast execution.

Full Capital Efficiency

With 1:1 mirrored tokens, your capital stays productive. No delays from on-chain transfers, no waiting to deploy funds. Whether you’re rebalancing, scaling positions, or managing leverage, MirrorRSV keeps your operations fast and frictionless.

Final Thoughts

As institutional needs evolve, so should the custody tools that support them. MirrorRSV expands the off-exchange options available through Binance by offering a cold-storage solution designed for clients who prioritize asset segregation and on-chain transparency.

It complements MirrorX, which continues to serve clients who value broader token access and faster daily settlement. Together, they offer a custody framework that adapts to different risk profiles and operational strategies.

MirrorRSV is ideal for TradFi and crypto-native institutions alike with stricter controls, project teams needing real-time proof-of-assets, and clients with specific regulatory or audit requirements. Whether you’re managing investor funds or upgrading your custody setup, MirrorRSV gives you security, visibility, and control — all without compromising access.
