Product Guide
Your go-to guide to get started with Solido Cash.
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 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 for the latest information and supported markets. Once purchased, transfer your $SUPRA to your StarKey Wallet.
Alternatively, you can buy $SUPRA using Dexlyn, a decentralized bridge and exchange built on the Supra blockchain. No KYC is required. Here’s how:
Using Dexlyn:
a. Visit the Dexlyn 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 PeriodAfter 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 and follow these steps to open your Trove:
Navigate to the "Mint $CASH" section from the sidebar.
Enter the amount of tokens you wish to deposit as collateral.
The UI will display the maximum $CASH you can mint. Choose an amount within this limit (minimum mint: 20 $CASH).
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.
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:
Go to the "Mint $CASH" section. If you have an open Trove, you’ll be redirected to the Dashboard.
Open the Close Trove tab.
Ensure your wallet holds enough $CASH to repay the entire debt (including fees).
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.
Risk Disclaimer: Please review the disclaimers carefully and use Solido at your own risk.
