Free mint, 72 hours: Osero Origin NFT. Osero is stablecoin yield infrastructure with a $13.5M seed co-led by Sky Ecosystem (ex-MakerDAO) and Plasma - and it ring-fenced $10M of that raise as a risk reserve, which almost no yield protocol does. Ahead of the Osero App launch it's giving early supporters a free Origin NFT (free + gas, on Base).

No token promised - but a free marker from a serious team, minted right before launch: Osero guide
