Pros and cons, side by side

Blockstream Green

What works

A cosigning key behind two-factor authentication, so a thief with your unlocked phone still cannot spend
The cosigner cannot trap your coins: a CheckSequenceVerify timelock hands each deposit back to your key alone after about 360 days
An open source recovery tool exists for the case where the 2FA service is permanently switched off
Runs on iOS, Android (Google Play and F-Droid), Windows, macOS and Linux
Pairs natively with Blockstream Jade, so the keys can live on a device instead of the phone
Open source, no documents required, and it can connect to your own node over Tor

What to watch

New 2FA Protected accounts have not been available since May 2025, which is the feature most people came for
Keeping 2FA protection on older coins means redepositing them before each timelock expires
Not bitcoin only, and Liquid balances depend on the Liquid federation rather than on bitcoin's mining
The cosigning server sees a 2FA wallet's transactions, a privacy cost single signature does not have
Three names in circulation (Blockstream Green, the Blockstream app, Multisig Shield) make guides and support articles hard to line up

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
