Uniano Bridge

Connect Steam inventory and marketplace sessions to Uniano Terminal, with controlled support for agreed Steam trades.

Uniano Bridge connects signed-in Steam and supported marketplace sessions to Uniano for CS2 inventory synchronization and agreed peer-to-peer trades. INVENTORY AND MARKETPLACE SYNC - Import private Steam CS2 inventory when public sync cannot access it. - Refresh the Steam token used by Market.CSGO keep-alive and Waxpeer P2P. - Recover confirmed white.market CS2 purchases missing from the partner API. NEW IN VERSION 0.5.6: AUTOMATIC STEAM SESSION RENEWAL Bridge now keeps the Steam browser session fresh by itself. Every 30 minutes it checks the session once; before the Steam token expires, or when Steam signed the session out, it asks Steam's own login.steampowered.com to renew it, exactly as an open Steam page would. If that is not enough, one inactive Steam tab opens briefly and closes itself (at most once every three hours). The renewed token reaches Market.CSGO keep-alive and Waxpeer P2P without an open Terminal tab once you have signed in to Uniano. Bridge refuses to relay a token of a different Steam account than your Uniano and Market.CSGO account and says so in the popup. Cookies and tokens are still neither read nor stored; only renewal times and the token's Steam ID and expiry are kept locally. You sign in to Steam again only when Steam itself ends the long-lived login. VERSION 0.5.5: BOUNDED PURCHASE HISTORY OBSERVATIONS For a short-lived signed request from Uniano about a canonical unresolved purchase, Bridge can read the signed-in owner's newest English Inventory History page. It verifies the owner before and after the read and returns only a bounded structured minute and its boundaries. Uniano independently checks the exact official trade and current inventory. Raw HTML, Steam cookies, tokens and session IDs are not relayed or stored. The browser does not supply prices or settlement authority. Missing or ambiguous evidence stays unresolved. No additional hosts or permissions; Steam acceptance remains manual. VERSION 0.5.4: VERIFIED INVENTORY OWNER Before and after collecting each CS2 inventory context, Bridge checks which Steam account is signed in on Steam's own private trade-privacy page and relays only that account's Steam ID with the inventory. Uniano uses complete verified snapshots (tradable and trade-protected items) to tell that an item has really left the inventory; partial or unverified snapshots never cancel saved orders. Version 0.5.3 added fewer Steam requests: inventory, session-token and agreed trade requests share one paced queue, and an HTTP 429 pauses requests for Steam's retry delay across worker restarts. AGREED STEAM TRADES Native delivery is available only when enabled for your Uniano account. Installing or updating Bridge does not activate it by itself. Manual Buy now, Sell now and Bargain require price agreement and separate Ready confirmations from both participants in Portfolio. Each confirmation lasts five minutes. Delivery starts while both confirmations are current, the seller has a fresh Bridge connection and the buyer is available. Automatic matches use the consent already given when placing the matching Pending Buy and Pending Sell orders. No Ready confirmations or online buyer are required. The seller must have accepted the current trading policy and have a fresh supported Bridge connection; current account and Steam identity checks still apply. The buyer does not need Bridge. Both paths keep the original 24-hour request deadline while waiting to launch. Either participant may cancel before delivery starts. The single 15-minute delivery clock begins at launch and cannot be extended. After launch, Uniano cancellation is automatic; a nondelivery refund requires official Steam confirmation. Bridge creates or cancels offers only under an exact signed command for the agreed seller Steam account and CS2 item. Duplicate sends are blocked. The buyer always accepts the exact offer manually in Steam, with or without Bridge. Steam Guard remains a personal step. Installation alone does not activate native trading or start a trade. After signing in to Uniano, native commands run in the extension background without an open Terminal tab. Keep Chrome running and remain signed in to Steam and Uniano in the same profile. Chrome closure or computer sleep prevents execution. Market.CSGO/Waxpeer token refresh also runs in the background after signing in to Uniano; private inventory synchronization still requires an authenticated Terminal tab. The Steam desktop client and an open Steam tab are not required. Reload Uniano after installation or updating. Chrome 120 or newer is required. YOUR CONTROLS Click the toolbar icon to check status or pause all Bridge operations. The popup and Terminal share one switch. Pausing does not cancel existing orders. PRIVACY AND SECURITY Passwords and Steam Guard secrets are never read. Steam cookies and session IDs stay in Chrome. Own Steam Trade URL and a refreshed Steam token are sent through the authenticated Uniano session for encrypted account-bound storage. white.market tokens and receiver URLs are not sent to Uniano. Local storage holds settings, sanitized status, cooldown counters, preparation/retry timestamps, opaque dispatch markers for up to 24 hours, and background context: fixed Uniano origin, Steam ID, grant version and CSRF guard. Steam session renewal keeps only renewal times and the current token's Steam ID and expiry. It stores no Steam or white.market access tokens, cookies, passwords, balances, trade URLs or command payloads. Chrome attaches the existing HttpOnly Uniano cookie without exposing its value. Authentication failure or changed account/grant clears invalid context. The declarativeNetRequestWithHostAccess permission sets the required Steam request headers only for the exact signed trade POST issued by Bridge. Temporary rules are removed afterwards; normal website traffic is not modified. Official Steam records determine delivery and settlement; a timer or browser receipt alone never proves a refund. No advertising, unrelated tracking, remote executable code or sale of user data.
