The official site zengo.com returns a 403 error to automated checks, so the chain list, the technical details of the MPC model and the exact Zengo Pro price are reconstructed from third-party sources (industry press, reviews, eToro announcement) rather than the official product page. The Zengo Pro price in particular has changed over time (reported between ~$9.99 and ~$19.99/month depending on source and period) and should be re-verified directly in the app.
For this reason this service does not appear in our rankings, comparator or comparison pages: it will once its terms can be verified against a dated official document.
Zengo
Zengo (KZen Networks)
Zengo is a non-custodial mobile wallet (iOS and Android, with web access) built around MPC (Multi-Party Computation) cryptography: there is no seed phrase to write down and safeguard. Instead of the classic single secret, signing capability is split into several independent "shares" — typically one on the user's phone, one on Zengo's servers and one held by a third party for recovery — that cooperate at signing time without ever reconstructing a single private key. This removes the single point of failure of a seed (theft, a photo, a lost backup) but shifts part of the trust onto Zengo's infrastructure, which remains closed-source software: that is the key trade-off to understand before using it. Recovery happens through an encrypted backup and biometric face verification, not through 12 or 24 words. Zengo is multi-chain (Bitcoin, Ethereum and other networks) and offers in-app buy, sell and swap. There is a paid tier, Zengo Pro, with advanced features such as time-locked Bitcoin vaults, private transactions and inheritance tools. Corporate note: on 15 April 2026 eToro announced the acquisition of Zengo for roughly $70 million to strengthen the platform's self-custody offering.

Strengths
- No seed phrase to safeguard thanks to the keyless MPC model; recovery via encrypted backup and face biometrics; multi-chain with built-in buy/sell/swap; strong security track record.
- Self-custody: funds stay in your wallet — the platform cannot touch them.
- No KYC: usable without identity verification.
Weaknesses
- Closed-source software: part of the trust stays on Zengo's infrastructure (one share sits on its servers); no hardware wallet integration; advanced features require the Zengo Pro subscription; the eToro acquisition is worth watching for possible product changes.
- Closed source: no way to verify what it does with wallet and data.
Verdict
Score 4.1/5, solid profile. In its favour: no seed phrase to safeguard thanks to the keyless MPC model; recovery via encrypted backup and face biometrics; multi-chain with built-in buy/sell/swap; strong security track record. The trade-off to weigh: closed-source software: part of the trust stays on Zengo's infrastructure (one share sits on its servers); no hardware wallet integration; advanced features require the Zengo Pro subscription; the eToro acquisition is worth watching for possible product changes.
On the Sovereignty lens the score is 3.1/5 (solid): the strength is fund control (5.0/5), while trustless / auditability (0.0/5) is the weak link.

FAQ
Does Zengo really work without a seed phrase?
Yes. Zengo uses MPC cryptography: signing capability is split into several independent shares (one on your phone, one on Zengo's servers, one held by a third-party custodian for recovery) that cooperate without ever reconstructing a single private key. So there is no 12- or 24-word seed to write down: recovery happens through an encrypted backup and biometric face verification.
Is Zengo custodial?
No, Zengo is non-custodial: no single share can move funds and Zengo cannot spend on your behalf. But understand the trade-off: one of the shares lives on Zengo's servers and the software is closed-source, so part of the trust rests on the company's infrastructure, unlike an open-source self-custody wallet with the seed on your own device.
How much does Zengo cost?
The base app is free. There is a paid tier, Zengo Pro, adding features such as time-locked Bitcoin vaults, private transactions, inheritance tools and reduced purchase fees. The price has varied over time (reported between roughly $9.99 and $19.99 per month depending on source and period): verify it directly in the app, since the official site cannot be checked automatically.
