the onchain attention machine

The problem $QR solves

Attention is upstream of everything. For builders without distribution, the first problem they need to solve is how they can drive attention to their project. $QR solves this problem for builders. Builders can bid to win one of our daily onchain auctions to drive thousands of crypto-natives to check out their project in 24 hours.

On the other side of that, our users get paid to discover something new onchain every day. We offer $QR micropayments just for checking out the winning link. Tens of thousands of users have earned hundreds of thousands of micropayments in 50 days since we started doing this. It's a simple, fast, and easy way to earn a little crypto every day and stay on top of what's new onchain.

Challenges we ran into

Our primary challenge was no different than the one most builders face, as described above. In order to be able to drive significant attention to our daily auction winners, we needed to first find a way to drive attention to our project in the first place. We began by compounding some attention through sheer persistence, hard work, and determination, shipping new features and tweeting and casting daily to drive attention to our daily auctions and our winners. This included long-form write-ups on our daily auction winners every day, including weekends and holidays. We scraped and clawed to drive as much attention as we could to our daily winners.

Then, after about 75 days, we achieved our first major milestone in our ability to systematically drive serious attention to our daily winners. The key was leveraging Farcaster mini app notification distribution combined with micropayments on Base. We were able to get thousands (now tens of thousands) of people to download our mini app on Farcaster. We then started sending them once daily notifications offering $QR micropayments as micro-incentives to check out the winning link each day. We've since scaled this strategy on Farcaster and implemented the same flow on our website (requiring sign-in with X). We'll also have this on TBA from day one.
