FAQs: Rosen Bridge Operations and Features

What is the bridge fee structure?

Initially, it's the greater of $10 or 0.5% of the transaction value, plus network fees, adjustable by the guard set. The fee is collected in the transferred token on Ergo. Network fees vary: static for Ergo and Cardano, dynamic for EVM-based networks.

Is there a maximum amount for a single transaction on Rosen Bridge?

No fixed maximum, but large transfers may take longer, from hours to 1-2 days, due to manual guard intervention for fund transfers from cold to hot wallets.

How is ADA managed within the system for transactions to Cardano?

Network fees in the transaction token on Ergo are sent to a dedicated address for covering network fees on different chains. Currently, the Rosen team manually manages this, with plans for future automation.

How can a project add new token options to the bridge?

Projects pay a listing fee to the Rosen Fund, with potential discounts for open-source projects. This involves minting wrapped tokens and updating the token map. Fees are distributed to watchers and guards.

What are the next chains to be added following ADA?

The roadmap includes BTC, BSC (EVM-chains), and Dogecoin in the midterm. Code refactoring aims to facilitate adding new chains, with initial chains being the most challenging.

What is the size and composition of the team?

The team includes 8 developers, with some frontend and UI tasks outsourced. Additionally, 2-3 developers have worked part-time over the past year, supported by several advisors.
