Rosen Bridge
The future of cross-chain asset transfers. Open-source protocol for secure, efficient, and decentralized bridging between Ergo and other blockchains.
Rosen Bridge leverages Ergo's capabilities to facilitate secure and efficient coin and token transfers between Ergo and other blockchains, eliminating the need for smart contracts on other chains.
Rosen Bridge is expected to launch imminently. Join the Rosen Telegram chat to stay updated with the latest developments and announcements.
Architecture
Rosen Bridge uses a unique architecture with Watchers and Guards. Watchers monitor blockchain activities and report to Guards, who process events and execute actions.
- Watchers monitor blockchain activities
- Guards process events and execute actions
- High security and functionality
No Smart Contracts
One of the unique aspects is that it eliminates the need for deploying smart contracts on other chains. Consensus is achieved on Ergo by Guards.
- No smart contracts on other chains
- Ergo-centric consensus
- Simplified cross-chain operations
Bridge Applications
Token Transfers
Seamlessly transfer coins and tokens between Ergo and any other compatible blockchain.
- • Cross-chain compatibility
- • Multi-signature support
- • Threshold signatures
Scalable Design
Allows addition of new chains through independent modules while prioritizing user transaction success.
- • Independent modules
- • Sufficient confirmations
- • User safety priority
RSN Token
The Rosen Token (RSN) serves as sybil resistance mechanism, fee distribution system, and access control.
- • Sybil resistance
- • Fee distribution
- • Access control

Bridge Operations
Understanding how Rosen Bridge operates and its key operational features.
Fee Structure
The bridge fee structure is designed to incentivize watchers and prevent spam transactions.
Initial Fee: Greater of $10 or 0.5% of transaction value, plus network fees.
Collection: Fees collected in transferred token on Ergo.
Network Fees: Static for Ergo/Cardano, dynamic for EVM networks.
Transaction Limits
Transaction limits and processing times are designed to ensure security and reliability.
No Fixed Maximum: Large transfers may take hours to 1-2 days due to manual guard intervention.
Cold to Hot Wallets: Manual guard intervention for fund transfers between wallet types.
