<p>Hey, most blockchain explorers offer the search of the btc chain. I use mempool.space, Blockchair.com or not so well working and a littel fishy: blockchain.com/explorer.</p><p>mempool dot space worked best for your example!</p><p><br></p>

<p>there are several block explorers that offer the ability to search for Bitcoin addresses using partial strings. Here are a few options:</p><ol><li>Blockchair (<a href="https://blockchair.com" target="_blank">https://blockchair.com/</a>): Blockchair is a popular block explorer that allows you to search for Bitcoin addresses using partial strings. Simply enter the partial string in the search bar, and Blockchair will return a list of matching addresses. You can also filter the results by transaction count, balance, and other criteria.</li><li>Blockchain.com (<a href="https://www.blockchain.com" target="_blank">https://www.blockchain.com/</a>): Blockchain.com is another well-known block explorer that offers partial string search for Bitcoin addresses. Simply enter the partial string in the search bar, and Blockchain.com will return a list of matching addresses. You can also filter the results by transaction count, balance, and other criteria.</li><li>BTC.com (<a href="https://btc.com" target="_blank">https://btc.com/</a>): BTC.com is a block explorer and cryptocurrency wallet that also offers partial string search for Bitcoin addresses. Simply enter the partial string in the search bar, and BTC.com will return a list of matching addresses.</li></ol><p>All of these block explorers are free to use and provide a wealth of information about Bitcoin transactions, addresses, and blocks.</p>

<p><br></p><p>It's not possible to search for Bitcoin addresses that contain a certain string directly, as Bitcoin addresses are a complex mix of random numbers and letters.</p><p>However, if you're looking for transactions that involve a specific string or keyword, you could use a blockchain explorer tool like blockchain.com, Blockchair, or BTC.com. These tools allow you to search for transactions by entering a keyword or string in the search field, and the tool will return a list of transactions that match your search criteria.</p><p>Keep in mind that searching for a keyword or string in transactions doesn't necessarily mean that the address itself contains that string. It's possible that the string is present in the transaction description or memo field instead.</p>
