A developer-friendly EVM-compatible blockchain testnet for KuCoin Community Chain (KCC), offering fast finality and low fees with chain ID 322 and tKCS gas.
KCC Testnet is the public testing environment for KuCoin Community Chain (KCC), an EVM-compatible network that uses tKCS as its native gas token. It’s used to deploy and iterate on smart contracts, bridges, and dApps, perform end-to-end QA, and validate upgrades with faucet-funded tKCS and on-chain visibility via https://scan-testnet.kcc.network.
KCC Testnet prioritizes fast confirmations and low costs, delivering ~3-second block times and ultra-low fees (gas commonly ~1 gwei; an ERC-20 transfer is typically <0.0001 tKCS). It’s designed for high throughput (hundreds TPS under load) while real-world testnet activity is usually low (often <1 TPS), creating a stable, low-latency environment with full Ethereum tooling compatibility for seamless porting and benchmarking.
KCC Testnet uses tKCS as the gas token for transaction fees. You can obtain tKCS by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).
To bridge tKCS to KCC Testnet, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select KCC Testnet as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
To build on KCC 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 KCC 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 tKCS on KCC Testnet, ensure your wallet is connected to the KCC Testnet network, enter the recipient's address, specify the amount of tKCS to send, review the gas fee, and confirm the transaction in your wallet.
