GLHF Testnet is a public test network for the GLHF ecosystem that uses test ETH for gas and is intended for safe end-to-end validation of the GLHF cross-chain bridge. Typical use cases include deploying and upgrading contracts, simulating bridge flows (lock/mint/burn/redeem), and verifying wallet, relayer, and RPC integrations without risking mainnet funds.
GLHF Testnet focuses on cross-chain bridge workflows and ETH-native gas, offering drop-in compatibility with common Ethereum developer tooling for faster iteration. As of September 2025, the network has not published official performance benchmarks (average gas cost, block speed, TPS, or activity); for comparison against Sepolia/Holesky, measure your own metrics via a block explorer and RPC latency tests using identical transactions.
GLHF Testnet uses ETH as the gas token for transaction fees. You can obtain ETH by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).
To bridge ETH to GLHF Testnet, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select GLHF Testnet as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
To build on GLHF 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 GLHF 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 ETH on GLHF Testnet, ensure your wallet is connected to the GLHF Testnet network, enter the recipient's address, specify the amount of ETH to send, review the gas fee, and confirm the transaction in your wallet.
