A public address or public key is a cryptographic code that allows a user to receive cryptocurrencies into his or her account. The public key coupled with the private key are significant tools required to ensure the security of the crypto economy.

Everyone who owns cryptocurrencies (bitcoin, ethereum, …) has to have a unique identifier or address - similar to as you would have with a bank account.

The public address of your Wallet allows you to receive cryptocurrency from other wallets or external transactions.

What does this address look like?

It is a long series of numbers and letters like this one - mine, for example, is this:

Bitcoin Public Address:


Ethereum Public Address:


You are also given a Quick Response code (or QR code). You can send that to people, or they can scan it with the camera function on their smartphone or other device using a mobile wallet application to easily access your wallet address.

Should I worry about putting that on a public website!?

Not at all! This address is safe to give to anyone. It is like publishing your bank account number (IBAN), all you can expect is that someone sends you money. People can’t access your wallet at all if you publish your PUBLIC ADDRESS. So feel free to send me bitcoins if you wish! I will be very happy :).
