 ## 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
