With Eureka, Cosmos aims to eliminate the limitations of conventional blockchain bridges

Cosmos has launched Eureka, a new interoperability protocol designed to connect Ethereum with the Inter-Blockchain Communication (IBC) protocol.

This development aims to make Cosmos-based blockchains and apps more accessible to Ethereum users while enabling multichain development with greater privacy and liquidity flexibility.

Background

On April 10, Cosmos announced the launch of IBC Eureka—a major upgrade designed to bridge Ethereum and Cosmos ecosystems.
Eureka is positioned as the next evolution of the IBC protocol, which has already facilitated over $3 billion in monthly transaction volume across 115+ blockchains.
This launch marks Cosmos’ transition from being an ecosystem standard to a universal interoperability hub for multichain applications.
With Eureka, Cosmos aims to eliminate the limitations of conventional blockchain bridges, which often cause liquidity fragmentation and require trust in intermediaries.

Why should you pay attention?

Eureka fundamentally alters how blockchains interact, offering native, light-client-based connections to Ethereum with enhanced security and reduced infrastructure overhead.
By creating a single access point through the Cosmos Hub, the new protocol can simplify the integration of multichain services, from DeFi and tokenized assets to real-world applications like Bitcoin staking and institutional finance. It’s a significant step toward realizing a true multichain Web3 environment.

Who said what?

The Cosmos development team stated:

“IBC Eureka makes hundreds of Cosmos apps and chains more accessible through fast and secure asset transfers between Cosmos and Ethereum.”

Highlighting Eureka's impact, the team added:

“It’s more than a product launch. It marks the first step in IBC evolving from an ecosystem-standard to a universal interoperability protocol.”

Developers have praised Eureka’s ability to let applications “leverage the best of any chain with a high-security, protocol-native connection.”
Notable projects such as Babylon, Elys, dYdX, Mantra, and Injective are among the first to integrate the new protocol.

Zooming Out

Eureka’s debut arrives at a pivotal moment for Web3, as more protocols seek scalable and secure ways to interconnect ecosystems without relying on bridges.
With the increasing popularity of Ethereum-based applications and the maturing Cosmos ecosystem, Eureka could play a major role in enabling cross-chain liquidity, expanding use cases for tokenized assets, and onboarding a new wave of institutional developers.
As blockchains move toward composability and shared services, Cosmos' bet on IBC Eureka positions it as a key infrastructure provider for the next phase of decentralized innovation.
