Short answer: yes. Any software wallet (hot wallet) that holds private keys on a device can be drained if those keys or approvals are exposed. Phishing pages, fake dApps, and malicious approvals are the most common routes bad actors use to move funds out of a wallet. What I believe matters most is how you interact with dApps and which approvals you grant—those decisions are what put funds at risk.
When I first set this up, I almost clicked "approve unlimited" on a suspicious airdrop page. Thankfully I double-checked the transaction details and canceled. Small habits like that make a big difference.
Phishing for a software wallet usually looks the same: a copycat website (or app) asks you to connect, sign, or approve something. A fake dApp might mimic a popular swap or staking UI but submit a malicious contract call instead. Sometimes the attacker sends a message that urges immediate action — "claim now" — and that social pressure is the trick.
Fake dApp trust wallet attacks can happen through links in social channels, QR codes, or even spoofed support pages. The connection step is where the wallet hands over the power to a smart contract (via a token allowance). Once that allowance exists, a malicious contract can move approved tokens.
But remember: not every odd-looking page is malicious. The trick is to check the basics before you act.
And always keep a backed-up seed phrase offline. That step alone removes a lot of attack surface.

Malicious approvals are a frequent vector. Once you approve a token allowance, a contract can spend or move those tokens within the set limit. Here's a safe, general approach to check and revoke approvals:
Step-by-step to review allowances:
Revoke transactions cost gas. So yes, there’s a trade-off: the protection is worth the fee when an approval looks risky. If you’re unsure, move the remaining funds to a new wallet with a fresh seed phrase and no previous approvals.

Scam tokens often share telltale signs. Look for these checks before buying or interacting:
Avoid scam tokens trust wallet buyers often regret impulsive buys. Slow down. Verify addresses, check liquidity, and review token metadata through the explorer or trusted listings.
But be honest about expectations: recovery is rare. I’ve found that fast containment (moving safe assets, revoking approvals) is the most practical step.

Q: Is it safe to keep crypto in a hot wallet? A: Hot wallets trade off convenience for risk. They're fine for smaller balances and active DeFi use. For large holdings, consider splitting funds and keeping the bulk in a hardware wallet or cold storage. See security-features for more.
Q: How do I revoke token approvals? A: Use a block explorer to inspect active "Token Approvals" for your address, then submit a transaction to set questionable allowances to 0. If you need a guided walkthrough, see revoke-token-approvals.
Q: What happens if I lose my phone? A: If you have your seed phrase, you can restore your wallet on another device. If you don't, the funds are effectively lost. Store your seed phrase offline (paper or hardware) and read seed-phrase-backup for options. For steps after losing a device, read lost-phone-recovery.
Phishing, scam tokens, and malicious dApps are real risks, but they are manageable with consistent habits: check addresses, limit approvals, test with small amounts, and keep strong backups. I use throwaway addresses for risky interactions and keep larger balances offline. What I've found is that a few deliberate checks before every connect prevent most headaches.
