Financial Services
Describe your established collaborations.
Key collaborations include:
PALM Economy ($PALM): A standout example of Rosen's impact on Cardano projects. Rosen has facilitated the cross-chain transfer of over 3.5 billion $PALM tokens between Cardano and BNB Chain.
Established Bridges:
Bitcoin (rsBTC): Live since mid-2024, enabling Bitcoin liquidity on Cardano and Ergo for DeFi applications.
Ethereum and EVM Chains: Integrated in late 2024,
BNB Chain: Added in early 2025,
Dogecoin ($DOGE): Fully launched in July 2025
Describe funding commitments.
Rosen Bridge: No VC Backing
Rosen Bridge operates without venture capital (VC) backing, distinguishing it from many blockchain projects that rely on institutional investors for initial funding. Instead, it bootstraps through community-driven mechanisms, token allocations, and protocol-generated revenues.
Describe your key performance metrics.
Total Value Locked (TVL): $9.13 million, indicating the total assets secured in the bridge.
Supported Chains and Assets: Currently 6 chains (Cardano, Ergo, Bitcoin, Ethereum, BNB Chain, Dogecoin)
Collaborations include Hummingbot for liquidity management, and rsAsset support for 20+ tokens
Community and Development Metrics
Please describe your proposed solution and how it addresses the problem
Exchange listings have intense capital requirements that pull value from projects directly. This requires a project either sell tokens on the market, having the community funding indirectly fund listings, or by governance requests. This practice does not scale. The second large capital expense is related to market making.
Rosen has been specifically designed to address these barriers. The implementation will allow any CNT to move across major exchange environments and have support for open source market making tools. This accesses new users, new liquidity, and broadens the reach of Cardano Projects without the cost burdens of listings.
It is more censorship resistant, does not come with liquidity requirements and improves the long term position of the Cardano ecosystem, as currently the external market access for CNTs is extremely limited.
Please define the positive impact your project will have on the wider Cardano community
Rosen Bridge already supports multiple CNT's and has never charged for listing support.
Any token holder can contact the Rosen Bridge team and petition us to support new CNT's across environments. It is a point of open access that is provided to the Cardano community based on previous catalyst grants.
This toolset is open source, and designed to address market frictions that occur in the crypto space. We have multiple infrastructure system service providers for Rosen in the Cardano community running stake pools.
We are working to align incentives with external development to drive external assets into the Cardano DeFi markets in parrallel.
Opening Solana to CNT's allows projets to focus less on access costs and more on software and community development.
What is your capability to deliver your project with high levels of trust and accountability? How do you intend to validate if your approach is feasible?
We have delivered on previous Catalyst proposals, and have created a clear open contribution standard for Rosen bridge that concisely lays out the tools, and tests needed for new chains.

Milestone Title
Rosen Chain Support
Milestone Outputs
The Rosen-chains packages contain the most functionalities of the new blockchain and mainly is used in the Guard Service.
For the sake of simplicity, the implementation is divided into four parts and it is highly recommended to implement them in the following order:
Abstract Chain (Bases)
Rosen Extractor (Universal)
Abstract Chain
Abstract Chain Network
Acceptance Criteria
Rosen Chain Packages will be built for Solana.
These components will be open source and available for review on our github

Milestone Title
Rosen Health Check
Milestone Outputs
Health Check
As the name suggests, these packages check the healthiness of some components in both Watcher and Guard services. For new blockchains, two parameters are required.
Asset Check
This health check parameter monitors the balance of specified assets at given addresses, primarily used by the Guard service to ensure sufficient native token to pay bridge transaction fees.
Scanner Sync Check
This parameter checks the last scanned block with the current block of the network and is mainly used in the Watcher service.
Acceptance Criteria
The Rosen Bridge team will build and release the Asset check and Scanner sync modules for Solana according to Contribution Standards guidelines.
These will be open source available for review on github.

Milestone Title
Module IntregrationMilestone Outputs
Milestone Outputs
After implementing the required modules, they can be integrated into the main services. Unlike module implementation, the order does not matter in the integration phase, and the chain can be deployed once its modules are integrated into the four services:
Watcher Service
Guard Service
Rosen App
Contracts
Acceptance Criteria
Rosen team will update its github demonstrating the integration of the existing modules for Solana into the following:
Watcher Service
Guard Service
Rosen App
Contracts
This will folllow the Rosen Contribution Standard.
This will be open and available for review.

How does the cost of the project represent value for the Cardano ecosystem?
Rosen Bridge opens access to 2 exchange environments for all CNT's for much less that the listing cost of one CNT project to get listed on an exchange.
The cost of market access does not scale well across ecosystems as in most cases projects are selling tokens to fund listing costs.
