HypurrFi Protocol Overview

​

HypurrFi Product Suite

​

Lending / DeFi Products

• HypurrFi Markets (Euler V2 / community name: Mewler) — umbrella for the Euler-based isolated lending stack:
  • HypurrFi Prime — isolated lending markets with one risk profile / asset range
  • HypurrFi Yield — isolated lending markets with a different risk profile / asset range
  • Both work identically (same Euler V2 vault technology), just configured with different risk parameters and asset pairs
• Earn Vaults (Euler Earn) — curated, managed lending strategies. Users deposit and a curator routes funds to Prime or Yield markets based on yield and risk tolerance. Not the same as “vaults” in Euler terminology (where every lending market is called a vault).
• Pooled Markets (Aave V3.0.2) — shared-pool lending with combined collateral. Users deposit multiple assets as combined collateral and borrow from a shared liquidity pool.
• Legacy Isolated Markets (Fraxlend) — deprecated. No incentives, no new borrows. Only repay and withdraw. Markets remain live while assets are deposited.
• USDXL — Hyperliquid-native CDP-hybrid synthetic dollar. Backed by debt positions in Pooled Markets plus a USDT0 reserve in a hybrid model. Mintable as a CDP from Pooled Markets or directly with USDT0. USDXL is not a stablecoin.

​

Other Products

• Swype Credit Card (swype.fun) — spend against on-chain lending positions without selling assets
• Purrps (alpha) — HypurrFi DEX using Hyperliquid builder codes with integrated lending and spend
• Listing Service — asset listing service for HypurrFi markets
• HyperScan.com — Hyperliquid EVM blockchain explorer, maintained by HypurrFi as a public good

​

Network Information

• Network: HyperEVM Mainnet
• Block Explorers: hyperscan.com, hyperevmscan.io
• Native Token: HYPE (0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE for balance queries)
• Wrapped Native: WHYPE (query via WrappedTokenGatewayV3.getWHYPEAddress())

​

Querying Prices (Pooled Markets)

const ORACLE_ADDRESS = "0x9BE2ac1ff80950DCeb816842834930887249d9A8";
const oracleABI = [
  "function getAssetPrice(address asset) external view returns (uint256)",
  "function getAssetsPrices(address[] calldata assets) external view returns (uint256[] memory)",
  "function getSourceOfAsset(address asset) external view returns (address)",
];
const oracle = new ethers.Contract(ORACLE_ADDRESS, oracleABI, provider);

// Single asset price (in BASE_CURRENCY wei)
const price = await oracle.getAssetPrice(assetAddress);

// Multiple asset prices
const prices = await oracle.getAssetsPrices([asset1, asset2]);

​

Common Token Addresses (HyperEVM)

• HYPE (native): 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE
• WHYPE (wrapped): query via WrappedTokenGatewayV3
• USDT0: check Pooled Markets reserve list
• USDC: check Pooled Markets reserve list
• USDXL: check Pooled Markets reserve list
• wstHYPE, kHYPE, beHYPE: check Pooled Markets reserve list or E-Mode categories

const pool = new ethers.Contract(POOL_ADDRESS, poolABI, provider);
const reserves = await pool.getReservesList();

​
