An EVM-compatible Cosmos testnet (Chain ID 2221) for deploying and testing Solidity dApps with IBC interoperability, fast finality, and low-fee TKAVA transactions.
Kava Testnet is a public, valueless-TKAVA network that mirrors Kava’s dual-stack architecture (EVM Co-Chain + Cosmos SDK/IBC Co-Chain) so teams can validate dApps, cross-chain flows, and protocol upgrades before mainnet. Typical use cases include deploying and debugging Solidity smart contracts with Ethereum RPC, rehearsing IBC integrations and bridge routes, and testing validator operations and governance. For performance context, testnet offers near-zero gas fees, multi-second block times (≈2–6s), and high throughput sufficient for stress testing via both EVM and Cosmos endpoints.
Kava Testnet is unique because it combines an EVM execution layer with a Cosmos IBC-native chain in one network, enabling seamless asset/account movement and cross-chain messaging without external wrappers. Developers get Ethereum tooling (Solidity, MetaMask, EIP-1559) plus deterministic CometBFT finality, yielding predictable confirmations and low, stable fees; blocks land in a few seconds with throughput in the hundreds of TPS on test loads. Compared to single-stack EVM testnets, this dual environment lets you benchmark gas and latency across both ecosystems while observing real IBC activity on a production-like validator set.
Kava Testnet uses TKAVA as the gas token for transaction fees. You can obtain TKAVA by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).
To bridge TKAVA to Kava Testnet, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select Kava Testnet as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
To build on Kava Testnet you can use thirdweb, which provides an easy way to build, monetize and scale your apps, games or agents. You can find detailed guides and documentation on https://portal.thirdweb.com to get started quickly.
To add Kava Testnet to your wallet, you can connect your wallet and click on [Add to Wallet] button at the top of the page. Alternatively, you can add the network manually using the RPC URL and chain details and add it to your wallet's network settings.
To send TKAVA on Kava Testnet, ensure your wallet is connected to the Kava Testnet network, enter the recipient's address, specify the amount of TKAVA to send, review the gas fee, and confirm the transaction in your wallet.
