🐣PnL Fee Model

The Profit Fee is the protocol’s core revenue driver and its main protective moat against manipulation.

How it works:

Period
PnL Fee % (Base)

0–2 min (lock)

100%

2–8 min

Drops sharply to 70%/80%/85% based on user tier level

8 min–8 hrs

Linear drop to 25%

After 8 hrs

Fixed at 25%

Detailed logic:

  • 100% fee for 0–2 min: You can’t close the position to prevent S price manipulation.

  • After unlock: Fee drops sharply based on your staking tier:

    • No staking: 85%

    • Tier 1 staker: 80%

    • Tier 2 staker: 75%

    • Tier 3 staker: 70%

    • Tier 4 staker: 65%

  • Over the next 7 hours, 58 minutes, the PnL fee linearly decreases to a minimum of 25%.

  • Once you hit 8 hours, the fee stays fixed at 25% untill the position is closed or liquidated.

The PnL fee is always charged on the entire position size: (collateral + unrealized profit + leveraged exposure).

Example:

  • You deposit 10 Sonic with 500x leverage, so your position size is 5,000 Sonic.

  • The price moves up 20%, so your unrealized profit is 1,000 Sonic.

  • Your total position size for the fee is 10 (collateral) + 1,000 (profit) + 5,000 (exposure) = 6,010 Sonic.

  • If you close after 10 minutes, your PnL fee is about 68%, so you pay ~4,087 Sonic in fees.

  • Your net would be 1,923 Sonic, but the profit cap is 50x collateral, so you will be paid 500 Sonic max.

  • Net profit is 490 Sonic.

Congrats, you've just did a 49x! Not bad for a rookie!

Thing to keep in mind:

  • PnL fee drops to minimum of 25% after ~8 hours.

  • But after 8 hours, you start paying funding at 0.25% per hour on the same total size.
