Sovereign-grade infrastructure. Quiet confidence.
Interstellar speaks as an institutional infrastructure provider, not a startup. Numbers carry the proof; the copy does not oversell. Full sentences, title-case headings, restrained superlatives, generous white space.
Logo system
One mark — the helmet with its constellation — and one wordmark, in lockups for every context. Download the PNG for the background you are placing it on.
The default logo. Helmet mark plus wordmark in navy ink and light teal. Use on cream and white backgrounds.
interstellar-wordmark-duotone.png ↓
Mark above wordmark, for square formats, covers and social avatars where the horizontal lockup is too wide.
interstellar-stacked-duotone.png ↓
Neutral grey wordmark with the round app icon. Use where the duotone would compete with other brands, such as partner logo walls.
interstellar-wordmark-grey.png ↓
Single-colour black wordmark for print, engraving and one-colour reproduction.
interstellar-wordmark-black.png ↓
The mark alone, in white, for navy and photographic backgrounds, favicons and watermarks.
interstellar-mark-white.png ↓
The mark with its constellation of stars, in white, for dark backgrounds.
interstellar-mark-stars-white.png ↓
Round app badge above a light wordmark, for dark backgrounds, patches and merchandise.

Keep a margin equal to the height of the helmet mark on every side of the logo. Nothing — text, imagery, other logos — enters that space.
Horizontal wordmark no smaller than 120 px wide on screen or 30 mm in print; the mark alone no smaller than 24 px or 8 mm.
Duotone and grey lockups on cream or white. White mark and light badge on Navy Ink, Deep Space or photography with a dark overlay. Never on Brand Sky.
Recolour, stretch, rotate, add effects or outlines, place in a shape it did not come in, or separate the stars from the helmet.
Use the grey wordmark at the same visual weight as neighbouring logos. Interstellar never appears larger than a partner on a shared wall.
Separate Interstellar from a partner logo with a hairline rule in #CFE0E8 and equal clear space on both sides.
Colour
Navy on cream and cream on navy both pass accessible contrast. Keep Teal Ink for short labels, not paragraphs. No gradients, no textures.

Status
Typography
| Role | Typeface | Rules |
|---|---|---|
| Headings | Lexend | Weights 400–600. Title case for page and section titles; never all-caps for titles. |
| Body | Source Sans 3 | Regular 400 for paragraphs, semibold 600 for labels and buttons. 16–18 px, line-height 1.5–1.7. |
| Numbers | Lexend, tabular figures | Big navy number with a small grey caption is a signature device. Use tabular numerals in every stat and table. |
| Eyebrows | Source Sans 3, 13 px, letter-spaced caps | Short labels in Teal Ink above headings. Never for body text. |
Both families are open-source Google Fonts. Presentations built before the website used Lexend or Outfit with Inter; the website standardises on Lexend with Source Sans 3.
Voice & language
Do
- Lead with what is live and measurable: currencies, countries, participants, settlement time.
- Name the operator’s control: keys, data and operations stay with the institution.
- Write full sentences and use title case for headings.
- Say "built with PAPSS and Afreximbank" when referring to PACM.
Don’t
- Do not describe Interstellar as a startup, a crypto company or a disruptor.
- Do not use superlatives without a number behind them.
- Do not call the ledger a "blockchain network" in regulatory contexts; it is a permissioned distributed ledger.
- Do not abbreviate Universal Wallet Infrastructure to UWI on first mention.
