Borrowing
Borrowing in DeFi is the process of acquiring capital by providing collateral to a decentralized lending protocol. Users lock crypto assets into a smart contract to receive a loan in another asset. These protocols are typically over-collateralized, meaning the value of the deposited assets must exceed the value of the borrowed loan. This system allows users to leverage their positions or gain liquidity without having to sell their underlying assets.
Explain Like I'm 12
Borrowing in crypto is like a secured bank loan. You give the bank a valuable item, like a gold bar, and they let you borrow cash. If you don't pay it back, they keep your gold. In crypto, you lock your tokens to borrow other tokens.
Why It Matters
It allows users to access liquidity without creating a taxable event or losing exposure to their original assets. This is essential for capital efficiency and advanced trading strategies in Web3.
How It Works
The user deposits crypto into a lending pool. The protocol assesses the value and sets a loan-to-value ratio, allowing the user to borrow a percentage of the collateral value. If the collateral value drops below a certain threshold, the protocol may automatically liquidate the position to protect lenders.
Real-World Example
Aave, where users deposit ETH to borrow stablecoins like USDC for further investment or liquidity.
Advantages
- Access to liquidity
- Non-taxable capital usage
- Maintains investment exposure
Limitations
- Liquidation risk during volatility
- Over-collateralization requirements
- Variable interest rates
Common Misconceptions
- People assume DeFi borrowing involves credit checks.
- Many believe they don't lose their assets if the market crashes.

Related Terms
Collateral
Collateral refers to the assets that a borrower locks into a smart contract to secure a loan within a decentralized lending platform. Because DeFi protocols lack traditional credit scoring systems, they require assets of significant value to be deposited as security. If the borrower fails to meet the repayment terms or if the value of their collateral drops significantly, the protocol triggers a liquidation process to recover the debt and maintain the protocol's solvency.
Liquidation
The forced sale or seizure of collateral when a borrowing position no longer meets required collateralization.
Smart Contract
A smart contract is a self-executing program stored on a blockchain that automatically runs when predetermined conditions are met. These contracts eliminate the need for intermediaries by encoding terms directly into lines of code, ensuring that the agreement is enforced exactly as written without human interference. Because they reside on an immutable ledger, the execution results are verifiable, transparent, and impossible to tamper with once deployed.
Smart Contract
A self-executing program stored on a blockchain that automatically enforces and executes the terms of an agreement when predetermined conditions are met. Smart contracts are deterministic, immutable once deployed, and form the backbone of decentralized applications.
AMM
An Automated Market Maker (AMM) is a type of decentralized exchange protocol that relies on a mathematical formula to price assets instead of using a traditional order book. In an AMM, assets are pooled into smart contracts, known as liquidity pools, where traders interact with the pool rather than a counterparty. This infrastructure enables continuous liquidity and automated trade execution, removing the need for intermediaries such as market makers or centralized exchanges in the pricing and settlement process.
Arbitrage
Arbitrage is the practice of capitalizing on price discrepancies of the same asset across different exchanges or liquidity pools. In the context of blockchain, arbitrageurs monitor various DEXs and CEXs, identifying moments where a token’s price on one platform is lower than on another. By buying low on one platform and selling high on another simultaneously, the arbitrageur profits from the spread, while simultaneously helping to unify and stabilize asset prices across the entire ecosystem.
