A fresh slate of Ethereum testnets is Replacing the holeThe former massive staging ground is set today for shutdown after a two-year service.
Wind-down will take place two weeks after the Fusaka upgrade will be finalized later this year, at this point clients and infrastructure teams will stop providing support.
Fusaka is set to make Ethereum rollups cheaper and faster by spreading “data storage” equally equal to the entire validators.
Holesky lived live in 2023 in the proof-of-stake machinery of the stress-test Ethereum on the scale. It quickly became the largest public testnet, providing thousands of validators with a platform on trial upgrades before they were deployed to Mainnet.
Basic milestone, such as Dencun and Pectra upgrades – lowering the transaction costs and upgrading validator efficiency, among other features – are operated first.
However, cracks began to appear as the aged network. Hollesky encountered a “inactive leak” after Pectra’s activation in early 2025, a term that refers to validators that have turned on as many as, which created a significant backlog for attempts to emerge.
The result was months queues that became impractical to test the entire validator lifecycle. For developers who need fast feedback loops, holesky has become more of a road barrier than a tool.
That’s why Ethereum launched Hoodi in March 2025, a clean slate testnet developed to register holesky’s problems while playing its role as a go-to environment for validator and staking provider testing.
Next to Hoodi, Sepolia continues to serve as the main testnet for dapps (Decentralized Apps) And smart contracts, while ephemery offers fast validator rotations every 28 days.
Ether (Et) was trading at $ 4,380 on Asian morning hours Tuesday, almost flat in the past 24 hours.
