In May 2026, a gathering of core Ethereum developers from various client teams took place on the Svalbard archipelago in Norway. This event, known as an interop, is held periodically to coordinate efforts among different groups working on the protocol.

Over the course of the week, participants focused on enhancing network stability and technically preparing for the upcoming upgrade codenamed Glamsterdam. Primary attention was directed toward eliminating potential vulnerabilities and ensuring a seamless transition to the new protocol version.

Such meetings represent a critically important stage in Ethereum's development cycle, allowing independent teams to synchronize their work before implementing changes in the main network. The remote location underscores the drive for concentrated work free from external distractions.
