An EVM-compatible blockchain, Bitkub Chain uses proof-of-staked-authority (PoSA) to deliver low fees and fast finality for Thailand’s Web3 ecosystem powered by KUB.
Bitkub Chain is an EVM-compatible Layer-1 mainnet from Thailand powered by the KUB token, built for consumer payments, DeFi, NFTs, and enterprise tokenization across the Bitkub ecosystem (e.g., Bitkub NEXT wallet, NFT marketplace). It targets low-cost, high-frequency transactions for retail and enterprises, with typical performance of ~5-second block times, sub-cent average gas fees in KUB, and practical throughput in the tens to low-hundreds TPS; see the Bitkub Chain explorer for live activity data.
Bitkub Chain is unique for its Thailand-first, compliance-ready stack—native fiat on/off-ramps via Bitkub Exchange, KYC-enabled Bitkub NEXT wallet/ID, and localized enterprise support—while remaining fully EVM-compatible for easy migration of Solidity dApps and tooling. Compared with larger global L1s, it delivers faster confirmations and lower fees for retail use cases (avg fee usually <$0.01; block time ~5s vs ~12s on Ethereum; observed throughput up to low-hundreds TPS; active daily micro-transactions in the Thai market), streamlining cross-chain and consumer app integrations.
Bitkub Chain uses KUB as the gas token for transaction fees. You can obtain KUB by bridging from other chains or purchasing using thirdweb Bridge.
To bridge KUB to Bitkub Chain, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select Bitkub Chain as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
To build on Bitkub Chain 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 Bitkub Chain 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 KUB on Bitkub Chain, ensure your wallet is connected to the Bitkub Chain network, enter the recipient's address, specify the amount of KUB to send, review the gas fee, and confirm the transaction in your wallet.
