<p>In short, it’s a long string of numbers and letters indicating the blockchain “location” to and from which crypto is sent. That’s how it looks in OneArt wallet.</p><p><img src="https://academy-public.coinmarketcap.com/optimized-uploads/cab2ea8e8d194680a863331c6b630532.png" /></p><p>An address can also be represented as a QR code.</p><p><img src="https://academy-public.coinmarketcap.com/optimized-uploads/6de4910a6b2145c197e654b47c681de3.png" /></p><p>❗️Please note: on different blockchains, addresses come in different formats. For example, Ethereum addresses start with “0x” and consist of 40 hexadecimal characters. Bitcoin addresses have three main formats: P2PKH (starts with 1), P2SH (starts with 3), and bech32 (starts with bc1). Avalanche <a href="https://support.avax.network/en/articles/4596397-what-is-an-address" rel="noopener noreferrer nofollow">lets</a> virtual machines select an address format, and the address may look like</p><ul><li>X-avax1kdj07lhpx82h69snslkdei3tpc046ze68nok3g6</li><li>C-0x820891f8b80daf3ea7d7ce7932e6bba2dd5c8401</li><li>P-avax4bo2j9klyedp1akhgakjthducorhklqafalce6af6im.</li></ul><h2 id="header-0">Address &#61; public key?</h2><p>Not exactly. In most cases, it’s a shorter, compressed version of your public key. For example:</p><p><em>Ls902dgfb74c6c2dcba7e31c5b4972e2c7ec23d0ba7a3b843329763cb312af1 (private key) ➡️</em></p><p><em>07c5712e90673ed5cb5ba48b6fdaa21894d3a48a668923c1c85ba43763421f4531(public key) ➡️</em></p><p><em>1EUKFxdHNt3KY4waFUP6z2bytCgNPKRpfd (address).</em></p><p>❗️Stellar network <a href="https://stellarxhelp.zendesk.com/hc/en-us/articles/360052072031-What-is-a-Public-Key-" rel="noopener noreferrer nofollow">doesn’t make difference</a> between the address and public key. Here, you send funds to and from your public key.</p><h2 id="header-1">How it is generated</h2><p>It’s derived from a public key via the hash function. For example, Ethereum uses the <a href="https://www.oreilly.com/library/view/mastering-ethereum/9781491971932/ch04.html" rel="noopener noreferrer nofollow">Keccak-256 hash function</a>. It takes your private key, creates a hash of it, keeps the last 20 bytes, and adds 0x to show it is hexadecimal. It’s your address.</p><blockquote><em>0x &#43; the last 20 bytes of the private key that was hashed with Keccak-256 &#61; address</em></blockquote><blockquote><em>0x165cd37b4c644c2921454429e7f9358d18a45e14</em></blockquote><p>Bitcoin addresses have a checksum at the end. It’s added to help catch typos. To create a checksum in Bitcoin, data is hashed through the <a href="https://emn178.github.io/online-tools/sha256.html" rel="noopener noreferrer nofollow">SHA256 function</a> two times. The first four bytes of the result are your checksum. The chance you make a mistake and still get the right <a href="https://learnmeabitcoin.com/technical/checksum" rel="noopener noreferrer nofollow">checksum</a> is 1 to over 4 billion. Finally, Bitcoin converts it to <a href="https://learnmeabitcoin.com/technical/base58" rel="noopener noreferrer nofollow">Base58</a> to omit characters that are easy to make a mistake in, such as 0 and o, 1 and I.</p><blockquote><em>(Prefix &#43; hashed public key/script &#43; checksum) x encoded in Base58 &#61; address</em></blockquote><blockquote><em>1QMESBsqiu9hc37Y86</em>CGpwsrvHqjW7LZy</blockquote><h2 id="header-2">How many addresses can be generated from a single mnemonic?</h2><p>The number is almost infinite.</p><p>❗️Please note: to enhance security and privacy, Bitcoin changes your address after each transaction. But no worries! You won’t lose assets. All addresses are derived from a so-called extended public key associated with the same account. So, you don’t have to give your sender a new address.</p><h2 id="header-3">Can someone steal my crypto with my wallet address?</h2><p>The short answer to the question ‘Can my wallet address be hacked?’ is ‘No.’</p><p>Addresses are generated from public keys that are, in turn, derived from private keys. But it doesn’t work vice versa, i.e., you can’t derive a private key from an address or a public key.</p><p>So, it’s completely safe to share your address. Compare it to sharing your bank card number: it’s secure unless you reveal your CVV.</p><h2 id="header-4">Where is my address in OneArt?</h2><p>On the ‘Wallet’ screen.
