Modern Treasury — design system & UI screens

Fintech · 1 screen · 9 sections · https://www.moderntreasury.com/

A platform for building payments products and financial infrastructure. This is a long-form landing page with a hero section featuring "Build Products That Move Money" as the main headline, followed by sections explaining the platform's capabilities for fiat and stablecoin payments, features for scaling from zero, and key stats like "$600 Billion" in processing volume and "99.99%" uptime. The layout uses alternating text and product screenshot sections, stat highlights, a sign-up form, and a footer with navigation and company information.

Decoded design system

Modern Treasury's decoded design system: background #FFFFFF, text #151515, accent #BAE0CF, link #BAE0CF, primary #543B4E; type scale h1 71px / h2 47px / body 14px; 8px spacing base; 2px base radius. The single interactive/action color is #BAE0CF — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Role	Value
bg	`#FFFFFF`
surface	`#F0F0F0`
border	`#DBDBDB`
text	`#151515`
text_muted	`#6D6D6D`
primary	`#543B4E`
accent	`#BAE0CF`
link	`#BAE0CF`
secondary	`#0C221D`
button_bg	`#BAE0CF`
button_text	`#151515`

Using these colors

Action color #BAE0CF — the single interactive color; only on things you click or must notice, never large fills.
accent, link, button_bg are all #BAE0CF — one role, not several (the action color).
accent #BAE0CF — 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.
primary #543B4E — a brand color — but the call-to-action uses #BAE0CF, not this.
secondary #0C221D — 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.
