QR Coin operates as a decentralized auction platform where users bid USDC to display URLs on QR codes. Revenue is generated from bid creation fees (~11.11 USDC) and contribution fees (~1.00 USDC), with a portion potentially going to platform maintenance or token incentives.
Businesses can offer QR Coin bidding as a service to clients, managing auctions to secure QR code placements for campaigns. Revenue comes from service fees or markups on bids, leveraging the transparency and automation of smart contracts on Base.
Winners receive QR tokens as rewards, which could be integrated into a loyalty program or traded. Revenue can be generated by creating utility for these tokens, such as staking for discounts or access to premium features within the ecosystem.
💬 Integration Tip
Always query the current token ID first to ensure bids target the active auction, and use Bankr for seamless USDC transactions to handle gas and signing automatically.
