What We're Building

Multi Asset Margin for Hyperliquid. Giving users the ability to post variable forms of collateral, instead of selling collateral for USDC and depositing to Hyperliquid. Multi asset margin comprises of over 86% of accounts in Crypto.

What Is Hyperliquid.xyz

Hyperliquid is the fastest growing crypto derivatives exchange which is a 20-30B a year revenue sector. Currently around 6% of global market share. Hyperliquid has annualised revenues of over $1B in USDC, at 99% net margin.

How We're Building It

Blockchain under the hood, users will post collateral on our systems and we'll extend USDC collateral on venues of their choice. We will bring the venues to the user, as opposed to the user having to go to other venues.
