Stellar x Polkadot HackerHouse BLR
Stellar x Polkadot HackerHouse BLR 🚀
Cross-Ecosystem Innovation Unlocked
🎯 The Opportunity
The future of blockchain isn't siloed. It's interconnected.
Stellar x Polkadot HackerHouse BLR brings together two of the most ambitious ecosystems in crypto; Stellar's lightning-fast, cost-effective smart contract platform (Soroban) and Polkadot's revolutionary interoperability architecture (Relay Chain + Parachains)-for an intensive 2.5-day building sprint where serious developers create the cross-chain applications of tomorrow.
This isn't another generic hackathon. This is a focused ecosystem convergence where you'll have direct access to core teams from Stellar India, Edgetributors, and ArQ (MontaQ Labs), working on real-world problems that bridge ecosystems.
💡 Why This Hackathon is Different
⚡ Real Cross-Ecosystem Focus
Most hackathons pick one chain. We're forcing you to think bigger.
Stellar: 3-5 second finality, sub-cent transaction fees, native asset tokenization, and Soroban's Rust-based smart contracts
Polkadot: Shared security, parallel processing, cross-chain message passing (XCM), and parachains as customizable application-specific blockchains
Your challenge: Build something that meaningfully leverages both ecosystems.
Whether it's a cross-chain DeFi protocol, tokenized real-world assets, a payment solution, or a novel interoperability primitive; we want to see you push boundaries.
🎁 Prize Pool: ₹50,000 INR
1st Place: ₹15,000
2nd Place: ₹10,000
3rd Place: ₹5,000
Participation Prizes: ₹20,000 split among all valid submissions
Every project that ships gets rewarded.
🧑💻 Mentorship From the Best
Direct access to judges and mentors from:
Stellar India (building the future of decentralized finance infrastructure)
Edgetributors/ArQ (MontaQ Labs) (Polkadot ecosystem educators)
These aren't random advisors, they're the builders shaping these ecosystems. They'll review your code, challenge your assumptions, and connect you with the right people.
