Hoodi RPC FAQ

What is the Hoodi Testnet RPC URL?

The Hoodi Testnet RPC URL with BoltRPC is `https://eu.endpoints.matrixed.link/rpc/ethereum-hoodi?auth=YOUR_KEY`. Replace `YOUR_KEY` with your API key from [trial.boltrpc.io](https://trial.boltrpc.io). The chain ID is 560048.

What replaced Holesky testnet?

Hoodi is the successor to Holesky as the primary Ethereum testnet for staking and validator testing. Holesky was deprecated after issues with its validator set size. Hoodi is designed with long-term stability in mind for infrastructure teams and protocol developers.

How do I get test ETH for Hoodi?

Use Ethereum ecosystem faucets that support Hoodi. Search for "Hoodi faucet" or check the Ethereum Foundation's testnet resources at ethereum.org for current faucet links. Test ETH on Hoodi has no real value and is only used for testing.

What is Hoodi used for?

Hoodi is Ethereum's long-term testnet for staking and validator infrastructure. It is used by teams building: validator client software, liquid staking protocols, restaking systems, and any infrastructure that needs to test deposit and withdrawal flows. Hoodi is not a general-purpose dApp testnet, for smart contract testing, Sepolia is the recommended choice.

How do I add Hoodi to MetaMask?

Open MetaMask, go to Settings, then Networks, then Add Network, and enter: Network Name: BoltRPC Hoodi Testnet, RPC URL: `https://eu.endpoints.matrixed.link/rpc/ethereum-hoodi?auth=YOUR_KEY`, Chain ID: 560048, Currency Symbol: ETH, Block Explorer: https://hoodi.ethpandaops.io.

Why use a paid RPC provider for a testnet?

Public testnet RPCs are shared and often unreliable: they drop connections during congestion, return stale data, and impose strict rate limits. For infrastructure teams running automated validator testing and CI/CD pipelines, a flaky testnet endpoint causes false test failures and wasted debugging time. BoltRPC's testnet access is included in all plans alongside mainnet access.

What is the difference between Hoodi and Sepolia?

Hoodi is designed for validator and staking infrastructure testing: deposit contract testing, withdrawal flows, and validator client development. Sepolia is the general-purpose Ethereum dApp testnet for smart contract development and application testing. If you are building a dApp, use Sepolia. If you are building staking or validator infrastructure, use Hoodi. The distinction matters for RPC usage as well: Sepolia sees general developer traffic, while Hoodi traffic is dominated by validator client software, staking protocol backends, and automated CI/CD pipelines for infrastructure teams. This makes Hoodi's public RPC particularly unreliable for infrastructure-grade workflows that depend on consistent uptime.

Who should use the Hoodi testnet?

Hoodi is specifically intended for teams building Ethereum consensus layer infrastructure: validator client developers testing new releases, liquid staking protocol teams validating deposit and withdrawal flows, restaking protocol teams testing EigenLayer-style staking mechanisms, and node operators testing configuration before running validators with real ETH. Application developers building smart contracts, NFTs, or DeFi protocols should use Sepolia instead. The deposit contract on Hoodi mirrors Ethereum mainnet's deposit contract, allowing infrastructure teams to test the full validator lifecycle including activation, attestation, and exit without risking real ETH.
