Paywall

Problem Statement

🚨 ProblemCreators and traders constantly share valuable micro-content (insights, signals, guides), but existing monetization tools are:Web2-only (Patreon, Substack) — require fiat, subscriptions, or KYC.NFT-heavy — complex, slow, and intimidating for casual users.Off-platform — users lose engagement when redirected elsewhere.💡 SolutionPaywall brings instant Web3 micropayments directly inside social posts. A creator can post alpha, insights, or reports on X with a Paywall frame link. Followers click, connect their wallet, pay $1–$5 in crypto, and instantly unlock encrypted content — all within the same post interface.It’s frictionless, non-custodial, and Web3-native. Every payment goes directly to the creator’s wallet via smart contracts. Later, NFT passes or subscriptions can be layered for recurring access.🌍 Use CasesTraders selling “next gem” calls or alpha listsEducators posting mini-tutorials or code snippetsJournalists offering exclusive short reportsCreators selling templates, guides, or private content💰 Revenue5–10% fee on transactionsOptional paid tiers for creators (higher limits, analytics, NFT gating)Partnerships with communities (e.g., token-gated groups)🧭 VisionTo become the standard crypto micropayment layer for social platforms, empowering creators to own their earnings and audiences to own their access.
