Features

Values in place

Every item in a trade carries its value and a USD estimate, with offer totals and the difference between both sides.

Trade previews

Every trades list, from Inbound to Inactive, shows what each offer is worth before it is opened, and flags items that have no value yet.

Inbound trade alerts

New inbound trades can reach Discord, the ntfy app or a desktop notification, filtered by value or gain. Only the trader's name, the items and their values are sent.

Outbound trade tools

RoLens finds outbound trades that can no longer complete and cancels them one at a time, only after you review and confirm the exact list.

Trade proofs

A completed trade becomes a shareable image with both sides, every value and the net result, drawn entirely on your device.

Nothing without your say

RoLens never sends, accepts or counters a trade and never acts on its own. Every request it makes is listed in the source.

Questions

What is RoLens?
RoLens is a free Roblox trading extension for Google Chrome. It shows live Rolimon's and RoUtility values, RAP, demand and USD estimates on Roblox trades, item pages and inventories, so every offer can be judged without leaving Roblox.
Is RoLens safe to use?
RoLens never asks for your password or session cookie, and it never sends, accepts or counters a trade. The only change it can make to your account is cancelling outbound trades you review and confirm. The complete source is public under the MIT licence, and the version submitted to the Chrome Web Store was independently security reviewed. The privacy policy lists every request it makes.
Which values does it use?
Values, RAP and demand come from Rolimon's, with RoUtility values and USD estimates alongside. Either source can be turned off in the popup.
Where can I install it?
RoLens is free on the Chrome Web Store, for Google Chrome on desktop. The complete source is on GitHub.
