An EVM-compatible Layer 2 testnet on Ethereum Holesky for Morph, featuring low fees, fast confirmations, and ETH gas for reliable dApp development and validation.
Morph Holesky is the Holesky-based public testnet for the Morph Layer-2, an EVM-compatible rollup on Ethereum that uses testnet ETH for gas. It’s built for developers to deploy and iterate on smart contracts, test cross-chain bridging and messaging, and validate infra such as oracles, indexers, and wallets under mainnet-like conditions. Typical use cases include dApp staging, end-to-end QA, and benchmarking fees and latency before mainnet launches.
Morph Holesky showcases Morph’s modular rollup design—EVM equivalence, Ethereum settlement, and EIP-4844 blob data availability—with a roadmap that supports both optimistic and ZK proving paths for fast confirmations and strong security. Its explorer surfaces real-time performance metrics (average gas cost, block speed, TPS, and network activity), enabling side-by-side comparisons with other L2s. Broad tooling compatibility (Hardhat/Foundry, MetaMask) and low testnet fees make rapid iteration and load testing straightforward.
Morph 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 Morph Holesky, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select Morph Holesky as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
To build on Morph 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.
To add Morph Holesky 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 Morph Holesky, ensure your wallet is connected to the Morph Holesky network, enter the recipient's address, specify the amount of ETH to send, review the gas fee, and confirm the transaction in your wallet.
