Ethereum Compatibility

Deploy existing Solidity contracts, use familiar tools like MetaMask, Hardhat, and Foundry

Cosmos Native Features

Access staking, governance, IBC, and other Cosmos SDK modules directly from smart contracts

Instant Finality

1-2 second block times with instant finality via ‘CometBFT’ consensus

Cross-Chain Ready

Built-in IBC support for interoperability across a growing list of ecosystems

​
Why Cosmos EVM

Cosmos EVM provides a production-ready foundation for building EVM-compatible blockchains with the full power of the Cosmos SDK. The repository includes evmd, a fully functional reference implementation that serves as the canonical starting point for teams launching their own chains.

​
Complete EVM Compatibility

From a developer’s perspective, chains built with Cosmos EVM are indistinguishable from canonical EVM chains like Ethereum mainnet. Your existing tooling, workflows, and even AI coding assistants work without modification:
  • Deploy contracts using Hardhat, Foundry, or Remix exactly as you would on Ethereum
  • Connect wallets like MetaMask, WalletConnect, or Rabby without custom configuration
  • Use standard libraries such as ethers.js, viem, and web3.js with zero changes
  • AI tools work seamlessly - Claude, ChatGPT, and other AI assistants treat your local testnet as if it’s Ethereum mainnet, deploying contracts and interacting with them using standard Ethereum patterns
All user-facing components are identical. The difference lies in what happens under the hood: instant finality, native IBC interoperability, and direct access to Cosmos SDK modules from your smart contracts.

The Easiest Way To Launch an EVM Layer 1

​
Advantages of Starting with Cosmos-EVM

Building with Cosmos-EVM comes with numerous benefits::
  • Greater compatibility - Direct alignment with the module’s development ensures configurations work as intended
  • Improved troubleshooting - Similarity to the base project simplifies diagnosing and resolving issues
  • Proven architecture - At the core of Cosmos-SDK is go-ethereum (Geth), the most widely used and battle-tested Ethereum client
  • Production ready - Fully audited codebase (read our audit)
  • Active ecosystem - Join a growing number of projects already running Cosmos EVM and be part of the shift to more efficient, affordable networks
  • Faster go-to-market - Launch your EVM-compatible chain in weeks, not months by using evmd as a foundation

Customize and deploy your own layer one EVM network.

Use our evmd reference network as a starting point for bootstrapping your own blockchain with full EVM compatibility, from start to finish.
