Liquidation protects lenders from losses but can result in significant capital loss for borrowers, especially during rapid market downturns or cascading liquidation events.

​
Layer 1 (L1)

A Layer 1 blockchain is the base network that processes and validates transactions directly, such as Bitcoin or Ethereum.

​
Layer 2 (L2)

A Layer 2 solution is a scaling technology built on top of a Layer 1 blockchain to increase transaction throughput and reduce fees.

​
Liquidity

Liquidity refers to how easily an asset can be bought or sold in a market without significantly affecting its price.

​
Looping / Looping Risk

Looping is a DeFi strategy where a user borrows an asset, re-deposits it as collateral, and borrows again — repeating the cycle to amplify yield. This creates leveraged exposure and increases the risk of liquidation cascades if the collateral value drops.

​
Liquidity Pool

A liquidity pool is a pool of digital assets locked in a smart contract to facilitate decentralized trading, lending, or other financial activities.

​
Liquidity Risk Monitoring

Liquidity risk monitoring is the ongoing analysis of the availability and stability of liquidity for a digital asset across trading venues, pools, and markets. Monitoring liquidity helps identify conditions such as sudden liquidity withdrawals, concentration risks, or abnormal trading activity that may impact price stability.

​
MEV (Maximal Extractable Value)

Maximal Extractable Value (MEV) refers to profits that block producers can generate by reordering, inserting, or censoring transactions before they are finalized on the blockchain.

​
Miner

A miner is a participant in a proof-of-work blockchain who uses computational power to validate transactions and create new blocks.

​
Mixer (Tumbler)

A crypto mixer is a service that attempts to obscure the origin and destination of digital assets by combining transactions from multiple users.

​

​
Total Value Locked (TVL)

Total Value Locked (TVL) represents the total USD value of assets deposited in a DeFi protocol, vault, or liquidity pool. TVL is a key indicator of protocol adoption and trust. In vault risk assessment, low TVL (under $50k) indicates higher risk due to less battle-testing and easier price manipulation.

​
Utilization Rate

Utilization rate is the percentage of a lending pool’s total deposits that are currently borrowed. High utilization (above 95%) means most capital is lent out and depositors may not be able to withdraw. In vault risk assessment, high utilization is a key liquidity signal.

​
Transaction

A transaction is a transfer of digital assets or data recorded on a blockchain.

​
