Fees

Haven charges small fees on automated “boost” and “repay” rebalances, calculated as a percentage of the amount boosted or repaid. Practically, this means that a 2% “boost” fee, for instance, applies only to the boosted amount—not the entire position—making the actual cost significantly lower. The exact fee in USD varies based on factors like your position size and the LTV level at which the boost is applied.

Each fee percentage has been thoughtfully determined to balance fairness, support Solana’s priority fee structure during network congestion, and enable rapid rebalancing during extreme market volatility.

Boost fee

The boost fee is variable and depends on your total position size (net worth). For positions of $10K or less, the maximum fee is 2% of the boost amount, while for positions of $1M or more, the fee is 0.5%.

The greater your position size, the less your relative boost fees will be.

Repay fee

To minimize volatility decay, repays carry a flat fee of 0.25% on the repaid amount.
