Xiaoyi NEO blockchain wallet account

Wallet account

The neo wallet mainly includes address, privateKey, publicKey, scriptHash, and WIF; there is a certain conversion relationship between them: NEP<=>WIF
<=> Private => Public => ScriptHash <=> Address is no joke, except address
Don’t tell anyone else except what you can tell others. The address is similar to a bank card number, which is used when others want to transfer money to you.

Create wallet account

import { wallet } from '@cityofzion/neon-js';/  Generate a new neo account based on passpase 
@param {} passphase  @param {} confirmPassphase  @param {} wif /export
function createWalletAccount(passphase: string, confirmPassphase: string,
wif?: string): ?WalletAccount { if (passphase !== confirmPassphase) return
null; var account = new wallet.Account(wif || wallet.generatePrivateKey());
const encryptedWIF = wallet.encrypt(account.WIF, passphase); const result:
WalletAccount = { address: account.address, privateKey: account.privateKey,
publicKey: account.publicKey, scriptHash: account.scriptHash, WIF:
account.WIF, encryptedWIF, passphase, } return result;}

Create wallet account unit test

Unit test the method of creating a wallet through jest test('createWalletAccount ', () => { const passphase =
'123456'; const account = createWalletAccount(passphase, passphase);
console.log(account); expect(account.address !==
null).toBe(true);});The running result is as follows, which is the currently generated account information. You can use neo-wallet to log in and try it. {address:
'AUMgtJsw3kBrcA7poBYNaonZTGMNoqZNLy', privateKey:
'10bb026b4015c481f0b5142aa5de36de40a99fc8c26e956011a3f820f7708fba', publicKey:
'03af2ad8725c4926632d6816f5502d8f749dec369afadfe0bb5ac697fe22a0ef77',
scriptHash: 'a8f677c132f2c82d73ff138e817e784c25ab068a', WIF:
'KwnETPM2m8wTAY3qySvDVLf3Vpfg77nvJhxR2Qyi8uMWKoqP1Q3f', encryptedWIF:
'6PYVHykkA1TfyQ2344wftv5e7vRoecV4iVwEVZ62aqCAx3dh3LDrRV19AS', passphase:
'123456' }

Convert

As mentioned before, various data in the wallet have certain conversion relationships. As for the detailed principles of mutual conversion, we will not discuss them first. We can use neon-
js related API to check whether the conversion is correct. NEP<=>WIF <=> Private => Public => ScriptHash <=>
Address: First create a new jtest unit test file Core.spec.js

Conversion of private key to public key

The test account generated above is used here for testing. Note that because it is a test account, I will not use it again, so it is exposed. If it is your personal account, please be sure not to expose the WIF and privateKey. The unit test code is as follows: import
{wallet} from '@cityofzion/neon-
js';test('private:10bb026b4015c481f0b5142aa5de36de40a99fc8c26e956011a3f820f7708fba
get PUb_Key',()=>{ const pubKey =
wallet.getPublicKeyFromPrivateKey('10bb026b4015c481f0b5142aa5de36de40a99fc8c26e956011a3f820f7708fba');
expect(pubKey).toBe('03af2ad8725c4926632d6816f5502d8f749dec369afadfe0bb5ac697fe22a0ef77');});Run the unit test using the command: npm
run test __test__/neo/Core.spec.js results:

All conversions

The complete conversion relationship is as follows: import {wallet} from '@cityofzion/neon-js'; const walletAccount = {
address: 'AUMgtJsw3kBrcA7poBYNaonZTGMNoqZNLy', privateKey:
'10bb026b4015c481f0b5142aa5de36de40a99fc8c26e956011a3f820f7708fba', publicKey:
'03af2ad8725c4926632d6816f5502d8f749dec369afadfe0bb5ac697fe22a0ef77',
scriptHash: 'a8f677c132f2c82d73ff138e817e784c25ab068a', WIF:

wallet.getAddressFromScriptHash(walletAccount.scriptHash);
expect(address).toBe(walletAccount.address); const scriptHash =
wallet.getScriptHashFromAddress(walletAccount.address);
expect(scriptHash).toBe(walletAccount.scriptHash);});

Summarize

As above, it mainly explains the creation of neo account and the conversion relationship between the various fields of the account. The API used in this article is neon-
js, this is the neo wallet API open sourced by coz in the github community. It contains all the APIs for wallet development. I think it is a good material for learning wallets. Of course, neo-gui, neo-
cli itself is also open source, and you can use their source code to learn. However, compared to C, for developing cross-platform applications, I prefer electron-based solutions. In order to learn to develop neo wallet, I built an electron boilerplate as the basis for quick start, so that other friends who also want to use this solution do not have to set up the environment again. This boilerplate specifically integrates the following technical solutions: electron, React, dva, flow, antd; I will take the time to integrate the jest mentioned in the article later so that I can write unit tests out of the box.
