What is USDAX Finance

USDAX Finance is a decentralized CDP (Collateralized Debt Position) protocol. Users deposit crypto collateral, mint USDAX (a 1:1 USD-pegged stablecoin), and repay to unlock their assets. No custodian, no credit check, no KYC. Fully on-chain on Robinhood Chain (Arbitrum Orbit, chain ID 46630).

Protocol Mechanics

  • Deposit WETH, WBTC, or stETH as collateral
  • Mint up to 75-80% LTV in USDAX against your position
  • Health Factor below 1.0 opens the position to permissionless liquidation
  • Liquidators earn a 5% bonus on seized collateral
  • Deposit USDAX into the savings module to earn 4.20% APY
  • Protocol governance via APX token (coming soon)
