And if you’ve been complaining about gas fees or slow transactions... this one’s for you.

#### *So what is Glamsterdam?*
Think of it as Ethereum’s next big update. After Pectra, Glamsterdam is next in line for 2027.

The team isn’t promising magic. They’re promising speed.

#### *3 Things That Actually Matter:*
1. *Faster blocks*: Right now Ethereum does 1 block every 12 seconds. Glamsterdam is testing 4 seconds. That means your swap confirms before you can blink.
