1. Where DeFi Lending Fits in the Larger Risk Map
If you need the broadest overview first, start with DeFi Risks. This page is narrower: it focuses on what happens once your strategy includes collateral, borrow balances, and protocol-level lending assumptions.
The two user profiles here are different. Lenders care about protocol quality, collateral quality, and stablecoin behavior because their capital is exposed to system stress. Borrowers care about the same things, but they also have an immediate personal exposure to liquidation.
That difference matters because many articles collapse both user types into one safety story. In practice the position you hold determines which risk becomes dominant first.
2. Health Factor and Liquidation Risk
The health factor is the core survival metric for borrowers. If your collateral value falls too close to your debt value, liquidators can repay part of your loan and seize collateral at a discount. This is the mechanism that protects lenders, but it is also the mechanism that punishes tight positions.
The main mistake is treating liquidation as a rare tail event. In reality, liquidation is an ordinary protocol function that activates exactly when collateral volatility, correlation shifts, or rapid market moves push your buffer too low. If you have not modeled that point, you are borrowing on intuition rather than structure.
Before borrowing or looping collateral, use the DeFi Health Factor Calculator to test how the position behaves when prices move against you. That is the fastest way to separate a workable setup from a fragile one.
Model liquidation before you borrow
If a DeFi strategy includes leverage, your first tool should be a health factor model rather than the dashboard APY.

Smart contract risk remains the base layer. You are trusting lending contracts, liquidation mechanics, and reserve accounting to behave correctly under stress. Audits help, but they do not convert code into certainty.
Oracle risk matters because collateral and debt values are only as good as the price feed the protocol sees. If the oracle is manipulated, delayed, or simply wrong at the wrong moment, the protocol can liquidate users incorrectly or fail to liquidate when it should.
Governance risk matters because token holders or protocol operators can still alter the rules around accepted collateral, borrow parameters, and emergency actions. A protocol can be technically solid while governance makes the risk profile worse over time.
4. Stablecoin and Collateral Risk
Stablecoin risk is often underestimated in lending because the supplied side feels calm until it does not. A stablecoin depeg can damage lenders directly and can also destabilize borrowing positions that depend on that asset holding close to one dollar.
Collateral quality matters just as much. Protocols that accept thinner, more reflexive, or more weakly distributed assets may offer attractive demand and yield, but they also make liquidation quality worse when the market is stressed. The protocol can still be "working" while the collateral being sold is simply not good enough.
If stable principal is central to the strategy, read Stablecoin Depeg Risk alongside this page. If you are chasing borrowed APY with farms or LPs, also read Yield Farming Risks.
5. Wallet, Address, and Token Risk Around Lending
Many DeFi lending losses do not begin inside the lending protocol at all. They begin with a fake front-end, a spoofed wallet address, an unsafe collateral token, or a copied address that was never verified.
If you are interacting with EVM protocol wallets, liquidity managers, or destination addresses, check them with the Address Risk Checker. If an unfamiliar token is part of the strategy, check it with the Token Risk Checker. If your workflow is Solana- or TRON-specific, use the chain-specific safety tools instead of assuming one checker fits all chains.
Check protocol-linked EVM wallets and destination addresses before sending funds.
Check unfamiliar collateral, reward, or farm tokens that interact with the lending workflow.
Use this for Solana wallets, token accounts, and program-related addresses.
Use this for TRON and TRC20 address checks before transfers or protocol interactions.
6. How to Stress-Test a Lending Position
Step 1: Model the health factor under a larger move than you expect. If the strategy only works under a calm tape, it is too dependent on market behavior staying friendly.
Step 2: Review the collateral set and ask what gets sold if the protocol enters stress. Good yield on weak collateral quality is not conservative lending.
Step 3: Evaluate the stablecoin itself, not just the protocol. If the supplied side, borrowed side, or LP side depends on a peg holding, that is part of the risk budget.
Step 4: Verify the addresses and tokens around the strategy before interacting. Operational mistakes and fake contracts are still a common way to lose funds even when the lending logic is sound.
Step 5: If the lending activity is part of a points campaign or rumored airdrop, use the airdrop interaction tracker to record which wallets completed each task and how much the strategy cost.
The cleanest mindset is to treat every lending position as a combination of price risk, protocol risk, and execution risk. Once you separate those, you can usually tell whether the APY is compensating you enough.
