-[Splits Connect](https://chromewebstore.google.com/detail/splits/ghfacfafnbcgkielpaeifdpoggfeakif) is our browser extension. It lets you use Splits accounts inside third-party apps: the app sees Splits as a wallet, and you sign transactions with your passkey. If your browser doesn't support the extension (e.g. Safari), [WalletConnect](/integrations/walletconnect) works as a fallback. The extension works on all [fully supported networks](/introduction/networks-and-assets).

 # Networks and assets [Supported networks and asset types]
 
-Splits supports some networks fully (every feature) and a longer tail partially (sending and asset recovery only). Owners turn networks on and off per team in [Settings > Networks](https://app.splits.org/settings/team/networks/) (see [Settings](/teams/settings)).
+Splits supports some networks fully (all features available) and a longer tail partially (balances and sending work; accounting history, swaps, bridging, and NFTs may not be available). Owners turn networks on and off per team in [Settings > Networks](https://app.splits.org/settings/team/networks/) (see [Settings](/teams/settings)). Any listed network can be enabled, regardless of tier; **balances are shown for enabled networks only**.
 
 Enabled networks are kept in sync: an account has the same address, signers, threshold, and owner on all of them, because [signer changes are signed once for every active network](/accounts/thresholds#changing-signers-and-thresholds). An account's state is synced to a newly enabled network before the account is used there; disabling a network requires nothing onchain.
 
 Email support to request another network or asset type; most EVM-equivalent networks can be supported, pending our underlying providers.

-## Asset recovery
-
-Tokens received on [partially supported networks](/introduction/networks-and-assets#partially-supported-networks) can be bridged back to a fully supported one from *Asset recovery* in the account's settings, which lists the account's balances on those networks and opens the same swap flow with the source network fixed.

 ## Programmatic access
 
 The [CLI / MCP](/introduction/agents) has no dedicated swap command. Agents can propose swaps as raw calls via `splits transactions create custom` (**Write** scope).
