According to the source, there is an unverified claim that the Ethereum Foundation will begin degrading the Holesky testnet with node operators shutting down nodes over roughly 10 days; traders should wait for confirmation via official Ethereum Foundation channels before positioning, as third-party posts are not authoritative (source: https://blog.ethereum.org, https://github.com/ethereum/pm, https://ethereum.org/en/developers/docs/networks/testnets). Official Ethereum testnet changes and deprecations are typically announced on the Ethereum Foundation blog and coordinated through AllCoreDevs and client-team repositories, which act as the canonical record for timelines and procedures (source: https://blog.ethereum.org, https://github.com/ethereum/pm). Holesky is a public Ethereum testnet intended for large-scale validator and infrastructure testing, and testnet events do not affect mainnet ETH balances or mainnet consensus, limiting direct market risk from testnet-only actions (source: https://ethereum.org/en/developers/docs/networks/testnets). If a Holesky wind-down were officially confirmed, developers and validators would likely migrate additional workloads to Sepolia, the other recommended testnet for application flows, which can temporarily impact devops pipelines but not mainnet activity or user funds (source: https://ethereum.org/en/developers/docs/networks/testnets). Traders should monitor the Ethereum Foundation blog, AllCoreDevs coordination repo, and client releases for any dated Holesky notice and adjust only after an official publication is live (source: https://blog.ethereum.org, https://github.com/ethereum/pm).
