Ethereum's Glamsterdam upgrade has entered its final development phase and is expected to launch on the mainnet in the second half of the year.

CoinFeed reported on June 17th, citing CoinDesk, that Ethereum developers have entered the final development phase of the Glamsterdam upgrade, running a developer network (devnets) containing all planned EIPs before deployment to the public testnet. Ethereum Foundation core developer Parithosh Jayanthi stated that this is the final stage before codebase hardening and testnet launch, and while there is no fixed timeline, significant progress has been made. Glamsterdam, expected to launch its mainnet in the second half of this year, is described as "the largest upgrade since the merger," changing many assumptions about Ethereum and laying the foundation for future large-scale expansion.
