# Farms

Farms pay **BSCT** emissions on top of the trading fees you already earn as a
liquidity provider. Biscotti runs two MasterChef contracts — one per AMM — plus
factory-made single-token pools.

## The three farm types

| | Stake | Contract | Emission model |
| --- | --- | --- | --- |
| [V3 Farms](/farms/v3-farms) | Concentrated-liquidity **NFT positions** | `MasterChefV3` | Fixed-duration reward periods (`upkeep`) |
| [Classic Farms](/farms/classic-farms) | **ERC-20 LP tokens** (stable LP) | `MasterChefERC20` | Per-block emissions |
| [SmartChef Pools](/farms/smartchef) | A single token | `SmartChefInitializable` clones | Per-block, pre-funded |

Related: [Coffee Pools](/coffee-pools) are Biscotti's flagship single-token
staking product — stake one token, earn another.

## How emissions work

Both MasterChefs hold `MINTER_ROLE` on the [BSCT token](/token) and mint
emissions directly — no pre-funded budget:

* **Classic farms** mint `bscttPerBlock` every block, split across pools by
  **allocation points** (`allocPoint / totalAllocPoint`).
* **V3 farms** mint in bulk when the operator calls `upkeep(amount, duration)`,
  then stream `rewardPerSecond` to pools by allocation points, and within each
  pool to positions by their share of deposited liquidity.

The BSCT hard cap (1B) bounds all emissions at the token level.

## Harvesting

* Rewards accrue continuously and are claimed with `harvest`/`deposit(pid, 0)`
  (see each farm's page).
* Harvesting never touches your principal — LP tokens and NFTs stay staked.
* `emergencyWithdraw` exits instantly but **forfeits pending rewards** — it
  exists purely as an escape hatch.

:::warning[Emergency withdrawal forfeits rewards]
`emergencyWithdraw` skips reward accounting entirely by design. Use the
normal `withdraw` unless the normal path is unusable.

## APR composition

Farm APR shown in the app has two components:

```
Total APR = Fee APR (from swaps, paid by the pool)
          + Farm APR (BSCT emissions, paid by the MasterChef)
```

Fee APR comes from [Analytics](/analytics) subgraph data; Farm APR is computed
from on-chain emission rates, allocation points and staked liquidity — the
exact formulas are on each farm page.
