Steem Keychain Mobile: Phase 9 — Advanced Operations & Authority Management

kafio (75)in Steem Dev • 3 days ago (edited)

Hello everyone,

Following the Developer Docs Launch, I am sharing the next milestone for Steem Keychain Mobile.

Phase 9 — Advanced Operations & Authority Management — 7 new operations are now fully supported on mobile. Conversions, account creation, account imports, and the most security-critical operations on Steem: authority management.

What's New in Phase 9

Conversions

Convert your SBD to STEEM directly from your mobile device. The confirmation screen clearly explains the 3.5-day wait period and the median price mechanism — we respect Steem's core mechanics and make sure the user understands them before confirming.

Account Creation

Create new Steem accounts for other users using your claimed account creation tokens. The confirmation screen shows all 4 keys clearly:

Owner — The master key
Active — The wallet key
Posting — The social key
Memo — The encryption key

One tap from a dApp, the wallet handles everything securely.

Authority Management (The Danger Zone)

This is the most critical part. Authority operations grant or remove control over your account. Because of how dangerous these are, I built strict visual warnings into every screen:

Add Account Authority — Grant another account permission to act on your behalf. Red danger banner: "Warning: You are granting control...". Requires active key.
Remove Account Authority — Revoke an account's permission. Yellow warning banner.
Add Key Authority — Add a new public key (STM...) to your account. Requires active key.
Remove Key Authority — Remove a public key from your account.

Every authority screen forces the user to see exactly what they are signing. No hidden approvals, no silent grants.

Account Import

A dApp can now ask Steem Keychain Mobile to import a new account into the local wallet. This is not a broadcast — no transaction goes to the blockchain. The keys are transferred securely from the dApp into the user's encrypted Keychain storage.

This completes the onboarding flow: a dApp creates an account → immediately hands it to Keychain for safekeeping.

Why This Matters

Until now, these advanced operations were only available on desktop. Mobile users had no way to manage authorities, create accounts, or convert SBD from their phone.

Now they can. Every operation works through the same secure flow — a dApp sends a request, the wallet shows a clear confirmation screen with warnings, and the user decides.

For dApp developers: You can now build complete onboarding flows. Create an account, import it into Keychain, and delegate SP — all from mobile with deep links or the in-app browser.

For users: Your account security is visible. Red banners for dangerous operations, yellow for caution. You always know what you are signing.
