# Product Guide ## **Prepare Yourself** To use Solido Cash and mint $CASH, you first need to open a Trove in the Solido UI. In this section, we’ll walk you through the preparation steps. #### **1. Install the StarKey Wallet** [Download](https://chromewebstore.google.com/detail/starkey-wallet-the-offici/hcjhpkgbmechpabifbggldplacolbkoh) and install the StarKey Wallet on your device. This wallet allows you to interact with the Solido Cash application. #### **2. Acquire $SUPRA** You’ll need $SUPRA for two purposes: * To pay transaction fees on the Supra blockchain * To use as collateral to mint $CASH You can acquire $SUPRA through exchanges where it is listed. Check [CoinMarketCap](https://coinmarketcap.com/currencies/supra/#Markets) for the latest information and supported markets. Once purchased, transfer your $SUPRA to your StarKey Wallet. Alternatively, you can buy $SUPRA using [Dexlyn](https://app.dexlyn.com), a decentralized bridge and exchange built on the Supra blockchain. No KYC is required. Here’s how: **Using Dexlyn:** a. Visit the [Dexlyn Bridge](https://app.dexlyn.com/bridge) and connect both your MetaMask and StarKey wallets.\ b. Bridge USDC from Ethereum to Supra. Once complete, you'll receive **dexUSDC** on the Supra network, along with a small amount of $SUPRA to cover gas fees.\ c. Head to the Swap page on Dexlyn and exchange your dexUSDC for $SUPRA. > You’ll need a minimum of **$50 worth of $SUPRA** to open a Trove on Solido Cash. Depositing more will keep your loan-to-value healthy and keep you safe from liquidations. *** ## Solido Flow/ Stake $SUPRA Flow operates through three core actions: * **Stake** SUPRA → Receive stSUPRA * **Unstake** stSUPRA → Start the SUPRA claim process * **Withdraw** SUPRA → Claim tokens after the waiting period *** #### Staking SUPRA * Navigate to the Flow section within the app. * Ensure your wallet is connected and your SUPRA balance is visible. * Enter the amount of SUPRA to stake. * Review the amount of **stSUPRA** you’ll receive. * Click **STAKE** and confirm the transaction in your wallet. * Your updated stSUPRA balance will be reflected in your portfolio at the top of the page. *** #### Unstaking stSUPRA * Switch to the **UNSTAKE** tab. * Enter the amount of **stSUPRA** you wish to convert back to SUPRA. * The equivalent SUPRA amount will be displayed. * Click **UNSTAKE** and approve the wallet transaction. * Your request will enter the **Claim Period.** *** > #### ⏳ Claim Period > > After you initiate an unstake, your SUPRA isn’t available right away. Instead, the protocol places your request into a claim queue, creating a short waiting period while validators finalize the exit. Once this claim period ends, you’ll be able to move forward and withdraw your SUPRA. *** #### Withdrawing SUPRA Once the claim period has ended: * Go to the **WITHDRAW** tab. * Your claimable SUPRA balance will be shown. * Click **WITHDRAW** and confirm the wallet transaction. * The tokens will be transferred to your wallet. > ⚠️ Note: Withdrawals can only be completed once the claim period is over. ## **Solido Cash / Borrow $CASH by opening a Trove** Once you have collateral in your StarKey Wallet, connect your wallet to [Solido Cash](http://app.solido.money/) and follow these steps to open your Trove: 1. Navigate to the **"Mint $CASH"** section from the sidebar. 2. Enter the amount of tokens you wish to deposit as collateral. 3. The UI will display the maximum $CASH you can mint. Choose an amount within this limit (minimum mint: 20 $CASH). 4. Review the Trove details on the information panel. Note that: * A **liquidation reserve** of 2 $CASH is added to your debt. This is used to incentivize the liquidator and pay for gas fees. This is refundable to you upon closing your Trove. * A **one-time borrowing fee** is added to your total debt. 5. Click **Open Trove** and sign the transaction in your wallet. Once the transaction is confirmed, you’ll be redirected to the **Trove Dashboard**, where you can monitor your position and Loan-to-Value (LTV) ratio. > 💡 Tip: Click on the $CASH icon in the top nav bar to quickly import $CASH into StarKey. Alternatively, you can manually import it using the following contract details:\ > 0x9176f70f125199a3e3d5549ce795a8e906eed75901d535ded623802f15ae3637::cdp\_multi::CASH *** #### **Adjust Your Trove** After opening a Trove, you can manage it flexibly: * Go to the **"Mint $CASH"** section. If you already have a Trove, you’ll be taken to the Trove Dashboard. * Use the **Mint** tab to mint more $CASH or deposit additional collateral. * Use the **Repay** tab to repay your debt or withdraw collateral. #### **How It Works:** * Input values in either the mint/repay or deposit/withdraw fields. * Leave any field empty if you don’t want to modify that part. * Click **Update Trove** and sign the transaction. > Important: You **cannot** reduce your debt below the minimum allowed unless you fully close your Trove. *** #### **Close Your Trove** To close your Trove: 1. Go to the **"Mint $CASH"** section. If you have an open Trove, you’ll be redirected to the Dashboard. 2. Open the **Close Trove** tab. 3. Ensure your wallet holds enough $CASH to repay the entire debt (including fees). 4. Click **Close Trove** and sign the transaction. Upon closing: * Your **collateral** will be returned in full. * The **2 $CASH liquidation reserve** will be refunded. * Any $CASH you don’t already hold (e.g., minting fees) must be acquired externally—via another address or a DEX. *** #### **Liquidate Risky Troves** If a Trove exceeds the liquidation threshold (i.e., its LTV is too high), it becomes eligible for liquidation. By liquidating a Trove, you collect a liquidation penalty (currently 10%) that the liquidated Trove pays. #### **To liquidate:** * Go to the **Troves/Liquidation** page. * Troves are listed from riskiest (highest LTV) to safest. * If you hold enough $CASH and a Trove is eligible, a **Liquidate** button will appear. * Click **Liquidate** and sign the transaction to pay off the debt and claim the collateral (plus rewards). *** ## **Grow/ Stake $CASH** Grow operates through two simple actions: * **Stake** $CASH → Receive bCASH * **Unstake** bCASH → Redeem back $CASH (at the current exchange rate) *** **Staking $CASH** * Navigate to the **Earn $CASH (Grow)** section within the app. * Ensure your wallet is connected and your $CASH balance is visible. * Enter the amount of $CASH you want to stake, or use quick‑select. * Review the amount of **bCASH** you’ll receive. * Click **STAKE** and confirm the transaction in your wallet. * Your updated **bCASH** balance will be reflected in your portfolio. *** **Unstaking bCASH** * Switch to the **UNSTAKE** tab. * Enter the amount of **bCASH** you wish to convert back to $CASH. * The equivalent $CASH amount (based on the current exchange rate) will be displayed. * Click **UNSTAKE** and approve the wallet transaction. * Your $CASH will be credited back to your wallet. *** **How Rewards Work**\ When you stake $CASH, you mint bCASH, which represents your share of the Grow pool. Rewards don’t come as extra tokens; instead, the value of each bCASH gradually increases through the bCASH → $CASH exchange rate. Over time, this means 1 bCASH is worth more $CASH. Whenever you choose to unstake, you can redeem your bCASH back into $CASH at the current exchange rate. *** > ⚠️ **Notes:** > > * APY is variable and changes with market conditions. > * Unstaking is quick, but final amounts depend on the **current exchange rate**. > * Always keep a small amount of gas token for transactions. *** {% hint style="info" %} 💡 **Pro Tip:**\ There’s no need to claim rewards manually; they’re automatically reflected in the bCASH exchange rate. {% endhint %} *** *Risk Disclaimer: Please review the* [*disclaimers*](/solido/disclaimers/risks.md) *carefully and use Solido at your own risk.* --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
