Shardeum HackSprint: 200+ Builders, 110 Projects in 3 Days

The Setup

HackSprint was a fast-paced hackathon focused on building real-world utility applications on Shardeum, with strong participation from students at REVA University, Bengaluru.

Over 3 days (March 23–25):

• 200+ participants joined
• 110 projects were submitted
• 100 participation NFTs were minted

Participants ranged from experienced developers to first-time builders, focused on shipping usable, on-chain products.

Why This Was the Right Time to Build

We’re at a point where builders have more access than ever before to tools, communities, and infrastructure.

The timing couldn’t be better:

• Increasing adoption of emerging technologies like AI
• Growing demand for real-world utility
• Easier access to powerful dev tools and infra

HackSprint tapped into this momentum challenging builders to create solutions that don’t just exist, but actually matter.

How It Ran

1. Onboarding (1 hour)

We kicked things off with a focused onboarding session aligning everyone on the problem space, tooling, and expectations. This ensured even newcomers could get up to speed quickly and start building with confidence.

2. Rules and Team Formation

Clarity was key:

• Defined judging criteria (innovation, usability, scalability)
• Clear rules to keep things fair and competitive
• Teams formed around ideas, not just existing circles

This phase set the tone: collaborative + driven.

3. Six-Hour Build Sprint

This was where things got real.

For six hours straight, the room turned into a live product lab:

• Teams built not just features but end-to-end workflows with complete user journeys powered by smart contracts
• A set of teams tackled job and task coordination systems with on-chain actions like posting, claiming, assigning, and completing work
• Another set focused on tracking systems leveraging on-chain data to make actions visible, traceable, and transparent in real-time
• Few others explored creator-first platforms enabling monetization, tipping, NFTs, and ownership primitives
• Others designed multi-role systems with different experiences for admins, contributors, and users interacting through wallets

This wasn’t just code, it was product thinking under pressure, built on-chain.

4. Demo Session (2 hours)

Each team:

• Presented their product
• Explained their approach
• Received live feedback

The range of ideas covered both developer tooling and user-facing applications.

5. Polish Window (48-Hours)

After demos, teams had 48 hours to:

• Improve UX
• Fix issues
• Refine their pitch

Submissions moved closer to usable products, not just prototypes.

What Actually Shipped

Across 110 projects, clear patterns emerged:

• Functional dApps with full workflows including – landing pages → real flows from wallet connect → transaction → outcome
• Task and workflow systems solving real coordination problems using smart contracts
• On-chain tracking and visibility tools making invisible processes transparent
• Creator and community tools built around tokens, NFTs, and ownership
• Role-based systems where different users interacted within the same product via wallets and permissions

The key shift:
Using frontier tools, builders focused less on technology with a great level of abstraction and more on how users interact, coordinate, and transact on-chain.

Participants also minted 100 NFTs as proof of participation.

Top 3 Projects

1. ProofMarket

A prediction market where experts stake tokens on outcomes.
Reputation is built on-chain, and incorrect predictions have direct financial consequences.
Users can copy-stake based on trust.

2. Credicast (Team: Stray Care)

A prediction platform with a focus on credibility tracking.
Users can create and participate in forecasts with transparent, trustless execution using smart contracts

3. Pariprashna AI

An AI-based learning assistant focused on Sanskrit and Vedas.
Uses a retrieval-based (RAG) system to deliver accurate meanings, translations, and context.

Beyond the Event: Ripple Effects

The impact extended far beyond the hackathon itself.

Participants took to social platforms to share:

• Their builds
• Learnings and struggles
• New connections and collaborations

The common theme?
“This wasn’t just a hackathon, it was a builder experience.”

From first-time hackers gaining confidence to experienced devs discovering new ideas, HackSprint created momentum that will continue well beyond these 3 days.

What Made It Work

Three factors stood out:

• Builders helping each other
• Ideas evolving in real-time
• A focus on learning over winning

This balance of culture + code is what turns hackathons into ecosystems.

Closing Note

None of this would have been possible without:

• The builders who showed up and gave it their all
• The organizers who made it seamless
• The community that amplified the experience

Every contribution big or small helped shape what Shardeum’s HackSprint became.

Join Us in This Building Journey

If there’s one takeaway from the HackSprint, it’s this:

The future isn’t just imagined, it’s built.

And we’re just getting started.

Whether you’re a developer, designer, or just curious:

• Start with a simple idea
• Focus on execution
• Ship something usable

Because the next breakthrough?
It might just come from you.
