Hello Altair community,
Polkadotters here! 
Maybe you know us by following our Twitter or our Medium channel, where we bring content about all Dotsama ecosystem projects and explaining all the Polkadot peculiarities to our beloved community 
We have been a huge supporter of the Centrifuge ecosystem from the very beginning with our first review of the project dating all the way back to then Oct 2020. We also pooled together with our Czech Polkadot community to be part of the Tinlake and successfully provided liquidity for a couple of projects. And last but not least, we really proud to be one of the active validators in the Centrifuge!
Regarding our validation/collation experience, we are proud members of the 1000 validators program on both Polkadot and Kusama and we also validate on basically all Dotsama networks because we believe that involvement of community validators is healthy for the network
List of projects where we are currently active
- Polkadot (Astar, Moonbeam & more coming soon)
- Kusama (Kilt, Shiden, Moonriver, Darwinia Crab, Statemine, Bifrost, Kintsugi, Calamari and soon Picasso or Basilisk are coming)
