Contributions on Steem4Poker

Steem4Poker is a poker engine acquired and operated by @xpilar. I have been assisting with the Steem blockchain integration, as well as providing ongoing support and maintenance in exchange for compensation.

After gathering valuable reviews and feedback from users like @xpilar and @steemchiller, we updated several UI references and backend objects to improve the overall platform experience.

Below is a summary of my contributions so far. To accelerate development, I leveraged AI (specifically Grok) to assist with roughly 90% of the coding and implementation process.

🛠️ Technical Contributions

1. Steem Posting-Key Login (Mobile & Desktop)

• Added Posting Key login alongside Keychain (utilizing the same challenge → sign → verify flow).
• The client signs with the posting WIF via dsteem; the key is never sent to the server.
• The WIF is held only in an uncontrolled input or short-lived variable and is immediately cleared upon submit, method switch, unmount, or error.
• This feature is fully available on both desktop and mobile (not limited to mobile-only).
• Updated the Connect panel for wallet linking to support this dual-method approach.
• Implemented a tab-scoped sessionStorage flag for the login method (stores the method name only, not the key).

2. Deposit UX for Posting-Key Sessions

• If a user logs in with a posting key, the Keychain deposit button and popups are disabled.
• Switched to memo-only instructions: users are prompted to send funds to the deposit account with a unique personal memo.
• Confirmed that memos are unique per user (ensuring stable STEEM-MEMO deposit codes).

3. Deposit Monitor Reliability

• Root Cause: The cursor was getting stuck on an old SDS synthetic transfer outside the 3-day chain lookback window, blocking the queue.
• Fix: Extended the chain lookback to cover the cursor / oldest SDS row.
• Resolution: Successfully credited stuck deposits (e.g., 50 STEEM to @mamun123456 and 10 STEEM to @xpilar).

4. Play Money → PokTests Branding

• Renamed virtual/play currency displays to PokTests (updated amounts, formatters, and admin labels).
• Updated Lobby mode tabs to: Real Money | Free Play (instead of using "PokTests" as the tab name).
• Free Play stakes and buy-ins now format correctly as PokTests (live formatting rather than hardcoded STEEM strings).
• Fixed formatting spacing: now displays as PokTests 100.000 instead of PokTests100.000.

5. Admin: Grant PokTests

• Restored the VIRTUAL parameter on the balance adjustment API/service (the UI already had it, but the backend had dropped it).
• Admins can now ADD or REMOVE any PokTests amount via the Balance Adjustment tool.

6. Table Edit "Modified by Another Admin" Bug

• The optimistic updatedAt lock was triggering false positives (e.g., during pauses or style changes).
• Softened the logic to "last-write-wins" with skew logging, ensuring that Practice (Free) tables can be edited without errors.

7. Resolved Browser Cache & React removeChild Errors

• Issue: Dual React bundles (from index.js?v=… vs. imports without query strings) were causing DOM removeChild errors.
• Fix: Unified the build on index-fp2.js (single module graph, no query strings).
• Updated index.html Cache-Control to no-store so users automatically pick up the new shell without needing a manual cache clear.
• Softened long-lived immutable JS caching and provided troubleshooting guidance for stuck users (use incognito, hard refresh, or clear site data).

8. Tournament Scheduling & Auto-Start

• Fixed the Admin Start Time picker to use the local timezone (previously, it was incorrectly feeding UTC into datetime-local).
• Bug Fix: Debugged an issue with 2500-chip tournaments where the Admin Start button only set the status to RUNNING without creating tables.
• Admin Start now uses a proper flow: start → creates tables + seats players.
• Tournament tables are now properly registered in memory after creation.
• Implemented a Lifecycle cron (every 30s) to auto-start when the time is right and minimum players are met, and to auto-cancel underfilled past-start registrations.

9. Claim 500 PokTests (Cashier)

• Added a Cashier Deposit feature: Claim 500 PokTests, limited to once per rolling 24 hours.
• API: Added GET/POST /api/v1/cashier/virtual-chips/claim-status & claim.
• UI: Filled out the Steem plugin UI and added a cooldown countdown on the claim button.
