Rosen Bridge
Decentralized Ergo-Cardano bridge with multi-sig architecture
What is Rosen Bridge?
Rosen Bridge is a decentralized bridge connecting Cardano and Ergo, built with a multi-signature architecture that eliminates single points of failure. It enables asset transfers between Cardano and Ergo's eUTXO ecosystems, strengthening the connection between two of the most technically similar blockchain networks.
Key Features
Cardano ↔ Ergo Bridge
Rosen Bridge specializes in the Cardano-Ergo corridor, two UTXO-based blockchains with complementary technologies and overlapping developer communities.
Multi-Sig Architecture
Transfers are secured by a decentralized network of watchers and guards using multi-signature cryptography — no single entity controls the bridge funds.
Decentralized Watchers
Community members can run watcher nodes to participate in bridge security and earn RSN token rewards for honest participation.
RSN Token
RSN is Rosen Bridge's native token used to incentivize watchers and guards who secure the bridge infrastructure.

Frequently Asked Questions
Why bridge between Cardano and Ergo?
Cardano and Ergo share the eUTXO model and overlapping developer communities. Bridging enables cross-ecosystem DeFi, shared liquidity, and access to unique protocols on each chain.
What is the Rosen watcher network?
Watchers are community-run nodes that monitor both chains and verify bridge transactions. They earn RSN tokens for honest participation and are financially penalized for fraud.
Is Rosen Bridge decentralized?
Yes. Rosen Bridge uses a decentralized multi-sig network of watchers and guards rather than a centralized custodian, distributing trust across many independent operators.
What assets can be bridged via Rosen?
Rosen currently focuses on ADA, ERG, and assets native to each chain. Check rosen.tech for the current list of supported assets.
