At its core, Hylo is a decentralized stablecoin protocol supporting leveraged trades against its collateral. Unlike traditional stablecoins that depend on a single issuer or reserve asset, Hylo spreads its backing across multiple independent collateral pools including SOL LSTs, BTC, and USDC, leaving no single point of failure. The core challenge in crypto-backed stablecoin design is hedging the underlying collateral volatility. Hylo achieves this delta-neutral positioning through a simple core equation which splits one asset into two synthetic components:
  1. Leverage Token (xASSET): A leveraged derivative absorbing the entire price exposure of the underlying asset.
  2. Virtual Stablecoin (vUSD): A dollar-pegged stablecoin with a value of exactly $1.
vUSD are internal accounting units within Hylo’s exchange program. They are not tradeable tokens. Users interact only with hyUSD, xASSETs, and collateral.
At any time, the total value locked (TVL) for the underlying asset must equate to the sum of its vUSD and xASSET market caps. ASSET TVL=vUSD Supply⋅$1+xASSET Supply⋅xASSET Price\text{ASSET TVL} = \text{vUSD Supply} \cdot \text{\$1} + \text{xASSET Supply} \cdot \text{xASSET Price} The xASSET Price is dynamically calculated. As TVL fluctuates with the underlying asset’s market price, the xASSET component absorbs all price movement, creating structural leverage while protecting the $1 peg on vUSD. See Multi-Asset Architecture for how individual pool invariants combine to back hyUSD.
