Hello Cardano community,
We are excited to share with you Hydra SDK – https://sdk.hydrawallet.app/
a toolkit for developers, designed to make building DApps on Cardano faster, easier, and more user-friendly. This SDK is especially aimed at developers who want to leverage Hydra and WASM to create high-performance applications with seamless wallet integration.
Hydra SDK is built to serve developers who want to move fast and focus on what matters most: application logic.
DApp developers on Cardano who want to quickly integrate wallet functionality into their applications.
Frontend developers building Browser DApps (applications running directly on the web without needing complex plugins).
DApp developers, especially in GameFi, who want to explore Hydra, where WASM brings high speed and accuracy to real-time transactions.
Although Hydra still has many issues to address before releasing a stable 1.x version ready for developers, with version 0.22.4 we already have enough essential features to start experimenting and building products. I hope this toolkit will help us gather a team of developers to push this technology forward and achieve the original goals of the project.
With Hydra SDK, you will have ready-to-use features:
• Integrate Cardano wallets directly in the browser → no heavy reliance on external extensions.
• Sign transactions, manage keys/accounts, send/receive ADA & tokens, and interact with smart contracts / Plutus scripts.
• Compatibility with modern build tools such as Vite, Nuxt, Rollup → lowering the barrier for DApp integration.

3 Key Advantages
WASM → Speed & High Performance
Leverage WASM for fast transaction building and efficient computation.
Hydra Integration → Simple & Effective
Seamless interaction with Hydra without complexity.
Browser DApp Support Out of the Box
Works smoothly with modern web app technologies (Vite, Rollup, Nuxt, …).
The main goal of Hydra SDK is to empower DApp developers – especially Web2 game developers who want to enter the Web3/GameFi market on Cardano.
Instead of spending lots of time handling blockchain connections, wallet management, or the complexities of Hydra, developers can now focus entirely on building applications.
This SDK is an initiative from our Labs, developed after our own experience experimenting with application ideas and facing time-consuming difficulties. This is an early version, and there will definitely be many improvements to come. Therefore, we highly value feedback from the community – your contributions will be invaluable in shaping future releases.
We look forward to hearing your thoughts and feedback!
