Steem Keychain Mobile: Phase 5 — Browser & Keychain Bridge

kafio (75)in Steem Dev • yesterday

Hello everyone,

Following Phase 4 (Savings & Governance), I am sharing the most exciting update so far for Steem Keychain Mobile.

Phase 5 (Releases 20–23) introduces the in-app browser and the Keychain Bridge — you can now browse Steem dApps directly inside the wallet, and the bridge that lets dApps request transaction signing is now injected into every page. This is the phase that starts turning the wallet from a tool into a platform.

Note: I have also made some updates to the full roadmap post to keep it accurate and aligned with the current development progress.

Watch the demo:

What Is in Phase 5

R20 — Browser WebView

Full in-app browser with WebView — browse any website without leaving the wallet
Complete navigation controls: back, forward, refresh, stop
URL bar with real-time page title display
Loading progress indicator
Open any Steem dApp directly inside the wallet

R21 — Browser Tabs

Multi-tab browsing — open, switch, and close multiple tabs
Tab counter showing how many tabs are open
Tab overview screen with page previews
Each tab maintains its own browsing history and state

R22 — Browser Home Page

Home page with quick access to popular Steem dApps
Explore section — curated list of dApps and websites to discover
Favorites — save your most visited dApps for quick access
Browsing history — easily return to sites you visited before

R23 — Keychain Bridge

Keychain JS injection — the window.steem_keychain API is injected into every page loaded in the browser
dApps can detect the wallet and request transaction signing, just like the Chrome extension
Handshake support — dApps are notified that Keychain is available on page load
Active account info is shared with dApps automatically

What I Enhanced During Testing

Smooth navigation — Back, forward, and refresh work seamlessly across tabs
Tab persistence — Tabs maintain their state when you switch between them
Progress indicator — Visual loading bar so you always know when a page is loading
Home page design — Clean layout with explore, favorites, and history sections
Bridge compatibility — The injected bridge dispatches both mobile and extension-compatible handshake events so existing dApps work without modification
ConfirmDialog — Closing tabs or clearing history goes through confirmation
Toast feedback — Clear notifications when adding favorites or clearing history

What Is Coming Next — Keychain Requests (Phase 6)

The bridge is now injected. Next, the app will handle the actual requests that dApps send through it:

Request modal — approve, reject, and review dApp requests
Transfer requests — dApps can request transfers on your behalf
Vote & post requests — vote or post through dApps with one tap

Some parts of Phase 6 are already implemented, but there are still some operations that are not supported yet. I will be testing and completing them in Phase 6 and the following phases.

Current Roadmap Status

What I Need From You

Now it is your turn. The exciting features are here and more are coming. Please test the Phase 5 browser and share your feedback:

Open a few websites — Is the browsing experience smooth? Does navigation feel natural?
Try multiple tabs — Open 3–4 tabs, switch between them. Does everything stay in sync?
Use the home page — Are the explore suggestions useful? Can you add and remove favorites easily?
Check the history — Does it accurately show your browsing history?
Try Steem dApps — Open Steemit, SteemPro, or other platforms. Do they load and work correctly?
Share your thoughts on the UI/UX — What would you change? What would you add?

Your feedback directly shapes the next phases. Every suggestion matters.
