About
Paris Blockchain Week hackathon powered by XRP Ledger
A 36-hour engineering sprint. Real challenges. Real stakes.
Hack the Block brings together the builders shaping the next generation of digital asset infrastructure, in the heart of Paris, during Paris Blockchain Week.
Teams tackle problems that matter: moving real value on-chain, putting blockchain at the service of social and environmental impact, pushing the technical limits of the protocol, and surprising everyone with what nobody saw coming.
Projects are judged on technical rigor and product relevance, not hype.
Builders regularly walk away with job offers, funding conversations, or pilot integrations.
Themed tracks, special prizes for the most innovative, the most visually stunning, the most unexpected projects, and for whoever drives the most real users before time runs out.
Teams don't just compete. They get discovered.

XRPL settles value in 4 seconds for a fraction of a cent. Leverage XRPL core technologies like the super DEX, issued assets, NFTS, micropayments, or recent implementations of the X402 protocol for agentic transactions to design projects that powers real users, real businesses, and real flows of value.
We will reward projects that drive sustainable TVL, recurring transaction volume, and measurable ecosystem growth on the XRP Ledger. Whether it’s payments, real‑world assets, or institutional DeFi, we’re looking for teams who can show clear product market fit and a credible path from prototype to production impact.
