light · modern · high · custom · confidence 92% · deep decode

Uniswap swaps in Basel Grotesk at 64px on a tuned 485 weight, ink #131313 on white, with hot pink #FF37C7 12px-radius buttons as the only shout. Token grids and swap widgets float in generous whitespace — DeFi's blue-chip protocol dressing like a Swiss exchange with one neon sign.

Tokens

Uniswap's decoded design system: background #FFFFFF, text #0A0A0B, accent #FF37C7, link #FF37C7, primary #FF37C7; type scale h1 64px / h2 36px / body 16px; 8px spacing base; 4px base radius. The single interactive/action color is #FF37C7 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

# Uniswap — Design System

> light, modern, high, custom — deep decode (measured live)

Uniswap swaps in Basel Grotesk at 64px on a tuned 485 weight, ink #131313 on white, with hot pink #FF37C7 12px-radius buttons as the only shout. Token grids and swap widgets float in generous whitespace — DeFi's blue-chip protocol dressing like a Swiss exchange with one neon sign.

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#F0F0F0` |
| border | `#DADADA` |
| text | `#0A0A0B` |
| text_muted | `#676767` |
| primary | `#FF37C7` |
| accent | `#FF37C7` |
| link | `#FF37C7` |
| secondary | `#2ABDFF` |
| button_bg | `#FF37C7` |
| button_text | `#222222` |

**Using these colors**

- **Action color** `#FF37C7` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `primary`, `accent`, `link`, `button_bg` are all `#FF37C7` — one role, not several (your action color).
- **accent** `#FF37C7` — THE accent / action color — interactive & must-notice only (buttons, links, focus, one key highlight); never large fills or backgrounds. Scarcity is what makes it read as designed.
- **secondary** `#2ABDFF` — optional secondary accent — LOW decode confidence; use rarely (a status color or a single decorative moment) or omit it entirely. Prefer one accent unless the reference clearly shows two.
- **Page coverage** (full-page screenshot pixels): `#FDFDFD` 92.8% · `#CCC7D2` 7.2%

## Typography

- Heading: **Basel Grotesk** _(free fallback: Newsreader)_
- Body: **Basel Grotesk** _(free fallback: Newsreader)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 64px / 485 · lh 76px |
| h2 | 52px / 485 · lh 50px |
| h3 | 36px / 485 · lh 40px |
| body | 24px / 485 · lh 29px |
| small | 18px / 535 · lh 21px |

- Weight ladder: 485 · 535 — use these exact measured weights, not the 400/600 defaults.

> **Fonts —** Basel Grotesk may be proprietary — safe free fallback: Newsreader (Google Fonts).

## Spacing
- base unit: 8px (inferred from the measured scale)
- measured scale: 2px, 4px, 5px, 6px, 8px, 12px, 16px, 20px, 24px, 32px — snap all gaps/padding to these

## Radius
- base: 4px
- button: 9999px
- card: 20px
- pill: 9999px
- sharp: 3px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#FF37C7` / `#000000` | 1px solid rgba(0, 0, 0, 0) | 12px | 8px 12px 8px 12px | 400 13.3333px | color(srgb 0.0745098 0.0745098 0.0745098 / 0.00313726) 0px 0px 10px 0px |
| secondary | `rgba(0, 0, 0, 0)` / `#FF37C7` | none | 20px | 0px 0px 0px 0px | 485 16px | none |

**States (measured, not guessed)**

- primary hover: background `#E500A5`
- primary focus: outline `1px auto rgba(0, 0, 0, 0)`
- transition: `transform 0.1s cubic-bezier(0.17, 0.67, 0.45, 1)`

## Shadows (elevation)
- card: `color(srgb 0.0745098 0.0745098 0.0745098 / 0.00313726) 0px 0px 10px 0px`
- button: `color(srgb 0.0745098 0.0745098 0.0745098 / 0.00313726) 0px 0px 10px 0px`

## Motion
- durations: 100ms (dominant) · 400ms · 80ms
- easings: `ease-in-out` (dominant) · `cubic-bezier(0.34, 1.56, 0.64, 1)`
- animated properties: opacity, transform, background-color, fill

Micro-interactions use the dominant duration + easing; nothing on the page animates slower than the longest duration above — don't invent springier motion.

## Layout (measured)
- nav: 72px

## Motion choreography (measured)
Load order: `div`×28 @0ms → `div._textDecoration-_platfor`×2 @1ms → `div._display-flex`×2 @1ms → `div` @1ms → `div`×44 @1ms → `span.sc-gLaqbQ`×6 @5ms
- `span.sc-gLaqbQ` ×3 — opacity 0→1 · transform translateY(100px)→translateY(0px) — 1000ms cubic-bezier(0.19, 1, 0.22, 1)
- `span.sc-ipUnzB` ×2 — opacity 0→1 · transform translateY(100px)→translateY(0px) — 1000ms cubic-bezier(0.19, 1, 0.22, 1) (delay 300ms)
- `div._position-_platformweb_a` ×13 — transform rotate(-22deg)→rotate(22deg) — 4762ms ease-in-out · loops
- stagger: `span` ×5 — 100ms apart
- scroll reveal: 2 elements rest at opacity 0, animate in over 1000ms (0 revealed during the drive).
- overlay dialog (auto-opened): panel rgba(0, 0, 0, 0) · r 0px
  - exit: opacity from 1 · 100ms cubic-bezier(0.17, 0.67, 0.45, 1) | transform from scale(1) · 100ms cubic-bezier(0.17, 0.67, 0.45, 1)

Rebuild the timeline, not just the durations — order, delays and staggers above are the choreography.

## Components (measured)
- input: h 43.1875px · r 0px · bg rgba(0, 0, 0, 0) · placeholder rgba(19, 19, 19, 0.35)

## Themes (both measured)
- dark counterpart: bg `#131313` · text `#FFFFFF`

## Responsive (measured)
- breakpoints: 450px · 480px · 640px · 768px · 1024px · 1280px
- mobile (390px): hero 36px · body 16px · nav: inline

## How to apply
Paste the Tailwind `@theme` (or CSS variables) as your base, then build each
section to its spec — verify every color, radius, and font against these tokens.
Hover/focus states, shadows and motion timings above are measured from the live page — match them exactly, don't re-guess them.
