Mathrix

Mathrix tells you almost nothing: its website is a single page reading ALGORITHMIC TRADING with a recruiting link, the deliberate opacity of a shop that competes on strategies it would rather not discuss. Behind it sits one of the earlier institutional crypto market makers, active in digital assets for over a decade and run fully automated, with no human touching individual trades.

It quotes on both centralized and decentralized venues, an uncommon breadth given that DEX market making demands on-chain, smart-contract infrastructure most rivals skip. Headquartered in Zug, the heart of Switzerland's Crypto Valley, with desks in the Netherlands and Singapore, it stays small and flat by design.
