Frequently Asked Questions

What is the safest stablecoin DeFi strategy for beginners?

Aave V3 stablecoin supply markets offer the best combination of safety and accessibility for new users. With $6.2 billion TVL, zero major exploits since 2020, and an intuitive interface, new DeFi participants can earn 4–5% APY with minimal technical complexity. Start with small amounts (under $1,000) to understand gas costs and withdrawal timing before committing larger capital.

How do I calculate real net APY after fees and gas costs?

Subtract 1–2% for gas costs on Ethereum mainnet transactions (approximately $15–30 per transaction). For protocols like Yearn, factor in the 20% performance fee on profits. The formula is: Net APY = (Gross APY × 0.98) - (Annual Gas Fees / Principal). On L2 networks like Arbitrum or Optimism, gas costs drop to $0.50–$2 per transaction, making smaller deposits viable with net APY only 0.2–0.5% lower than gross figures.

Should I use single or multi-protocol allocation for stablecoin farming?

Diversification across 2–3 protocols reduces smart contract risk while capturing different.
