BlockBeats News, March 19, according to The Block, 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 a test network is a common practice; Ethereum developers previously discontinued Kiln, Ropsten, and Rinkeby in 2022 and stopped Goerli last year. Holesky was launched in September 2023 and is one of Ethereum's two main testnets, the other being Sepolia. It has been a critical public testnet for staking, infrastructure, and protocol development.
