An EVM-compatible testnet on Ethereum’s Holesky, Garnet Holesky uses ETH gas (chain ID 17069) to enable low-cost, production-like decentralized application and infrastructure testing.
Garnet Holesky is an Ethereum testnet network aligned with Holesky that uses ETH as the native gas token and is maintained by the Redstone ecosystem (see redstone.xyz). It’s built for safe, end-to-end testing of EVM dApps, wallets, oracles, and cross-chain bridges before mainnet. For comparison, monitor its key performance on the explorer: average gas cost (negligible test ETH), block speed (seconds-level), TPS/throughput (higher than L1 under load), and live activity (tx volume, unique addresses).
Garnet Holesky is unique for being an ETH-native, EVM-equivalent Holesky testnet with production-like confirmation behavior, stable public endpoints, and faucet support—making it ideal for realistic cost/latency benchmarking of bridges and rollups. Versus mainnet and many public testnets, it offers materially lower average gas, faster block cadence, and higher achievable TPS for stress testing, with real-time metrics (avg gas, block time, TPS, and activity) available on its explorer for apples-to-apples comparisons.
Garnet Holesky 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 Garnet Holesky, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select Garnet Holesky as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
To build on Garnet Holesky 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.
