Zengo:
no seed phrase at all, and a real question over exactly how your key is split.
We tore apart Zengo, the first consumer wallet built on institutional-grade MPC cryptography, across the same seven weighted categories as this series; from a genuinely pioneering "keyless" architecture that eliminates the classic seed phrase entirely, distinctive anti-spoofing biometric recovery, and regular published security audits, to a real, mobile-only platform with no desktop presence, narrower NFT and token network coverage than the broad headline coin count suggests, and a real, unresolved discrepancy across sources over whether your key is split two ways or three; and landed on a score the marketing page won't show you.
Our take, up front: Zengo, founded in 2018 and headquartered in Tel Aviv, was genuinely the first consumer-facing wallet to use Multi-Party Computation (MPC), a threshold cryptography approach previously available only at the institutional level through firms like Coinbase and Fireblocks. The well-established, real core design splits signing capability into two independent secret shares, one on your device, one on Zengo's server, and both are required to approve any transaction; neither party ever holds the complete key, and there's no seed phrase to lose, photograph, or hand to a scammer. Real, distinctive recovery replaces the written phrase entirely with a three-factor process combining biometric verification (3D FaceLock, independently timed at under 20 seconds and reported to reject high-resolution photo and video spoofs), your device, and an encrypted cloud backup. We found no reported hacks specific to Zengo in our research, and the company publishes regular third-party security audits. What we can't set aside: Zengo is mobile-only, with no desktop application or browser extension found anywhere in our research, a real gap relative to the last two wallets we reviewed in this series. Real, more specific limitation beneath the broad 1,000-plus asset headline: NFT and token support is confirmed only on Ethereum and Polygon specifically. And here's a real, unresolved discrepancy worth stating plainly: one detailed source describes your key split three ways, across your phone, Zengo's server, and a third-party custodian, while the more consistently-described architecture across other sources is a two-share split between your device and Zengo alone. We're presenting that honestly rather than picking a side. We weighted all of it below.

The well-established core design splits signing capability into two independent secret shares, one on your device, one on Zengo's server, and both are required to approve any transaction; neither party ever holds the complete key, and there's no seed phrase to lose or leak. Real, distinctive three-factor recovery replaces the written phrase entirely, combining biometric verification (3D FaceLock, independently timed at under 20 seconds and reported to reject high-resolution photo and video spoofs), your device, and an encrypted cloud backup. Real, notable transparency nuance: the codebase is partially open-source, with some components remaining closed, a real middle ground between the fully closed code we found reviewing Exodus and the fully open code we found reviewing MetaMask. Regular, published third-party security audits and no reported hacks found in our research are real positives. Real, unresolved discrepancy worth precision: one detailed source describes a three-way key split across phone, server, and a third-party custodian, which we couldn't reconcile with the more consistently-described two-share model found across most other sources.
Pros
- Genuinely pioneering MPC architecture eliminates the classic seed-phrase failure mode
- Distinctive, anti-spoofing biometric recovery with no written phrase to lose or leak
- Regular published security audits; no reported hacks found in our research
Cons
- Real, unresolved discrepancy across sources on whether the key splits two ways or three

- Zengo's own infrastructure remains a required party for signing and recovery
Real, broad headline coverage: over 1,000 supported assets, including Bitcoin, Ethereum, BNB, Dogecoin, Tezos, and a wide range of stablecoins. Real, more specific limitation: NFT and token support is confirmed only on the Ethereum and Polygon networks specifically, meaningfully narrower than the broad top-line asset count might suggest.
Pros
- Over 1,000 supported assets, a genuinely broad headline count
- Broad stablecoin coverage
Cons
- NFT and token support confirmed only on Ethereum and Polygon specifically
Real, consistently and independently praised interface, described as intuitive with clear transaction feedback and built-in educational content aimed at easing onboarding for newcomers. The 3D FaceLock biometric login is a real, genuinely fast and distinctive verification step. A real, built-in Web3 firewall flags risky transactions and signing requests before you approve them.
Pros
- Consistently praised, intuitive interface with clear transaction feedback
- Real, fast 3D FaceLock biometric login
- Built-in Web3 firewall flags risky transactions before signing
Cons
- None significant found in our research

A genuinely different answer to the seed-phrase problem, not a free lunch.
Zengo solves a real, specific failure mode better than either of the first two wallets we reviewed in this series: there's no written phrase to lose, photograph, or hand to a scammer, full stop. That's genuine, well-established cryptographic engineering, not marketing gloss. The honest trade-off is that removing the seed phrase doesn't remove trust, it relocates it: Zengo's own infrastructure is now a required party for both signing and recovery, in a way that a fully self-sovereign seed-phrase wallet, paired with a hardware device, isn't. Add a mobile-only platform and NFT support that's narrower than the headline coin count implies, and this reads as a genuinely strong option for the specific failure mode it targets, not a strictly superior wallet to everything that came before it.
The scorecard above is deliberately general. Whether Zengo is right for you depends heavily on which of these you already are.
The mobile-first holder who has specifically worried about losing a written seed phrase
The MPC architecture genuinely eliminates that exact failure mode, replacing it with biometric and device-based recovery.
The newcomer who wants a genuinely beginner-friendly on-ramp with strong built-in safeguards
The intuitive interface, fast biometric login, and built-in Web3 firewall are real, well-regarded strengths for first-time self-custody.
The holder whose main activity is Ethereum and Polygon-based assets and NFTs
Asset and NFT coverage is genuinely strong within this specific scope, less so outside it.
Desktop-primary users, or anyone who wants zero reliance on any company's infrastructure
There's no desktop app or browser extension, and Zengo's own servers remain a required party for both signing and recovery.
The scorecard covers the headline judgment calls. These four tables cover the specifics we didn't want to bury in prose; the 2-share vs. 3-share key-split discrepancy, how MPC differs from a traditional seed phrase, Zengo vs. Exodus vs. MetaMask across the three custody models this series has now covered, and how it compares against the general hot-wallet baseline.
The key-split discrepancy, across sources
| Description | Source pattern |
|---|---|
| Two-share split: device + Zengo server | The more consistently-described architecture across most detailed sources |
| Three-share split: phone + server + third-party custodian | One detailed source; not corroborated elsewhere in our research |
The two-share model matches Zengo's well-established, publicly-documented threshold cryptography design; the three-share description may reflect a conflation with the separate three-factor recovery process. We couldn't fully resolve this from available reporting.
How MPC differs from a traditional seed phrase
| Seed phrase wallet (Exodus, MetaMask) | Zengo (MPC) | |
|---|---|---|
| Backup format | 12-24 written words | Biometric + device + encrypted cloud backup |
| Single point of failure | Yes, the written phrase | No; two independent shares required to sign |
| Full key ever exists in one place? | Yes, when the phrase is written or entered | No, per the two-share design |
| Company involvement required to sign? | No | Yes, Zengo's server is one of the required parties |
This is a real, genuine trade-off, not a strict upgrade: MPC removes the seed-phrase failure mode but introduces a dependency on Zengo's own infrastructure that a seed-phrase wallet doesn't have.
Three custody models, compared
| Exodus | MetaMask | Zengo | |
|---|---|---|---|
| Custody model | Seed phrase | Seed phrase | MPC, keyless |
| Code transparency | Closed-source | Open-source | Partially open-source |
| Platforms | Desktop, mobile, browser | Browser, mobile | Mobile only |
| Cross-device sync | Automatic | Manual | N/A (mobile-only) |
Each wallet in this series so far makes a genuinely different trade-off; there's no universally "best" model, only the one that best fits your specific priorities.
How it compares to a general hot-wallet baseline
| Factor | Zengo | General hot-wallet baseline |
|---|---|---|
| Custody model | Non-custodial, MPC-based | Varies; most competitors use a seed phrase |
| Seed phrase risk | Eliminated entirely | Present in most competitors |
| Platform reach | Mobile-only | Varies; several competitors cover desktop and browser too |
Zengo's MPC model is a genuine outlier in this series so far, trading platform breadth for a fundamentally different, real answer to the seed-phrase problem.
We don't just want to hand you our number; we want to show you how it sits next to what other review desks and comparison sites have published. Coverage here is generally enthusiastic about the genuine novelty of the MPC approach.
Our score lands meaningfully below the aggregated industry average; most sources emphasize the genuine innovation of eliminating the seed phrase without weighting the mobile-only platform limitation, the narrower NFT/token network coverage, or the real key-split discrepancy as heavily as we do.

Scores compiled by our editorial team from publicly available reviews as of August 2026. "Editorial estimate" means the outlet didn't publish a single numeric score, so we converted their published verdict and sentiment into a comparable 100-point figure. Verify current figures directly with each source before citing them elsewhere.
Correct, there's no traditional written seed phrase at all. Instead, your signing capability is split into independent secret shares using Multi-Party Computation (MPC), and recovery relies on biometric verification, your device, and an encrypted cloud backup.
Most detailed sources consistently describe a two-share split between your device and Zengo's server. One source describes three shares across your phone, the server, and a third-party custodian, which we couldn't corroborate elsewhere; this may reflect a conflation with the separate three-factor recovery process.
Zengo describes itself as non-custodial because it never holds a complete key capable of moving your funds unilaterally; both shares are required to sign. That said, this is a genuinely different trust model than a wallet where you alone hold the complete key offline.
No, Zengo is mobile-only. We found no desktop application or browser extension anywhere in our research, a real gap relative to Exodus and MetaMask.
Partially. Some components are open-source, while others remain closed, a real middle ground between the fully closed code we found reviewing Exodus and the fully open code we found reviewing MetaMask.
The core wallet is free. An optional Pro subscription unlocks additional security upgrades, a different monetization model than the swap-fee-based approach used by Exodus and MetaMask.
A biometric verification technology powered by FaceTec, independently timed at under 20 seconds and reported to reject high-resolution photo and video spoofing attempts, used as one factor in Zengo's recovery process.
We found no reported hacks specific to Zengo in our research, and the company publishes regular third-party security audits.
