Delta developer platform
Delta Game SDK
A permission-gated bridge for platform features inside sandboxed games.
Cloud save
Games request cloud.save permission. Writes are authenticated by the host, validated server-side, and use optimistic versions to prevent overwrites.
const save = await Delta.storage.get("campaign");
await Delta.storage.set("campaign", { level: 4, coins: 120 });Scores and achievements
Client submissions are never inherently trusted. Ranked games should attach a server-verifiable proof or use an authoritative room.
await Delta.leaderboard.submit("best_time", 9820, signedProof);
await Delta.achievements.unlock("first_run");
