As a limited event at Jadu, you could stake one or several boards for 30+ days and get an upgrade.
If you staked one board, you would get an upgraded design, and if you staked 2 boards, you would get your lower-tier board upgraded to the body of the higher-tier one, while your board kept its distinct colouring features.
This was a very exciting project for me because of the sheer amount of the possible combinations. – 2022
Quick selection of my favourite combos.
