Kava RPC Endpoint

Fast, flat-rate Kava RPC node provider — free tier, no KYC, HTTP & WebSocket.

Kava is a Cosmos-based Layer 1 with a co-chain architecture that pairs a Cosmos SDK chain with a fully compatible Ethereum (EVM) co-chain. It runs on Tendermint consensus and uses KAVA as the gas and staking token across both environments.

About Kava

Kava's co-chain design connects a Cosmos co-chain and an EVM co-chain through a Translator module, letting Cosmos and Ethereum developers build on one network. The EVM co-chain went live with the Kava 10 upgrade and uses Tendermint Core consensus for roughly 6-second blocks and single-block finality.

Kava EVM is fully Ethereum-compatible, so Solidity contracts and tools such as Hardhat, Foundry, and MetaMask work unchanged. KAVA is the native gas and staking token for both co-chains, and IBC connectivity links Kava to the broader Cosmos ecosystem.

Common Use Cases on Kava

• EVM DeFi (lending, DEXes, stablecoins)
• Cross-ecosystem Cosmos and Ethereum apps
• IBC asset transfers
• KAVA staking and governance
• Smart contract deployment in Solidity

Kava Ecosystem

Hosts DeFi protocols including Kava Lend and Kava Mint, plus EVM DEXes and integrations bridging Cosmos and Ethereum liquidity.
