Understanding USDXL Arbitrage

​
When USDXL Price is Above $1

When USDXL trades above its peg in the market, arbitrageurs can profit while helping stabilize the price:

​
Example Scenario

  2. USDXL market price: $1.05
  3. Arbitrage Process:
    • Mint 1000 USDXL from HypurrFi (costs $1000 in collateral value)
    • Sell 1000 USDXL on market for $1050
    • Wait for price to normalize
    • Buy 1000 USDXL at $1.00
    • Repay protocol debt
    • Profit: $50 (minus gas and interest costs)
Result: Increased market supply helps bring price back to peg

​
When USDXL Price is Below $1

When USDXL trades below its peg, borrowers are incentivized to repay their debt at a discount:

​
Example Scenario

  1. USDXL protocol price: $1.00
  2. USDXL market price: $0.95
  3. Arbitrage Process:
    • Buy 1000 USDXL from market for $950
    • Repay 1000 USDXL debt (worth $1000)
    • Net savings: $50 (minus gas costs)
Result: Decreased market supply helps drive price back up to peg
