## Overview <a href="#overview" id="overview"></a>

The **Circular Enterprise APIs** provide a powerful and efficient way to **certify data on the blockchain**, ensuring immutability, transparency, and security. These APIs facilitate **account management, network configuration, data signing, and transaction monitoring**, making it easier for enterprises to integrate blockchain-based certification into their workflows.

This library is designed for developers who need to verify, sign, and submit **data certificates** using the **Circular blockchain** while maintaining seamless integration with **Javascript applications**.
