What is a crypto wallet address? How to send crypto safely
By SendPay Business · · 2 min read
A crypto wallet address is a long string of letters and numbers that works like an account number: it tells the network where to send crypto. You can share it freely, because it only lets people send to you, not take from you.
Address vs private key
The address is public, like an account number. The private key is secret and proves you own the coins at that address. Anyone with the private key can move the coins, so it must never be shared.
Checks before you send
- Copy and paste the address rather than typing it, then check the first and last few characters.
- Make sure you're sending on the right network, as the same coin can exist on more than one.
- Send a small test amount first when using a new address.
Why mistakes are costly
Crypto transfers usually can't be reversed. Crypto sent to the wrong address or on the wrong network may be lost for good, which is why careful checks matter.
