@walletconnect/utils
Advanced tools
@walletconnect/utils is a utility library for WalletConnect, providing various helper functions to facilitate the development of WalletConnect integrations. It includes utilities for encoding, decoding, and other common operations needed when working with WalletConnect.
Encoding and Decoding
This feature allows you to encode and decode data, which is useful for transmitting data securely between clients and servers.
const { encode, decode } = require('@walletconnect/utils');
const data = 'Hello, WalletConnect!';
const encodedData = encode(data);
const decodedData = decode(encodedData);
console.log(encodedData); // Encoded data
console.log(decodedData); // 'Hello, WalletConnect!'
Hex Conversion
This feature provides functions to convert numbers to hexadecimal strings and vice versa, which is often needed in blockchain and cryptographic applications.
const { toHex, fromHex } = require('@walletconnect/utils');
const number = 255;
const hexString = toHex(number);
const numberFromHex = fromHex(hexString);
console.log(hexString); // '0xff'
console.log(numberFromHex); // 255
Random Bytes Generation
This feature allows you to generate random bytes, which can be used for creating secure keys or nonces.
const { generateRandomBytes } = require('@walletconnect/utils');
const randomBytes = generateRandomBytes(16);
console.log(randomBytes); // Random 16 bytes
Ethers.js is a library for interacting with the Ethereum blockchain and its ecosystem. It provides utilities for encoding, decoding, and other cryptographic operations, similar to @walletconnect/utils, but with a broader focus on Ethereum-specific functionalities.
