Ethereum's Pectra upgrade activated on mainnet this morning, delivering one of the most consequential changes since The Merge. Layer 2 transaction fees have already dropped by roughly 80 percent across Base, Arbitrum, and Optimism. Developers are particularly excited about EIP-7702, which lets standard wallets temporarily behave like smart accounts. That unlocks gasless onboarding flows for new users, a long-standing pain point for consumer apps built on Ethereum.
