How do cross-chain bridges work on Ergo?

Ergo bridges use a combination of multi-signature wallets, oracle pools, and smart contracts to lock assets on one chain and mint wrapped versions on another. Validators ensure the integrity of cross-chain transactions.

What is Rosen Bridge?

Rosen Bridge is Ergo's flagship decentralized bridge solution. It uses a network of watchers and guards to facilitate trustless asset transfers between Ergo and other blockchains without central points of failure.

Are bridged assets secure?

Yes, bridged assets are secured through multi-signature contracts and decentralized validator networks. The original assets are locked in secure contracts, and wrapped versions maintain 1:1 backing.

Which chains can Ergo connect to?

Ergo can connect to any blockchain that supports multi-signature wallets or smart contracts. Current bridges support Cardano, Bitcoin, and Ethereum, with more chains being added regularly.

How long do bridge transfers take?

Transfer times vary by destination chain. Typically, transfers complete within 10-30 minutes, depending on network congestion and confirmation requirements on both chains.
