EVM Wallet Compatibility​

Any standard EVM wallet works out of the box with Cosmos EVM chains. This includes popular wallets like MetaMask, Rabby, WalletConnect, and any other wallet that supports Ethereum and EVM-compatible chains. No special configuration or custom integration is required - simply add your chain’s RPC endpoint and chain ID to any EVM wallet.

​
Key Integration Points​

  • Standard EVM RPC: Cosmos EVM exposes the standard Ethereum JSON-RPC API, ensuring compatibility with all EVM wallets
  • EIP-1559 Support: Full support for EIP-1559 dynamic fee transactions, enabling automatic gas estimation
  • Address Format: Uses standard Ethereum addresses (0x format) for EVM transactions
  • Transaction Types: Supports all standard Ethereum transaction types including legacy and EIP-1559 transactions

Quick Start​

To add a Cosmos EVM chain to MetaMask or any EVM wallet:
  1. Open your wallet and navigate to “Add Network”
  2. Enter the following details:
    • Network Name: Your chain name
    • RPC URL: Your chain’s JSON-RPC endpoint (port 8545)
    • Chain ID: Your EVM chain ID (integer)
    • Currency Symbol: Your native token symbol
    • Block Explorer URL: (optional) Your chain’s block explorer
That’s it! Your wallet is now ready to interact with the Cosmos EVM chain.
