AvN account generation¶

There are multiple ways of generating accounts to interact with the AvN blockchain. This document will highlight 2 of them.

Polkadot libraries can be used to generate accounts that are compatible with the AvN. The following example code demonstrates this.
index.js

const { Keyring } = require('@polkadot/keyring');
const { u8aToHex } = require('@polkadot/util');
const { cryptoWaitReady, mnemonicGenerate, mnemonicToMiniSecret } = require('@polkadot/util-crypto');

async function generateAccount(accountCrypto) {
 let crypto = accountCrypto || 'sr25519';

 if (!['ed25519', 'sr25519'].includes(crypto)) {
   throw (`Invalid account crypto "${crypto}" specified.`);
 }

 await cryptoWaitReady();

 const keyring = new Keyring({ type: crypto, ss58Format: 42 });
 const mnemonic = mnemonicGenerate();
 const keyPair = keyring.createFromUri(mnemonic);

 const key = {
   'Mnemonic': mnemonic,
   'PrivateKey': u8aToHex(mnemonicToMiniSecret(mnemonic)),
   'PublicKey': u8aToHex(keyPair.publicKey),
   'SS58Address': keyPair.address
 };

 console.log(JSON.stringify(key, null, 2));
}

(async () => {
   await generateAccount()
})()

package.json
{
   "dependencies": {
       "@polkadot/api": "^3.6.4",
       "@polkadot/keyring": "^5.0.1",
       "@polkadot/util": "5.0.1",
       "@polkadot/util-crypto": "5.0.1"
   }
}

To test the script run npm install from the same location as your package.json file. You can then execute the script by running node index.js
