On November 6, the Ethereum Foundation announced in a blog post by developer Marius van der Wijden that Glamsterdam will only move to the Hoodi testnet once the problems found during testing have been resolved. The trigger is two changes to gas costs, EIP-8037 and EIP-8038, which according to the auditing firm ChainSecurity could leave existing smart contracts open to attack. Ether traded at $2,233 on Saturday evening according to CoinGecko, roughly €2,005, which put it 11.7 percent below its level of 30 days earlier.
