Blink

Blink is a minimalist social media app built on Starknet, where users share one authentic text post daily (max 50 characters, e.g., "Rain’s loud"), minted as an NFT they own. Friends can send "vibe" tokens as micro-rewards, fostering real connections with a blockchain twist. Our mission is to empower users with ownership and simplicity.

Features

• Daily Posts: Share one unfiltered text post per day, triggered by a random prompt.
• NFT Ownership: Each post is minted as a unique NFT on Starknet, owned by the user.
• Micro: Users send micro-rewards ($0.1), with 10% fee to Blink, 90% to the poster.
• Minimal UI: Simple interface with a daily wall of posts, no feeds or edits.
• Wallet Integration: Connect via Starknet wallets (e.g., Argent) with account abstraction.

Tech Stack

• Frontend: Next.js (React framework for fast, SEO-friendly apps)
• Blockchain: Starknet (Layer 2 for low-cost NFT minting and vibe token transfers)
• Smart Contracts: Cairo (for NFT and vibe token logic)
• Wallet: Starknet.js (interfacing with wallets like Argent)
• Styling: Tailwind CSS (for rapid, minimalist design)
