System Overview

What are the primary use cases of Bucket Protocol?

1. Borrow

Deposit your $SUI or other collateral to open a position and receive a $BUCK stablecoin loan. Keep your collateral ratio above the Minimum Collateral Ratio (MCR) — ideally over 150%. A one-time borrow fee of 0.5% to 5% applies, along with fixed interest based on loan demand.

2 . PSM

Swap $USDT or $USDC to $BUCK at a 1:1 ratio with zero fees using PSM In via Bucket Swap.

For PSM Out, swap $BUCK back to $USDC at a 1:1 ratio, with an additional 0.5% switch-out fee.

3 . Stake $BUCK

Stake your $BUCK to receive $sBUCK and earn the BSR (BUCK Saving Rate).

4 . sBUCK Saving Pool

Deposit $sBUCK into Bucket Saving Pool to earn extra $SUI reward.

5. Redeem

Exchange your $BUCK for an equivalent value in collateral. This functionality benefits collateral holders by providing an opportunity to extract value and also aids in maintaining $BUCK's pegged value. The rationale behind this will be explained in a later chapter.

6 . Tank Pool

Deposit $BUCK into the Tank Pool to participate in liquidations, acquiring collateral at advantageous rates.
