The wallet's security depends less on Telegram as a container than on how you log in, who can reach your accounts and what happens if your phone is unlocked. Here is what protects your money and what does not.

Telegram is only the place where the wallet opens. Nexus Pay is a crypto wallet with a Visa card that you launch through a bot in Telegram, and it is not a bank. When you sign in, Telegram or Google sends a signed response and the server verifies it. That means there is no password to guess, reuse or lose. The flip side is that your access is tied to the account that signs you in.
An unlocked phone is the simplest way for a stranger to open an app. For this case the app has an optional four-digit access code that can be required every time it opens. It is not on by default, so you need to switch it on yourself. Separately, the card only spends the available balance, with no credit and no overdraft, and it can be frozen and unfrozen in the app in one tap.
This is the main risk to understand. Whoever gains access to your Telegram or Google account can reach the wallet, so the security of those accounts matters directly. A Google login can be linked as a second way in, which is convenient but also means a second account to protect. Use every protection those services offer and never share login codes with anyone. The access code adds one more barrier on the device itself.
The main share of crypto funds is kept in wallets without a permanent network connection. This reduces exposure to attacks over the network, because most of the money is not sitting in a permanently connected system. It does not make the service invulnerable, and it does not protect you from mistakes on your side. It is one layer among several, not a guarantee.
Blockchain transfers are irreversible: nobody can bring back a transfer sent to the wrong address. Each deposit address belongs to one network, and a coin sent through a different network than the address was issued for will not arrive and cannot be returned. Deposits below the minimum shown in the app are not credited either. This is general information, not a security guarantee, and no provider can promise absolute protection.
| Risk | What helps | What you do |
|---|---|---|
| Unlocked phone in the wrong hands | Optional four-digit access code | Switch it on in the app |
| Access to your Telegram or Google account | Security of those accounts themselves | Protect both accounts and never share login codes |
| Password guessing or loss | No password: signed login verified by the server | Nothing to remember or store |
| Attacks on stored funds over the network | Main share kept in wallets without a permanent network connection | Nothing; this is a layer on the service side |
| Transfer to the wrong address or network | Nothing can reverse it | Check the network, address and minimum before sending |
