Address Emoji Checksum

The Emoji Checksum Package provides tools for validating blockchain addresses (Ethereum, Bitcoin, Solana) and generating unique emoji-based checksums for addresses or arbitrary strings. This package is perfect for creating visually distinct representations of blockchain addresses.

Features

• Address Validation:

  • Supports Ethereum (with optional checksum validation).
  • Supports Bitcoin.
  • Supports Solana.

• Emoji Checksum Generation:

  • Configurable emoji checksum length.
  • Works with or without address validation.
  • Includes 325 curated unique emojis for creating checksums.

• Validation Flexibility:

  • Option to skip address validation for generating emoji checksums for arbitrary strings.

Installation

Install the package via npm:

npm install address-emoji-checksum

Usage

Import the Functions

import { generateEmojiChecksum, validateAddress } from 'address-emoji-checksum';

Generate Emoji Checksum

const checksum = await generateEmojiChecksum(
  '0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045',
  'ETH',
  4, // Optional length of checksum
  true // Enable checksum validation
);

console.log(checksum); // Outputs: 🥥 💿 🐌 ⚓

Address Validation

You can validate addresses separately if needed:

import { validateAddress } from 'address-emoji-checksum';

const isValidETH = validateAddress('0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045', 'ETH', true);
console.log(isValidETH); // true

const isValidBTC = validateAddress('bc1qjasf9z3h7w3jspkhtgatgpyvvzgpa2wwd2lr0eh5tx44reyn2k7sfc27a4', 'BTC');
console.log(isValidBTC); // true

const isValidSOL = validateAddress('4v1sJzGTVhu8N2G7JwVjqXYhn3Lh4AjdTZF7biMVePDB', 'SOL');
console.log(isValidSOL); // true

Examples

Generate Checksums for Various Networks

const ethChecksum = await generateEmojiChecksum('0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045', 'ETH');
console.log(ethChecksum); // Outputs: 🥥 💿 🐌 ⚓

const btcChecksum = await generateEmojiChecksum('bc1qjasf9z3h7w3jspkhtgatgpyvvzgpa2wwd2lr0eh5tx44reyn2k7sfc27a4', 'BTC');
console.log(btcChecksum); // Outputs: 🕌 🍋 👻 🚢

const solChecksum = await generateEmojiChecksum('4v1sJzGTVhu8N2G7JwVjqXYhn3Lh4AjdTZF7biMVePDB', 'SOL');
console.log(solChecksum); // Outputs: 🍷 🥨 🧙 🌧️
