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_API_KEY. Replace YOUR_API_KEY with your API key from 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 for long-term stability for infrastructure teams.

How do I get test ETH for Hoodi?

Use Ethereum ecosystem faucets that support Hoodi. Search for Hoodi faucet or check ethereum.org for current faucet links. Test ETH on Hoodi has no real value.

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 infrastructure that needs to test deposit and withdrawal flows.

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_API_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 drop connections during congestion, return stale data, and impose strict rate limits. For infrastructure teams with automated validator testing and CI/CD pipelines, a flaky testnet endpoint causes false failures and wasted debugging time.

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. Build dApps on Sepolia. Build staking infrastructure on Hoodi.

Why BoltRPC

Built for teams that ship on Hoodi.

Free trial access with mainnet-parity infrastructure

BoltRPC's 2-week free trial includes testnet access. Your Hoodi workflow uses the same endpoint format, the same API key, and the same infrastructure quality as your Ethereum mainnet setup. No separate accounts or configurations for testnet.

Built for validator and staking infrastructure

Hoodi is specifically designed for long-term Ethereum protocol testing, with a focus on validator and staking infrastructure. Teams building validator tooling, liquid staking protocols, and restaking systems use Hoodi as their staging environment. Reliable testnet RPC access matters when you are building infrastructure that will run in production.

Stable testnet infrastructure for CI/CD

Public testnet RPCs drop connections, hit rate limits, and lag behind the chain tip. BoltRPC gives your Hoodi workflows the same stability as your mainnet setup. No broken test pipelines from unreliable endpoints.

Mirror your mainnet setup

Use BoltRPC on Hoodi and Ethereum mainnet from the same provider. One API key, one endpoint format, one configuration to manage.

WebSocket for testnet event monitoring

Subscribe to Hoodi testnet events via WebSocket. Useful for integration test suites that need real-time block confirmation events.

: The Hoodi Testnet RPC URL with BoltRPC is `https://eu.endpoints.matrixed.link/rpc/ethereum-hoodi?auth=YOUR_API_KEY`. Replace `YOUR_API_KEY` with your API key from [trial.boltrpc.io](https://trial.boltrpc.io). The chain ID is 560048.
: 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.
: 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.
: 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.
: 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_API_KEY`, Chain ID: 560048, Currency Symbol: ETH, Block Explorer: https://hoodi.ethpandaops.io.
: 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.
: 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.
: 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.
