Our clients



cLabs is a member of the Alliance for Prosperity and part of the community working on Celo.

We are helping cLabs to secure the blockchain ecosystem by performing security assessments for following projects:

Rockaway Blockchain Fund

The largest European investment fund focused on investment into blockchain and digital assets, with a target value of $ 100 million.

We are happy to support RBF on their investment decisions by our technical due diligence process.

Marinade Finance

Liquid staking protocol built on Solana.

The audit scope was 4 engineering weeks, we co-audited with Kudelski Security and Nedodyme.

Marinade was presented as "The most trusted staking on Solana" on the Solana Breakpoint conference.

Community Gaming

Community Gaming’s platform creates a seamless experience for tournament organizers to host grassroots tournaments and for gamers to compete and instantly get paid when they win.

We have performed a quick 5 MDs review of Ethereum smart contracts.

The audit was not published.

Why Ackee Blockchain?

Our value lies in a strong technological background which allows us to
spread our know-how in blockchain further.

Strong member of Blockchain

Our team of blockchain engineers led by Josef Gattermayer, Ph.D., assistant professor at CTU, shares their expertise globally. Besides providing open-source solutions to the development community, we contribute to conferences like Devcon, where we also provided the official conference app.

Trusted by the Best

Assigned official development grants by three key blockchain foundations – Ethereum Foundation, Tezos Foundation and KIN Foundation.

Sharing knowledge


University lectures

Josef Gattermayer, Ph.D. is a speaker and co-autor of a new blockchain subject NIE-BLO at the Czech Technical University in Prague. Subject tutorials guided by Ackee Blockchain team are focused on Solidity development and auditing.


School of Solidity

We were missing a Solidity development and auditing course for the wide public so we decided to create our own.

We introduce to Ethereum tooling, Solidity fundamentals and security principles in 7 online lessons.

Successful participants are awarded by Ackee Blockchain Solidity Foundations certificate.


Solana tools

Solana ecosystem lacks a lot of tooling and that's why we decided to implement a Rust client.

Read more about the upcoming project here.


Opensource DevKits

Our mission to bring blockchain closer to developers is realised here. We made it possible to call Ethereum smart contracts directly from the Swift language. Since our open source release of the library and code generator, iOS developers can work with Ethereum smart contracts as with another SDK. Another contribution to the community was made with our PoC app using Tezos DevKit with step-by-step tutorials of how to use its TezosSwift library.

Executive team

With years of experience under our belt, we are ready for any challenge.
