Stratis Build Hackathon

With over 500 participants and many exciting submissions, the Stratis Build Hackathon has come to a close, and we’re ready to announce our prize winners. This hackathon, the third launched by Stratis, was full of dynamic new talent and creative uses of blockchain technology. Stratis is committed above all to uncovering new ways in which blockchain can streamline and simplify business processes as well as adding value to the broader community.

Just like previous Stratis hackathons, we expect some of our winning entries to progress into fully fledged products and projects in the future. Learn more about the winning innovations below.

Grand Prize Winner – Silver: Smart contract static analyzer and formal verifier

Allister Beharry has been awarded first prize for his excellent security-focused Smart Contract tooling. As described by Allister

Silver is a static analyzer and formal verifier for Stratis smart contracts. Silver works both at the source code level and the bytecode level to provide knowledge about smart contract code and potential vulnerabilities and provide logical guarantees about smart contract code behavior before it runs.

Rowan de Haas, Stratis’ lead Smart Contract architect, was particularly impressed with this submission and commented

Silver is a truly impressive hackathon submission. It is a powerful tool that substantially contributes to the Stratis smart contract ecosystem by improving contract safety and developer workflow.

Second Place Winner – Group Knowledge Builder

The Group Knowledge Builder demonstrated a great use of Smart Contracts and IPFS to manage the decentralized storage of data; additionally, our judges liked the tokenomics introduced through participation.

A demo of the application can be seen on YouTube:

Third Place Winner – RingLetBox

DeFi has been a great use case of Blockchain technology. It has driven a growth in cryptocurrency adoption and utilization in recent years, evidenced by hugely popular platforms such as Maker, Curve and Aave, to name a few. RingLetBox, as described by its creator, Mark Erwin Villariña

RingLetBox is a Token Creation, Vesting, and Locking Platform. RingLetBox aims to protects every Cryptocurrency community from rug pulls and traitorous advisors.

It’s great to see submissions relating to DeFi and protecting new users in the space.

Fourth Place Winner – Stratis Gallery

Non-Fungible Tokens (NFTs) have become increasingly popular in recent years, with new platforms and marketplaces available on a near-weekly basis. One area of particular interest, both internally at Stratis and within Stratis SDA-backed project, Polycarbon Games, is the use of AR and VR to provide immersive and breathtaking experiences.

Yosun Chang shared this vision and developed a virtual gallery using Stratis’ Unity SDK, enabling users to navigate within a VR World and view NFTs.

A demonstration can be seen on YouTube:

Fifth Place Winner – NFT Exchange

Jeffrey Lewis submitted a brilliant NFT Exchange/Swapping solution, enabling NFT holders to safely and securely swap their NFTs for other popular items. The solution enables users to make offers and allows sellers to highlight what items they would want in exchange to optimize the user experience.

The ability to use the blockchain and Smart Contracts for escrow services has driven adoption by providing a sense of security, particularly when trading or exchanging large sums of value. The employment of Smart Contracts on a genuinely decentralized blockchain enables users to trust that funds held within escrow are managed in a safe, secure, and most importantly, decentralized manner.



The Stratis Build Hackathon was launched to give developers the opportunity to create new and inspired solutions on the Stratis Platform. With more and more creators building smart contracts on the Cirrus Sidechain, we look forward to seeing the grand prize winner, Silver, contribute to the well considered development of Stratis smart contracts.

With last month marking the launch of Stratis’ commisionless NFT marketplace, Stratisphere, it was also great to see two of the winning entries focused on delivering new NFT capabilities for the Stratis community, including both a gallery and an NFT swapping solution.

We thank all the participants for taking the time to develop some truly innovative solutions for the Stratis Build Hackathon and, of course, we extend our congratulations to the prize winners!
