Your savings account pays 3–4%. Stablecoins in DeFi earn 7–10% APY. Here are the only methods that are actually safe — and the dangerous ones that pretend to be.
Aave V3 on Arbitrum: 7.8% APY on USDC. Aave has $10B+ TVL, 20+ security audits, never been exploited. The lending model: your USDC is lent to overcollateralized borrowers. Industry-standard safety.
Kamino Finance on Solana: 7.2% APY on USDC. $2.1B TVL, audited by OtterSec and Halborn. Same model as Aave — lending to overcollateralized borrowers. Slightly higher execution risk (Solana chain) but excellent yield.
Curve Finance USDC/USDT pool: 5–8% APY. The safest DeFi yield — two stablecoins in one pool, near-zero impermanent loss, the most battle-tested protocol in DeFi (exists since 2020, never been exploited).
Red flags: Protocols promising 15%+ on stablecoins (likely Ponzi). Anonymous teams. New protocols with under $10M TVL. "Algorithmic stablecoins" (TerraUSD collapsed to zero in 2022). The rule: if you can't explain where the yield comes from, it's a risk.
