The crypto market today is defined by Bitcoin's price stability near the $67,000 mark and massive anticipation for Ethereum's Glamsterdam upgrade. DeFi Performance: Sector outperformed with +5.3% average return vs. +3.7% overall market. Total Value Locked: $94.7B (+2.8% weekly), first growth week since mid-March. Uniswap: V4 hooks beta launching April 12. DEX volume: $8.9B weekly (-11% vs prior week). Arbitrum leads with $12.8B TVL. Base showing strongest growth: +18% monthly to $4.1B. The upgrade's centerpiece is EIP-7594, known as PeerDAS (Peer Data Availability Sampling). This allows network validators to verify large data blobs by sampling small pieces instead of downloading entire datasets, enhancing efficiency and decentralization. This is bullish for Ethereum because it makes using Layer-2 applications faster and significantly cheaper, which could drive higher adoption and network activity.
