Odaily News 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 common practice, with Ethereum developers previously discontinuing Kiln, Ropsten, and Rinkeby in 2022 and Goerli last year. Holesky, launched in September 2023, is one of Ethereum's two main testnets, the other being Sepolia. It has been a key public testnet for staking, infrastructure, and protocol development.
In addition, a new testnet, Hoodi, has been launched and will initiate the Pectra network upgrade on March 26, ahead of the expected Q2 mainnet launch. The foundation added that future staking operators and infrastructure providers should use Hoodi for validator testing.
