Is Tomo Wallet safe?

Medium risk

Tomo Wallet embeds static backend authorization credentials for its Bitcoin RPC and BRC20 API requests.

The shipped background bundle includes hardcoded Authorization headers that it uses when posting Bitcoin JSON-RPC calls and BRC20 helper requests. These credentials are static in the extension package rather than secrets you enter, and the requests go to Lorenzo Protocol RPC hosts and xrgb.xyz API hosts.

Shared hosts - 2 hostnames

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.
