Can I earn yield on stablecoins?

Yes — stablecoins are actually one of the most common places people put idle cash to work in crypto. The yield usually comes from one of a few routes:

On centralized exchanges — most major CEXs pay a small yield on idle stablecoin balances (often 1–5% APY, no lockup, withdrawn anytime). This is the simplest route but involves counterparty risk: the exchange holds your funds, and you're trusting them not to fail (e.g. FTX).

DeFi lending — the classic model. You deposit a stablecoin (USDC, USDT, DAI) into a lending protocol (Aave, Compound, etc.), and it's lent out to borrowers who pay interest. Rates float with supply and demand — they can be ~2% one week and double-digit the next. Higher rates generally mean more borrowing demand, not more safety.

Stablecoin yield pools — vaults/strategies that deploy your stablecoin across lending markets and other yield sources, often auto-compounding. Higher headline APY here usually means more protocol/impermanent/strategy risk, so the number alone isn't the whole story.

The catch worth knowing: stablecoin yield isn't "free money." It's compensation for real risk — the stablecoin issuer's own backing (is USDC's $1 actually real?), the platform's credit/counterparty risk, and in DeFi, smart-contract risk. An unusually high APY (15%+, sometimes far more) is a red flag rather than a gift; stablecoin yield is ultimately a lending market, and market rates don't get that high without added risk. Also watch for yields quoted as "APR vs APY" and whether they're compounding.

If you want, I can pull up current options — either the lending protocols ranked by actual daily fee revenue (real usage data per DefiLlama), or a list of exchanges that support stablecoin earning where you could compare them directly. Which would help more?
