Usage example

Node

const WAValidator = require('@ramp-network/crypto-address-validator')

const valid = WAValidator.validate('1KFzzGtDdnq5hrwxXGjwVnKzRbvf8WVxck', 'BTC')

if (valid) {
  console.log('This is a valid address')
} else {
  console.log('Address INVALID')
}
// This will log 'This is a valid address' to the console.

const WAValidator = require('@ramp-network/crypto-address-validator')

const valid = WAValidator.validate('1KFzzGtDdnq5hrwxXGjwVnKzRbvf8WVxck', 'litecoin', 'testnet')

if (valid) {
  console.log('This is a valid address')
} else {
  console.log('Address INVALID')
}
// As this is a invalid litecoin address 'Address INVALID' will be logged to console.

Browser

<script src="wallet-address-validator.min.js"></script>

// WAValidator is exposed as a global (window.WAValidator)
const valid = WAValidator.validate('1KFzzGtDdnq5hrwxXGjwVnKzRbvf8WVxck', 'bitcoin')

if (valid) {
  alert('This is a valid address')
} else {
  alert('Address INVALID')
}
// This should show a pop up with text 'This is a valid address'.
