From launching an app to successfully completing a seed round, the past year has been an exciting one at Numio. It was the year when we launched the first ever zkRollups app on Google Play, mastered the tech for faster and cheaper Ethereum transactions, supercharged ourselves by getting VC funding, and built the foundation to take Layer 2 tech to the next level in 2022.
In this short post we take a look at just some of our achievements during 2021.
December 2020/January 2021
Depending on where you live in the world it was on the 31st December 2020/1st January 2021 that we quietly launched the first ever zkRollup powered mobile app to registered users on Google Play.
On the 31st December 2020 I made my first transaction on the #zkSync network using the first public release of the @GetNumio app - it was a big start to a big year
