When using the default settings, Trezor Suite connects to SatoshiLabs’ open-source backend Blockbook, which also serves a blockchain explorer.
Backend settings can be changed via Settings > Crypto, and then clicking on the settings gear icon for a particular coin, which is revealed on hover; e.g. for Bitcoin:
Clicking this reveals the Backends window:
On discovery, Trezor Suite first shuffles the default addresses randomly and takes them one by one until a successful connection is made. This is expected behavior that prevents overflow of one specific connection.
If you have enabled Tor
and are running a node over the onion router, your custom backend connection will automatically attempt to connect to .onion
Custom backends can be setup using the drop-down menu at the top of the Backends window:
The backend address hierarchy in Trezor Suite is implemented in such a way that if you have set up multiple custom backends, Trezor Suite will:
- Immediately try to connect to the first local custom address listed.
- If unsuccessful, Suite will cycle through any remaining localhost addresses.
- If localhost addresses are unsuccessful, Trezor Suite will then search for Tor addresses.
