DeFi Risk Terms for Beginners
Learn the difference between collateral, liquidation, smart-contract risk, oracle risk, and liquidity risk.
Risk words describe failure modes
DeFi vocabulary can feel abstract until you connect each term to a failure mode. Collateral risk asks whether a position has enough backing. Smart-contract risk asks whether the code can behave unexpectedly. Oracle risk asks whether outside price data can be wrong or manipulated.
A beginner does not need to memorize every protocol design. It is more useful to ask what can break, who controls the mechanism, and what happens when market prices move quickly.
Collateral and liquidation
Collateral is value posted to secure a loan or leveraged position. If the collateral falls too far relative to the borrowed amount, the system may liquidate the position to protect lenders or the protocol.
Terms such as health factor, collateral ratio, liquidation penalty, and margin all point to the same family of ideas: how much buffer exists before forced action begins.
Code, oracle, and liquidity risk
Smart-contract risk comes from bugs, incorrect assumptions, or unsafe interactions between contracts. Oracle risk comes from price feeds or data inputs. Liquidity risk appears when a position cannot be entered or exited without large price impact.
These risks often overlap. A liquidation system may depend on oracle prices, smart-contract execution, and available market liquidity at the same time.
How this appears in the game
A puzzle group might contain liquidation, collateral ratio, health factor, and liquidation penalty because they all describe forced-position risk. Another group might contain oracle manipulation, price impact, slippage, and liquidity because they describe market execution risk.
The game uses these groupings to make the vocabulary easier to compare, not to judge whether a protocol is safe.
