Guarda wallet is a non-custodial, multi-chain wallet that has run since 2017 and comes as a browser-based web wallet, desktop apps, mobile apps and a Chrome extension. Its main distinguishing feature is also its main risk: instead of relying only on a seed phrase, Guarda’s web and desktop versions store your keys in an encrypted backup file unlocked by a password. This review is based on Guarda’s help centre, company disclosures and independent reporting as of October 2026, without personal use of the app, and starts with the web-wallet risks before covering coverage and fees.
Key takeaways
- Guarda says it does not hold your keys, passwords or backups. If you lose both the backup file and its password, Guarda support states it cannot restore the wallet.
- The web wallet runs in a browser tab, which makes look-alike websites and malicious extensions the main threat. Always type the address yourself.
- Guarda claims support for 70+ blockchains and over a million tokens (company figures, October 2026). Swaps and card purchases are routed through partners: ChangeNOW, Guardarian and Simplex.
- The main multi-coin apps are proprietary; only some single-coin wallets have been published on GitHub, so the full code cannot be audited independently.
- There is no secure element. Ledger lists Guarda as a compatible third-party wallet for keeping keys on a hardware device.
Guarda’s apps: web, desktop, mobile and extension
Guarda is unusual in offering a full wallet inside a normal web page, alongside downloadable versions. According to the company’s website, the wallet service is provided by GUARDACO LDA, registered in Lisbon, Portugal, and GUARDIUM LTD, registered in Road Town, Tortola, British Virgin Islands. Earlier reporting placed Guarda’s legal base in Estonia before the move to Portugal.
| Version | Where keys live | Specific risk to watch |
|---|---|---|
| Web wallet (browser tab) | Encrypted backup cached in your browser; unlocked with your password | Clone websites; malicious or compromised browser extensions; clearing the cache logs you out |
| Chrome extension | Encrypted inside the browser profile | Fake listings in extension stores; other extensions with broad permissions |
| Desktop (macOS, Windows, Linux) | Encrypted on your computer | Malware on the computer; fake installers from search ads |
| Mobile (iOS, Android) | Encrypted on the phone, optionally behind biometrics | Copycat apps in app stores; phone theft without a screen lock |
The web version is convenient for quick access from any computer, but it is the version most exposed to the browser environment. A wallet that can be opened by visiting a URL can also be imitated by any site that copies its look.
Guarda wallet backup file vs seed phrase
Guarda’s help centre describes the backup as “an encrypted TXT file containing the recovery information” for your wallets. Your password decrypts it, and you need both to restore. Guarda states that none of this data is stored on its servers. Because of that design, Guarda backups behave differently from the 12- or 24-word phrases most wallets use (our seed phrase explainer covers that standard).
| Question | Guarda backup file + password | Recovery phrase / private keys |
|---|---|---|
| What restores it? | The file and the matching password, inside Guarda | The phrase or key, in Guarda or another compatible wallet |
| Does it go out of date? | Yes. Guarda says the file changes when you add, import or remove a wallet, or change your password | A phrase covers every account derived from it; separately imported keys need their own backup |
| Where does it sit by default? | In the web version, cached in the browser until you download it | Wherever you wrote it down |
| If someone steals it? | They still need the password, but Guarda says password attempts are not limited, so a weak password can be guessed offline | Immediate full access |
| If you lose the password? | Guarda cannot recover it; fallback is any private keys you saved separately | No password needed |
Practical rules for Guarda backups
- Download a fresh backup after every change to your wallet list and delete superseded copies you do not need.
- Use a long, unique password stored in a password manager or written offline; the backup is only as strong as that password.
- Keep the backup file off email and shared cloud folders.
- Export and store private keys for wallets holding meaningful balances, so you are not dependent on Guarda’s software to recover them.
Is Guarda wallet safe? The web wallet’s phishing problem
Guarda has not, as far as public reporting through October 2026 shows, suffered a platform-wide breach comparable to the June 2023 Atomic Wallet theft. The documented risk is more ordinary and more common: users entering a backup and password into a copy of the web wallet. The pattern is consistent across multi-chain wallets. A search ad or social post points to a near-identical domain; the page asks you to “restore from Guarda backup”; the file and password are sent to the attacker. Our guide to fake crypto websites explains how these clones are built and how to spot them.
Specific defences for Guarda users:
- Guarda’s main domain is guarda.com. Guarda’s own help articles also send users to its web app on guarda.co. Type these addresses yourself and bookmark them; do not reach them through ads, DMs or “support” links.
- Install desktop apps only from the downloads page on the official site, and mobile apps from the App Store or Google Play listings it links to.
- Use a separate browser profile with no other extensions for the web wallet. Extensions that can “read and change all your data on websites” can see what you type.
- Guarda staff will never ask for your backup file, password or private keys. Anyone who does is a scammer.
For larger balances, the gap that no software fix closes is the lack of a secure element: keys are decrypted on an internet-connected device. Ledger’s website lists Guarda as a compatible third-party wallet, which lets the private keys stay on the Ledger device while Guarda shows balances and builds transactions. Check which chains the integration supports before relying on it. The wallets and security hub covers hardware pairing in more depth.
Guarda supported coins, chains and swaps (dated)
As of October 2026, Guarda’s homepage claims support for more than 70 blockchains and over one million tokens, purchases of 300+ assets and staking on 14 networks. These are company figures; check that the specific network and token standard you need is listed before sending funds, especially for less common chains where sending to the wrong network can mean permanent loss.
Guarda fees
Guarda says there are no platform fees for sending or using the app; you pay the blockchain’s network fee. The costs sit in the partner services:
| Service | Provider named by Guarda | How you pay |
|---|---|---|
| Send / receive | The blockchain itself | Network fee only, per Guarda |
| Crypto-to-crypto swap | ChangeNOW | Partner rate and fee built into the quote |
| Buy with card / bank | Guardarian, Simplex | Partner fees and spread, plus the partner’s own KYC |
| Staking | Network validators | Variable rewards minus validator commission |
Guarda does not publish one flat swap or purchase percentage, so compare the amount you will receive on the quote screen with an exchange rate elsewhere before confirming. Swap partners can also delay or hold transactions for compliance reviews, which is a custodial step outside Guarda’s control.
Custodial extras: card and buy services
Guarda is self-custody only while coins sit in the wallet. Once you use a buy or swap partner, that partner briefly controls the funds and applies its own identity checks. Guarda launched a prepaid Visa card for EU customers in 2022, funded by converting crypto to euros; that is a custodial product run with card-issuing partners. Guarda’s current homepage does not feature the card, and this review could not confirm whether new card applications are open as of October 2026, so check inside the app or with Guarda support before planning around it.
If you mainly want a phone wallet and do not need a browser version, our mobile wallet comparison sets out the alternatives, and the Trust Wallet review covers a rival multi-chain app with a different recovery design.
Open-source claims and certifications
Guarda’s multi-currency apps are proprietary. Third-party reviewers, including NerdWallet, list closed-source code as a drawback, and WalletScrutiny reported that Guarda’s public Android repository builds single-coin wallets but not the multi-coin app published in the Play Store, so it could not verify that the store build matches public code. The Monero project likewise added Guarda to its website’s downloads list with a closed-source warning. In practice, you are trusting Guarda’s development and release process rather than code anyone can rebuild.
Guarda’s homepage displays EU and INATBA association logos but, when checked in October 2026, did not describe a current SOC 2 report or ISO 27001 certificate. If a certification matters to you, ask for the report or certificate and its scope; an audit of a company’s internal controls is not the same as an audit of wallet code.
Who Guarda suits, based on its documentation: people who want one interface for many networks, including a browser version, and who are disciplined about backups. Who it suits less: anyone who wants verifiable open-source code, or anyone likely to store a backup file casually.
FAQ
Is Guarda wallet safe to use?
Guarda is non-custodial and no platform-wide breach has been publicly reported through October 2026, but the apps are mostly closed source and have no secure element. Most losses come from phishing copies of the web wallet and weak backup passwords. Use the official domain, a strong password and a hardware wallet for larger sums.
What is a Guarda backup file?
It is an encrypted text file holding the recovery information for the wallets in your Guarda account. You need the file and its password to restore. Guarda stores neither, and a new backup is needed whenever you add, import or remove a wallet or change the password.
Can I use the Guarda web wallet without downloading anything?
Yes. The web version runs in a browser and keeps an encrypted backup in the browser cache. Clearing the cache logs you out, after which you restore with the downloaded backup file and password. Download the backup immediately after creating or changing the wallet.
How many coins does Guarda support?
As of October 2026, Guarda claims support for more than 70 blockchains and over a million tokens, with 300+ assets available to buy through partners. These are company claims; confirm the exact network and token standard in the app before depositing.
