The Pectra hard fork significantly improves Ethereum’s user experience and developer flexibility. EIP-7702 introduces smart contract functionality to regular Ethereum accounts (EOAs), enabling users to batch multiple actions and manage gas fees more conveniently, moving Ethereum closer to account abstraction. EIP-2537 adds efficient cryptographic operations (BLS12-381 curve) to support advanced applications, and EIP-2935 provides easier access to historical block hashes, enhancing cross-chain interoperability and enabling future stateless client solutions.

For validators and stakers, Pectra introduces several enhancements. EIP-7002 allows execution-layer triggered validator withdrawals, boosting security and flexibility for staking pools. EIP-7251 raises the maximum effective validator balance from 32 ETH to 2,048 ETH, enabling large stakers to consolidate nodes and optimize efficiency. EIP-6110 streamlines validator deposits by processing them directly on-chain, significantly reducing activation times. Additionally, EIP-7549 and EIP-7685 optimize consensus mechanisms and enhance validator operations and communications between Ethereum's execution and consensus layers.

Pectra advances Ethereum’s scalability and supports rollup ecosystems EIP-7623 reprices transaction calldata, encouraging rollups to utilize cheaper blob storage, reducing mainnet congestion. EIP-7691 increases blob throughput, effectively doubling the data Ethereum can handle per block, leading to lower fees and better Layer-2 performance. Complementing these updates, EIP-7840 improves the configuration management of blob data, offering greater flexibility for future scalability enhancements.
