What actually differs between the app and the web version

The split, and the reason behind it

The underlying principle: a phone is optimised for capture and for glancing; a desktop is optimised for verification before commitment. Match the task to the strength.

Verification: the app, clearly

If the face check is failing on a laptop, this is the highest-value change you can make. A recent phone's front camera substantially outperforms a typical laptop webcam in resolution, low-light behaviour and focus, and the app's capture flow gives live framing feedback rather than a single shot in the dark.

The document capture is the same story. Holding a card at a controlled distance and angle is easy with a phone in your hand and awkward in front of a fixed laptop lid. Full walkthrough in when verification keeps failing.

Orders and withdrawals: the web, clearly

This is the half people get wrong, because the app is right there.

The specific hazard is that a mobile order form shows you one field at a time. You enter a quantity, scroll, enter a price, scroll, confirm — and the confirmation screen is a summary you have already stopped reading. On a desktop the order book, the form and the resulting total are on screen simultaneously, so an order that is ten times too large looks wrong immediately rather than after it fills.

Withdrawals are worse, because there are three fields that all have to be right at once: the address, the network and the amount. On a phone you cannot see all three plus the confirmation without scrolling, and scrolling is where verification quietly turns into scrolling past. Given what a wrong network selection costs — see which chain to withdraw on — this is not a preference, it is a control.

Our position: for withdrawals, use the web where you have the choice, read the summary out loud, and use a test transfer for anything new. If you must do it on a phone, do it sitting down, not walking.

The one thing only the app does

Push notifications. This is a genuine capability gap, not a convenience.

The security value is specific: a withdrawal-address addition, a new device sign-in or a large withdrawal generates an alert that reaches you within seconds. That alert is what turns the delay built into a withdrawal whitelist into something you can actually act on. A whitelist delay you sleep through has done nothing.

So the practical configuration for most people is: web for doing things, app installed and logged in for being told about them.

Different surfaces, different attacks

The usual framing is "which is safer", and it has no answer, because the two surfaces fail in different ways. Knowing which way each one fails is more useful than a ranking.

What goes wrong in a browser

• Look-alike domains. A character substituted, a different suffix, a plausible subdomain. The page is a perfect copy and the address bar is the only tell. This is why the bookmark habit exists: a bookmark cannot be typo-squatted.
• Sponsored search results. Paid placements above the real result have been used repeatedly to serve phishing pages for financial sites. If you search for the platform by name, the first result is not necessarily the platform.
• Browser extensions. An extension with permission to read and change data on every site is, by construction, able to rewrite what you see on an exchange page — including an address you are about to copy. Extensions also change hands and get updated by whoever bought them.
• Clipboard interference. Malware that swaps a copied wallet address for another one is old, cheap and still effective, because nobody re-reads a long string they just pasted.

What goes wrong on a phone

• Counterfeit apps. Convincing listings appear in stores and on third-party download sites, and the more convincing ones survive long enough to matter.
• Everything else on the phone. Accessibility permissions, screen-recording permissions and notification access are all things an ordinary-looking app can request, and all of them defeat the security of any other app on the device.
• The device is also your second factor. If the authenticator, the SMS number and the app all live on one phone, the phone is a single point of failure — not just for theft, but for a cracked screen on a bad day.
• Shoulder surfing and notification previews. A balance or a verification code visible on a lock screen in a public place is a real, boring, frequent leak.

Read those two lists next to each other and the sensible conclusion is not to pick a winner. It is that the browser risks are mostly about reaching the wrong destination, and the phone risks are mostly about the device itself. The countermeasures are correspondingly different: bookmarks and a clean extension list on one side, permission hygiene and a second authenticator device on the other.

Where you get the app from

Fake exchange apps are a persistent category, and they are effective because they are pixel-accurate. They tend to arrive by one of three routes: a link in a message, a sponsored search result, or a third-party APK site.

The habit that closes all three: get the download link from the exchange's own download page or help centre, reached by typing the address yourself or using your own bookmark, then follow it into the official app store. Never install from a link someone sent you, and never from a search advertisement.

We used to phrase this as "only install from the official channel." That wording is worse than useless, because "official channel" is precisely what a fake site calls itself. The instruction has to name the thing you can independently verify — the exchange's own domain, typed by you — rather than a label anyone can claim.

One more, for the same reason: an app that asks for your seed phrase, your private key or an API key from another platform is not an exchange app, whatever it looks like.

A setup that uses both properly

Putting the whole page into something you can actually configure in ten minutes:

1. Bookmark the real site once, from an address you typed yourself. Then use only the bookmark, forever. This single habit removes the entire look-alike-domain category, and it costs nothing after the first time.
2. Install the app from the link on that bookmarked site. Not from a search, not from a message, not from an APK mirror.
3. Turn on push notifications and leave them on. They are the alarm attached to your whitelist delay. Then hide the content of notifications on the lock screen, so the alarm is visible and the detail is not.
4. Put the authenticator somewhere other than your only phone — a second device, or an authenticator that syncs, with the recovery codes on paper. The rest of your security setup rests on this one and it is the piece most often left as a single point of failure.
5. Audit your browser extensions once. Remove anything you do not actively use. Then decide whether the browser you use for the exchange is the same one you use for everything else; for some people the cleanest answer is that it is not.
6. Do withdrawals sitting at a desk. Not as a rule about screens — as a rule about attention. The mistakes on this page are almost all attention mistakes wearing a technical costume.

Our position, stated plainly because a comparison article that refuses to conclude is a waste of your time: web for anything irreversible, app for anything time-sensitive. Everything above is a consequence of that one line. The order-by-order details of what each mistake costs are in which chain to withdraw on and account security.
