How to earn yield on stablecoins, and what can go wrong
Where stablecoin yield comes from, how to compare lending markets and vaults by rate and risk, and how to put idle USDC to work without taking risks you can't see.
Updated Nov 8, 2026
In short
Stablecoins earn yield when you lend them: on a lending market such as Aave, or in a vault such as Morpho's that lends them on for you. The rate comes from borrowers, sometimes topped up with reward tokens. Compare rates by where they come from, not only their size, prefer large and long-running markets, and spread deposits so one problem can't take everything. Every deposit carries the protocol's smart-contract risk, and a stablecoin can lose its peg.
Stablecoins sitting in a wallet earn nothing. Lending them out can earn a steady rate, but the yield always comes with risks, and the highest number on a page is rarely the best choice.
Where the yield comes from
- Lending markets, such as Aave: you supply USDC, borrowers pay interest, and you get a share. The rate follows how much is borrowed.
- Vaults, such as Morpho's: a curator spreads your deposit across lending markets for you, within rules the vault publishes.
- Rewards: some protocols add their own tokens on top. That part of the rate depends on the reward token's price, and usually doesn't last.
Compare rates properly
For each option, look at:
- How much is protocol yield and how much is rewards. Rewards can vanish.
- How much is deposited. Larger pools are usually more established and harder to move with one withdrawal.
- How long the protocol has been running, and its audits.
- Which chain it's on. Moving there costs a bridge and gas, and adds that chain's risks.
The risks
- Smart contracts: a bug or exploit in the protocol can lose deposits.
- The peg: a stablecoin can trade below a dollar if confidence in what backs it falls.
- Getting out: if a market is fully borrowed, withdrawing may have to wait until borrowers repay.
- Curators and governance: a vault's or protocol's settings can change.
Spreading deposits across protocols and stablecoins limits how much any one problem can cost.
In Burokku
The Yield finder looks at what you already hold and finds single-token deposits for each token, with the rate split into what the protocol pays and what's paid in rewards, the amount deposited, and risk notes in plain language. Filter to pools with $1M+ deposited or to chains you already hold the token on. From there you can deposit into Morpho vaults Morpho lists, signed in your own wallet, and your deposits show in your net worth and your tax report.
Questions
- Why do rates change every day?
- Lending rates follow demand: when many people borrow a stablecoin, lenders earn more, and when borrowing falls, so does the rate. Reward tokens also change in price and amount.
- Are pools that pair two tokens a good idea for stablecoins?
- A pool of two stablecoins has little impermanent loss while both hold their peg, but pools that pair a stablecoin with a volatile token can lose value against simply holding. Burokku's yield finder only suggests single-token deposits for that reason.
- Is this financial advice?
- No. This explains how stablecoin yield works and the risks to weigh. Where to put your money is your decision.
