Each section leads with the value, then points you to a focused feature guide. No code here—follow the links to implement. ## Authentication Authenticate when it unlocks value, not before. Fast, optional sign‑in keeps momentum and lets users act the moment onchain interactions are needed. ## Wallets Enable onchain actions without getting in the way. Prompt progressively and avoid gates that block exploration. ## Manifest Your manifest powers saving, discovery, and rich embeds. A strong manifest includes complete fields, valid assets, and `noindex: true` during testing. ## Embeds & Previews Distribution starts in the feed: compelling previews with a clear image and launch button turn impressions into launches. ## Search & Discovery Be found across surfaces: set a primary category, share once to trigger indexing, and keep assets valid to appear in search and categories. ## Sharing & Social Graph Design for social lift: native share flows and social navigation turn single‑player moments into threads and returns. ## Notifications (coming soon) Re‑engage saved users with relevant, rate‑limited notifications at the right moments. ## UX Best Practices Build for compact, touch‑first contexts: respect safe areas, keep interfaces concise, and emphasize clear primary actions. ## Performance & load polish Perceived speed drives retention: target fast first paint, avoid layout shift, and minimize blocking work. ## Quality Bar Check Meet the standard for wide distribution: stable, instrumented, discoverable, shareable, and polished.
