Important Upgrade: Rhino Revamp & Claiming StarkEx Funds

StarkEx fund claim update – 18 December 2025

Users have been able to claim funds from legacy.rhino.fi since 1 March 2025. While many users have successfully withdrawn their assets, there are still unclaimed balances remaining in the legacy StarkEx system.

This notice applies to any users with unclaimed balances:

• Until 1 March 2026, users can continue to access and claim their funds at any time using the existing process by visiting: legacy.rhino.fi

• From 1 March 2026, any remaining unclaimed funds will be moved and securely held by an authorised third-party entity. Your funds will remain available to you, subject to applicable and reasonable expenses. Moving unclaimed balances into a specialised entity ensures appropriate segregation of funds and dedicated oversight of their management.

We are committed to ensuring that all funds remain appropriately safeguarded and effectively administered while we continue efforts to reconnect users with their assets.

If you have any questions or experience issues when claiming your funds, please contact our support team via app.rhino.fi .

We’re excited to share that rhino is moving to the next level. We've been busy working to improve our tech stack and retiring the current Layer 2 StarkEx system to make way for Rhino Revamp—our most powerful upgrade yet, improving the speed and user experience of rhino.fi bridge and laying the ground work for future improvements.

Our StarkEx Journey

We launched the first-ever Layer 2 on StarkEx in 2020, pioneering technology from Starkware, which enabled us to offer reduced fees and lightning-fast speeds for our orderbook DEX (back when we were DeversiFi). DeFi has since grown exponentially, and we now have an ecosystem of over 50 L2s, altVMs, and L1s, powering the fastest and most exciting DeFi ecosystem.

Because of these exciting advancements and our focus on abstracted, seamless interoperability, we no longer need our StarkEx engine. Removing it from our bridge paves the way for something even more exciting—the Revamp upgrade.

What’s Changing?

As of 21st January 2025, the following features will no longer be available from within the main rhino.fi app:

• Portfolio management

• Deposits

• Withdrawals

• Swap

• Layer 2 History (Withdrawals, Deposits, Transfers)

Bridging and sending funds between chains will continue to operate as normal!

Action Required:

Please withdraw all funds held on rhino.fi’s Layer 2 before 28th February 2025 to ensure the simplest experience and uninterrupted access to your assets. If you still have funds in the legacy StarkEx system after the 20th of January, you can continue to access your portfolio and withdraw your funds at legacy.rhino.fi until 28th February 2025.

For those who do not withdraw before 28th February, an alternative method for withdrawal will become available after that date.

What Happens Next?

On 21st January 2025, we’ll be pushing the Revamp upgrade live, removing the above features and the need for trading keys - making your experience simpler than ever.

Deposits to StarkEx L2 will no longer be possible after the 20th January.

This iteration is just Phase 1, creating a foundation for exciting improvements like:

• Transactions that are at least 2x faster

• A dramatically improved UX for non-EVM & L1 bridging

• New features including bridge-and-swap

Looking Ahead

Removing StarkEx also opens the doors for new advancements in cross-chain liquidity. We’re looking closely at Polygon’s aggregation layer, Optimism's Superchain, Espresso, and other developments in modular scaling that can take us beyond this and ensure rhino.fi remains at the forefront of DeFi innovation.

We’re paving the way for a bold new future for rhino, and we can’t wait for you to join the ride.
