Fees

Trilobyte charges two types of fees to sustain the protocol and incentivise responsible management.

Protocol Fee

A 0.5% fee (50 basis points) is charged on two types of transactions:

Transaction	When	Example
Investor deposits	During the RaisingFunds phase	100,000 USDC deposit → 500 USDC fee → 99,500 USDC credited
Loan repayments	During the Active phase	10,000 USDC payment → 50 USDC fee → 9,950 USDC split to pools

The protocol fee is deducted automatically and transferred to the protocol treasury address stored in the Globals contract.

Fee Configuration

• The default fee is set to 50_000 in 7-decimal format (0.5%)

• The fee can be updated by the Governor via set_fee(caller, fee) on the Globals contract

• Fee changes go through the Timelock for governance delay

The protocol fee is intentionally low to encourage participation. It covers operational costs and funds protocol development.

Late Fees

When a borrower misses a payment deadline, the Pool Manager can apply a late fee penalty.

• Rate: 18% per annum on the overdue amount

• Applied by: The Pool Manager via apply_late_fee(caller)

• Condition: Can only be applied when now > next_due (payment is overdue)

• Effect: Increments the missed payments counter and advances the next due date (prevents double-charging)

Late fees are calculated as:

$$\text{late\_fee} = \text{overdue\_amount} \times \frac{18\%}{12}$$

Late fees accumulate in the vault's late_fees balance and serve as a signal of vault health. They are tracked on-chain via the LateFeeApplied event.
