What a crypto wallet is
A crypto wallet doesn't hold coins: it holds the key that proves they're yours. The address is safe to share; the seed phrase never is.
Coins live on the blockchain
A blockchain is a public record everyone can read. Your coins are entries in it, attached to your address. A wallet app is what lets you use them.
Address: like an account number
Your address (bitcoin's start with bc1, ether's with 0x, Tron's with T) is how people send you coins. It's safe to share: anyone can see what's there, and that's how Allown follows a wallet without any keys.
Seed phrase: the one secret
When you set a wallet up, it shows 12 or 24 words: the seed phrase. Whoever has those words owns the coins. Write them on paper, keep it safe, and never type them into a website, a chat or an app that asks, including ones that look official.
Exchange or own wallet
Coins on an exchange are held for you by the exchange. Coins in your own wallet are held by you alone: safer from an exchange's troubles, but lost for good if the seed phrase is lost.
