The vision for a truly interconnected blockchain ecosystem is no longer theoretical — it's here. With Cosmos, the so-called "Internet of Blockchains," seamless cross-chain communication is now faster, more secure, and easier than ever. At the heart of this evolution is IBC Eureka, the canonical deployment of IBC v2, powered by ATOM, delivering next-generation interoperability across blockchains like Cosmos and Ethereum.
This breakthrough enables chains and decentralized applications (dApps) to connect globally with just one IBC connection, eliminating the complexity and cost traditionally associated with multi-chain infrastructure.
What Is IBC Eureka?
IBC Eureka is not just an upgrade — it’s a reimagining of how blockchains communicate. Built on the latest version of the Inter-Blockchain Communication (IBC) Protocol, IBC v2, it introduces faster-than-finality bridging, meaning assets and data can be transferred across chains in seconds, not minutes.
Powered by the Cosmos Hub, IBC Eureka streamlines routing so that developers and networks gain access to a vast interoperable ecosystem through a single, lightweight connection. No more managing dozens of relayers or bearing the burden of infrastructure costs.

One Connection, Infinite Possibilities
Traditionally, connecting multiple blockchains required setting up individual IBC channels for each pair — a time-consuming and expensive process. IBC Eureka changes that.
With a single connection to the Cosmos Hub, your chain can reach over 50 connected zones across the Cosmos ecosystem and beyond, including Ethereum via optimized bridges. This aggregated routing model drastically reduces overhead while increasing speed and reliability.
Whether you're building a DeFi protocol, a gaming platform, or a Layer 1 blockchain, IBC Eureka provides:
- Fast finality: Transactions confirmed in seconds.
- Near-zero infrastructure cost: No need to run multiple relayers.
- Vendor neutrality: No lock-in to proprietary solutions.
- Full compatibility: Works seamlessly with IBC-go v10, Cosmos SDK v0.50, and CometBFT v0.38.
Key Advantages of IBC Eureka
⚡ Fast & Affordable Cross-Chain Transfers
Leveraging Skip Go Fast, users experience near-instant asset transfers between chains. For example, moving assets from Ethereum to Cosmos takes only seconds and costs as little as $1 — a fraction of traditional bridge fees.
This efficiency opens up new possibilities for user-facing applications where speed and low cost are critical, such as micropayments, trading, and real-time gaming economies.
🔒 Secure Interoperability You Can Trust
Security is non-negotiable in cross-chain ecosystems. The original IBC protocol (v1), launched in 2021, has maintained a flawless security record — zero exploits to date. IBC v2 builds on this proven foundation with enhanced cryptographic guarantees and improved light client performance.
By using light client-based verification, IBC Eureka ensures that every cross-chain message is cryptographically verified without relying on trusted third parties.
🖱️ Easy 1-Click Transfers for End Users
User experience matters. That’s why IBC Eureka integrates the go.cosmos.network widget, enabling frictionless 1-click transfers across more than 50 popular wallets and front-ends in both Cosmos and Ethereum ecosystems.
No complex configurations. No manual address entry. Just click and go.
Developers can embed this widget directly into their dApps, dramatically lowering the barrier to entry for non-technical users exploring multi-chain functionality.

Flexible Infrastructure for Every Use Case
Not all projects have the same needs. IBC Eureka supports two primary connection models:
1. Aggregated Routing via Cosmos Hub
Ideal for most chains and apps, this model uses the Cosmos Hub as a central routing layer. By establishing just one IBC connection, your chain gains access to the entire IBC network — simplifying maintenance and reducing operational load.
2. Peer-to-Peer (P2P) Connections
For specialized use cases — such as issuing sovereign assets or maintaining control over specific data flows — teams can set up direct P2P connections alongside or instead of hub routing.
This flexibility ensures that both general-purpose and niche applications can thrive within the same ecosystem.
Simplified & Scalable Setup
Gone are the days of deploying and maintaining dozens of relayers across chains. With IBC Eureka:
- All additional IBC connections are managed automatically.
- Relayer infrastructure is lightweight and cost-efficient.
- Deployment complexity is abstracted away from developers.
This means startups and enterprises alike can focus on building innovative products rather than managing networking layers.
Trusted by Industry Leaders
IBC Eureka isn’t just a technical experiment — it’s the interoperability backbone chosen by some of the most forward-thinking projects in crypto:
- Bitcoin security-sharing protocols leveraging Cosmos to create a decentralized world secured by Bitcoin’s hash power.
- A leading Real World Assets (RWA) Layer 1 blockchain designed to comply with regulatory frameworks while enabling tokenization of physical assets.
- The largest decentralized derivatives exchange by volume, offering over 198 markets with deep liquidity, low fees, and up to 100× leverage — all powered by seamless cross-chain access.
These partnerships underscore the trust and scalability that IBC Eureka brings to mission-critical applications.
