Dreamprint

If you've been to many crypto events, you're probably tired of the same old T-shirts, hats, and stickers that sponsors give away for swag. For sponsors, the ROI is low too - the majority of swag is stored away in closets, never to be seen again in public.

Dreamprint fixes this with NFT polaroids—creating an experience that’s personalized, interactive, and most importantly, onchain.

Whether it’s a protocol, stablecoin, or wallet, any company can adapt polaroid prints for their own goals. Here’s how it benefits them:

• Price: for 500 pieces, Fujifilm Instax Mini film is 75% cheaper than T-Shirts
• Live UX feedback: watch people using your product, so you know how bad/good your onboarding is
• Onchain: brings users into your ecosystem
• Virality: encourage users to share on X/Farcaster, which further boosts ROI

In the future, other creative mediums can be explored so companies can adapt them to their own strengths and value prop. For example, Uniswap had trading cards at Permissionless, Farcaster gave away polaroids at Devcon, ENS printed out custom swag, etc.
