3、Tron Identity and address

TronSmartWallet Development packages use Credential Object to represent a specific Tron identity certificate , This object contains the key and address information of the account .

3.1 Instantiation Credential

Use static methods create() Create a new Ethereum account , for example ：

//use TronSmartWallet\Credential;

$credential = Credential::create();                          //  Create a new account 

You can also use static methods fromPrivateKey() Import an existing private key to instantiate Credential object , for example ：

$credential = Credential::fromPrivateKey(
  '4f3edf983ac6......b113bce9c46'                       //  Private key to import 
);

3.2 Check your account key and address

Credential Class provides the following methods to obtain the private key of the current account 、 Public key and address ：

• privateKey() ： Return the private key 16 Base string
• publicKey() ： Return public key 16 Base string
• address() ： return Address object

for example , The following code creates a new Tron ID card and show its address ：

$credential = Credential::new();
echo 'address => ' . $credential->address() . PHP_EOL;  //  Show account address 

3.3 Tron address translation

stay Tron In blockchain , There are two expressions for an address ：16 Into the system and base58 Express , For example, here are two representations of the same address ：

• Base58 ：TDN3QY85Jft3RwgyatjRNmrwRmwkn8qwqx
• 16 Base number ：412539EF4F3EB733C105A957EEBB20FD60AD8C9A43

Address Class contains the corresponding encoding and decoding logic , The address format can be easily converted . for example ：

//use TronSmartWallet\Address;
$a1 = Address::decode('TDN3QY85Jft3RwgyatjRNmrwRmwkn8qwqx');         // decode Base58 Address 
echo $a1 . PHP_EOL;             // Output ：412539EF4F3EB733C105A957EEBB20FD60AD8C9A43
$a2 = Address::encode('412539EF4F3EB733C105A957EEBB20FD60AD8C9A43'); // code 16 Base address 
echo $a2 . PHP_EOL;             // Output ：TDN3QY85Jft3RwgyatjRNmrwRmwkn8qwqx

4、 Use TronApi

TronApi A variety of Tron Nodes provide API, for example tron All the nodes 、solidity Node and event service node API,TronSmartWallet utilize TronApi visit Tron Blockchain .

Instantiation TronApi when , It can be divided into different types of Tron Nodes specify different connections URL, for example ：

//use TronSmartWallet\TronApi;

$api = new TronApi(
  'https://api.trongrid.io',       // All the nodes URL
  'https://api.trongrid.io',       // Contract node URL
  'https://api.trongrid.io'        // Event node URL
);

When the above three nodes URL Phase at the same time , I could just write it as ：

$api = new TronApi('https://api.trongrid.io');

If I use theta Tron Official TronGrid node , So you can use it directly TronApi Two static functions provided mainNet() and testNet(), Access the main chain and shasta Test chain .

for example , The following code is equivalent ：

$api = new TronApi('https://api.trongrid.io');
$api = TronApi::mainNet();                       // Equivalent to the above 

$api = new TronApi('https://api.shasta.trongrid.io');
$api = TronApi::testNet();                       // Equivalent to the above 

5、SmartWalletKit Class

3.1 Instantiation SmartWalletKit

SmartWalletKit yes TronSmartWallet The entry class of the development package , When instantiating, you need to pass in TronApi object 、Credential Object and factory contract address . for example ：

//use TronSmartWallet\TronApi;
//use TronSmartWallet\Credential;
