Decentralized Finance (DeFi) has transformed the way individuals manage and grow their digital assets. One of the most trusted platforms in this space is Compound Finance, often referred to as the "decentralized bank" of the crypto world. With its transparent, blockchain-based lending and borrowing system, Compound enables users to earn passive income on their cryptocurrency holdings — all without relying on traditional financial institutions.
In this guide, we’ll walk you through how to connect your wallet, interact securely with the platform, and start earning yield on your assets using Compound Finance. Whether you're new to DeFi or expanding your investment strategy, this step-by-step tutorial ensures a smooth and secure experience.
Connecting Your Wallet to Compound
The first step in using Compound Finance is connecting your cryptocurrency wallet. For this example, we’ll use Wallet3, a secure, open-source wallet that supports seamless DApp integration.
👉 Start earning yield on your crypto assets today with a trusted DeFi platform.
Begin by visiting the official Compound website: https://app.compound.finance. Once loaded, you’ll see a list of supported tokens — these are the digital assets you can deposit to earn interest.
At the top-right corner of the page, click “Connect Wallet” or “No Account”, depending on your current status. From the options shown, select WalletConnect. A QR code will appear on your screen.
Now, switch to the Wallet3 app on your device and tap the “Connect DApp” button. The app will activate its camera to scan the QR code displayed on your browser.
Note for macOS Users: If this is your first time using Wallet3 with screen access, you may need to grant screen recording permissions. Go to System Preferences > Security & Privacy > Privacy > Screen Recording, and enable access for Wallet3. After restarting the app, it will be able to scan QR codes from your screen. Windows users do not require this extra step.
Wallet3 is fully open-source, meaning its code is publicly auditable. This transparency ensures no hidden functions or data leaks, giving users full confidence in their privacy and security.
Once the QR code is scanned, Wallet3 will prompt a connection request. Tap “Authorize” to establish a secure link between your wallet and Compound Finance.
You’re now connected and ready to begin interacting with the protocol.
Interacting with Compound: Deposit and Earn Interest
With your wallet connected, return to the Compound interface. Let’s use Dai (DAI), a popular stablecoin pegged to the US dollar, as our example asset.
Click on Dai to view its current market details. You’ll see two key metrics:
- Supply APY (Annual Percentage Yield): Currently at 2.58%
- COMP Rewards APY: An additional 1.58% in COMP tokens
This means you can earn a total return of over 4% annually — significantly higher than most traditional savings accounts — simply by depositing your Dai into the protocol.
Understanding COMP Tokens
COMP is Compound’s native governance token. By earning COMP, users gain voting rights in the platform’s decentralized decision-making process, such as proposing or approving changes to interest rates, collateral factors, and more. While governance isn’t required to earn interest, holding COMP adds long-term value and community influence.
To begin, click “Enable” next to the Dai market. This triggers an approval transaction, allowing Compound to access your Dai balance.
Authorizing Asset Usage Safely
Authorization is a critical security step when using any DeFi protocol. It involves sending a blockchain transaction that grants permission for Compound to use your assets.
👉 Securely authorize your assets and start earning high-yield returns in minutes.
Here’s what to watch for:
- Always check the spending limit during authorization.
- By default, many wallets allow unlimited access — which means if the DApp is compromised, all your funds could be at risk.
- To minimize risk, especially with newer or less-audited protocols, set a specific spending cap (e.g., 10,000 DAI).
In this case, since Compound is one of the oldest and most audited DeFi platforms — live since 2019 with no major exploits — granting unlimited access is generally considered safe. However, setting a fixed limit like 10,000 DAI provides peace of mind without sacrificing functionality.
After adjusting the limit (if desired), confirm the transaction using your wallet’s authentication method (such as Touch ID). Wait for blockchain confirmation — this may take a few seconds to minutes depending on network congestion.
Once confirmed, you’ll see the “Supply” button become active.
Supplying Assets and Earning Yield
Now it’s time to deposit. Enter the amount you’d like to supply — for example, 500 DAI — then click “Supply”.
Wallet3 will display a contract interaction dialog summarizing the transaction. Review the details carefully, then confirm using biometric authentication or your private credentials.
Once confirmed and processed on-chain, your 500 DAI begins earning interest immediately. Interest accrues every second and is distributed directly to your wallet in real time.
Withdrawing is just as simple: return to the Compound dashboard, navigate to your supplied assets, and select “Withdraw”. Confirm the transaction through Wallet3, and your funds — plus accumulated interest — will be returned to your wallet.
All transactions are recorded immutably on the Ethereum blockchain, ensuring full transparency and auditability.

Frequently Asked Questions (FAQ)
Q: Is Compound Finance safe for beginners?
Yes. While DeFi carries inherent risks like smart contract vulnerabilities, Compound is among the most secure protocols due to extensive audits, long-term operation, and community trust. Beginners should still practice caution — use spending limits and avoid sharing private keys.
Q: Can I lose money using Compound?
While earning interest is low-risk, potential losses can occur from:
- Smart contract bugs (rare but possible)
- Flash loan attacks (mitigated by protocol design)
- Market volatility (especially when borrowing)
Always do your own research before depositing funds.
Q: How often is interest paid on Compound?
Interest accrues continuously — every block (approximately every 12 seconds on Ethereum). Your balance increases automatically over time without needing manual claims.
Q: What happens if I forget my wallet password?
Since wallets like Wallet3 are non-custodial, there’s no recovery option if you lose access. Always back up your seed phrase securely offline.
Q: Are there gas fees when using Compound?
Yes. All transactions on Ethereum require gas fees. These vary based on network traffic. Consider using Layer 2 solutions or timing transactions during low-congestion periods to reduce costs.
Q: Can I borrow assets from Compound?
Absolutely. If you supply collateral (like DAI), you can borrow other supported assets against it. This enables strategies like leveraged positions or liquidity provision elsewhere.
