Plain English
A crypto address is the public identifier of a wallet — like an account number you can share to receive funds. It is derived from your public key and looks like a random string of letters and numbers.
How it actually works
Each address has a corresponding private key. To receive crypto, you share the address. To send crypto from the address, you sign the transaction with the matching private key. Addresses are public; transactions to and from them are visible on the blockchain. Privacy comes from not linking your real identity to a specific address.
What it means for you
Send the wrong address one digit and the crypto is gone — there is no reversal. Verify every address character before sending, especially for large amounts. Use the wallet’s address book and copy-paste, not retype.
We teach address verification protocols, address-poisoning attacks, and the use of ENS names (human-readable Ethereum addresses) to reduce error risk.
