Modern Treasury moves money in Neue Haas Grotesk: Display cut at 71px on a precise 450 weight ('Build Products That Move Money'), Text cut at 16px, JetBrains Mono for the ledger data, and near-square 2px-radius buttons. Payment-flow diagrams in banker's neutrals complete it — fintech infrastructure typeset like the Swiss ledger it wants to be.

Tokens

Modern Treasury's decoded design system: background #FFFFFF, text #151515, accent #BAE0CF, link #BAE0CF, primary #543B4E; type scale h1 71px / h2 47px / body 14px; 4px 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.
