Holešky Testnet to Shut Down, Migrate to Hoodi & Sepolia
The Ethereum Foundation will decommission the Holešky Testnet two weeks after the Fusaka upgrade concludes. This testnet shutdown ends all client, testing, and infrastructure support on Holešky. Staking operators and infrastructure providers must migrate to the new Hoodi Testnet, which integrates Pectra features and supports the upcoming Fusaka fork. Developers building smart contracts and dapps should transition to Sepolia for application and tooling testing.
After Holešky’s end-of-life, Ethereum’s testnet ecosystem will comprise Sepolia for application testing, Hoodi for full-scale validator operations, and the ephemeral Ephemery Testnet (28-day reset) for lightweight validator lifecycle trials. This migration path and testnet shutdown streamline Ethereum’s testnet roadmap, apply lessons from Holešky’s large-scale validator stress tests, and bolster network resilience ahead of future mainnet upgrades.
Neutral
Shutting down the Holešky Testnet and migrating to Hoodi and Sepolia is a routine infrastructure update with minimal direct impact on ETH’s market price. In the short term, traders may see slight shifts in network activity metrics, but there is no immediate catalyst for significant price movement. Over the long term, the streamlined testnet roadmap and improved stress-testing protocols could enhance Ethereum’s upgrade process and network resilience, indirectly supporting ecosystem confidence but without a strong bullish or bearish signal.
