# Contract Parameters

| Parameter                 | Value                            | Notes                                                                                                                         |
| ------------------------- | -------------------------------- | ----------------------------------------------------------------------------------------------------------------------------- |
| bfUSD decimals            | 6                                | Matches USDT/USDC standard precision                                                                                          |
| hbfUSD supply cap         | 100,000,000 shares               | Controls risk for the low-risk pool                                                                                           |
| pbfUSD supply cap         | 2,000,000 shares                 | Controls risk for the high-yield pool                                                                                         |
| Ratio precision           | 1e8                              | `currentRatio()` and `epochRatios()` use this scaling to convert between bfUSD and shares                                     |
| Standard redemption delay | 3 epochs + manual claim          | Users must wait for `settlementDelay` epochs before calling `claimWithdrawals`                                                |
| Instant redemption fee    | 0.5%                             | Charges the fee in bfUSD and enforces a quota on the redeemer contract                                                        |
| Staking/unstaking fees    | 0                                | Minting, depositing, withdrawing, and unstaking are free; only instant redemption and cross-chain transfers charge small fees |
| Cross-chain fee           | Variable (per `crossChainFee()`) | Charged when sending shares via LayerZero; uses `FeeLibrary.Fees` structure                                                   |
| Oracle                    | Chainlink                        | Stablecoins prices are sourced from Chainlink oracles                                                                         |
| Epoch tracking            | `epochRatios(uint256 epoch)`     | Each epoch stores `(startRatio, endRatio, startTime, endTime)` to rebuild historical share values                             |

Additional notes:

* `StakedBitFiStablecoin` exposes `maxDeposit`, `maxMint`, `maxWithdraw`, and `maxRedeem` to enforce the supply caps and ensure `supplyCap` is never exceeded.
* `previewDeposit`, `previewMint`, `previewWithdraw`, and `previewRedeem` reuse the vault ratio logic, making the user experience more predictable and user-friendly.
* `pendingWithdrawal` data (requested epochs, claimable epochs, fees) can be read through the `withdrawals(uint256 id)` view and should be shown in any UI that lists queued redemptions.
