{"id":"hylo-usd-hyusd","title":"Hylo USD (hyUSD)","content":"**Hylo USD (hyUSD)** is a decentralized, crypto-backed [stablecoin](https://iq.wiki/wiki/stablecoin) pegged to the U.S. dollar that operates on the [Solana](https://iq.wiki/wiki/solana) [blockchain](https://iq.wiki/wiki/blockchain). It is designed to be overcollateralized by a basket of yield-bearing Solana Liquid Staking Tokens (LSTs) and is a core component of the Hylo protocol's dual-token system.\n\n## Overview\n\nHylo USD is the [stablecoin](https://iq.wiki/wiki/stablecoin) issued by the [Hylo protocol](https://iq.wiki/wiki/hylo-protocol), a [decentralized finance](https://iq.wiki/wiki/defi) (DeFi) platform built to create what it terms \"DeFi Native Money\" on [Solana](https://iq.wiki/wiki/solana). The protocol's primary function is to issue and manage hyUSD, which aims to maintain a stable 1:1 peg with the U.S. dollar without relying on traditional financial infrastructure, fiat collateral, or centralized custodians. The system is designed to be autonomous, [permissionless](https://iq.wiki/wiki/permissionless), and self-contained, utilizing on-chain assets for its backing. [\\[1\\]](#cite-id-213IqmLnBY) [\\[2\\]](#cite-id-PcmS7GgkvC)\n\nThe stability of hyUSD is maintained through a symbiotic relationship with a secondary, volatile token called xSOL. Within the Hylo ecosystem, xSOL is engineered to absorb the price fluctuations of the underlying LST [collateral](https://iq.wiki/wiki/collateral) pool. This mechanism is intended to insulate hyUSD from market volatility, ensuring its peg remains stable. In return for bearing this risk, xSOL holders receive leveraged exposure to the price of [SOL](https://iq.wiki/wiki/solana-sol). The protocol also features a yield-generation component through a Stability Pool, where users can stake hyUSD to earn rewards derived from the protocol's LST [collateral](https://iq.wiki/wiki/collateral) and fees. [\\[3\\]](#cite-id-Q1xTAb3PU5) [\\[4\\]](#cite-id-fE7Ixihb3t)\n\nThe project positions itself as a decentralized alternative to centralized stablecoins like [USDC](https://iq.wiki/wiki/usdc) and [USDT](https://iq.wiki/wiki/tether) by eliminating custodial risk and potential censorship. Its design principles emphasize on-chain transparency, guaranteed liquidity through its internal mint and redeem functions, and financially incentivized risk management. The protocol has undergone security audits and provides a public risk dashboard to monitor its health in real-time. [\\[5\\]](#cite-id-o1bxFL8gwk)\n\n> \"We do not rely on real world assets for \\[collateral] - (https://iq.wiki/wiki/collateral), instead using LSTs as 'on chain bonds' to harness network yield.\" [\\[1\\]](#cite-id-213IqmLnBY)\n\n> \"Our protocol is autonomous and self-contained. Hylo has no fund manager, third party trading dependencies, or trust gaps.\" [\\[1\\]](#cite-id-213IqmLnBY)\n\n## History\n\nThe [Hylo protocol](https://iq.wiki/wiki/hylo-protocol) underwent a smart contract security audit conducted by the firm OtterSec in May 2025, a key step before its public-facing operations gained traction. [\\[4\\]](#cite-id-fE7Ixihb3t) To incentivize user engagement and bootstrap liquidity, the project launched a points program in July 2025. This program was designed to reward users for various interactions with the protocol, such as holding xSOL or referring new users. [\\[5\\]](#cite-id-o1bxFL8gwk)\n\nOn August 7, 2025, Hylo announced that it had successfully closed a $1.5 million seed funding round. The round was led by [Robot Ventures](https://iq.wiki/wiki/robot-ventures), with participation from other notable investors including Colosseum, [Solana](https://iq.wiki/wiki/solana) Ventures, and YTWO Ventures. This funding was intended to support the continued development and expansion of the Hylo ecosystem on the Solana network. [\\[6\\]](#cite-id-AHBWtw9S0e) [\\[2\\]](#cite-id-PcmS7GgkvC) By August 12, 2025, the protocol had reportedly attracted over 2,800 active users and secured millions of dollars in [total value locked](https://iq.wiki/wiki/tvl) (TVL). [\\[4\\]](#cite-id-fE7Ixihb3t)\n\n## Technology\n\nThe Hylo protocol's architecture is centered around a dual-token system, a specific collateralization [strategy](https://iq.wiki/wiki/strategy), and interconnected products designed to maintain stability and provide utility for different risk appetites.\n\n### Dual-Token System\n\nThe core of Hylo's stability mechanism is the interaction between its two native tokens, hyUSD and xSOL, which are both issued from a single, shared [collateral](https://iq.wiki/wiki/collateral) pool.\n\n* **hyUSD**: The protocol's [stablecoin](https://iq.wiki/wiki/stablecoin), algorithmically pegged to $1 USD. Its primary function is to serve as a [stable](https://iq.wiki/wiki/stable) medium of exchange and store of value within the [Solana](https://iq.wiki/wiki/solana) DeFi ecosystem.\n* **xSOL**: A volatile token that represents a tokenized, liquidation-free leveraged long position on SOL. Its main role within the protocol is to act as a financial buffer, absorbing the price volatility of the underlying SOL LST [collateral](https://iq.wiki/wiki/collateral) to protect the hyUSD peg.\n\nThis symbiotic design ensures that as the value of the [collateral](https://iq.wiki/wiki/collateral) pool fluctuates, the [market capitalization](https://iq.wiki/wiki/market-capitalization) of xSOL adjusts accordingly, while the value of hyUSD remains [stable](https://iq.wiki/wiki/stable). [\\[3\\]](#cite-id-Q1xTAb3PU5)\n\n### Collateralization\n\nhyUSD is fully backed and overcollateralized by a diversified basket of yield-bearing [Solana](https://iq.wiki/wiki/solana) Liquid Staking Tokens (LSTs). Users can mint hyUSD by depositing accepted collateral, such as [USDC](https://iq.wiki/wiki/usdc), [USDT](https://iq.wiki/wiki/tether), [SOL](https://iq.wiki/wiki/solana), or various LSTs, which the protocol then converts into a managed pool of LSTs. At one point in its operation, the [collateral](https://iq.wiki/wiki/collateral) pool consisted entirely of [JitoSOL](https://iq.wiki/wiki/jito-staked-sol-jitosol). The protocol explicitly avoids the use of [Real World Assets](https://iq.wiki/wiki/real-world-assets-rwas) (RWAs), relying solely on on-chain crypto assets for its backing. The supported LSTs have included [mSOL](https://iq.wiki/wiki/marinade-staked-sol-msol), jitoSOL, [bSOL](https://iq.wiki/wiki/bybit-staked-sol), and [JupSOL](https://iq.wiki/wiki/jupiter-staked-sol-jupsol). [\\[4\\]](#cite-id-fE7Ixihb3t) [\\[5\\]](#cite-id-o1bxFL8gwk)\n\n### Stability Mechanism\n\nThe protocol employs several mechanisms to maintain the hyUSD peg and ensure system solvency.\n\n#### The Hylo Invariant\n\nThe relationship between the [collateral](https://iq.wiki/wiki/collateral) and the two tokens is governed by a core mathematical principle, the Hylo Invariant. This equation dictates that the total value of the collateral pool must always equal the combined [market capitalization](https://iq.wiki/wiki/market-capitalization) of all circulating hyUSD and xSOL.\n`Collateral TVL = (hyUSD Supply × hyUSD Price) + (xSOL Supply × xSOL Price)`\nSince the price of hyUSD is fixed at $1 within the protocol, any change in the [Collateral](https://iq.wiki/wiki/collateral) TVL directly impacts the price of xSOL. [\\[3\\]](#cite-id-Q1xTAb3PU5)\n\n#### Pricing and Arbitrage\n\nHylo operates as an oracle-free system, meaning it does not rely on external price feeds to value its [collateral](https://iq.wiki/wiki/collateral) or maintain its peg, which reduces the risk of price manipulation attacks. The protocol guarantees that hyUSD can always be minted or redeemed for $1 worth of collateral directly from the system with zero [slippage](https://iq.wiki/wiki/slippage). This internal mechanism creates a powerful [arbitrage](https://iq.wiki/wiki/arbitrage) opportunity. If the price of hyUSD on an external exchange deviates from $1, arbitrageurs are incentivized to buy it cheaply and redeem it with the protocol for $1 of collateral, or mint it for $1 and sell it on the market for a premium, thereby pushing the price back toward its peg. [\\[4\\]](#cite-id-fE7Ixihb3t)\n\n#### Volatility Absorption\n\nThe price of xSOL is dynamically calculated based on the value remaining in the [collateral](https://iq.wiki/wiki/collateral) pool after accounting for the backing of all circulating hyUSD. The formula is:\n`xSOL Price = (Collateral TVL - hyUSD Supply) / xSOL Supply`\nThis design ensures that when the [collateral](https://iq.wiki/wiki/collateral) value increases, the excess value accrues entirely to xSOL holders, amplifying their gains. Conversely, when the [collateral](https://iq.wiki/wiki/collateral) value decreases, the loss is absorbed by the market [cap](https://iq.wiki/wiki/cap) of xSOL, shielding hyUSD holders from the downside. [\\[3\\]](#cite-id-Q1xTAb3PU5)\n\n### Key Products\n\nThe protocol offers three distinct products catering to different user needs.\n\n* **hyUSD**: The primary [stablecoin](https://iq.wiki/wiki/stablecoin) product for users seeking a decentralized, dollar-pegged asset.\n* **xSOL**: The leveraged token for users who want to speculate on the price of SOL with no risk of [liquidation](https://iq.wiki/wiki/liquidation), margin calls, or funding rates. Its effective [leverage](https://iq.wiki/wiki/leverage) is dynamic and can be calculated as: `Effective Leverage = Collateral TVL / xSOL Market Cap`.\n* **Staked hyUSD (sHYUSD) and the Stability Pool**: The Stability Pool is the protocol's primary yield-generation engine and a secondary insurance layer. Users can deposit their hyUSD into the pool to receive sHYUSD. In return, they earn yield generated from the [staking](https://iq.wiki/wiki/staking) rewards of the underlying LST [collateral](https://iq.wiki/wiki/collateral), protocol fees, and risk premiums. As of July 2025, the stated yield was approximately 18%. However, these deposits act as a backstop; in a severe market crash where the xSOL buffer is depleted, sHYUSD is programmatically converted into xSOL to recapitalize the system, exposing stakers to potential principal loss. [\\[5\\]](#cite-id-o1bxFL8gwk) [\\[4\\]](#cite-id-fE7Ixihb3t)\n\n## Tokenomics\n\nAs of November 15, 2025, Hylo USD (HYUSD) had a [market capitalization](https://iq.wiki/wiki/market-capitalization) of approximately $35.1 million and a circulating supply of around 35.1 million tokens. The token's 24-hour trading volume was approximately $1.18 million. The maximum supply of hyUSD is uncapped, as new tokens can be minted whenever users deposit sufficient [collateral](https://iq.wiki/wiki/collateral).\n\nKey market data for hyUSD includes:\n\n* **All-Time High:** $1.01 (November 3, 2025)\n* **All-Time Low:** $0.9862 (October 10, 2025)\n* **Solana Contract Address:** `5YMkXAYccHSGnHn9nob9xEvv6Pvka9DZWH7nTbotTu9E`\n\nHylo USD is primarily traded on [decentralized exchanges](https://iq.wiki/wiki/decentralized-exchange) (DEXs) within the [Solana](https://iq.wiki/wiki/solana) ecosystem, with the most active trading pairs being against [USDC](https://iq.wiki/wiki/usdc) on platforms such as Orca and [Meteora](https://iq.wiki/wiki/joshua-meng-joshua-meteora). [\\[7\\]](#cite-id-dBA6unoggD)\n\n## Investors\n\nHylo is backed by several venture capital firms that participated in its $1.5 million seed round in August 2025. The lead investor was [Robot Ventures](https://iq.wiki/wiki/robot-ventures). Other participating investors include Colosseum, [Solana](https://iq.wiki/wiki/solana) Ventures, and YTWO Ventures.
