Quick answer
In a non-custodial wallet like My Wallet, you hold the keys, so security is in your hands. Back up your seed phrase offline, install the app only from official links, turn on a password and biometrics, and never sign a request you didn't start. Blockchain transfers can't be reversed.
1. Protect your seed phrase
- Write it down offline and keep it private.
- Never photograph it on the device that runs your wallet.
- Never share it. Official support (@mysupport) never asks for it.
2. Download from official sources
- Desktop: mywallet.io
- Android: Google Play. The package ID is
org.mytonwallet.app. That's expected, and it's the official app. - iOS: Apple App Store.
- Telegram Mini App: @myapp.
3. Lock the app
My Wallet offers:
- Password for access and confirmations.
- Face ID / Touch ID where available.
- Auto-lock after a period of inactivity.
- Manual lock (on desktop: Ctrl/Cmd + Shift + L).
4. Check every transaction
- Look at the address, amount, network, and fee before you confirm.
- Watch for unknown addresses or unusual data in a request.
- When in doubt, cancel.
5. Watch for address poisoning
- Scammers send tiny transfers from look-alike addresses.
- My Wallet marks detected look-alike transfers with a Scam label.
- Turn on Hide Tiny Transfers in Settings → Assets & Activity.
- Use Saved Addresses for people you pay often, and check the full address.
6. Be careful with dapps
- Connect only to dapps you trust.
- My Wallet checks whether a TON Connect request comes from the domain it claims and shows a warning if not.
- Disconnect sites you no longer use in Settings → Connected Sites.
7. Split your funds
- Don't keep everything in one wallet.
- Use a separate wallet for games and lesser-known projects.
- For long-term holdings, you can create an offline wallet without connecting to the internet.
8. Keep your device healthy
- Install OS and app updates.
- Avoid installing apps from unknown sources.
- Lock your phone with a strong passcode.

FAQ
Is a non-custodial wallet safe?
It can be, if you follow the habits above. You control the keys, which also means nobody can recover them for you.
What should I do if my phone is lost?
Restore your wallet on a new device with your seed phrase. If you think the phrase was exposed, create a new wallet and move your funds.
Does My Wallet ever message users first?
No. Official support never reaches out first, never asks for your seed phrase, and never asks you to enter sensitive data through third-party links.
Can a blockchain transfer be reversed?
No. Double-check every address before you confirm.
