Cosmos has unveiled Eureka, a new interoperability layer designed to connect its inter-blockchain communication (IBC) protocol with Ethereum. Announced on April 10, Eureka transforms IBC from an ecosystem standard into a universal interoperability protocol, paving the way for multichain apps. This move allows Cosmos-based applications to reach more users by integrating with Ethereum. Unlike traditional bridges that fragment users and liquidity, Eureka promises native interoperability, enabling seamless asset movement across blockchains. Early adopters include Bitcoin staking protocol Babylon and DeFi platform Elys. More integrations, like with DEX dYdX, are anticipated.
