  Validating cryptocurrency wallet addresses in JavaScript can be done using regular expressions. Here are some regular expressions that you can use: 1. Bitcoin (BTC) address: /^(bc1|[13])[a-zA-HJ-NP-Z0-9]{25,39}$/ 2. Ethereum (ETH) address: /^0x[a-fA-F0-9]{40}$/ 3. Ripple (XRP) address: /^r[0-9a-zA-Z]{24,34}$/ 4. Litecoin (LTC) address: /^[LM3][a-km-zA-HJ-NP-Z1-9]{26,33}$/ These regular expressions cover the most common types of cryptocurrency wallet addresses. You can use them to validate the addresses entered by users and ensure that they follow the correct format. Remember to always validate user input on the server-side as well to prevent any potential security vulnerabilities. Additionally, consider implementing additional checks, such as checksum validation, to further enhance the accuracy of address validation.
