# IBC Eureka: Fast, Cheap, and Seamless Interoperability between Cosmos and Ethereum

## What is IBC Eureka?

IBC Eureka is the canonical implementation of IBC v2 that enables seamless interoperability between Cosmos and Ethereum ecosystem. As a subset of the proven Inter-Blockchain Communication (IBC) protocol, Eureka extends the reach of 115+ Cosmos chains to Ethereum (Q1 2025) with support for Layer 2 networks such as Base and Arbitrum or Solana to be added soon.

    Connect your Cosmos chain to Ethereum and other EVM chains with minimal cost and battle-tested security.
  </Card>

  <Card title="Instant Compatibility" icon="puzzle">
    If your chain already uses IBC, is connected to the Cosmos Hub and has been onboarded to the Skip API, you can immediately connect to Ethereum through Eureka with no new dependencies.

## Getting Started

To start using Eureka, you have several options:

<Steps>
  <Step title="Understand the Tech">
    Read the [Technical Overview](/skip-go/eureka/eureka-tech-overview) to see how Eureka works.
  </Step>

  <Step title="Asset Issuers: Integrate with Eureka via Custom ERC20">
    If you're an asset issuer, the path to integrating your token with Eureka and maintaining control over its representation on Ethereum is by deploying a [Custom ERC20](/skip-go/eureka/custom-erc20-integration). Follow our guide to learn how.
