A developer-focused blockchain testnet, Hela Official Runtime Testnet mirrors mainnet conditions with Chain ID 666888 and HLUSD as the native currency for fees.
Hela Official Runtime Testnet is a public test environment for Hela’s runtime where transactions and gas fees are paid in the native HLUSD test currency. It enables developers and infrastructure teams to safely test cross-chain bridge workflows, smart-contract logic, and wallet/explorer integrations before mainnet, supporting performance benchmarking and QA without financial risk.
Hela Official Runtime Testnet is differentiated by using HLUSD as the native gas token, delivering stable, predictable fees that simplify benchmarking and fee estimation across versions. It is purpose-built to validate bridge-centric runtime features end to end, making it better for cross-chain interoperability testing than general-purpose testnets; for up-to-date comparisons on average gas cost (in HLUSD), block speed, TPS, and network activity, refer to the explorer/docs linked at helalabs.com because metrics can change during active development.
Hela Official Runtime Testnet uses HLUSD as the gas token for transaction fees. You can obtain HLUSD by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).
To bridge HLUSD to Hela Official Runtime Testnet, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select Hela Official Runtime Testnet as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
