Crypto Lending: How to Earn Yield by Lending Crypto
Lending crypto means letting someone else use your coins in exchange for interest. The interest has to come from somewhere: borrowers who pay to use the funds. Understanding who those borrowers are, and what protects you if they do not repay, is the core of evaluating any crypto lending opportunity.
Three ways to lend crypto
1. DeFi lending pools
You deposit assets into a smart contract pool. Borrowers take loans from the pool against collateral, and the interest they pay is shared among lenders. Rates are usually set by utilization: the more of the pool is borrowed, the higher the rate. Your protection is the borrowers’ collateral and the protocol’s liquidation system.
2. Centralized lending platforms
You deposit with a company that lends your assets to its own borrowers. Yields can be simple to understand, but you depend on that company’s risk management and solvency. If it fails, you are an unsecured creditor.
3. On-chain credit and private credit pools
You fund loans to businesses, often fintechs or trading firms, through on-chain pools. Yields come from real-world business lending, and protection comes from underwriting, legal structures and sometimes collateral held off-chain. See our on-chain credit section.
Where the yield comes from
- Borrowing demand: traders borrowing for leverage, businesses borrowing for working capital.
- Utilization: in pool-based protocols, idle liquidity earns little, borrowed liquidity earns more.
- Incentives: token rewards paid on top of interest. These can disappear quickly and should not be confused with sustainable yield.
- Credit risk premium: loans with less collateral pay more because the lender takes more risk.
Risks lenders take
- Smart contract risk: a bug or exploit can drain a pool.
- Bad debt: if collateral cannot be liquidated in time, the pool absorbs the loss.
- Counterparty and default risk: in centralized and undercollateralized lending, the borrower or platform may not repay.
- Liquidity risk: when utilization is very high, you may not be able to withdraw immediately.
- Stablecoin risk: lending a stablecoin exposes you to that stablecoin keeping its peg.
How to evaluate a lending opportunity
- Identify the borrowers and why they pay this rate.
- Check what secures the loans: on-chain collateral, legal claims or nothing.
- Read the audits and check the protocol’s history of incidents.
- Separate base interest from temporary token incentives.
- Check withdrawal conditions and lock-up periods.
