😩 The problem
Unbanked farmers in Sub-Saharan Africa rely on cash or slow, expensive remittance services that require internet access. Existing Bitcoin wallets assume connectivity, leaving a critical gap for offline users who still need secure, fast transactions.
🎯 First customer
A 45-year-old smallholder farmer in rural Kenya with a basic feature phone and no bank account.
🛠️ Smallest version to build
- → Identify 50 farmers willing to test SMS-based wallet setup
- → Distribute printed QR codes for wallet addresses via local cooperatives
- → Collect feedback on transaction signing via SMS during a 2-week pilot
- → Measure success by number of completed remittances without internet
💰 How it makes money
Charge a 1% fee on remittances processed, capped at $0.50 per transaction.
🚩 Where it could fail
- → Low adoption due to distrust in digital payments among farmers
- → Regulatory hurdles from local financial authorities on crypto usage
- → SMS-based signing proves too slow or error-prone for users
🧪 First step this week
Visit 3 local farming cooperatives this week to pitch the idea and recruit 10 farmers for a verbal agreement to participate in a pilot.

# Build A Production-Grade Landing Page For This Startup Idea ## Idea > "A startup that provides offline-first Bitcoin wallets with SMS-based transaction signing for unbanked farmers in Sub-Saharan Africa — enabling remittances without internet access" ## Context - Treat this as a real Crypto / Web3 company launching today, not a loose concept. - Derive a strong, brandable product name from the idea and use it consistently across the page. - Define the most likely target user, their trigger moment, the pain they already feel, and the clearest paid offer. - Keep the strategy, copy, and visuals specific to this idea. Avoid generic AI SaaS language or template copy. ## Repo Context - Before coding, inspect the repo root for `CLAUDE.md` and follow it if present. - Then inspect shared project docs that are clearly relevant, such as README files, design-system docs, inspiration references, or files explicitly referenced by `CLAUDE.md`. - If the selected agent file or shared project docs reference `SKILL.md`, skill folders, or inspiration docs, read the relevant ones before implementation. - Do not merge rules from other agent-specific root files unless the selected agent file or project docs explicitly point to them. - Do not ignore repo instructions. Only create a missing agent-context file if the project clearly uses that pattern and a minimal file would materially improve future consistency. ## Execution Constraints - Build for Claude Code. - Work inside the existing repo conventions and current stack instead of introducing a new setup. - Framework fit: Match the existing route, rendering, and styling conventions, and keep interactivity isolated to places that actually need it. - Return production-ready code — no partial snippets or pseudo-code. - Make strong, opinionated design decisions. - Write specific, benefit-driven copy — no placeholders. - If the repo includes `CLAUDE.md`, treat it as project-specific context and follow it. - Return production-ready code only. No pseudo-code, placeholders, or partial sections. ## Before Coding, Explicitly Define ### 1. Visual Thesis - One sentence on mood, material feel, and energy. ### 2. Content Plan - Hero: brand + bold promise - Context / Why Now: why this matters now - Problem / Solution: 3 pains and how the product resolves them - Feature Detail: 4-6 features with concrete benefits - Social Proof: 2 testimonials + 3 trust stats - Pricing / Offer: the most credible monetization model for this product - FAQ: 5 real objections - Final CTA: direct close with clear next step ### 3. Interaction Thesis - Use exactly 2-3 intentional motions. - Motion must support hierarchy or product presence, not decoration. - Respect prefers-reduced-motion. ### 4. Accessibility Notes - Semantic HTML, correct headings and landmarks, visible focus states, keyboard support, meaningful alt text, and WCAG 2.2 AA contrast. ### 5. Design System - Exact font family decision: choose the best headline font and the best body/UI font for this idea, explain why they fit the brand, and use no more than 2 typefaces total. - Exact theme colors: define concrete theme tokens for background, surface, text, muted text, border, accent, and accent-foreground. - Keep the palette disciplined: mostly neutrals plus 1 accent color. Do not use 4-5 competing colors or a messy gradient-heavy scheme. - Typography scale with sizes and weights. - Spacing scale using a 4px rhythm. - CSS variables or design tokens. - Borders, shadows, and radii. ### 6. Precision Audit - Define the visual quality bar for spacing, alignment, card sizing, button sizing, and section balance before implementation. - The page must feel pixel-perfect, measured, and clean rather than approximate. ### 7. Visual Archetype - Derive a specific visual archetype from the idea itself, not just the category. - Use that archetype to drive font pairing, theme colors, spacing density, hero composition, product imagery, and section emphasis. ## Idea-Specific Direction - Audience angle: Write for users who value transparency, control, and speed, but avoid hype-heavy crypto language. - Product surface: Favor data-rich wallet, transaction, community, or protocol surfaces if they fit the idea. - Visual direction: Use a sharp, technical visual language with restrained accent use and trust-first clarity. - Theme discipline: Use deep or mineral neutrals with one sharp accent. Choose angular, technical sans families and keep the color system controlled so the product feels trustworthy rather than noisy. - Offer model: Prefer a credible offer like free + pro analytics, usage tiers, or access-based plans if monetization fits. - Proof to emphasize: Use trust signals such as assets monitored, transactions analyzed, communities onboarded, or latency/security claims only when believable. ## Visual Archetype - Archetype: Trust-Centric Utility - Why it fits: The product touches money, risk, or sensitive behavior, so the page should feel controlled, trustworthy, and highly legible. - Typography direction: Use premium, restrained sans-serif fonts that feel credible, stable, and calm. - Color mood: Use deep neutrals or mineral tones with one confident accent that supports trust rather than excitement. - Layout behavior: Use a structured, highly balanced layout with clear proof, reassurance, and scanning efficiency. - Product visualization: Show product states, savings summaries, transaction flows, alerts, or comparison views instead of decorative concept art. - Motion behavior: Keep motion extremely restrained and functional, focused on hierarchy and feedback. - Section emphasis: Put extra emphasis on credibility signals, reassurance, proof, and objections around safety or accuracy. ## Page Requirements ### 1. Hero - Create a sharp product name derived from the idea. - Write a headline with a clear value proposition and a supporting subheadline that explains who it is for and why it matters now. - Include one primary CTA and one lower-friction secondary CTA. - Make the first viewport feel like one unified composition. - Brand first. The page should still feel distinctive even without the nav. - Do not use a generic hero card unless the product UI itself is the primary interaction. ### 2. Context / Why Now - Explain the market shift, behavioral change, or user frustration that makes this product relevant right now. - Add 2-3 short proof points, stats, or credibility signals that feel plausible for this idea. ### 3. Problem / Solution - Surface 3 concrete pain points the target customer already feels. - Explain exactly how this product solves them better than the status quo. ### 4. Feature Detail - Create 4-6 features. - For each feature, include a name, one short benefit-driven description, and a suggested Lucide icon. ### 5. Social Proof - Write 2 realistic testimonials with name, role, company, and a quote that sounds specific rather than generic. - Add 3 stats that support trust or momentum. ### 6. Pricing / Offer - Choose a pricing or offer structure that fits the category and buying motion. - Use 3 tiers or an equally clear offer structure if that is more credible. - Mark one option as the recommended choice. ### 7. FAQ - Answer 5 real objections with short, confident responses. ### 8. Final CTA - End with a clear closing headline, one sentence of support copy, and a direct CTA. ## Copy Rules - Lead with the outcome, not the feature list. - Use specific, benefit-driven copy written for the likely buyer. - Keep sections concise, scannable, and commercially sharp. - Avoid placeholders, vague buzzwords, and filler text. ## UI Rules - Use a calm, premium hierarchy with strong contrast and restrained accent use. - Prefer border-led surfaces, subtle radii, and crisp typography over flashy effects. - The theme must feel aesthetic and professional, not colorful for the sake of being colorful. - Choose font families that fit the product story. Do not default to generic fonts unless they are clearly the strongest choice. - Two ideas in the same category should still be allowed to look meaningfully different if their promise, audience, or emotional tone differs. - Keep the palette tight: neutrals plus one accent is the default. - Make spacing feel exact. Audit every gap, padding, margin, and max-width so the layout feels deliberate rather than loose. - If the design uses cards, make card heights, padding, border treatment, icon sizing, and headline rhythm feel consistent and balanced. - Avoid floppy sections, oversized UI, weak alignment, and random whitespace. - Push toward a pixel-perfect result on both desktop and mobile. - Keep the component structure clean and manageable for a solo developer. - Avoid over-engineering or unnecessary folders. - Make the layout excellent on desktop and mobile. ## SEO Metadata - Provide a page title under 60 characters. - Provide a meta description under 155 characters. - Provide descriptive OG image alt text. ## Delivery - Return the full implementation, not a partial snippet or a planning document. - Make the result specific enough that it can be generated well in one pass. ## Design QA Checklist - Confirm the first viewport reads as one unified composition and the brand is visually dominant. - Confirm the font pairing fits the idea, feels intentional, and does not fall back to generic defaults without reason. - Confirm the theme stays disciplined: mostly neutrals plus one accent, with clean contrast and no messy extra colors. - Confirm spacing follows a consistent 4px rhythm and section spacing feels deliberate rather than loose. - Confirm any cards use balanced heights, padding, icon sizing, border treatment, and headline rhythm. - Confirm buttons, inputs, badges, and nav elements feel proportionate and not oversized. - Confirm desktop and mobile layouts both feel polished, aligned, and visually calm. - Confirm motion is minimal, purposeful, and respects prefers-reduced-motion. - Confirm there are no placeholders, weak copy blocks, awkward gaps, or sloppy alignment. - If any item fails, refine the implementation before stopping.
