# Farms

Jewel Scallop Yield Farm runs a fixed set of curated farm pairs. Each pair is a **deposit leg** (your collateral) and a **debt leg** (what the protocol borrows against it and supplies back into Scallop's lending market).

Both pairs currently run at a **65% collateral weight**, giving an effective leverage of **2.86×** and a 35% buffer before the liquidation threshold.

### suiUSDT–USDC

<table><thead><tr><th width="220">Property</th><th>Value</th></tr></thead><tbody><tr><td>Deposit (collateral)</td><td>suiUSDT</td></tr><tr><td>Debt (borrowed)</td><td>USDC (native)</td></tr><tr><td>Collateral weight</td><td>65%</td></tr><tr><td>Effective leverage</td><td>2.86×</td></tr><tr><td>Reward tokens</td><td>sSUI, sSCA</td></tr></tbody></table>

A stablecoin-to-stablecoin pair. Both legs target one US dollar, so the position carries no meaningful directional exposure — the return comes from the lending spread and from Scallop's borrow incentives rather than from price movement.

Because both legs are dollar-denominated, the main things that move this position are the borrow rate and the size of the incentive programme, not the market.

### sbwBTC–zwBTC

<table><thead><tr><th width="220">Property</th><th>Value</th></tr></thead><tbody><tr><td>Deposit (collateral)</td><td>sbwBTC</td></tr><tr><td>Debt (borrowed)</td><td>zwBTC</td></tr><tr><td>Collateral weight</td><td>65%</td></tr><tr><td>Effective leverage</td><td>2.86×</td></tr><tr><td>Reward tokens</td><td>sSUI, sSCA</td></tr></tbody></table>

**Both legs of this farm are Bitcoin.** sbwBTC is the collateral and zwBTC is the borrowed asset, and both price off the same underlying BTC feed. A move in the Bitcoin price therefore moves your collateral and your debt together, and the position's net exposure to BTC stays close to zero.

zwBTC is the debt leg because it is the only BTC market on Scallop that carries borrow incentives — which is where the yield on this pair comes from.

#### What this pair is and is not neutral to

Being BTC-against-BTC removes price direction from the position. It does **not** remove:

* **Borrow-rate risk.** If Scallop's zwBTC borrow rate rises above the incentive rate, the carry turns negative.
* **Incentive risk.** Borrow incentives are a programme, not a guarantee. They can be reduced or ended.
* **Peg risk between the two wrappers.** sbwBTC and zwBTC are different representations of Bitcoin from different issuers. The neutrality of this pair depends on both continuing to track BTC. If one diverges from the other, a position built to have no direction becomes exposed to that spread.
* **Liquidation.** Borrow interest accrues continuously while collateral does not automatically grow to match, so the collateral ratio drifts toward the threshold over time even with the BTC price completely flat.

### Rewards and compounding

Both farms earn **sSUI** and **sSCA** from Scallop's borrow incentive programme. Rewards are harvested and compounded automatically by the protocol on a **four-hourly** cycle — you do not need to claim or reinvest anything manually.

veSCA boosting applies to both pairs, up to a 4× multiplier on incentive rewards. See [Scallop Yield Farming](/sui/scallop-yield-farming.md) for how the boost is calculated.

### Exiting a position

Positions are unwound by repaying the debt and withdrawing the collateral. The protocol supports a **direct repay** path that settles the shortfall from your own debt-coin balance rather than routing through a DEX swap.

This matters for the BTC pair in particular: the on-chain sbwBTC/zwBTC market is thin, so an exit that depended on swapping through it would be exposed to slippage. The direct path avoids that dependency entirely.

The amount required to close is much smaller than the position itself — redeeming the lend leg covers nearly all of the debt, and the gap is only the accrued borrow fee.

See [Position Management](/sui/scallop-yield-farming/position-management.md) for the full lifecycle.
