Glamsterdam Test: Attackers Could Exploit Free Testnet ETH to Win Sepolia Block Auctions and Withhold Transaction Payloads

Odaily reports: Ethereum developers have warned that attackers could exploit free testnet ETH and one-time builder identities to win Sepolia block auctions and withhold transaction payloads during the Glamsterdam testing period.

This attack does not threaten mainnet funds, but it could disrupt infrastructure testing. The Sepolia public test is scheduled to launch on October 6, while the Hoodi test is tentatively set for October 27. The mainnet activation date remains undetermined. (CoinDesk)
