FAQ
Are DeFi apps safe to use in 2025?
Many DeFi protocols undergo audits and offer bug bounty programs, but risks remain. The most established protocols, such as Aave, Lido, and Curve, have proven track records; however, always do your own research and manage exposure smartly. Start with small amounts and gradually increase as you gain experience.
Can beginners use DeFi tools?
Some apps like Lido or Yearn are user-friendly with clear interfaces, but others may require technical knowledge. Use trusted interfaces, follow official guides, and start with simple strategies before exploring complex features. Many protocols now offer educational resources and community support.
What are the main costs of using DeFi apps?
Expect network gas fees (varies by blockchain), protocol fees (typically 0.1-2%), and potential slippage on trades. Layer 2 solutions, such as Polygon, offer significantly lower costs. Consider transaction costs when planning strategies, especially for smaller amounts.
How do I choose between different DeFi strategies?
Consider your risk tolerance, technical expertise, and investment timeline. Conservative users should focus on established protocols, such as Lido staking or Aave lending. More experienced users can explore yield farming, liquidity provision, or automated strategies through Yearn Finance.
