<p>Just a basic algorithm is used to determine wallet addresses. Addresses are merged together, if they are co-spent in one transaction.

<p>For example</p>
<p><a href="https://www.walletexplorer.com/wallet/03457b955f9c055c/addresses" rel="nofollow noreferrer">https://www.walletexplorer.com/wallet/03457b955f9c055c/addresses</a> shows all the addresses linked to wallet 03457b955f</p>
<p>How do they do that?</p>
<p>Thank you !!</p>

Just to make sure you're aware: there is no such thing as a unique wallet identifier in Bitcoin. The association between addresses and wallets is a *guess* by that website, and the 03457b955f is an identifier chosen by walletexplorer.com for the observed cluster of (presumed related) addresses.

Can I find a bitcoin wallet from an address directly from blockchain data? (not website)

(Asked by: username_0 on 2020-09-19)

For example

<https://www.walletexplorer.com/wallet/03457b955f9c055c/addresses> shows all the addresses linked to wallet 03457b955f

How do they do that?

Thank you !!
