Ethereum’s Glamsterdam upgrade could disrupt existing smart contracts

Ethereum developers have introduced two competing proposals to prevent the upcoming Glamsterdam upgrade from disrupting existing smart contracts as concerns grow over changes to the network's gas pricing rules. Ethereum developers Leo Glisic and Giulio Rebuffo have submitted competing proposals to prevent Glamsterdam's revised gas pricing from disrupting existing smart contracts. Glisic wants older contracts to retain their existing gas rules, while Rebuffo has proposed separate accounting systems to preserve contract execution under the previous rules. Security researchers have warned that roughly 200,000 contracts could be affected, with concerns extending to established DeFi protocols and applications holding user funds. Curve Finance founder Michael Egorov warned of a possible emergency hard fork, while Ethereum investor Ryan Berckmans withdrew his earlier support for rapid activation.
