PHP TRON Wallet API

This is an implementation of the TRON protocol in PHP using GRPC.

Documentation

If new to protocol buffers or GRPC start with the following documentation:

1. Google Protocol Buffers documentation
2. GRPC PHP documentation

Examples

List witnesses

$wallet = new \Protocol\WalletClient('47.91.216.69:50051', [
   'credentials' => Grpc\ChannelCredentials::createInsecure()
]);

$emptyMessage = new \Protocol\EmptyMessage();

/* @var \Protocol\WitnessList $witnesses */
list($witnesses, $options) = $wallet->ListWitnesses($emptyMessage)->wait();

$base58 = new Tuupola\Base58;

/* @var \Protocol\Witness $witness */
foreach ($witnesses->getWitnesses() as $witness) {
    var_dump($base58->encode($witness->getAddress()));
}

Scan the blockchain

$wallet = new \Protocol\WalletClient('47.91.216.69:50051', [
    'credentials' => Grpc\ChannelCredentials::createInsecure()
]);

$n = 15523;
do {
    $numberMessage = new \Protocol\NumberMessage();
    $numberMessage->setNum($n--);
    list($block, $meta) = $wallet->GetBlockByNum($numberMessage)->wait();
    /* @var \Protocol\Block $block */
    $transactions = $block->getTransactions();
} while(!$transactions->count());

var_dump(sprintf('block #%d seems to have %d transactions!', $n, $transactions->count()));

Development

To update PHP files according to the TRON protocol install protoc and run

sudo bash ./genphp.sh

Issues

• Encoding and crypto utilities
• Unit tests
• Proper namespacing of protocol and metadata classes e.g. Tron\Protocol\Account instead of Protocol\Account
• Add proper @return tags and type hinting (this is a protoc issue? docblocks could be improved to remove the need for inline typehinting)
