What is Bucket Protocol？
Bucket is a CDP-based stablecoin protocol on Sui, purpose-built for capital efficiency.
Users deposit supported on-chain assets as collateral to borrow USDB (a USD-pegged stablecoin issued by Bucket). With USDB, they can either loop exposure into a long-term leverage position or unlock liquidity without selling the core asset.
Stablecoin holders can swap their stablecoins (e.g., USDC, USDT) to USDB, then deposit into the sUSDB Savings Pool for competitive, flexible yield.
The problem we solves
Low capital efficiency Many borrowing models keep LTVs low because safety margins and liquidation logic are complex, leaving usable capital under-deployed.
Unpredictable funding costs Variable, supply–demand driven rates swing widely, making long-horizon planning and buffers hard to manage.
Opaque risk boundaries When multiple asset risks are blended within a position and funding rates are volatile, the effective liquidation line becomes hard to track, raising forced-exit risk.
Derivatives capital trapped Productive collateral in derivative forms often cannot be financed efficiently, limiting leverage construction or liquidity access.
Bucket’s solution
High LTV(Loan to Value) Enabled by per-asset isolation and efficient, protocol-run liquidations, so more collateral value can be financed while keeping rules explicit.
Fixed interest rates Funding costs are known upfront and remain predictable, so you can clearly grasp long-term cost and plan buffers and drawdown room deliberately—not reactively.
Predictable risk line A simple, transparent liquidation rule and a live liquidation price surface a clear boundary for management cadence.
Unlock derivatives collateral productivity By supporting select derivative-type collateral, users can build disciplined leverage or free working liquidity against positions that were previously hard to finance.
