As previously communicated<\/a>, the Hole\u0161ky testnet has attained its anticipated conclusion date and will be decommissioned shortly. The overwhelming majority of outstanding validator nodes will be terminated 2 weeks following the completion of the Fusaka upgrade on Hole\u0161ky. Afterward, Hole\u0161ky will no longer receive support from client, testing, or infrastructure teams.<\/strong><\/p>\n

<\/p>\n

After the introduction of the Hoodi testnet<\/a> in March 2025, infrastructure providers and staking operators were able to transition their testing activities.<\/p>\n

<\/p>\n

<\/g><\/svg><\/a>Background<\/h2>\n

<\/p>\n

Hole\u0161ky was initiated in 2023 as Ethereum’s largest public testnet, specifically created for evaluating staking infrastructure and validator operations at scale. The network accomplished its goal, allowing thousands of validators to assess protocol enhancements, including the Dencun network improvement<\/a> and most recently, Pectra<\/a>.<\/p>\n

<\/p>\n

However, after the activation of the Pectra testnet in early 2025, Hole\u0161ky faced significant inactivity leaks that resulted in a substantial exit queue. Although the network rebounded and finalized, the prolonged validator exit process rendered it impractical for testing the complete validator lifecycle within acceptable timeframes. This prompted the creation and launch of Hoodi in March 2025, offering a new testing environment free from these limitations.<\/p>\n

<\/p>\n

<\/g><\/svg><\/a>Migration Path<\/h2>\n

<\/p>\n

Staking operators and infrastructure providers ought to transition to Hoodi<\/a><\/strong>, which was launched explicitly to overcome Hole\u0161ky’s limitations. Hoodi offers a new validator set, accommodates all Pectra features, and will implement future protocol upgrades, including the forthcoming Fusaka fork.<\/p>\n

<\/p>\n

Developers of applications and tools<\/strong> who utilized Hole\u0161ky should switch to Sepolia<\/a> instead, which remains the recommended testnet for smart contract and dapp assessments.<\/p>\n
