Block Explorer for Holesky Testnet
Ethernal is a hosted block explorer for Holesky, Ethereum's dedicated testnet for validator and staking infrastructure testing. Get transaction decoding, contract verification, and staking contract monitoring for your Holesky environment without running any infrastructure.
Chain ID 17000Interact with Staking Contracts
Deploy and verify staking-related contracts on Holesky, then interact with them directly from the explorer UI. Test deposit contract interactions, withdrawal credential changes, and validator management functions without building a custom frontend. Read contract state and send write transactions in one click.
Built-in Testnet Faucet
The Ethernal Starter plan (free) includes a built-in testnet faucet for your explorer. Visitors can request test ETH directly from your explorer page. No need to set up a separate faucet service or point users to third-party faucets with rate limits and CAPTCHAs.

Why Teams Use a Dedicated Holesky Explorer
Staking Protocol Testing
Test liquid staking contracts (Lido, Rocket Pool, EigenLayer restaking) on Holesky before deploying to mainnet. Track deposit events and withdrawal flows in your own explorer.
Consensus Client Development
Teams building or testing consensus clients (Lighthouse, Prysm, Teku, Nimbus, Lodestar) use Holesky to validate their implementations against a real proof-of-stake network.
Validator Tooling
Build and test validator management dashboards, key management tools, and exit/withdrawal credential workflows with a dedicated explorer that shows only your activity.
Infrastructure Testing
Test your node infrastructure, MEV relay integrations, and network monitoring tools against Holesky before rolling changes out to mainnet validators.
Pricing for Holesky Explorers
The Starter plan (free) is often all you need for a Holesky testnet explorer. It includes contract verification, token tracking, a built-in faucet, and unlimited transactions. For custom domains and branding, the Team plan starts at $150/month.

How do I set up a block explorer for Holesky?
Create a free workspace on Ethernal and paste your Holesky RPC endpoint. Your explorer is live immediately with transaction decoding, contract verification, and a built-in faucet.
What is the difference between Holesky and Sepolia?
Holesky (chain ID 17000) is designed for validator and staking infrastructure testing, with 1.6 billion ETH supply to simulate mainnet staking conditions. Sepolia (chain ID 11155111) is for application development: smart contracts, dApps, and protocol testing. Ethernal supports both.
Is Holesky replacing Goerli?
Yes. The Ethereum Foundation launched Holesky in September 2023 specifically for staking and infrastructure testing, as Goerli was deprecated. Holesky has a much larger ETH supply (1.6B) to better simulate mainnet validator economics.
Can I get free Holesky ETH through Ethernal?
Yes. The Ethernal Starter plan includes a built-in testnet faucet. Users can request test ETH directly from your explorer page without needing a separate faucet service.
Does Ethernal support staking-specific features on Holesky?
Ethernal provides full transaction decoding, contract verification, and call trace debugging for any contract on Holesky, including deposit contracts, liquid staking protocols, and restaking contracts. You can interact with verified staking contracts directly from the explorer UI.
