Quick Answer

Moonwell is an open, non-custodial lending and borrowing protocol operating on blockchain networks like Base, Optimism, and Moonbeam. It allows users to supply crypto assets to earn yield or borrow against them, with all transactions recorded transparently on-chain. WELL is its governance token.

Moonwell is an open lending and borrowing protocol that lets you put your crypto to work, earning yield on what you supply or borrowing against it without selling. It is prominent on Base and also runs on networks like Optimism and Moonbeam, with WELL as its governance token.

This tutorial walks through the full flow: supplying assets, enabling collateral, borrowing, and managing risk. The goal is a practical, neutral guide so you understand each click and the mechanics behind it. This is educational content, not financial advice.

What Moonwell Is

Moonwell is a non custodial, onchain money market. That means you keep control of your assets through your own wallet, and every supply, borrow, and repayment is recorded transparently on the blockchain. There is no central party holding your funds.

The protocol works through shared liquidity pools. People who supply assets provide the liquidity that borrowers draw from. Borrowers pay interest, and that interest flows back to suppliers as yield. Smart contracts manage rates and collateral automatically, with key parameters set through Moonwell Governance.

When you supply, you receive interest bearing tokens that represent your share of a pool. Their value grows over time as borrowers pay interest, so your balance reflects both your deposit and accrued yield.

How to Supply (Lend) on Moonwell

Supplying is the first step. It earns yield and, once enabled as collateral, unlocks borrowing power. Before you begin, connect a Web3 wallet funded with the asset you want to supply and a small amount of the network gas token to cover fees.

Step by step

Connect your wallet. Visit the official Moonwell app and connect your wallet, making sure you are on the correct network, such as Base.
Choose an asset. Open the Markets section and select the asset you want to supply.
Enter the amount. Type the amount you want to supply, or click MAX to use your full available balance.
Click Supply. Confirm the action in the supply panel.
Approve the token. Click Approve Supply to grant the contract permission to use that token. This is a one time permission per asset.
Confirm in your wallet. Approve the transaction in your wallet to finalize the deposit.

Once the transaction confirms, your supplied balance appears in your dashboard and begins earning yield immediately.

Enabling Collateral

Supplying an asset does not automatically make it usable as collateral. To borrow against a supplied asset, you must enable it.

Find the asset in your dashboard and toggle the collateral switch to YES. This tells the protocol to count that asset toward your borrowing power. Important: collateral must be enabled individually for each asset, so repeat the toggle for every asset you intend to use as backing.

If you only want to earn yield and have no plans to borrow, you can leave the collateral toggle off. Assets not enabled as collateral still earn supply interest.

How to Borrow on Moonwell

Once you have supplied assets and enabled them as collateral, you can take out an over collateralized loan. Borrowing lets you access liquidity without selling your holdings.

Step by step

Click Borrow on the asset. In Markets, find the asset you want to borrow and click Borrow. This opens the Borrow page.
Enter the amount. Type the amount you wish to borrow. Stay well under your maximum limit to keep a safety buffer.
Click Borrow. Start the transaction from the Borrow page.
Review the details. Check the borrow amount, the rate, and how the loan affects your position before continuing.
Click Confirm Borrow. Approve the borrow action.
Confirm in your wallet. Sign the transaction in your wallet to receive the borrowed funds.

After confirmation, the borrowed asset arrives in your wallet and your outstanding debt appears in your dashboard, where it accrues interest over time.

The Over Collateralization Model and Interest Rates

Moonwell uses an over collateralized model. You can only borrow up to a percentage of the value of your supplied collateral, and that percentage is set per asset by Moonwell Governance. For example, if an asset carries a 75 percent collateral factor, supplying 1,000 USD of it allows borrowing up to roughly 750 USD of value in other supported assets.

Your dashboard shows how much borrowing capacity remains. Keeping that figure comfortably above zero is the core of staying safe. The closer you push toward your limit, the less room you have to absorb price swings.

How rates work

Interest rates on Moonwell are dynamic and adjust in real time based on market demand. When a large share of a pool is borrowed, rates rise to attract more suppliers and slow new borrowing. When utilization falls, rates ease. Suppliers earn from the interest borrowers pay, so supply and borrow rates move together with pool activity.

Loans have no fixed repayment schedule or maturity date. You can hold a loan indefinitely as long as your remaining borrowing capacity stays above the minimum required.

Optional Features: Moonwell Card and USDC Flows

Beyond core lending, Moonwell offers features that connect onchain balances to everyday use.

The Moonwell Card is a debit card that lets you spend onchain assets in the real world. You can load it in two ways. The simple method transfers USDC directly from your Base wallet balance. The borrow and load method lets you borrow USDC against your supplied collateral and load the card in one flow, which is useful if you prefer not to sell your holdings.

The Borrow USDC feature lets you borrow USDC against collateral on Base and send it across supported networks using Circle's Cross Chain Transfer Protocol. You enable collateral, choose USDC, select a destination network, enter an amount, and approve the transactions. Cross chain transfers are not instant and a small protocol fee may apply, so plan accordingly.

Risks and Liquidation Safety

Borrowing introduces liquidation risk, and understanding it is essential before you take on debt.

Maintain a healthy collateral ratio. Keep your remaining borrowing capacity well above the minimum. If the value of your collateral falls or your debt grows past the allowed limit, your position can be liquidated to repay the loan.
Account for volatility. Collateral made up of volatile assets can drop quickly. A conservative loan to value leaves a cushion against sudden price moves.
Monitor your position. Because rates are dynamic and prices change, check your dashboard regularly and repay or add collateral if your buffer shrinks.
Smart contract and oracle risk. Like any DeFi protocol, Moonwell carries smart contract and price oracle risk. Only commit funds you can afford to leave at risk.
Verify the official site. Always reach the app through the official domain and confirm transaction details in your wallet before signing.

Conclusion

Moonwell makes onchain lending and borrowing approachable: supply an asset, toggle it as collateral, then borrow within a safe limit. The over collateralized model and dynamic rates keep the system balanced, while features like the Moonwell Card and cross chain USDC extend what your position can do.

The practical takeaway is discipline. Borrow modestly, keep a healthy collateral buffer, and monitor your position so you stay clear of liquidation. With those habits, you can use Moonwell to earn yield and access liquidity while keeping full control of your assets.

Understanding Your Borrowing Power and Liquidation Risks Beyond the Basics

While the Moonwell interface provides a clear overview of your health factor and borrowing capacity, a deeper understanding of how these metrics fluctuate is crucial for advanced users. Your borrowing power isn't static; it's a dynamic value influenced by market volatility affecting both your collateral and the assets you borrow. A seemingly healthy health factor can deteriorate rapidly during periods of high price correlation or cascading liquidations across the broader DeFi ecosystem.

Consider the "liquidation threshold" not just as a single point, but as a zone. As your health factor approaches 1.0, the risk of partial or full liquidation increases exponentially. Liquidators are incentivized to act quickly, and even a momentary dip in your collateral's value or a spike in the borrowed asset's value can trigger the process. Proactive monitoring and strategic management of your loan to value (LTV) ratio are paramount, especially when dealing with volatile assets.

Advanced Risk Mitigation Strategies

Maintain a health factor significantly above the liquidation threshold, ideally 2.0 or higher, especially with volatile collateral.
Diversify your collateral types if possible to mitigate single asset price risk, though Moonwell's current design may limit this for individual loans.
Monitor the market sentiment and on-chain metrics for your specific collateral and borrowed assets, looking for early warning signs of price instability.
Be prepared to supply additional collateral or repay a portion of your loan quickly if market conditions shift unfavorably. Have stablecoins ready in your wallet.
Understand the oracle update mechanisms for Moonwell. Price feeds are not instantaneous and can lag during extreme market movements, creating windows of vulnerability.
