It includes classes and helper functions to interact with the Circular network, submit certificates, retrieve transactions, and manage accounts. Features -------- [](#features) - **Data Certification**: Submit data to the blockchain for certification. - **Transaction Retrieval**: Fetch transaction details by ID or block range. - **Account Management**: Open, update, and close accounts. - **Secure Signing**: Sign data using elliptic curve cryptography (secp256k1). - **Network Integration**: Connect to different blockchain networks (mainnet, testnet, devnet). --- Installation ------------ [](#installation) You can install this library using **Composer** or by **cloning the repository**. ### Option 1: Install via Composer (Recommended) [](#option-1-install-via-composer-recommended) 1. Run the following command in your project directory: ``` composer require circularprotocol/circular-enterprise-apis ``` 2. Include the Composer autoloader in your PHP script: ``` require_once __DIR__ . '/vendor/autoload.php'; ``` ### Option 2: Clone the Repository [](#option-2-clone-the-repository) 1. Clone the repository: ``` git clone https://github.com/circular-protocol/circular-php.git cd circular-enterprise-apis ``` 2. Install dependencies using Composer: ``` composer install ``` 3. Include the autoloader in your PHP script: ``` require_once __DIR__ . '/vendor/autoload.php'; ``` --- Usage ----- [](#usage) ### 1. Opening an Account [](#1-opening-an-account) To open an account and retrieve account details: ``` use Circularprotocol\Circularenterpriseapis\CEP_Account; $account = new CEP_Account(); $account->open('a4fc8b11bfc5dc2911ab41871e6de81f500fe60f3961343b202ad78e7e297ea08'); echo "Account opened successfully.\n"; ``` ### 2. Chosing a network and the blockchain: [](#2-chosing-a-network-and-the-blockchain) ``` $blockchain = 'blockchain-address'; $account->setNetwork("testnet"); // chose between multiple networks such as testnet, devnet and mainnet $account->setBlockchain($blockchain); ``` ### 3. Retrieve account informations [](#3-retrieve-account-informations) Update account informations such as Nonce: ``` if($account->updateAccount()){ //... } ``` ### 4. Submitting a Certificate [](#4-submitting-a-certificate) To submit data for certification: ``` $pdata = 'Your data to certify'; $privateKey = 'your_private_key_here'; try { $response = $account->submitCertificate($pdata, $privateKey); print_r($response); } catch (Exception $e) { echo "Error: " . $e->getMessage(); } ``` ### 5. Retrieving a Transaction [](#5-retrieving-a-transaction) To fetch transaction details: ``` //... $resp = $account->getTransactionOutcome($txID, 10); if ($resp["BlockID"]) { $blockID = $resp["BlockID"]; $status = $account->getTransaction($blockID, $txID); if ($status == 200) { echo "Transaction Status: " . $status["Response"]["Status"] . "\n"; $account->close(); } else { echo "Error on retrieving transaction"; } } else { echo "Error on retrieving transaction status"; } //... ``` --- Helper Functions ---------------- [](#helper-functions) - **`hexFix(string $hex)`**: Removes `0x` from hexadecimal strings. - **`stringToHex(string $string)`**: Converts a string to its hexadecimal representation. - **`hexToString(string $hex)`**: Converts a hexadecimal string back to a regular string. - **`getFormattedTimestamp()`**: Returns the current timestamp in `YYYY:MM:DD-HH:MM:SS` format. --- Example Workflow ---------------- [](#example-workflow) 1. Open an account. 2. Set network and blockchain info 3. Submit data for certification. 4. Retrieve the transaction ID from the response. 5. Fetch transaction details using the TxID and the BlockID. ``` ``` --- Contributing ------------ [](#contributing) Contributions are welcome! If you'd like to contribute, please follow these steps: 1.
