Modern DeFi has transitioned from high-risk algorithmic yield farming to institutional-grade lending, automated market making (AMMs), and liquid staking protocols (such as Lido and EigenLayer), allowing users to earn yield while maintaining asset liquidity.Crypto x AI Synergy: Artificial intelligence and blockchain tech are rapidly converging. Autonomous AI agents utilize decentralized rails for micro-payments, compute power allocation, and trustless data verification.User Experience (UX) and Account Abstraction: Early crypto required manual seed-phrase management and complex wallet interaction. Modern protocol design leverages account abstraction, allowing social logins, gasless transactions, and seamless passkey authentication to onboard non-technical users.
