Do you need a crypto website/app?

That can be a considerable challenge. Keeping wallets and crypto‑coins safe is no small feat. At Extenva we know it all. We make sure your crypto website/app keeps running smoothly, even when your platform becomes popular and needs larger servers for immediate trading.

The owner of Extenva started out with a self‑developed crypto‑coin. If you have complex questions or problems, we always find a solution.

Whether it’s NFTs, smart contracts or on‑chain data, we build systems that actually work. No unnecessary fluff or pricey promises.

We help you connect blockchain functions smartly to your website or app. This keeps the user experience smooth while the technology runs safely and scalably in the background.

We don’t just think about the code, we also consider the visual design. A good blockchain solution should also look sleek.

Crypto projects often attract a lot of traffic, which demands speed and stability. We optimise servers, caching and security so your platform is always ready, even under peak load.

We also keep everything safe: from APIs to transactions and user data. Everything is built according to the latest security standards so sensitive information never ends up exposed.

This lets you focus on your project while we make sure it runs like an automatic watch.

Low Carbon.

We build our websites in a way that is energy‑efficient.

Through efficient code and minimizing calculations we ensure that less electricity is needed to run the site. This way your company contributes to the environment without any extra effort on your part.
