Block Explorer for Sepolia Testnet
Ethernal is a hosted block explorer for Sepolia, Ethereum's primary testnet. Get transaction decoding, contract verification, and token tracking for your Sepolia development environment without running any infrastructure.
Chain ID 11155111Your Own Sepolia Explorer
Sepolia is the recommended Ethereum testnet for application development (replacing Goerli since 2023). While public explorers like Etherscan exist for Sepolia, teams building dApps or protocols often need a private, branded explorer that shows only their contracts and transactions. Ethernal gives you that.

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.

Sign up at app.tryethernal.com and create a new workspace.

Paste a Sepolia RPC URL from any provider: Alchemy (https://eth-sepolia.g.alchemy.com/v2/YOUR_KEY), Infura, QuickNode, or the public endpoint.
Start exploring
Your Sepolia explorer is live. Blocks, transactions, and contracts are indexed automatically. Verify contracts and use the built-in faucet.
Why Teams Use a Dedicated Sepolia Explorer
QA and Testing
Give your QA team a clean explorer that only shows your project's contracts and transactions. No noise from other Sepolia activity.
Demo Environments
Show investors and partners a branded explorer with your logo and domain. More professional than pointing them to a public Etherscan page.
Hackathons and Workshops
Provide participants with a testnet faucet and explorer in one URL. The built-in faucet means no separate faucet management.
Pre-mainnet Staging
Run your Sepolia explorer on the same Ethernal plan you will use for mainnet. When you are ready to launch, just swap the RPC URL.
Pricing for Sepolia Explorers
The Starter plan (free) is often all you need for a Sepolia 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 Sepolia?
Create a free workspace on Ethernal and paste your Sepolia RPC endpoint. Your explorer is live immediately with transaction decoding, contract verification, and a built-in faucet.
Is Sepolia replacing Goerli as the Ethereum testnet?
Yes. The Ethereum Foundation deprecated Goerli in early 2024. Sepolia (chain ID 11155111) is now the recommended testnet for application development. Holesky is used for validator/staking testing.
Can I get free Sepolia 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 Base Sepolia and Arbitrum Sepolia too?
Yes. Ethernal works with any EVM-compatible chain. Connect Base Sepolia (chain ID 84532) or Arbitrum Sepolia (chain ID 421614) the same way you would connect Sepolia. You get the same features plus L2-specific bridge monitoring.
What is the difference between Sepolia and Holesky?
Sepolia is for application developers (smart contracts, dApps, protocol testing). Holesky is for infrastructure and staking testing (validators, consensus clients). Ethernal supports both.
