Our part
We built BW3 with its wallet, VPN and ad blocking inside the browser.

The client and the problem

LayerAI wanted a browser that could be the front door to its Web3 ecosystem, where people hold assets, sign transactions and browse privately without installing anything else.

What we built

We built BW3 as a Chromium/Brave-based browser with a wallet, a VPN and custom ad-block integration inside the browser itself. Signing a transaction, turning on the VPN or blocking ads needed no extension and no second app.

  • A built-in wallet that needs no extension
  • A native VPN
  • Custom ad-block integration

Why it was hard

A VPN and a wallet inside the browser ship on the browser’s release schedule, not an extension store’s. Every Chromium and Brave update has to carry that code forward and be tested again before release, which is far easier when the custom code sits in small, separate patches.
