Bitcoin Core4.7Bitcoin-only

The reference implementation, and the only wallet here that checks the rules itself instead of trusting somebody else's server.

Zengo3.4

The wallet with no seed phrase: two MPC shares replace the private key, which removes one risk and adds a dependency.

Pros and cons, side by side

Bitcoin Core

What works

  • Validates every rule for itself, so your balance does not depend on someone else's server being honest
  • Bitcoin only, with the keys in a wallet file on your own machine and no account anywhere
  • Every vulnerability the project has fixed is published, dated and classified on its own advisory page
  • Free and open source, maintained by a large contributor base rather than by a company
  • Doubles as the private backend for friendlier wallets such as Sparrow
  • Pruned mode still validates every block while keeping a far smaller amount of data on disk

What to watch

  • The first sync downloads and verifies the whole chain, which costs hours and a lot of disk space
  • Desktop or server only: there is no phone app
  • A plain wallet interface with no fiat on-ramp, no price display and no hand holding
  • Running an old version leaves you exposed to bugs the advisory page has already described

Zengo

What works

  • No seed phrase exists, so there is nothing to write down, photograph, or be tricked into typing
  • Two independently created MPC shares, one on your phone and one on Zengo's server, that are never combined
  • Three factor recovery, with a documented option to register a backup for each of the three
  • Zengo says its MPC cryptography is open source, audited and peer reviewed
  • Support is available 24/7 from inside the app, which is rare in self-custody

What to watch

  • Signing requires Zengo's server, so the wallet depends on the company staying reachable in a way a seed phrase does not
  • The wallet app itself is closed source; only the cryptography underneath it is published
  • Recovery runs through your email, your cloud account and a face scan, which is three dependencies instead of one piece of paper
  • Never hacked and 2+ million wallets are Zengo's own claims on Zengo's own homepage, with no independent confirmation
  • Mobile only, with no desktop app and no hardware signing
