How we workEngagement Model

Hack-a-Chain works with Closed and Customized Scope Projects. That means that you’ll hire us to work at your idea (not a pre-engineered product) and the project will have a beginning and an end. But don’t worry about maintenance! The thing about blockchain projects is that the Smart Contracts are immutable, so you can’t make any changes at the back-end.

That’s why we are specialized in conducting as much test as it’s needed to make sure it works perfectly before we deploy it. You’ll mostly make changes at the front-end to keep improving user experience, and we’ll help you all the way throw the process of finding the right partners.

When you decide to improve your back-end, it’s time to create a Version 2 of your project, and we’ll be completely available to do that!

Build your project

Work experience with all kinds of projects in the crypto world.



Kangaroo Coin Flip is a game inside Near Protocol. The story behind this project is that our clients, Classy Kangaroos, were late at their calendar to deliver the project to the community. They had only two weeks until the deadline, and we all know that keeping up with your roadmap is a very important thing to keep the confidence on your project. The problem is that the devs they had hired couldn’t keep the necessary pace. That’s when we met them and said we would work day and night so that they could keep their promise to the community. No sooner said than done! After 2 weeks, we had fully developed the smart contract logic, containing a special profit split feature between Classy Kangaroo NFT holders, deployed the contract and, besides that, helped the front-end team so that the project could be delivered on time! The result, of course, was awesome: the best coin flip game inside Near Protocol – and it’s not us saying that, but the whole community! You can see and play the game here!

What our customers say

David Leer
Hack-a-Chain stepped up and took over development of Kangaroo Coin Flip when we needed help the most. Quickly they built out the KCF backend and fully integrated the existing front end. Comments from our auditors: 'without a doubt the best contract we've audited so far'.

About us

Hack-a-Chain was created in 2022, by 2 brazilian entrepreneurs that noticed a lack of professionals to help entrepreneurs developing high-quality projects for Web 3.0

  • They decided to create a software development company committed to create long time value projects along with visionary entrepreneurs.
  • Hack-a-Chain values security and quality above everything else.
  • Hack-a-Chain has the purpose to build the future, one block at a time.

We know that there is a lot of speculation around crypto and many skeptics think it has no real future. But the truth is crypto, blockchain and web3 in general are already changing the world and good projects will thrive in the long run. We want to help you build the blockchain projects of the future.

We aim to build long term partnerships, construct high-quality projects and we do believe in the projects we are working on.Let's go together?
