Ethereum’s Glamsterdam testnet hits setback – Why Solana remains ahead

Ethereum’s [ETH] main upgrade agenda in 2026 has hit a hiccup. The much-awaited Glamsterdam upgrade, initially scheduled to go live on the Hoodi testnet on the 26th of October, has been cancelled. According to security firm Chain Security, the Hoodi testnet was paused after they identified security flaws that have already impacted 13 projects and counting. We already found 13 real-world examples and are in responsible disclosure with the affected projects. Please check your contracts as soon as possible, as the EF is determining how many contracts are impacted in which way.
