SDK vs. APIs: Why We Chose to Build an SDK

At Chorus One, we prioritize security, transparency, and user control. Our decision to develop an SDK over a traditional API was driven by the following considerations:

Enhanced Security

• Local Transaction Building and Signing: Users can generate and sign transactions locally on their devices, ensuring that private keys are not exposed to external environments.
• Reduced Risk of Exposure: Keeping private keys within the user’s environment minimizes the risk of exposure to malicious actors.

Verifiable Trust and Transparency

• Direct Verification: Users can directly specify and verify the validator addresses they interact with, ensuring transparency and control over staking activities.
• Elimination of External Dependencies: The SDK approach removes potential attack vectors associated with relying on external APIs, enhancing overall trust and security.

Open-Source and Auditable

• Open-Source Code: The Chorus One SDK is open-source, allowing users and developers to review, audit, and contribute to the codebase. This openness ensures that the SDK is transparent and trustworthy.

💡 Why does it matter?

Choosing the Chorus One SDK means prioritizing security, transparency, and user empowerment. With local transaction building and signing, and open-source transparency, users can confidently participate in staking activities across supported networks.
