New York City, US - On April 10, Cosmos launches a new bridge product, IBC Eureka, that delivers fast and affordable 1-click connections between Ethereum and Cosmos chains. Networks and protocols using IBC Eureka include Babylon Genesis blockchain utilizing the Bitcoin staking protocol developed by Babylon Labs, Bitcoin LST and DeFi partners Lombard, Lorenzo, PumpBTC, SatLayer, and Tower DEX, ZK proving network ZkCloud, data services provider SEDA Protocol, DeFi provider Elys Network, and leading DeFi blockchain Injective. Other chains adding IBC Eureka to their interoperability suite include dYdX and MANTRA.
Eureka unlocks true multichain experiences across ecosystems. Today’s reliance on bridges causes liquidity and user fragmentation and introduces third-party intermediaries. IBC Eureka removes these barriers with seamless, secure, and expressive connectivity, enabling developers to build multichain applications that function across ecosystems, similar to how APIs are used in web2. Using the Cosmos Hub as a routing layer, chains that use Eureka unlock access to all users, liquidity, and services on the multichain over 1 IBC connection – creating a distribution zone upon which multichain applications can be built.
The team behind IBC Eureka is Interchain Labs, the development and growth arm of the Interchain Foundation and Cosmos ecosystem. In its first iteration, the solution provides fast, affordable, and secure transfers from Ethereum to all Cosmos chains. It does so by combining v2 of the Inter-Blockchain Communication Protocol for its light-client-backed interoperability, the Skip:Go application and API for bridge aggregation and intents, and the Cosmos Hub to provide the IBC routing, without the need for added connections.
Experiences enabled for the Cosmos and Ethereum communities at launch include:
-
Babylon community will be able to move their Bitcoin liquid staking tokens (LSTs) from Ethereum to Babylon’s Cosmos chain with ease, opening up access to native DeFi for Bitcoin users.
-
Tower DEX will enable users to bridge multiple tokens to be traded on its new Tower.fi DEX, which will launch on Babylon Genesis.
-
Lombard, issuer of Bitcoin LST LBTC, will enable users to seamlessly transfer $LBTC between Ethereum and Babylon Genesis.
-
SEDA, the oracle network, will enable users to transfer $SEDA assets from the SEDA Network to Ethereum with Eureka.
-
MANTRA, a leading RWA platform, will soon leverage IBC Eureka to bridge institutional capital from Ethereum into Cosmos-based real estate markets, staking infrastructure, and permissioned DeFi applications.
-
dYdX, the largest decentralised derivatives exchange by volume, is integrating IBC Eureka in an upcoming release to enable institutional Ethereum liquidity to flow seamlessly into its Cosmos-based trading platform.
IBC Eureka enables transfers from Ethereum for less than $1, including gas and relay fees, in seconds, and ERC-20s will be available for one-click transfers into Cosmos. Protocols that use IBC Eureka will also get day-1 distribution to over 50 wallets and frontends.
Ethereum is the first non-Cosmos chain to be added to IBC Eureka. Soon, Solana, Base, Arbitrum and other chains will be added for seamless 1-click transfers. Furthermore, the team expects to incubate the first cohort of Eureka-specialized ecosystem products, starting with an Eureka-powered DeFi product on the Cosmos Hub.
Barry Plunkett, Co-CEO of Interchain Labs, said: “IBC Eureka represents a steep improvement in security and programmability for cross-chain communication. It will allow developers across Ethereum and Cosmos to build a new class of applications that unify and compose the liquidity and protocols historically fragmented across multiple chains. Our mission for 2025 is to continue to expand IBC Eureka, onboarding additional chains to create a truly unified Interchain economy.”
Fisher Yu, CTO of Babylon Labs, said: “The capability to bring Bitcoin Staking LSTs minted on Babylon Genesis into Cosmos over IBC Eureka marks a major step toward unlocking Bitcoin’s full DeFi potential. This integration enables seamless, secure, and efficient access to Cosmos DeFi for Bitcoin holders - and brings us closer to Bitcoin alignment across every chain and the broader ecosystem.”
