Ethereum developers release Pectra client software for Holesky & Sepolia ahead of April mainnet upgrade.

Ethereum core developers released Pectra-compatible client software for the Holesky and Sepolia testnets as the final preparation step before the upgrade’s planned mainnet activation in April 2025. Pectra is the combined Prague/Electra hard fork, an 11-EIP package focused on improving validator operations, wallet functionality, and scaling-related infrastructure, and the testnet releases were meant to let node operators and validators verify their software before mainnet. The broader context is that Pectra had already gone through a difficult rollout: early testnet activations hit issues on Holesky and Sepolia, prompting further testing and eventually a new testnet, Hoodi, before Ethereum set a firm mainnet date for May 7, 2025. The upgrade matters because it changes validator staking rules, introduces account-abstraction-style features through EIP-7702, and supports Ethereum’s longer-term scaling roadmap, so client readiness on testnets was a necessary checkpoint for a smooth mainnet fork.
