We had to recreate the project from a new wallet due to an issue with Gitcoin Indexer (it doesn't loads projects), thou LunCo participated in lots of rounds since GR15, it could be tracked at https://checker.gitcoin.co/public/project/show/lunco-collaborative-systems-engineering

The latest rounds we participated in are (you can find LunCo among participants):

1.  GG21 DeSci https://explorer.gitcoin.co/#/round/42161/387/6 

2. CollabTech round: https://explorer.gitcoin.co/#/round/42161/384/7
