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.
