Example Request

PHP

// Replace these with your actual data
$url = "https://dev-site.evelar.energy/api/v1/transactions/estimate";

$secret = "MYSECRET";
$body = json_encode([
    "from" => "address1",
    "to" => "address2",
    "amount" => "5"
]);

// Generate the signature
$sign = hash('sha256', $body . $secret);
