Installation

composer require php-core/wert-sc-signer

Usage

Standard PHP

use PHPCore\WertScSigner\WertScSigner;

$signedData = WertScSigner::signSmartContractData($options, $privateKey);

Laravel

The package includes Laravel integration. The service provider and facade will be automatically registered.

Publish the configuration file:

php artisan vendor:publish --provider="PHPCore\WertScSigner\Laravel\WertScSignerServiceProvider" --tag="config"

Add your Wert private key to your .env file:

WERT_PRIVATE_KEY=your_private_key_here

Use the facade in your code:

use PHPCore\WertScSigner\Laravel\Facades\WertScSigner;

$dataWithSignature = WertScSigner::signSmartContractData($options);

Function signSmartContractData returns the given options array with an addition of a "signature" property. You can pass the result directly to WertWidget initializer.

Options

Property	Required	Type	Description
address	required	string	User's address that will act as a fallback address if a smart contract can't be executed. In case of fallback, Wert will transfer commodity_amount to this address
commodity	required	string	List of supported currencies
network	optional	string	List of supported currencies
commodity_amount	required	numeric	An amount of crypto necessary for executing the given smart contract
sc_address	required	string	The address of the smart contract
sc_input_data	required	string	Data that will be used for smart contract execution, in the hex format

Example

$commodity = 'ETH';
$network = 'ethereum';
$options = [
    // required generally:
    "partner_id" => "...",

    // required for signing:
    'address' => '0x742d35Cc6634C0532925a3b844Bc454e4438f44e', // NFT receipient
    'commodity_id' => strtolower($commodity) . '_' . strtolower($network) . '.sc.ethereum',
    'commodity' => $commodity,
    'commodity_amount' => 1.5,
    'network' => $network,
    'sc_address' => '0x...', // smart contract address
    'sc_input_data' => '...', // input data (learn more: https://docs.wert.io/docs/forming-input-data)

    // ...
];

$privateKey = 'your_private_key_here';
$dataWithSignature = WertScSigner::signSmartContractData($options, $privateKey);
