Ethereum developers plan to end support for the Holesky test network in September and launch a new test network, Hoodi

Odaily Planet Daily reports that Ethereum core developers plan to end support for the Holesky testnet in September 2025, and are preparing for its role transition and eventual deprecation. Deprecating testnets is a common practice; Ethereum developers previously stopped Kiln, Ropsten, and Rinkeby in 2022, and Goerli last year. Launched in September 2023, Holesky was one of Ethereum's two main testnets, with Sepolia being the other.

It has always been a key public testnet for staking, infrastructure development and protocol development. In addition, the new Hoodi testnet has already been launched and will initiate the Pectra network upgrade on March 26th - ahead of the expected mainnet release in Q2. The foundation added that future staking operators and infrastructure providers should use Hoodi for validator testing.
