Silent Mode's own components that ship inside Theseus and appear under Settings › Plug-ins: the wallet and the system-wide resolver. Community-made add-ons live on the separate Extensions page.
Multi-chain wallet derived from your Theseus vault (BCH, BTC, TRX, ETH, SOL, SC, DGB) with a dApp bridge for the pages you visit. Bundled with every Theseus build and updated over a signed channel between releases; the panel's own Stage → Restart flow applies an update without reinstalling Theseus.
theseus.x/extensions/aegis/updates.json…—Makes BCDN names resolve for every program on the machine, not only Theseus: a local DNS resolver plus gateway, installed by Theseus's setup by default (opt-out) and switchable from Settings › Plug-ins. The same resolver ships standalone for Windows and as Ariadne for Android.
——Plug-ins are first-party: Silent Mode builds them, signs them with the operator key, and Theseus treats them as part of itself (own Settings section, own update flow). Extensions are everyone else's: published by any BCDN name holder, signed with that name's wallet, listed on theseus.x/extensions and installed from Settings › Extensions. Both are verified on your device before a byte runs.
