Quick Definition

A financial service allowing users to lend their cryptocurrency to borrowers in exchange for interest payments, available through both centralized and decentralized platforms.

What Is Crypto Lending?

Crypto lending enables cryptocurrency holders to earn yield on their digital assets by lending them to borrowers who pay interest. This mirrors traditional banking but operates in the crypto ecosystem, with loans typically overcollateralized — borrowers must deposit more value than they borrow to protect lenders against default.

Centralized lending platforms (like BlockFi, historically) operate similarly to banks, pooling lender deposits and managing loan origination. Decentralized lending protocols (like Aave and Compound) use smart contracts to automate the entire process, with interest rates determined algorithmically based on supply and demand for each asset.

The appeal of crypto lending includes potentially higher yields than traditional savings accounts, the ability to borrow against crypto holdings without selling (avoiding taxable events), and providing leverage for trading. However, the space carries significant risks: smart contract vulnerabilities, liquidation during market crashes, regulatory uncertainty, and platform insolvency. The collapse of Celsius, BlockFi, and Voyager in 2022 wiped out billions in depositor funds, underscoring that high yields often correlate with high risk.

Crypto Lending Example

  • 1An investor deposits 10 ETH into Aave's lending pool, earning a variable APY of 3.5%. The protocol automatically lends these ETH to borrowers who have deposited collateral worth at least 150% of their loan value, with smart contracts handling all interest calculations and liquidations.
  • 2A Bitcoin holder needs $50,000 for a home renovation but doesn't want to sell their BTC (avoiding capital gains tax). They deposit 2 BTC as collateral on a lending platform and borrow $50,000 in USDC at 8% APR, repaying the loan over 12 months while retaining their Bitcoin exposure.
