FuLink Developer Hub

Welcome to the FuLink Developer Hub! Whether you're a newcomer or an experienced developer, we have the tools and resources to support your journey in building on the FuLink network.


Overview of the FuLink Network


The FuLink network integrates the Application Layer, the Cryptography Layer, the Storage Layer, the Blockchain Layer and the Watcher Network.


Technical Features


Cutting-Edge Cryptography

FuLink employs advanced cryptographic techniques such as PRE, ZKP, and FHE, ensuring unparalleled data security and privacy for both users and developers.

Seamless Integration

Developers enjoy effortless integration with FuLink SDK and FuLink Agent SDK, enabling smooth communication between decentralized applications (DApps) and the FuLink network.

Blockchain-Powered Incentives

Establishes a transparent, traceable and robust reward system. Ensures a clear and verifiable record of rewards, fostering trust and accountability within our network.

Endpoint Encryption

Ensure ultimate data security with endpoint encryption, where data never leaves your device without proper authorization, ensuring a secure and private user experience.

FuLink Agent SDK

For developers looking to develop a privacy-preserving Dapp and seamlessly interact with the FuLink network, we recommend using the FuLink Agent directly.


Integrating the FuLink Agent-SDK into your Dapp enables communication between your Dapp and the FuLink Agent, acting as a web-based digital wallet.

Explore our "File Transfer" Dapp, an example showcasing the use of the FuLink Agent SDK. This demo highlights the seamless integration and functionality provided by the FuLink Application Layer, empowering developers to achieve secure file transfers and data sharing.

FuLink SDK

If you have a deeper understanding of the FuLink network and want to perform fundamental operations within your Dapp, the FuLink SDK is the ideal choice.

It allows you to keep all functions inside your Dapp without relying on external components.
