Collateral Ratio Vulnerability
Collateral ratio vulnerability refers to the risk that a user's collateral value drops below the required threshold, triggering a forced liquidation. In lending protocols, users must deposit more value than they borrow to protect the lender.
If the price of the collateral asset falls, the collateral ratio decreases, and the protocol may liquidate the position to recover the debt. Attackers often try to manipulate the price of the collateral asset downwards to trigger these liquidations prematurely.
This allows the attacker to profit from the liquidation fees or by purchasing the liquidated collateral at a discount. Maintaining accurate price feeds is critical to prevent such malicious liquidations.
Glossary
Volatility Clustering
Analysis ⎊ Volatility clustering, within cryptocurrency and derivatives markets, describes the tendency of large price changes to be followed by more large price changes, and small changes by small changes.
Price Oracle Manipulation
Manipulation ⎊ Price oracle manipulation represents a systemic risk within decentralized finance (DeFi), involving intentional interference with the data feeds that provide price information to smart contracts.
Flash Loan Exploits
Exploit ⎊ Flash loan exploits represent a sophisticated attack vector in decentralized finance where an attacker borrows a large amount of capital without collateral, executes a series of transactions to manipulate asset prices, and repays the loan within a single blockchain transaction.
Collateralized Debt Positions
Collateral ⎊ These positions represent financial contracts where a user locks digital assets within a smart contract to serve as security for the issuance of debt, typically in the form of stablecoins.
Risk-Weighted Assets
Capital ⎊ Risk-Weighted Assets, within cryptocurrency and derivatives, represent a regulatory requirement for financial institutions to maintain capital reserves proportional to the riskiness of their holdings, encompassing both on-chain and off-chain exposures.
Protocol Design Flaws
Vulnerability ⎊ Protocol design flaws represent fundamental errors in the logical architecture or mathematical models governing decentralized financial systems.
Arbitrage Opportunities
Action ⎊ Arbitrage opportunities in cryptocurrency, options, and derivatives represent the simultaneous purchase and sale of an asset in different markets to exploit tiny discrepancies in price.
Decentralized Risk Governance
Governance ⎊ Decentralized risk governance refers to the process by which a decentralized autonomous organization (DAO) manages the risk parameters of a protocol.
Liquidation Auction Dynamics
Action ⎊ Liquidation auction dynamics represent the procedural steps undertaken when a collateralized position falls below a predetermined threshold, triggering a forced sale to cover outstanding obligations.
Dynamic Interest Rates
Mechanism ⎊ Dynamic interest rates in decentralized finance refer to lending and borrowing rates that automatically adjust based on the real-time supply and demand for a specific asset within a liquidity pool.
