An EVM-compatible Layer 1 blockchain featuring non-invasive interoperability via Dual Node technology, enabling seamless cross-chain dApps with low fees and fast finality.
KardiaChain is an EVM-compatible Layer-1 mainnet that uses the KAI token and focuses on interoperable, consumer-grade Web3 in Vietnam and Southeast Asia. Primary use cases include low-fee DeFi (DEXs, staking), gaming/NFTs, and enterprise integrations, with seamless cross-chain asset transfers enabled by its Dual Node architecture.
KardiaChain’s Dual Node and non-invasive interoperability allow smart contracts on different chains to communicate without modifying their source chains, complemented by Elastic Sharding with Incentive Mechanism for scalability. In practice, it offers very low average transaction fees (typically well under $0.01), quick finality with ~5-second blocks, and measured throughput in the tens-to-low-hundreds TPS with steady daily activity—making it faster and cheaper than Ethereum L1 while remaining EVM-native; check the KardiaChain explorer for live metrics on gas cost, block speed, TPS, and active addresses.
KardiaChain uses KAI as the gas token for transaction fees. You can obtain KAI by bridging from other chains or purchasing using thirdweb Bridge.
To bridge KAI to KardiaChain, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select KardiaChain as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
To build on KardiaChain 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 KardiaChain 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 KAI on KardiaChain, ensure your wallet is connected to the KardiaChain network, enter the recipient's address, specify the amount of KAI to send, review the gas fee, and confirm the transaction in your wallet.
