Inspiration

Meeting people at hackathons can be awkward — we wanted to make it fun, rewarding, and on-chain.

What it does

Gamifies networking: complete quests, share photos, and earn SUI rewards for meeting new people.

How we built it

Built with Next.js, Sui SDK, Move contracts, and IPFS for storing photos. Integrated Slush Wallets for smooth sponsored transactions and future reward automation.

Challenges we ran into

Originally planned to use Walrus, but it required too many WAL tokens and the faucet was unreliable — we couldn’t upload even one image. Switched to IPFS for speed and reliability. Accomplishments we're proud of Deployed a working on-chain reward pool, integrated Slush Wallets for sponsor-backed payouts, and made every user activity verifiable on-chain.

What we learned

How to build with the Sui Move framework, use sponsored transactions, and design on-chain UX that feels like a normal social app.

What's next

for Icebreaker Enable full reward verification, let sponsors create dynamic quests, move to mainnet, and power networking at real hackathons with on-chain social proofs.

  --module escrow_pool \
  --function deposit_shared \
  --args 0x94bd6487e22a711507bd85144aca335e34996962065bbe9189c7aa7ac4c7447e <YOUR_COIN_OBJECT_ID> \
  --gas-budget 10000000

Option 2: Send SUI to the Pool Object

Send SUI coins to the pool object address using any Sui wallet
The pool will automatically accept and store them

🚀 Getting Started

Prerequisites

Node.js 18+
pnpm
Sui CLI (for deployment)

Setup

Clone and install:

git clone <repo>
cd icebreaker
pnpm install

Configure environment:

cp .env.example .env
# Add your sponsor wallet and pool IDs

Run the app:

pnpm dev

Visit http://localhost:3000 and start earning SUI!

🎯 How Rewards Work

User uploads a photo/participates in activity
App calls the escrow pool smart contract
Contract withdraws 0.003 SUI from the pool
SUI is transferred to the user's wallet
Pool balance updates in real-time
Everyone can see how much SUI is left

🔒 Security

Pool is password-protected
Only authorized withdrawals via sponsor wallet
All transactions on-chain and transparent
No private keys stored in the app

🤝 Built For

This project was built for a hackathon as a proof of concept for:

Gamified social networking
Automated micro-rewards via smart contracts
Transparent reward distribution
On-chain pool management
