EVM Co-Chain & Cosmos SDK Support
Kava is a unique Layer-1 blockchain featuring co-chain architecture combining Cosmos SDK and Ethereum EVM in a single network. This innovative design enables developers to build with either Cosmos or Ethereum tools while benefiting from seamless interoperability between both ecosystems. As a cross-chain DeFi platform, Kava connects Bitcoin, Ethereum, Cosmos, and other major chains through IBC and bridges.

Access dual-architecture DeFi platform
A Kava RPC node provides applications with access to a unique blockchain running both Cosmos SDK and EVM simultaneously in a co-chain architecture. This means developers can build with Cosmos tools (CosmWasm, IBC) or Ethereum tools (Solidity, ethers.js) on the same chain, with seamless communication between both environments.
Most blockchains force a choice: Cosmos OR Ethereum. Kava offers both through co-chain architecture where Cosmos SDK and EVM run in parallel, sharing security and state. This enables Cosmos dApps to interact with Ethereum dApps natively, unlocking powerful cross-chain composability.
Kava advantages:
Kava runs two execution environments on one blockchain: the Cosmos Co-Chain (Cosmos SDK, CosmWasm) and the Ethereum Co-Chain (EVM). Both share the same validators and security through Tendermint consensus. A translator module enables seamless communication between Cosmos and Ethereum smart contracts.
Kava architecture:
Kava serves as a cross-chain DeFi hub connecting major blockchains through bridges and IBC. Users can supply BTC, ETH, ATOM, and other assets to Kava's DeFi protocols like Kava Lend (money market), Kava Mint (CDP stablecoin), and Kava Swap (DEX).
This cross-chain approach creates unified liquidity and enables strategies impossible on single-chain DeFi platforms.
Quick start for developers
Kava EVM Co-Chain supports all standard Ethereum JSON-RPC methods:
const { ethers } = require('ethers');
const provider = new ethers.JsonRpcProvider('https://rpc.crypto-chief.com/kava/YOUR_API_KEY');
// Verify we're on Kava EVM Co-Chain
const network = await provider.getNetwork();
console.log('Chain ID:', network.chainId); // 2222
// Get KAVA balance
const balance = await provider.getBalance('0x...');
console.log('KAVA Balance:', ethers.formatEther(balance));
// Interact with Kava Lend
const KAVA_LEND = '0x...';
const lendABI = [
'function supply(address asset, uint256 amount) external',
'function getAccountLiquidity(address) view returns (uint256)'
];
const lend = new ethers.Contract(KAVA_LEND, lendABI, provider);
const liquidity = await lend.getAccountLiquidity('0x...');
console.log('Account liquidity:', ethers.formatEther(liquidity));from web3 import Web3
w3 = Web3(Web3.HTTPProvider('https://rpc.crypto-chief.com/kava/YOUR_API_KEY'))
print('Connected to Kava:', w3.is_connected())
print('Chain ID:', w3.eth.chain_id) # 2222
print('Latest block:', w3.eth.block_number)
# Get KAVA balance
balance = w3.eth.get_balance('0x...')
print(f'KAVA: {balance / 1e18}')const { ethers } = require('ethers');
const provider = new ethers.WebSocketProvider('wss://rpc.crypto-chief.com/kava/ws/YOUR_API_KEY');
// Monitor new blocks
provider.on('block', async (blockNumber) => {
const block = await provider.getBlock(blockNumber);
console.log(`Kava block ${blockNumber}: ${block.transactions.length} txs`);
});
// Monitor cross-chain deposits
const BRIDGE = '0x...';
const filter = {
address: BRIDGE,
topics: [ethers.id('Deposit(address,uint256,bytes32)')]
};
provider.on(filter, (log) => {
console.log('Cross-chain deposit on Kava:', log);
