$QR — qrcoin.fun

Mar 2025 — present · #1 mini app on Farcaster

qrcoin.fun is a daily onchain auction for attention: the winner of each day's auction decides where the QR points for a day. I've been the lead engineer since auction #2, working with founder Jake to take it from an early prototype into the #1 mini app on Farcaster. I build the web app, the V2–V5 USDC auction smart contracts (V5 is the current production contract on Base, adding batch settlement so auctions with hundreds of bids fit inside a single block), the subgraphs and indexer, real-time bidding (Wagmi + Supabase), Privy social auth, and the airdrop/claim system. Live stats: 480+ daily auctions, $1.1M+ in bids, 3,000+ unique bidders, and $21M+ in token volume.

I am the public face, but i could never build @qrcoindotfun on my own. Here are some of our $QR contributors so far, in addition to our holders, bidders, and users, all of whose involvement is much appreciated. @thescoho is in a category of his own as lead dev since auction #2. Show more
