DeBank
Rabby is an open-source non-custodial self-custody wallet built by DeBank, designed for Ethereum and EVM-compatible chains (over 130 networks).

It automatically switches network based on the dApp you interact with. Available as a browser extension, desktop and mobile app; the code is public on GitHub and undergoes periodic audits by SlowMist and Least Authority.

Verdict
Score 4.5/5, very strong profile. In its favour: pre-transaction security checks (simulation + balance changes) that reduce the risk of harmful signatures; open-source and audited; automatic EVM network switching. The trade-off to weigh: eVM-only (no Bitcoin, Solana or other non-EVM chains); seed phrase is the user's responsibility; brand less known to the mainstream public.
On the Sovereignty lens the score is 4.7/5 (outstanding): the strength is fund control (5.0/5), while privacy & anonymity (4.3/5) is the weak link.
