Creating Wallets

How to create wallets using the CLI or programmatically

Although wallets are commonly created through the Elrond Web Wallet or the Elrond Ledger App, one can also use the CLI or the SDK.

Generate a new mnemonic

Using erdwalletjs-cli, a mnemonic phrase (24 words) can be generated as follows:

erdwalletjs new-mnemonic --mnemonic-file=mnemonicOfAlice.txt

Programmatically using elrond-core-js, the same can be achieved through:

const core = require("@elrondnetwork/elrond-core-js");

let account = new core.account();
let mnemonic = account.generateMnemonic();
console.log(mnemonic);

Deriving a JSON key-file (from mnemonic)

Using erdwalletjs-cli, a JSON key-file can be obtained as follows:

erdwalletjs derive-key --mnemonic-file=mnemonicOfAlice.txt \
 --account-index=0 \
 --key-file=keyOfAlice.json --password-file=passwordOfAlice.txt

Programmatically using elrond-core-js, the same can be achieved through:

const fs = require("fs");
const core = require("@elrondnetwork/elrond-core-js");

let mnemonic = "foo bar ...";
let password = "pass for JSON key-file";
let accountIndex = 0;

let account = new core.account();
let privateKeyHex = account.privateKeyFromMnemonic(mnemonic, false, accountIndex.toString(), "");
let privateKey = Buffer.from(privateKeyHex, "hex");
let keyFileObject = account.generateKeyFileFromPrivateKey(privateKey, password);
let keyFileJson = JSON.stringify(keyFileObject, null, 4);

fs.writeFileSync("myKeyFile.json", keyFileJson);
