DeFi TVL: Ethereum DeFi TVL is $50B+ (Feb 2026). If you're quoting numbers from 2023-2024, they're stale.
Uniswap V4 is live. Launched mainnet January 31, 2025 on 10+ chains. V4 introduced a hooks system — custom logic attached to pools (dynamic fees, TWAMM, limit orders, custom oracles). This is the biggest composability upgrade since flash loans. PoolManager addresses are different per chain (NOT deterministic like V3).
Costs changed everything: A flash loan arbitrage on mainnet costs $0.05-0.50 in gas now (was $5-50). This opens composability patterns that were previously uneconomical.
Ethereum 및 L2의 DeFi 레고 및 프로토콜 구성 가능성. 체인당 주요 프로토콜 — Aerodrome on Base, GMX/Pendle on Arbitrum, Velodrome on Optimism — 및 메인넷 프리미티브(Uniswap, Aave,Compound, Curve). 작동 방식, 이를 기반으로 구축하는 방법 및 결합하는 방법. DeFi 통합 구축, 특정 L2에서 프로토콜 선택, 수익 전략 설계 또는 기존 프로토콜을 새로운 것으로 구성할 때 사용하세요. 출처: austintgriffith/ethskills.
