Overview
- Core developers confirmed on Wednesday that they are running private devnets containing the full Glamsterdam EIP bundle as the final development phase before hardening and public testnets.
- There is no fixed activation date but teams expect a mainnet launch in the second half of 2026 pending public testnet results and multi-client readiness.
- Enshrined Proposer-Builder Separation (EIP-7732) will put the builder–proposer split on-chain to reduce off-chain trust in relays and lower opportunities for maximal extractable value manipulation.
- Block-level Access Lists (EIP-7928) let a block declare which accounts and contract data it will touch so clients can preload state, which should speed execution and enable parallel processing when transactions do not overlap.
- A broad gas repricing will make heavy computation cheaper and persistent state storage more expensive, which will change contract design incentives and may affect validator economics and Layer‑2 compatibility.
