I'm about to give up on Gitcoin.
there are rounds that aren't on PGN, so I checked with one on Polygon that features some worthwhile projects added them to the card, tried to check out paying USDC. the transaction doesn't go through, high fees, tx reverted. several attempts.
changed the browser (that has a different wallet app), connected, and much to my surprise the card was empty. added the projects again only to experience the same problems when checking out.
I don't start bothering with PGN now. someone should should initiate a big grants round for Gitcoin, so they can fix their tech in a big way. then they can come back in two years or so.
since I joined web3 two years ago I've participated in the rounds. but it seems like things only get worse. gutted.
