Hey pioneer
So you are looking for a solidity developer?
The fact you're even searching puts you in a very small, innovative group. That's cool!
Let's talk numbers👇
Is the expected valuation of blockchain tech by 2026
Is the expected crypto growth between 2022 - 2030

Surely you can't mess this u.... Oh wait 🤦♀️
Although the crypto space is incredibly exciting, launching a product doesn't at all mean it's any easier...sorry.
The nature of a smart contract gives you one shot to build a great product. Let's explain.

Stop thinking Web2 🙄
For the last 20 years, innovators like you have been able to come up with an idea, approach a contractor on something like Fiver and get them to build you a basic MVP. From there you were able to test what your customers wanted, improve security & infrastructure as you went, and scaled on your terms.
But with a smart contract, you have to think smarter. You need to nail security, infrastructure, gas fees and scalability before you go live. And if that doesn't seem like a lot, you also need to think through an exciting offering that can engage a community, attract users, retain users and make user adoption simple, all before going live.
We're not your typical developer from Fiver, based in Bristol, we’re full-service solidity developers that can turn your idea into a scalable dApp that will grow your business.

Your expertise. Our coding
You know your industry, we know Blockchain development. Before we will build you an app, we need to listen to your expertise, understand your industry and apply it to the world of blockchain app development.
Community builders
Imagine having your feedback and suggestions being heard and acknowledged right away—this is an excellent example of great customer service that translates to a great experience. We will help you build your own community so you can maximise your growth.
UX and UI
Long-term end-user adoption of any application is heavily determined by the UX and UI of that application. However, currently, the UX and UI in crypto products are generally poor. We'll help you develop an app that is easy for the end-user helping you to grow.
Blockchain development
We will design, build and distribute a mobile app and wallet connected to the blockchain. Allowing users to either pay for or be rewarded for their actions with cryptocurrency. We also manage the security keeping the transactions safe.
