# 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 1. **Low capital efficiency**\ Many borrowing models keep LTVs low because safety margins and liquidation logic are complex, leaving usable capital under-deployed. 2. **Unpredictable funding costs**\ Variable, supply–demand driven rates swing widely, making long-horizon planning and buffers hard to manage. 3. **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. 4. **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. # Key Advantages Bucket is built for **capital efficiency**. Its design choices translate into clear, durable advantages for leverage users, liquidity seekers, and stablecoin allocators. ### Fixed per-asset interest rates * Rates are **fixed by collateral type**. * Funding costs are **known upfront and remain predictable**, so you can **clearly grasp long-term cost** and plan buffers/drawdowns deliberately—not reactively. * **Result:** long-horizon strategies run on discipline instead of rate anxiety. ### Explicit, predictable risk boundaries * A simple **CR(Collateral Ratio) / MCR(Minimum Collateral Ratio)** rule defines the boundary; the app surfaces a **live liquidation price** for every position. * **Per-asset isolation** avoids the confusion of **blended multi-asset risk** paired with volatile rates. * **Result:** fewer forced exits from opaque mechanics; management centers on cadence and buffer. ### High LTV (Loan to Value) * **Per-asset CDPs** isolate risk instead of blending multiple assets in one pot. * **Protocol-run liquidations** execute consistently whenever **CR < MCR**, making enforcement predictable. * **Result:** more usable capital from the same collateral, without adding ambiguity to risk. ### Turning derivatives collateral into productive capital * Support for **select derivative-type collateral** (see *Markets*) unlocks financing for positions that were hard to deploy. * Users can **build leverage** or **free liquidity** against LSTs / sCoins / similar collateral while keeping core exposure. * **Result:** derivative exposure becomes active capital, not idle constraint. *** ### What this enables in practice * **Disciplined, long-term leverage** with a stable cost curve and a clear risk line. * **Liquidity without selling** the core position—borrow USDB against collateral and manage CR with precision. * **A clean savings rail** for stablecoin capital via **sUSDB** and the **sUSDB Savings Pool**. # What is USDB？ **USDB** is a decentralized, **over-collateralized** stablecoin issued by Bucket on **Sui**, designed to track **$1** USD and power capital-efficient leverage and liquidity across the ecosystem. USDB serves two distinct user needs: * **Volatile-asset holders** borrow USDB against collateral to loop exposure (long-term leverage) or access liquidity without selling core positions. * **Stablecoin allocators** avoid asset volatility while earning yield by holding USDB and depositing into the **sUSDB Savings Pool**. *** ### How to get USDB #### Via CDPs (borrow) Open a single-asset CDP, post supported collateral, and **borrow USDB**—typically for leverage or liquidity without selling the core asset.\ *Details: see **“How CDPs Work”*** #### Via the PSM ( Stablecoins → 1:1 mint USDB) Swap supported stablecoins to **USDB** through the **Peg Stability Module (PSM)** at 1:1 (not included fees). Ideal for stablecoin allocators who want USDB without touching volatile assets. **Supported assets & fees** | Direction | Asset | Fee | | ------------------- | ------------- | --------- | | PSM IN (Mint USDB) | USDC | **0%** | | PSM IN (Mint USDB) | USDT | **0.05%** | | PSM OUT (Burn USDB) | All supported | **0.30%** | *Peg behavior, routing, and scenarios: see **“USDB Peg”*** *** ### Where to earn on USDB Deposit USDB into the **sUSDB Savings Pool** for **competitive, flexible yield** with **real-time accrual** and **flexible redemption**.\ *Details: see **“sUSDB and Yield.”*** # How CDP Work This page explains how Bucket’s collateralized debt position (CDP) operate: the actions you can take, how costs accrue, the core risk metrics (CR/MCR), and how liquidation thresholds are determined.
Core actions * **Open position** - Create a CDP by depositing supported collateral then borrow USDB. * **Deposit more collateral** to existing position - Increase CR(Collateral Ratio) by increase collateral value. * **Withdraw collateral from** existing position - Take partial collateral out, only if your position remains healthy(CR>MCR) after the change. * **Borrow more USDB** - Draw more USDB liquidity against your collateral. * **Repay** - Two ways * **Repay with USDB** - Use USDB you hold to repay debt. * **Repay with collateral** - Sell a portion of collateral into USDB to repay debt (available only for certain assets with sufficient DEX liquidity). * **Close position** - Fully repay outstanding debt; withdraw remaining collateral. > Rule of thumb: After every action, your position must satisfy **CR >= MCR** for that collateral type. *** ### Fees * **No one-time borrow fee.** * **Fixed borrow interest rate.** Interest Rates for different collateral type are listed on [**Markets**](https://www.bucketprotocol.io/market).(Interest accrues in **real time)** *** ### Risk metrics * **Collateral Ratio (CR)**\ CR = Collateral Value / Debt value \= (Collateral Price \* Collateral Amount) / (initial Borrow Amount + Accrued Interest Fee) * **Minimum Collateral Ratio (MCR)** \ Each collateral has a fixed MCR requirement. If your **CR < MCR**, the position becomes eligible for liquidation. * **Liquidation price** For a given debt and collateral value\ Liquidation Price = (MCR \* Debt) / Collateral Amount ### Mint caps * **Mint caps** exist per collateral to help manage market depth during liquidations and reduce slippage risk in extreme conditions. ### Example **Assumptions:** * SUI price: $5.00 per SUI * Collateral: 1,000 SUI ($5000) * SUI MCR Requirement = 110% **Max borrow at open :**\ Debt\_max = Collateral Value / MCR = 5,000 / 110% \~= 4,545.45 USDB **If you borrow 4,000 USDB:** * Entry CR = 5,000 / 4,000 \* 100%= 125% * Liquidation price: \= (MCR \* Debt) / Collateral Amount \= (110% \* 4,000) / 1,000 \= $4.40 per SUI * If SUI falls near $4.40, your CR would approach 110% and the position could be liquidated. # Liquidation This page explains when a position can be liquidated, how protocol-run liquidation is executed, and what the economic outcome looks like for the user. ### When liquidation can happen * **Trigger:** A position becomes liquidatable **as soon as Collateral Ratio(CR) < Minimum Collateral Ratio(MCR).** * **Scope:** Liquidation is **full seizure**. When a position is liquidated, **all collateral** in that CDP is taken to cover the debt. * **Executor:** Liquidations are **handled by the protocol**. > Minimum Collateral Ratio(MCR) requirements are different for each collateral assets, please check [Market Page](https://www.bucketprotocol.io/market) for the info. *** ### Liquidation price For a given **Debt** and **Collateral Amount**, using **MCR** as a ratio (e.g., 110%): Liquidation Price = (MCR \* Debt) / Collateral Amount This is an approximate trigger price for the collateral. The app also displays your **live liquidation price**. *** ### How liquidation is executed To maximize reliability and settlement efficiency, the protocol uses the following on-chain flow: 1. **Flash-mint USDB** to immediately repay the CDP’s outstanding debt on-chain. 2. **Seize all collateral** from the liquidated CDP. 3. **Sell the seized collateral for USDB** using on-chain venues. 4. **Repay the flash-minted USDB** from step 1.
*** ### Loss and user outcome * **User loss intuition:** at the liquidation threshold (CR = MCR), the collateral value equals `MCR * Debt`. Because debt must be repaid first and all collateral is seized, the user’s economic loss around the threshold is approximately: \ User loss ≈ CollateralValue - Debt = (MCR - 100%) \* Debt **Concrete illustration** * Suppose a user has collateral valued at **$150** and borrowed **100 USDB**, with **MCR = 110%** . * If price declines so that collateral value falls to **$109.99** (i.e., CR drops below MCR), the position becomes liquidatable. * Upon liquidation, **all $109.99** worth of collateral is taken to cover the **$100** debt. The user keeps the 100 USDB previously borrowed. * **Approximate loss:** `$109.9 - $100 = $9.99`, which matches the formula ≈`(MCR - 1) * Debt = 0.10 * 100 = $10`. *** ### Bad-debt backstop If an extreme market move causes collateral proceeds to be **less than the debt**, the protocol relies on an **Insurance Fund** as a backstop. * **Funding source:** a portion of protocol revenue. * **Purpose:** help ensure the system can continue operating through extreme scenarios. *** ### Avoiding liquidation If your position approaches the liquidation price, you can reduce risk by either: * **Depositing more collateral to increase position's CR.** * **Repaying part of the debt** (repay with USDB, or repay with collateral where available) to **increase position's CR.** *** ### Roadmap An **improved liquidation mechanism**—aimed at **further reducing user liquidation risk and potential loss**—is in progress and will be documented upon release. # USDB Peg **USDB** is a USD-pegged stablecoin issued by **Bucket**.\ The peg targets **$1** and is supported on-chain by two components that work with open markets: * **Peg Stability Module (PSM)** — a trustless 1:1 conversion rail between USDB and supported stablecoins, subject to a PSM fee. * **Market arbitrage** — traders buy/sell across venues to close any price gap around $1. *** ### Peg Stability Module (PSM) **What it does** * Enables **1:1 conversions** between USDB and supported stablecoins. * A **PSM fee** applies. **Supported assets and fees**

PSM IN (stablecoin -> USDB)USDC0%
PSM IN (stablecoin -> USDB)suiUSDT0.05%
PSM OUT (USDB -> stablecoin)USDC, suiUSDT0.30%
*** ### Price Stability & Arbitrage Let: * `price_usdb` = USDB market price (USD) on DEX * `fee_in` = PSM IN fee * `fee_out` = PSM OUT fee #### Scenario A — Upward depeg (USDB > $1) 1. Acquire USDB near $1 via **PSM IN** using a supported stablecoin. 2. Sell USDB on the market at `price_usdb > 1`. 3. **Gross spread per USDB**\ Spread\_up ≈ `price_usdb` - (1 + `fee_in`) 4. **Break-even check**\ `price_usdb` > 1 + `fee_in` + (gas + slippage) 5. As selling pressure increases, `price_usdb` converges toward $1. #### Scenario B — Downward depeg (USDB < $1) 1. Buy USDB on the market at `price_usdb < 1`. 2. Exit via **PSM OUT** to a supported stablecoin at \~$1 minus `fee_out`. 3. **Gross spread per USDB**\ Spread\_down ≈ (1 - `fee_out`) - `price_usdb` 4. **Break-even check**\ `price_usdb` < 1 - `fee_out` - (gas + slippage) 5. As buying pressure increases, `price_usdb` converges toward $1. ### Flash-mint assisted arbitrage For capital efficiency, advanced users can use **Flash Mint** to source and retire USDB within one transaction, pairing the opposite leg through PSM or market liquidity to capture `Spread_up` or `Spread_down` as above. # sUSDB and Yield This page covers two layers of yield for USDB stablecoin holders: * **sUSDB and BSR**: stake USDB to get sUSDB; value appreciates via an increasing exchange rate driven by the Base Savings Rate (BSR). * **sUSDB Savings Pool**: deposit sUSDB to sUSDB Savings Pool to earn additional Sui rewards on top of BSR. *** ### sUSDB and BSR #### What is BSR The Base Savings Rate (BSR) is Bucket’s fixed savings rate for USDB. It does not apply to idle USDB by default. When activated, BSR accrues in real time by increasing the exchange rate between sUSDB and USDB. The app shows your fixed APR for BSR and the current exchange rate. #### What is sUSDB sUSDB is the yield-bearing stablecoin you receive when you stake USDB into the staking pool to activate BSR. Yield does not change your sUSDB balance; instead, each unit of sUSDB represents more USDB over time as the exchange rate rises. #### Mechanics * Stake USDB -> mint sUSDB at the current exchange rate. * Unstake sUSDB -> receive USDB at the live exchange rate. * Balances and the exchange rate update in real time. * No stake or unstake fee. No lockup. **Formulas** minted\_sUSDB = staked\_USDB / exchange\_rate unstaked\_USDB = sUSDB\_balance \* exchange\_rate *** ### sUSDB Savings Pool **What it is** * A savings pool for sUSDB that pays **additional Sui rewards** (Savings Yield) on top of BSR. **What you earn** * Savings rewards accrue continuously and are claimable at any time. * Your app-level **Estimated APR** shows the combined rate: **BSR + SUI rewards APR**. **Deposit and withdraw** * Deposit sUSDB into the **sUSDB Savings Pool** to start earning Sui rewards. * Withdraw whenever you want with no fees. # Bucket Upgrade and Migration This page explains the **major Bucket upgrade** and how to **migrate** from the legacy system. It is intended for: * **Legacy CDP users** * **BUCK holders** (including BUCK Savings positions) *** ### What changed — background & purpose The upgrade focuses on **cost efficiency, clarity, and safety**: * **One-time borrow fee (0.3%) removed**\ With Recovery Mode gone, a borrow fee is no longer necessary. This aligns with market practice and makes borrowing **more cost-efficient (Interest fee only)**. * **Recovery Mode removed**\ Reduces user learning cost and eliminates unpredictable, system-level risk interactions — you only monitor **your own CR(Collateral Ratio) / liquidation price**. * **Tank removed (protocol-run liquidations)**\ Liquidations are fully handled by the **protocol**. An **improved liquidation mechanism** (to further reduce user liquidation risk and potential loss) is **on the way.** * **Position ordering removed**\ The system no longer requires CDP ordering. This **improves scalability** and removes the **minimum debt** constraint. Result: a simpler, safer, more cost-efficient, and more flexible CDP system. *** ### Migration phases Bucket runs migration in **phases** (progression depends on migration uptake). * **Phase 1 — Legacy usable, migration encouraged** * **CDP:** Legacy positions remain fully functional. New CDPs offer **no borrow fee** and higher **Borrow Rewards**. * **Stablecoin Savings:** Higher **APR** on the USDB Savings Pool to encourage migration. * **Phase 2 — Legacy exit-only** * **CDP:** Legacy position becomes **exit-only** (no new **Borrow**, no new positions), **BUCK minting disabled**. * **BUCK Savings Pool:** **Withdraw/Migrate only**. * **Phase 3 — Legacy hidden** * The app UI **no longer shows** legacy CDPs / BUCK Savings positions. *** ### Old positions → New positions | Legacy | New | Conversion | Fee | | -------------------------------------- | ----------------------------------- | -------------------------------------- | --------------------- | | **BUCK** | **USDB** | **1:1 via Migrate** | **No fee** (gas only) | | **Legacy CDP (BUCK-denominated debt)** | **New CDP (USDB-denominated debt)** | One-click **Migrate CDP** | **No fee** (gas only) | | **BUCK Savings Pool** | USDB **Savings Pool** | One-click **Migrate Savings position** | **No fee** (gas only) | *** ### Migrate CDP (legacy → new) **What happens** * Your **debt unit** changes from **BUCK** to **USDB**. * The position moves to the **new CDP mechanism** (no borrow fee; fixed per-asset rate; protocol-run liquidation). * **Collateral, notional debt, CR, and liquidation price** remain the same. **Step-by-step** 1. Open **Dashboard** → find the **legacy position** → click **Migrate (Only for collateral that supported by New Market)**.
2. Review the preview.
3. Confirm to execute (Migrate). 4. The position reappears as a **USDB-denominated CDP** under the new CDP model (New position). **Notes** * You **do not** need to close and reopen the vault. * **Borrow fee = 0** on the new CDP model. *** ### Migrate Stablecoin Savings **What happens** 1. **Withdraw BUCK from BUCK Savings Pool.** 2. **Migrate BUCK → USDB (1:1)**. 3. **Deposit USDB into USDB Savings Pool.** **Step-by-step** 1. Open **Dashboard** → find your **BUCK Savings** position → click **Migrate**. 2. Review the preview. 3. Confirm (Migrate). 4. Your new Savings position appears on New position page (USDB Savings). *** ### Costs & requirements * **Protocol migration fee:** **None** (all flows above are fee-free from the protocol). * **Network fee:** You need some $**SUI** for gas. *** ### After migration — what to expect * **CDP:** Shown as a **New position** on your **Dashboard**, with **fixed interest rate** and **no one-time borrow fee**. * **Stablecoin Savings:** Shown under **Stablecoin Savings** as **USDB**. Rewards are **claimable anytime** (Higher APR). # Borrowing This guide shows how to open a CDP, deposit collateral, and borrow USDB. ## Step-by-step 1. **Select asset and open the Borrow panel**\ Choose the collateral asset on [**Market page**](https://www.bucketprotocol.io/market) or go to the [**Borrow page**](https://www.bucketprotocol.io/borrow?token=SUI) and pick an asset.
2. **Enter amounts** * Input **Collateral to deposit**. * Input **USDB to borrow**.\ The panel previews **CR**, **MCR**, **Liquidation/Market Price**, and the **Fixed Interest Rate**.
3. **Review health**\ Confirm the **CR bar** is in a healthy zone and the **CR >= MCR(Liquidation)**.
4. **Submit**\ Confirm the single transaction that both **deposits collateral** and **borrows USDB**.
5. View your position on [Dashboard](https://www.bucketprotocol.io/dashboard)
*** ### Costs and interest * **No one-time borrow fee.** * **Fixed borrow rate per asset.** See **Markets** for current rates. * Interest accrues **in real time** and is added to your debt continuously. *** ### Risk and health checks * **Collateral Ratio (CR)**\ CR = Collateral Value / Debt \= (Oracle Price \* Collateral Amount) / (Principal + Accrued Interest) * **Minimum Collateral Ratio (MCR)**\ Each asset has a fixed MCR. Your position must keep **CR >= MCR**. * **Liquidation price**\ For given Debt and Collateral Amount:\ Liquidation Price = (MCR \* Debt) / Collateral Amount > Neutral reminder: Always watch your **CR** and **Liquidation Price**. If CR falls below MCR (CR < MCR), the position becomes liquidatable. *** ### Example (SUI) **Assumptions:** * Collateral: **1,000 SUI** * Oracle price: **$5.00 per SUI** -> Collateral Value = **$5,000** * **MCR (SUI) = 110% (1.10)** **Borrow 3,000 USDB** * Entry CR = $5,000 / $3,000 = **1.6667 (166.67%)** * Liquidation Price = (1.10 \* 3,000) / 1,000(SUI) = $3.30 per SUI **Borrow 4,000 USDB** * Entry CR = 5,000 / 4,000 = **1.25 (125%)** * Liquidation Price = (1.10 \* 4,000) / 1,000 = $4.40 per SUI > Numbers are illustrative. Real-time accrual will slowly increase debt after opening. # Position Management Manage an open CDP from your Dashboard. Every action shows an after-action simulation (CR and Liquidation Price). Submissions require CR ≥ MCR(liquida. ## Where to manage * Open **Dashboard page** and locate your position card.
* Click **Manage** on the position card.
* In the Manage panel, use the tabs: * **Deposit** * **Withdraw** * **Borrow** * **Repay** * **Repay with USDB** * **Repay with collateral**
*** ## What the position card shows * **Collateral amount & value**, **Debt**, and fixed **interest rate.** * **CR (Collateral Ratio)** with a **health bar** * **Market Price** and **Liquidation Price**
**Health bar colors:** * **Green** = conservative * **White** = normal * **Yellow** = aggressive * **Red** = very risky * Liquidation label = Minimal Collateral Ratio of the Collateral type
*** ## Actions > The after-action simulation appears on every tab to preview CR and Liquidation Price before you confirm. ### Deposit(add collateral) 1. Go to **Deposit** and enter the amount to add. 2. Review the after-action **CR** and **Liquidation Price**. 3. Confirm(Deposit). **Effect:** CR increases; Liquidation Price moves lower (safer).
*** ### Borrow more USDB 1. Go to **Borrow** and enter the amount of **USDB** you want to borrow. 2. Review the after-action **CR** and **Liquidation Price (CR must remain ≥ MCR(Liquidation)**. 3. Confirm(Borrow). **Effect:** Debt increases; CR decreases; Liquidation Price moves higher (riskier). *Fixed interest rate is based on debt amount*
*** ### Withdraw collateral(partially) 1. Go to **Withdraw** and enter the amount to take out. 2. Review the after-action **CR** and **Liquidation Price (CR must remain ≥ MCR(Liquidation)**. 3. Confirm(Withdraw). **Max withdraw note:** the UI shows a **max-withdraw estimate** that trends your CR close to the MCR line. **Effect:** CR decreases; Liquidation Price moves higher (riskier).
*** ### Repay debts #### ***Repay with USDB*** * Enter the amount of **USDB** to repay and confirm. * **Max repay** behavior: * If wallet USDB balance ≥ total debt, Max fills the **entire outstanding debt** (including real-time interest). * Otherwise, Max uses your **full wallet balance**. * **Partial repay** is supported. **Effect:** Debt decreases; collateral remain the same. CR increase(Safer).
***Repay with collateral*** * For supported assets, sell a portion of collateral into **USDB** and repay in one flow. * The modal previews: **collateral to sell → USDB repaid → new CR**. * Under the hood, the protocol routes the steps atomically; availability depends on on-chain DEX liquidity. **Effect:** Debt decreases; collateral also decreases. CR typically **improves** if the debt reduction is proportionally larger than collateral sold.
*** ### Close position **Close** fully repays the position and returns all remaining collateral to your wallet in a single transaction. Choose one of the two paths: * **Close — Repay with USDB** * **Requirement:** your wallet’s USDB balance must be **≥ total debt**. * **What happens:** repays the **entire** debt using your USDB and withdraws **100% of the collateral** back to your wallet.
* **Close — Repay with collateral** * **Availability:** always available(Slippage < your setting). * **What happens:** sells a **portion of collateral** into USDB, repays **all** debt, then withdraws the **remaining collateral** to your wallet. * The modal shows a preview: **collateral used(to sell) → USDB repaid → collateral left**.
*** ### Examples **Shared assumptions** * Collateral: **1,000 SUI** * Market price: **$5.00** per SUI → Collateral Value **$5,000** * Debt: **4,000 USDB** * **MCR (Liquidation) = 110% (1.10)** * Baseline: **CR = 5,000 / 4,000 = 1.25 (125%)** * Liquidation Price = (1.10 × 4,000) / 1,000(SUI) = $4.40 per SUI **A) Deposit 200 SUI** * New collateral = **1,200 SUI** (value **$6,000**) * New **CR = 6,000 / 4,000 = 1.50 (150%)** * New Liquidation Price = (1.10 × 4,000) / 1,200(SUI) ≈ $3.67 per SUI **B) Repay with collateral 500 USDB** * At $5.00/SUI (ignoring routing fees), sell **\~100 SUI** → **\~500 USDB** to repay. * New collateral = **900 SUI** (value **$4,500**); New Debt = **3,500 USDB** * New **CR = 4,500 / 3,500 ≈ 1.286 (128.6%)** * New Liquidation Price = (1.10 × 3,500) / 900 ≈ $4.28 per SUI # Leverage in Bucket Bucket supports two ways to build a leveraged long on supported assets: * **One-click Leverage** (currently for **SUI/LST** and Wrapped **BTC**) * **Manual looping** (all other supported collaterals) Both paths keep you inside a single CDP with fixed-rate borrowing. Every action shows an **after-action simulation**. *** ### One-click Leverage ### Step-by-step 1. Select your **deposit asset**. 2. Select the **target asset**. 3. **Enter** the deposit amount. 4. **Set** your target leverage (> 1.1×). 5. **Review** the preview and costs, then **Confirm** to execute (one transaction).
### Preview & safety * Before confirming, you’ll see a simulation of the position at **Detail.** * A simple **target-leverage health bar** helps you gauge risk.
**Routing & slippage** * Swaps are routed via the **Cetus aggregator**. * You can set **slippage tolerance** (default **0.5%**).
**Costs shown in the panel** * **Flash-loan fee** * **Price impact** (swap-side estimate)
### How it works The Leverage feature allows users to amplify their exposure to supported assets by using USDB flash minting to automatically create a leveraged position in one click.Leverage Process (Example with SUI):A user starts with 100 USDC and targets approximately 3x SUI exposure. 1. User deposits 100 USDC 2. Flash-mints USDB worth 200 USDC 3. Swaps the user’s 100 USDC + flash-minted USDB for 300 USDC worth of SUI 4. Uses 300 USDC worth of SUI as collateral → borrows USDB worth 200 USDC 5. Uses the borrowed USDB to repay the flash-mint 6. Leveraged position is established Final Position: * Collateral: 300 USDC worth of SUI * Debt: USDB worth 200 USDC + borrow fee * Net SUI Exposure: \~3x the initial deposit The same process works for other supported assets (e.g., BTC or SUI LST), with adjustments based on the asset type. *** ### Manual looping (all supported collaterals) Use manual steps when one-click isn’t available: 1. **Deposit collateral** 2. **Borrow USDB** 3. **Swap USDB → more collateral** 4. **Deposit** the new collateral 5. **Repeat** until you reach your desired risk level *** ### De-leverage & raising CR To reduce leverage or raise your CR: * **Repay with collateral:** use the slider to choose how much collateral to sell for USDB, preview the **USDB repaid** and **new CR**, then confirm. * **Repay with USDB:** repay from USDB in your wallet (you can swap into USDB first). * After repayment, **CR rises** and your liquidation price **moves lower** (safer). # Earning with USDB This guide covers **USDB Stablecoin Savings**—a two-layer flow for stablecoin holders: * **Layer 1 — sUSDB (BSR):** stake USDB to receive **sUSDB** and earn via the Base Savings Rate (BSR). * **Layer 2 — sUSDB Savings Pool:** depoist sUSDB to earn **additional Sui rewards**. * Total APR = BSR + Sui rewards APR **Entry point:** go to **Earn → Stablecoin Savings** to start. *** ### Deposit 1. **Choose deposit asset & amount** * Select **USDB** to deposit directly, or pick a supported stablecoin. * If non-USDB, the app will **swap to USDB** first (Route and **swap rate** shown). 2. **Review the preview(Route)** * See swap simulation, **minted sUSDB** (from USDB) and the **Savings APR** you’ll earn after depositing into the Savings Pool. 3. **Confirm(Deposit)** * Atomically performs:\ Swap for **USDB → stake USDB for sUSDB → deposit sUSDB into the sUSDB Savings Pool**. 4. **Track** * Your Savings position and **claimable Sui rewards** appear on the page and on the **Dashboard**. > Notes: **No deposit/withdraw fee. No lockup.**\ > Claims are available from both **Stablecoin Savings** and **Dashboard** when you have a Savings position.
*** ### Claim Sui rewards * When you have a USDB Savings position, your **claimable Sui rewards** update in real time. * Click **Claim** anytime on [**Stablecoin Savings**](https://www.bucketprotocol.io/earn/stable?action=deposit\&token=USDC) or from your [**Dashboard**](https://www.bucketprotocol.io/dashboard).
*** ### Withdraw 1. **Choose withdraw asset & amount** * Select **USDB** to withdraw directly, or pick a supported stablecoin. * If non-USDB, the app will **swap USDB to the stablecoin you want to withdraw**. 2. **Review the preview(Route)** 3. **Confirm(Withdraw)** * Atomically performs:\ **withdraw sUSDB from the Savings Pool → unstake sUSDB to receive USDB**.
# What is $BUT and deBUT This page explains what BUT and deBUT are, how the deBUT weighting model works, and how to stake / unstake. ### Overview * **$BUT** — [The native protocol token of Bucket](https://suivision.xyz/coin/0xbc858cb910b9914bee64fff0f9b38855355a040c49155a17b265d9086d256545::but::BUT). * **deBUT** — a **non-transferable weighting** tied to your **staked BUT**. * Think “**staking power**”: **deBUT weighting determines the strength of your future utilities and rewards.** * **Fully staked:** `1 BUT → 1 deBUT` (weight **1:1**). * Starting an **unstake** introduces a **unstake period** and a **penalty** (details below). *** ### Unstake mechanics When you start **unstaking**, you choose an **unstake period `T`** between **30 and 365 days**. Your **final BUT received** at completion depends on `T`: * At **T = 30 days**, you receive **30%** back (**70% penalty**). * At **T = 365 days**, you receive **100%** back (**0% penalty**). * For unstake period in between, the **penalty decreases linearly** from **70% → 0%**. #### Penalty formula Let `T` be the chosen unstake period in **days** (30 ≤ T ≤ 365). Then \ penalty\_ratio = 0.70 × ( 1 − (T − 30) / 335 ) received\_ratio = 1 − penalty\_ratio * Checks: * `T = 30` → `penalty = 70%`, `received = 30%` * `T = 365` → `penalty = 0%`, `received = 100%`
*** ### deBUT weight during the unstake countdown While an amount `U` of your staked BUT is in the **unstake period**, the **weight of that portion** is counted at **50%** until the countdown completes or is cancelled. * Let `S_total` be your staked BUT before requesting to unstake. * **Effective deBUT weight during the countdown**: deBUT\_weight = (S\_total − U) × 1.0 + U × 0.5 * **Cancel Unstake:** restores **1:1** weight instantly. * At completion, settlement follows the **received/penalty** ratios from the formula above. **Example (all 100 BUT unstaked for 30 days):** * During the 30-day countdown: **deBUT weight = 100 × 0.5 = 50**. * At completion (T = 30): `received_ratio = 0.30` → you **claim 30 BUT**; **70 BUT** goes to the **penalty pool**. * If you **cancel** before completion: stake returns to **100 BUT** and **deBUT weight = 100** (1:1). > **Important:** After the chosen unstake period **completes**, the request **cannot be cancelled**. *** ### Penalty pool & distributions * **Penalty destination:** BUT deducted by penalty accumulates in a **penalty pool**. * **Future distribution:** The pool is intended to be **distributed to deBUT holders**. * Details, cadence, and methodology: **To be announced**. *** ### How to stake BUT (Step-by-step) All actions are available on the [**BUT page**](https://www.bucketprotocol.io/but). 1. Open the **BUT** page → Check **Stake tab**.
2. Enter the **BUT amount** to stake and **check the preview**.
3. **Confirm(Stake)**.
*** ### How to unstake BUT (Step-by-step) 1. On the [**BUT** page](https://www.bucketprotocol.io/but) → Check **Unstake tab.**
2. Input Unstaking amount and choose an **unstake period `T`** between **30–365 days**.
3. The preview shows: * **deBUT weight during countdown** * **penalty\_ratio** (expected penalty)
4. **Confirm** to start the countdown.
*** #### Cancel Unstake 1. Check Unstaking requests on BUT page.
2. While the countdown is active, click **Cancel Unstake**.
3. Your stake returns to **fully staked** and **deBUT = 1:1** immediately.
> **Note:** After the selected period completes, **cancel is unavailable**. *** ### Examples **Example A — 30-day Unstake** * `T = 30` → `received_ratio = 0.30` → you **claim 30%**; **70%** goes to the **penalty pool**. * During the countdown, the unstaking portion counts at **50% deBUT weight**. **Example B — 180-day Unstake** * `T = 180` →\ `penalty_ratio = 0.70 × (1 − (180 − 30)/335) ≈ 0.3955`\ `received_ratio ≈ 0.6045` → claim **\~60.45%** at completion. * During the countdown, that portion’s **deBUT weight = 50%**. **Example C — 365-day Unstake** * `T = 365` → `received_ratio = 1.00` (no penalty). * No penalty; the portion still counts as **50% deBUT weight** **only** if it is in an active countdown (i.e., until completion or cancellation). # Technical Resources This page contains useful resources for developers and users interacting with Bucket. ## Bucket SDK **The Bucket SDK provides tools for developers to easily integrate Bucket Protocol into their dApps and services on Sui — including CDP, PSM, USDB Savings, and advanced flows like Flash Mint and Flash Loan.** * **GitHub:** [Bucket SDK](https://github.com/Bucket-Protocol/bucket-protocol-sdk/tree/v2) * Start with the [**README**](https://github.com/Bucket-Protocol/bucket-protocol-sdk/blob/v2/README.md) for setup, code samples. *** ## Contract Addresses ### [Mainnet Interface](https://github.com/Bucket-Protocol/bucket-protocol-sdk/blob/v2/sdk/src/consts/config.ts)
