Fee

UdonFi applies a flat 0.1% fee on specific actions to support protocol sustainability and treasury growth. These fees are transparently applied and enforced on-chain.

Only the following actions incur a fee:

Fee Breakdown

Action	What Happens	Example
Supply	No fee applied. You deposit the full amount.	You supply 100 CHR → receive 100 CHR in protocol.
Withdraw	0.1% fee deducted from the amount you withdraw.	You withdraw 100 CHR → receive 99.9 CHR, 0.1 CHR goes to UdonFi treasury.
Borrow	0.1% fee taken upfront; debt reflects full amount.	You borrow 100 CHR → receive 99.9 CHR, debt shows 100 CHR.
Repay	0.1% fee applied to what you repay. Only 99.9% of the repaid amount reduces debt.	You repay 100 CHR → only 99.9 CHR counts. To repay 100 CHR debt, send 100.01 CHR.

💡 Formula for full debt repayment:

To fully repay a debt of X, use the formula:

Repay amount = X × 100 / (100 – fee percentage)

At the current fee of 0.1%, this simplifies to:

Repay amount = X × 100 / 99.9
