Is it safe to share your crypto wallet address?
Nobody can drain your wallet with your public address. They can read your whole transaction history, though, and that deserves more thought.

Nobody can move your funds just because they know your public address. It works like a bank account number: it lets people pay you, and that's all it does.
What people underestimate is how much it shows. Your address opens your full transaction history to anyone with a block explorer, and once your name is attached, that history is attached to your name.
What can I share, and what can't I?
| What it does | Share it? | |
|---|---|---|
| Public address | Receives payments | Yes |
| Private key | Signs transactions for one address | Never |
| Seed phrase | Restores the entire wallet | Never |
No one needs the last two to send you money. Treat any request for them as an attempt at theft, including one from a polite "support agent".
Should I post my main wallet?
We wouldn't. If you've held crypto for a while, your main wallet tells a long story: what you own, when you bought, who you've paid. Create a separate wallet for public payments and move funds out of it now and then. Those transfers are visible on-chain too, so this reduces exposure rather than removing it, but a stranger looking up your payment address won't see your full balance on the first click.
Why did unknown tokens show up in my wallet?
Publishing an address attracts spam. Tokens you never asked for often link to a site that asks you to "claim" something, and that site is after a wallet approval. Ignore them. They can sit in your wallet harmlessly as long as you don't interact with them.
What is address poisoning?
A scammer sends you a tiny or zero-value transaction from an address that starts and ends like one you've used before, so it shows up in your history. Next time you copy from that history, you may pay them instead. Copy addresses from the original source, and check more than the first and last few characters.
Can someone pretend to be me?
Yes, and for anyone with an audience this is often the bigger worry. A fake profile with the attacker's address looks the same as a real one to a fan who wants to tip you. Keep one official link and repeat it everywhere so people learn it. On WalletTree, well-known names are protected and anyone can report an impersonator.
