## 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

~~~ 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
