Examples

Encode

let bip39Address = new Bip39Address();

const type = TypeBip39Address.ASCII; // 2
const topic = 'key';
const payload = 'Hello World';
let address = bip39Address.encode(type, topic, payload);
console.log(address); // 0248656c6c6f20576f726c64016b65790165b525

Decode

let bip39Address = new Bip39Address();
let helpHex = new HelpHex();
let classIEEE754 = new IEEE754();

const address = '0248656c6c6f20576f726c64016b65790165b525';

    const textHex = objBip39Address.payload;
    let text = "";
