Re{define} Hackathon

Re{define} Hackathon is a hackathon focused on two core narratives: Privacy and Bitcoin on Starknet.

We're building tools and applications that combine privacy-preserving technology with Bitcoin integration. From encrypted compute to atomic swaps, from zero-knowledge proofs to trust-minimized bridges, we want to see what builders create when they focus on what matters.

Why now?

• Privacy is the institutional priority for 2026
• Starknet is the Bitcoin DeFi Layer with quantum-safe ZK tech
• Starknet is doubling down on privacy and Bitcoin infrastructure, this is the moment to build

Timeline
