An EVM-compatible blockchain testnet, ThunderCore Testnet delivers 1-second confirmations and ultra-low fees for developers to test Ethereum-compatible dapps using TST (Chain ID 18).
ThunderCore Testnet is an EVM-compatible staging network mirroring ThunderCore mainnet, using TST as the native currency so developers can safely test smart contracts, dApps, and cross-chain bridge flows. It offers ~1-second block times, high throughput (4,000+ TPS capacity), and negligible gas costs (testnet TST via faucet; on mainnet typically under $0.0001/tx), enabling realistic load and performance testing before deployment.
Compared to many testnets, ThunderCore Testnet delivers near-instant finality (~1 s blocks), high throughput (4,000+ TPS capacity), and very low fees (avg cost typically < $0.0001/tx on mainnet; free TST via faucet on testnet). It remains fully EVM-equivalent with popular tooling (MetaMask, Hardhat, Foundry) and stable public RPC/explorer, enabling accurate benchmarking for bridges and high-volume dApps. Public testnet activity naturally fluctuates, but the network is engineered to sustain heavy load during stress testing—unlike throttled or slower testnets (e.g., ~12 s blocks and <20 TPS on Ethereum).
ThunderCore Testnet uses TST as the gas token for transaction fees. You can obtain TST by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).
To bridge TST to ThunderCore Testnet, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select ThunderCore Testnet as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
To build on ThunderCore 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 ThunderCore 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 TST on ThunderCore Testnet, ensure your wallet is connected to the ThunderCore Testnet network, enter the recipient's address, specify the amount of TST to send, review the gas fee, and confirm the transaction in your wallet.
