This review introduces a modern approach to cryptocurrency storage designed for U.S. readers who want clear, practical info. Founded in 2018 in Israel, the company built an app and desktop platform that syncs accounts and simplifies management.
The headline: no traditional seed phrase to manage. Instead, Multi‑Party Computation splits key shares across your device, company servers, and a third party to reduce a single point of failure.
Expect a focused look at core features, protections, fees, availability limits, and whether this wallet fits your use case in 2025. We cover biometric login, encrypted cloud backup, social recovery, a Web3 firewall, and third‑party audits.
Also previewed are supported assets, on‑chain transfers, in‑app purchases, swaps, staking, and the optional card for spending. Note that buying and selling use third‑party services, so fees and limits vary by provider and method.
Read on as the article walks through technology, protections, assets, on‑ramps, setup, Pro features, and direct comparisons to other wallets to give a full picture of control and daily use.
Bottom line: If you want strong security without managing a fragile seed phrase, this approach is compelling for many users in 2025.
The company combines MPC-based protection with a mobile-first app and desktop sync. That makes access fast while keeping private key shares split across device, servers, and a custodian.
Standout features include a Web3 firewall, 3FA (biometric + PIN + email), social recovery, and audited self-custody. These elements make daily use smooth for both beginners and regular traders.
| Aspect | Why it matters | Quick verdict |
|---|---|---|
| Security model | MPC splits key shares to reduce single points of failure | Strong for software-based custody |
| Fees | Partner processing and spreads raise purchase costs | Higher than big exchanges but convenient |
| Usability | Email verification, biometrics, and desktop sync ease onboarding | Great for beginners and mobile-first users |
Trade-offs: Reliance on partner services and some centralized shares may not satisfy maximal decentralization purists. Still, frequent audits and in-app fee previews help users decide before purchases.
This approach replaces a fragile recovery model with distributed cryptography to make custody simpler for everyday people.
Zengo Wallet is a self‑custodial hot wallet that removes the classic seed phrase and uses MPC shares instead. Private key material is split across your device, the company’s servers, and a third‑party custodian so no single party can act alone.
That split reduces the human error risk. Users no longer must write a seed or hide a paper phrase to keep control of funds.
The mobile app offers a clean UI and guided flows for sending, receiving, and storing crypto. A synchronized desktop client adds convenience for larger screens and multitasking.
Multi-party computation lets cryptography do the heavy lifting so no single secret ever exists on its own.
At a simple level, MPC splits a private key into encrypted shares. One share lives on your device, one on company servers, and a third with an independent custodian. Each share by itself is useless, which reduces the chance that a single breach exposes funds.
The three-share structure prevents any single point of failure. If one component fails or is compromised, the other shares keep the account safe. This approach mirrors institutional security practices without forcing complex hardware setups.
When you send crypto, the app and servers perform coordinated math that produces a valid signature. The full private key never appears in one place, so signing is secure and private.
Blockchain confirmations and network fees still govern finality. The MPC model only changes how keys are managed, not how transactions settle.
Recovery is also streamlined: encrypted shares and identity checks help restore access without a written seed phrase. The system aims to balance strong security with everyday usability.
Everyday protections like biometric locks, encrypted backups, and approval filters cut common risks. These controls are designed so users can access funds without juggling fragile phrases or complex hardware.

Three-factor authentication combines a biometric scan (Face ID/Touch ID), a PIN, and email checks. Biometrics secure app entry. Email verification confirms identity for sensitive actions.
Encrypted recovery files stored in iCloud or Google Drive let users restore access if a device is lost. Those files never expose raw keys or a seed phrase.
Trusted contacts can help restore access through a social recovery flow. This replaces risky paper backups and reduces human error when restoring accounts.
Encrypted cloud storage keeps recovery data protected and usable without sacrificing usability or safety.
The built‑in Web3 firewall reviews dApp permissions, warns about risky approvals, and flags suspicious transactions before you sign them.
Independent audits by firms such as Certik and regular assessments add transparency. There are no major reported breaches, which strengthens confidence for US users.
| Protection | What it does | User benefit |
|---|---|---|
| Biometric + PIN + Email | Blocks unauthorized app entry and validates identity | Faster, safer access with layered checks |
| Encrypted cloud backup | Stores recovery file without exposing keys | Simpler device recovery, no seed phrase risk |
| Web3 firewall | Filters dApp calls and shows permission details | Reduces accidental or malicious approvals |
| Third‑party audits | Independent code and cryptography reviews | Improves trust and transparency for users |
Responsive customer support and clear in‑app guidance help users handle edge cases, confirmations, and recovery steps. These features work together to protect funds while keeping daily use straightforward.
Support spans 100+ cryptocurrencies and keeps growing. You can store major coins like Bitcoin and Ethereum, layer‑1 tokens such as Tezos, Solana, BNB, and many ERC‑20s. Popular stablecoins are also available for trading and transfers.
NFTs and dApp access are part of the mix. The app shows and manages Ethereum NFTs and lets users connect to marketplaces through WalletConnect inside a protected environment.
Selective staking is offered for networks like Tezos and Solana, with simple activation and in‑app reward collection. Some sources also show ETH staking options where supported.
Network choice affects fees and settlement times. Bitcoin or Ethereum transfers may cost more and take longer than Solana or Tezos. Pick the chain that fits your transfer speed and fee tolerance.
| Asset type | Examples | User benefit |
|---|---|---|
| Major coins | BTC, ETH | Trusted chains for long‑term holding |
| Layer‑1 tokens | XTZ, SOL, BNB | Low‑fee transfers and staking options |
| ERC‑20 & stablecoins | USDC, DAI, many tokens | Liquidity and trading flexibility |
Buying and moving crypto from the app is simple, but costs and timing depend on the provider you pick.

In-app fiat on-ramps let you purchase assets with credit or debit cards, Apple Pay, Google Pay, PayPal, or bank transfer (SEPA/SWIFT where supported). Integrated providers like MoonPay, Banxa, and Transak power these routes. Fees, limits, and settlement times vary by partner and payment method.
Swaps inside the app generally charge around 0.75%–2% plus possible spreads. Some providers can add ~3% processing and up to ~2% spread on certain trades.
Network congestion affects timing and final quotes. Lower liquidity can widen spreads, so review the estimated costs before confirming any trade.
Staking setup is streamlined. Pick a supported asset, enable staking in the app, and rewards accrue automatically. Supported networks include common stakeable chains; rewards compound per the network rules and appear in your balance.
The Mastercard-linked card converts a chosen asset to fiat in-app, loads the card, and lets you spend at merchants that accept Mastercard. This bridges online and in-store payments with a single funding flow.
Best practices: compare provider fees on the confirmation screen, expect extra verification for large purchases, and test with small amounts before scaling up.
| Action | Typical methods | Cost & timing |
|---|---|---|
| Buy crypto | Card, Apple/Google Pay, PayPal, bank transfer | Cards: faster, pricier. Bank transfer: cheaper, slower |
| Swap | In-app routing via liquidity providers | 0.75%–2% typical; higher with spreads & processing |
| Stake | Enable staking for supported assets | Rewards vary by network; auto-distributed |
| Spend (card) | Convert crypto to fiat, load Mastercard | Instant for card spends after conversion |
Costs matter when you move money into or out of crypto. Fees differ by method, speed, and the partner that processes the transaction. Know what you pay up front to avoid surprises.
Blockchain network fees are unavoidable. Miners or validators collect them and rates change with congestion and asset choice.
Service fees come from partners handling buys, sells, and swaps. These are separate from network charges and vary by provider and payment method.
Bank transfer routes are usually the cheapest but slower. Typical bank transfer totals range from about 1.99% up to ~6.99% depending on region and route.
Credit, debit, and card payments are faster and costlier. Expect typical ranges from roughly 1.99%–5.99% on many providers, with third‑party processors sometimes pushing higher.
Swaps often quote ~0.75%–2% in platform fees. Some partners add processing or spread components that can push costs toward ~3%–5% in some cases.
| Charge type | Typical range | When it applies |
|---|---|---|
| Blockchain network fee | Varies by asset & congestion | Every on‑chain transaction |
| Bank transfer | ~1.99%–6.99% | Slower fiat purchases |
| Card / credit / debit | ~1.99%–5.99% (can be higher) | Fastest purchases |
| Swap fees & spreads | ~0.75%–2% (plus potential processing) | In‑app token conversions |
Bottom line: check the breakdown before you confirm. Compare options on the confirmation screen and, for card buys, consider reading guides like how to buy Bitcoin with credit card to reduce costs and risk.
Global on‑chain access is broad, but fiat rails and partner rules shape who can buy crypto with local money.
The core app lets most users send, receive, and store crypto around the world. On‑chain services work where networks are supported, regardless of local fiat options.
Buying with credit, debit, or bank transfer depends on providers and regional law. Some countries are blocked entirely for fiat purchases, including sanctioned regions such as Iran, Cuba, North Korea, and Syria.
In the United States, fiat purchases are not supported in New York, Hawaii, Rhode Island, and the U.S. Virgin Islands. Several other states may allow only certain assets or impose purchase limits.
Check in the app by ZIP code to confirm which payment methods and coins are available where you live.
| Item | Impact | Action |
|---|---|---|
| Regional bans | No fiat purchases | Use on‑chain only or a compliant broker |
| State limits | Partial asset availability | Check ZIP eligibility in‑app |
| KYC level | Purchase ceiling | Complete verification for higher limits |
Support teams can explain eligibility messages and help with account verification or provider‑specific issues. Always review in‑app disclosures since partner services and limits change over time.
Getting started is fast: install the app on iOS or Android (desktop is optional), verify your email, choose a PIN, and enable biometrics for quick, secure sign-in.
After installing, the app sends an email to confirm your account and unlock features. Complete that step before creating a PIN.
Enable Face ID or Touch ID to speed daily access while keeping the app protected by multi-factor checks.
Create an encrypted cloud backup (iCloud or Google Drive) so you can restore storage and settings if the device is lost or replaced. This avoids a written seed while keeping recovery safe.
Set up social recovery by designating trusted contacts who can approve regain-access requests. Their confirmations help restore your account when needed.
Keys never appear in raw form; the app coordinates secure signing under your biometric and PIN protections. If anything goes wrong, support can help with onboarding, recovery, or transaction troubleshooting.
For active traders and estate planners, the Pro tier adds features that tighten control and simplify advanced needs. This paid upgrade targets users who want more granular security, faster help, and cost savings on repeated buys.

Enhanced firewall gives granular warnings and policy controls for dApp connections. It reduces risky approvals and flags malicious contract interactions before you sign.
Theft Protection adds extra confirmation steps for high‑risk actions. Those frictions help stop remote or automated attempts to move funds from your account.
Legacy Transfer lets you name a beneficiary who can claim assets after set inactivity conditions. This aids inheritance planning without exposing secrets.
Private mode for BTC improves on‑chain privacy, and time‑locked vaults add delayed access for large holdings. Together, they raise protection for long‑term storage and estate scenarios.
Pro subscribers get priority support, faster responses, and discounted on‑ramp fees that can offset the subscription for frequent buyers. Pricing is shown in the app during signup so you can compare value.
Decide by activity: choose Pro if you trade often, hold sizable balances, or need inheritance tools. The app clearly tags Pro‑only options so you can trial benefits before committing.
| Benefit | Why it matters | User result |
|---|---|---|
| Firewall upgrades | Stricter dApp controls | Fewer malicious approvals |
| Theft Protection | Extra confirmations | Stops unauthorized moves |
| Legacy & vaults | Inheritance & time locks | Safer long‑term storage |
Not all crypto storage tools work the same; their design affects security and convenience.
Keyless MPC removes a single written recovery phrase by splitting secret shares across components. That reduces the common user error of losing or exposing a seed phrase while keeping user control intact.
By contrast, MetaMask and Trust Wallet rely on a seed phrase that you must store safely. Ledger uses a hardware device and a seed backup on paper, offering strong offline guarantees but requiring physical care.
Ease of use matters for new users. Guided flows and a built‑in firewall simplify dApp approvals and limit risky signatures. This helps less technical users avoid costly mistakes.
MetaMask shines on EVM networks and dApp flexibility, while Trust Wallet offers open‑source mobile simplicity. Ledger is best for users who want offline signing and tight physical security.
| Feature | Strength | Trade‑off |
|---|---|---|
| Seed phrase wallets | Wide compatibility (dApps, plugins) | User must secure a recovery phrase |
| Hardware device | Strong offline security | Requires physical device & backup |
| MPC / key split | Reduced seed management, social recovery | Relies on coordinated services during signing |
How to choose: match the model to your risk tolerance. Pick hardware for cold storage, seed wallets for dApp flexibility, or an MPC approach if you want convenience without managing a paper seed.

Choosing the right custody model depends on how you balance convenience, control, and long-term access.
Best fit: beginners, mobile-first users, and seed-averse holders who want self-custody without written recovery phrases.

With over a million active users by mid‑2025, this option appeals to people who value quick access, simple navigation, and guided setup flows. Built-in protections like biometrics, encrypted cloud backups, and social recovery make regaining access easier for non-technical users.
Casual traders and NFT collectors benefit from integrated swaps, staking for select assets, and dApp connections that reduce tool juggling. The Web3 firewall warns about risky approvals, which helps users avoid costly mistakes when interacting with contracts.
Everyday utility: the linked card lets users convert crypto to fiat and spend at merchants, making funds practical for daily use. That ease-of-use suits mobile-first lifestyles.
Heavy traders or those demanding maximal decentralization may prefer hardware devices or open-source stacks with manual seed management. If you trade large volumes or need offline signing, a hardware solution remains the safer choice.
Final note: weigh convenience against your security needs. For many U.S. users, the blend of usability, features, and support here offers a balanced route to holding and using crypto.
strong, The service pairs modern cryptography with user-focused features to make holding and spending crypto simpler.
Why it stands out: the MPC model removes seed phrase risk while keeping self‑custodial control and practical recovery options like social recovery and encrypted backups.
Security layers — biometrics, 3FA, and a Web3 firewall — work together to protect on‑chain actions and dApp interactions. Regular audits and no major reported breaches support its safety claims.
Functionality is broad: 100+ supported assets, in‑app purchases and swaps, staking, and a Mastercard‑linked payment card for everyday spendability. Fees vary by partner and bank or card method, and U.S. purchases face state limits.
Verdict: for many beginners and mobile‑first users, this review finds a balanced model that makes self‑custody approachable. Do final due diligence, check in‑app limits, and start with small purchases to verify timing and costs on your preferred network.
The keyless model uses multi-party computation (MPC) to split cryptographic control across multiple parties instead of relying on a single seed phrase. This removes the need to write down a recovery phrase while still keeping private access to cryptocurrency protected on your device and by encrypted backups.
MPC splits signing into separate shares held on your device, a server, and a custodial or recovery module. When you initiate a transfer, the shares jointly compute a valid signature without ever reconstructing a single private key, reducing exposure to theft and improving security for on‑chain transactions.
Yes. The platform supports cloud backup and social recovery options that use trusted contacts and verified email as recovery channels. You can regain access by reconstructing key shares through those verified methods, avoiding reliance on a written seed phrase.
The service supports major networks including Bitcoin, Ethereum, Solana, Tezos, BNB Smart Chain, and many ERC‑20 tokens. It also supports NFTs on compatible chains and stablecoins for trading and payments.
In‑app fiat on‑ramps connect to providers that accept card payments, Apple Pay, Google Pay, and bank transfer. The exact availability and fees depend on your country and chosen payment method. Purchases settle to your account after provider processing and network confirmation.
You’ll pay on‑chain network fees for miners or validators plus any service fees for swaps or fiat conversion. Network fees vary by blockchain load; swap spreads and provider processing fees vary by payment method and region.
A Pro tier adds features such as an enhanced Web3 firewall, theft protection, priority customer support, legacy transfer tools, private‑mode options for specific chains, and reduced on‑ramp fees for frequent traders.
MPC offers strong protection without a seed phrase, and it’s more convenient for mobile users. Hardware wallets keep a single private key offline and are still considered one of the strongest self‑custody options for high‑value storage. The choice depends on your threat model and preference for convenience versus absolute offline keys.
The app provides global access for crypto management, but fiat on‑ramps and buying services vary by country and U.S. state due to regulatory and KYC requirements. Some states may have partial exclusions for card or bank transfers; check the app’s supported country list before attempting fiat transactions.
Support teams assist with KYC verification, recovery procedures, and transaction issues. Premium users often receive priority response times. For security, support will verify identity through email, biometric data, and other account checks before assisting with sensitive actions.
Yes. The platform supports dApp connections and in‑app swaps for DeFi use. The app includes features to manage approvals, monitor liquidity, and interact with smart contracts while aiming to protect private keys during on‑chain interactions.
The security stack includes biometric login, PIN, encrypted backups, Web3 firewall protections, and third‑party audits. Social recovery and email verification add layers that make unauthorized account takeovers more difficult.
Swaps route through liquidity providers and incur swap spreads plus on‑chain fees. Staking lets you earn rewards for supported assets, with platform fees or validator commissions deducted per protocol rules. Costs depend on the chosen asset and network.
For fiat services and certain on‑ramp features, KYC is required by providers and regulators. The keyless custody model itself focuses on cryptographic security, while identity checks are part of payment and compliance flows.
You can transfer assets on‑chain by sending from your external wallet to your new account address. For tokens and NFTs, ensure you use the correct network and include sufficient native gas for the transaction to complete.
MPC is designed so a single compromised share cannot authorize transactions. Continuous auditing, encryption, and the ability to rotate or revoke shares help mitigate risks. Users should enable available protections like biometrics and social recovery to further reduce exposure.
