Ethereum Foundation Designates FOCIL and Frame Transactions as Hegotá Must-Ships

Censorship Resistance and Account Abstraction

FOCIL is designed to give users a path to have eligible transactions included without relying on centralized block builders, strengthening Ethereum's resistance to transaction censorship. Frame Transactions would introduce native account abstraction and create a path toward post-quantum authentication.

The "must ship" designation carries real weight. The two proposals effectively define the upgrade, and if either is at risk, Hegotá's schedule should adjust before the proposal is dropped.

Tier Breakdown and Timeline

The Foundation's evaluation drew on input from roughly 60 researchers and engineers across the Protocol cluster. Beyond the two headliners, the Foundation placed 15 proposals in its A-tier, meaning they are expected to ship unless development or testing constraints force cuts. Another eight remain candidates for inclusion, seven were placed below the line but not ruled out, and 28 were declined.

This marks the first time the Foundation's Protocol cluster has published a unified view of proposed EIPs rather than separate opinions from individual teams. Client teams could begin implementing Hegotá in late 2026 following Glamsterdam.

Recent Context

Ethereum's last major upgrade, Fusaka, went live on December 3, 2025, bringing scaling and usability improvements to the network. Its headline feature, PeerDAS, changed how nodes handle rollup data, reducing the amount each node needs to download and upload while increasing data capacity for Ethereum layer-2 networks.
