# Upcoming Features

> Planned Base protocol features and their ballpark target quarters, tracked independently of a specific network upgrade.

This page lists Base protocol features that are planned or in development, independent of the named upgrade that eventually ships them. Each entry links to its specification where one exists.

<Note>
  Targets are ballpark quarters and may change. A feature moves onto a named upgrade page (for example, [Cobalt](/upgrades/cobalt/overview)) only once that upgrade is scheduled and locked in, at which point the official activation dates and final feature list are published.

## How Features Ship

1. **Proposed** — a feature is designed and, where applicable, written up as a specification. It appears in the table above with a ballpark target.
2. **Scheduled** — once an upgrade that carries the feature is locked in, a named upgrade page is published with official Base Sepolia and Base Mainnet activation dates.
3. **Live** — the upgrade activates and moves to the [Upgrades](/upgrades/overview) timeline.
