Zengo Wallet: How the Seedless MPC Crypto Wallet Works

A traditional wallet derives every key from a 12- or 24-word seed phrase (see public and private keys). Whoever has those words has the funds. Zengo replaces that with multi-party computation (MPC), a cryptographic method where two parties jointly produce a valid signature without either revealing its secret ¹².

1. Wallet creation. The app creates a Personal Share on your phone, and Zengo creates a Remote Share on its servers ¹.
2. Sending. You start a transaction on your phone. The two shares run a joint signing process and output an ordinary blockchain signature ².
3. Control. Zengo says it cannot move your funds alone because it never has your device share ². Equally, you cannot sign without Zengo's server taking part ⁵.

Zengo says its MPC library is open source and audited ¹². The company states that no Zengo wallet has been hacked since 2018 ¹. That is Zengo's own claim; independent databases checked list no Zengo incident ¹², which is the absence of a record rather than proof.

Zengo calls its backup the Recovery Kit. You must set it up before depositing funds ³.

• Email address you used to create the wallet (a secondary email can be added) ²³.
• Recovery file, stored automatically in iCloud Drive (iPhone) or Google Drive (Android), with optional Dropbox or extra cloud copies. The file alone cannot access the wallet ³.
• 3D FaceLock, an encrypted face scan. Since May 23, 2024 it is optional for recovery but required for Zengo Pro security features. A trusted friend's face can be added as a backup ³.

Some zengo.com pages still describe all three as required ("3FA"); the help center describes the current rule ¹³.

The weak points are concrete. Zengo cannot restore a lost recovery file, and editing or moving the file can make the account unrecoverable ³. Losing access to both your email and your cloud account is the main lockout scenario, which is why Zengo recommends adding secondary ones ². Never share the recovery file or email access with anyone claiming to be support.

If Zengo shuts down. Because the server share is needed to sign, Zengo says it runs a "guaranteed access service performed by independent companies" to let users reach their funds if the company stops operating ². The help article does not name those companies, so the arrangement cannot be checked from public documents.

The core wallet is free. Zengo Pro costs $19.99 a month or $89.99 a year as of October 23, 2026 ⁴. It adds ⁴⁵:

• Theft Guard, which requires a face scan for outgoing transactions, so a thief with your unlocked phone cannot send funds.
• Legacy Transfer, which passes assets to a chosen contact after a period of inactivity you set.
• Web3 Firewall warnings for risky transactions and dApp approvals.
• Up to five separate wallets, a Bitcoin privacy mode and Bitcoin "vaults".
• Discounts of up to 50% on buy fees and faster support.

Other costs come from partners and networks. Buying crypto runs through Banxa, MoonPay, Transak and similar providers, each with its own fees ⁶. In-app swaps route through partners such as Changelly and THORChain, and the quote is net of their fees ⁷. Every on-chain transfer also pays the network's fee. Zengo does not publish a single fee table, so compare the final quote before confirming.

Zengo supports Bitcoin, Ethereum, Solana, TRON and other networks, plus NFTs, WalletConnect connections to dApps, ETH staking and a recently added prediction-markets feature that connects to Polymarket ⁸. The main app is mobile; a web login and a separate Zengo Business product for company treasuries also exist ⁸. Support is in-app, which Zengo says runs 24/7 ⁸.

Compared with a seed-phrase app such as Trust Wallet, Zengo removes the single most phished secret in crypto, at the price of relying on a company server. A seed-phrase wallet can be restored in any compatible app without its maker; Zengo cannot, because there is no seed to export ⁵. Which trade-off suits you depends on whether you fear losing a written phrase more than depending on one provider. Our guide to self-custody explains the broader options.
