Other charges · only triggered in specific events

Settlement, liquidation & early-exit.

Settlement fee
0.10% per side
Applies · 15d / 1mo / 1yr only

Charged at expiry — both the winner and the loser pay 0.10% of notional. Short and medium swaps (15 min → 24 h) have no settlement fee — only the entry fee at match.

Liquidation fee
2% of notional · cap
Applies · auto-close at 95% margin depletion

If your position is auto-closed at 95% margin depletion, the protocol sweeps whatever remains of your margin (max 5%), but the fee is hard-capped at 2% of notional. Anything above that cap is refunded to you.

Early-exit penalty
2% + 1% of your margin
Applies · voluntary close before expiry

2% of your margin goes to the counterparty as compensation, 1% to Verslan. Your current mark-to-market PnL is settled normally on top of the penalty.
