+# Design System: Coinbase
+
+## 1. Visual Theme & Atmosphere
+
+Coinbase's website is a clean, trustworthy crypto platform that communicates financial reliability through a blue-and-white binary palette. The design uses Coinbase Blue (`#0052ff`) — a deep, saturated blue — as the singular brand accent against white and near-black surfaces. The proprietary font family includes CoinbaseDisplay for hero headlines, CoinbaseSans for UI text, CoinbaseText for body reading, and CoinbaseIcons for iconography — a comprehensive four-font system.
+
+The button system uses a distinctive 56px radius for pill-shaped CTAs with hover transitions to a lighter blue (`#578bfa`). The design alternates between white content sections and dark (`#0a0b0d`, `#282b31`) feature sections, creating a professional, financial-grade interface.
+
+**Key Characteristics:**
+- Coinbase Blue (`#0052ff`) as singular brand accent
+- Four-font proprietary family: Display, Sans, Text, Icons
+- 56px radius pill buttons with blue hover transition
+- Near-black (`#0a0b0d`) dark sections + white light sections
+- 1.00 line-height on display headings — ultra-tight
+- Cool gray secondary surface (`#eef0f3`) with blue tint
+- `text-transform: lowercase` on some button labels — unusual
+
+## 2. Color Palette & Roles
+
+### Primary
+- **Coinbase Blue** (`#0052ff`): Primary brand, links, CTA borders
+- **Pure White** (`#ffffff`): Primary light surface
+- **Near Black** (`#0a0b0d`): Text, dark section backgrounds
+- **Cool Gray Surface** (`#eef0f3`): Secondary button background
+
+### Interactive
+- **Hover Blue** (`#578bfa`): Button hover background
+- **Link Blue** (`#0667d0`): Secondary link color
+- **Muted Blue** (`#5b616e`): Border color at 20% opacity
+
+### Surface
+- **Dark Card** (`#282b31`): Dark button/card backgrounds
+- **Light Surface** (`rgba(247,247,247,0.88)`): Subtle surface
+
+## 3. Typography Rules
+
+### Font Families
+- **Display**: `CoinbaseDisplay` — hero headlines
+- **UI / Sans**: `CoinbaseSans` — buttons, headings, nav
+- **Body**: `CoinbaseText` — reading text
+- **Icons**: `CoinbaseIcons` — icon font
+
+### Hierarchy
+
+| Role | Font | Size | Weight | Line Height | Notes |
+|------|------|------|--------|-------------|-------|
+| Display Hero | CoinbaseDisplay | 80px | 400 | 1.00 (tight) | Maximum impact |
+| Display Secondary | CoinbaseDisplay | 64px | 400 | 1.00 | Sub-hero |
+| Display Third | CoinbaseDisplay | 52px | 400 | 1.00 | Third tier |
+| Section Heading | CoinbaseSans | 36px | 400 | 1.11 (tight) | Feature sections |
+| Card Title | CoinbaseSans | 32px | 400 | 1.13 | Card headings |
+| Feature Title | CoinbaseSans | 18px | 600 | 1.33 | Feature emphasis |
+| Body Bold | CoinbaseSans | 16px | 700 | 1.50 | Strong body |
+| Body Semibold | CoinbaseSans | 16px | 600 | 1.25 | Buttons, nav |
+| Body | CoinbaseText | 18px | 400 | 1.56 | Standard reading |
+| Body Small | CoinbaseText | 16px | 400 | 1.50 | Secondary reading |
+| Button | CoinbaseSans | 16px | 600 | 1.20 | +0.16px tracking |
+| Caption | CoinbaseSans | 14px | 600–700 | 1.50 | Metadata |
+| Small | CoinbaseSans | 13px | 600 | 1.23 | Tags |
+
+## 4. Component Stylings
+
+### Buttons
+
+**Primary Pill (56px radius)**
+- Background: `#eef0f3` or `#282b31`
+- Radius: 56px
+- Border: `1px solid` matching background
+- Hover: `#578bfa` (light blue)
+- Focus: `2px solid black` outline
+
+**Full Pill (100000px radius)**
+- Used for maximum pill shape
+
+**Blue Bordered**
+- Border: `1px solid #0052ff`
+- Background: transparent
+
+### Cards & Containers
+- Radius: 8px–40px range
+- Borders: `1px solid rgba(91,97,110,0.2)`
+
+## 5. Layout Principles
+
+### Spacing System
+- Base: 8px
+- Scale: 1px, 3px, 4px, 5px, 6px, 8px, 10px, 12px, 15px, 16px, 20px, 24px, 25px, 32px, 48px
+
+### Border Radius Scale
+- Small (4px–8px): Article links, small cards
+- Standard (12px–16px): Cards, menus
+- Large (24px–32px): Feature containers
+- XL (40px): Large buttons/containers
+- Pill (56px): Primary CTAs
+- Full (100000px): Maximum pill
+
+## 6. Depth & Elevation
+
+Minimal shadow system — depth from color contrast between dark/light sections.
+
+## 7. Do's and Don'ts
+
+### Do
+- Use Coinbase Blue (#0052ff) for primary interactive elements
+- Apply 56px radius for all CTA buttons
+- Use CoinbaseDisplay for hero headings only
+- Alternate dark (#0a0b0d) and white sections
+
+### Don't
+- Don't use the blue decoratively — it's functional only
+- Don't use sharp corners on CTAs — 56px minimum
+
+## 8. Responsive Behavior
+
+Breakpoints: 400px, 576px, 640px, 768px, 896px, 1280px, 1440px, 1600px
+
+## 9. Agent Prompt Guide
+
+### Quick Color Reference
+- Brand: Coinbase Blue (`#0052ff`)
+- Background: White (`#ffffff`)
+- Dark surface: `#0a0b0d`
+- Secondary surface: `#eef0f3`
+- Hover: `#578bfa`
+- Text: `#0a0b0d`
+
+### Example Component Prompts
+- "Create hero: white background. CoinbaseDisplay 80px, line-height 1.00. Pill CTA (#eef0f3, 56px radius). Hover: #578bfa."
+- "Build dark section: #0a0b0d background. CoinbaseDisplay 64px white text. Blue accent link (#0052ff)."

+# Coinbase Inspired Design System
+
+[DESIGN.md](https://github.com/VoltAgent/awesome-design-md/blob/main/design-md/coinbase/DESIGN.md) extracted from the public [coinbase](https://coinbase.com/) website. This is not the official design system. Colors, fonts, and spacing may not be 100% accurate. But it's a good starting point for building something similar.
+
+## Files
+
+| File | Description |
+|------|-------------|
+| `DESIGN.md` | Complete design system documentation (9 sections) |
+| `preview.html` | Interactive design token catalog (light) |

+
+Use [DESIGN.md](https://github.com/VoltAgent/awesome-design-md/blob/main/design-md/coinbase/DESIGN.md) to use as a reference for AI agents (Claude, Cursor, Stitch) to generate UI that looks like the Coinbase design language.
