The Hackathon was hands-down my favourite part of @ParisBlockWeek. An amazing space to meet new builders on #XRPL, team up with strangers, and actually bring ideas to life in 36 hours. Massive shout out to the @xrpl_commons team, it was incredibly well organised and exceeded every expectation. 170 builders • 40 submissions. 🔥 #HackTheBlock #PBW26
This year, @ParisBlockchainWeek 2026 had only one hackathon and it was on XRPL. Students, founders, and devs from across Europe, all in the same room, building real-world solutions on a fast, efficient, proven, compliant-ready chain. This is what building on the XRP Ledger with XRPL Commons looks like. See you at the next one.

Great seeing @Mastercard’s SVP of Global Partnerships (Digital Assets), Christian Rau, in the crowd, and locked in on @XRPL_Commons#HackTheBlock winner presentations during Day 2 of #PBW26. 👀 Momentum is definitely building in the #XRPCommunity. 🌊 #XRP #Crypto
Mastercard 🤝 XRP Ledger. @Odelia_Torteman (XRPL Commons) and Christian Rau (@Mastercard) discuss bringing direct settlement in RLUSD to the Mastercard network. The bridge between TradFi and Web3 just got a whole lot stronger.

36 hours ago… most of these people were strangers. Today? They built real products on the #XRP Ledger thanks to @xrpl_commons and incredible mentors. Payments. AI. Infrastructure. Real utility. From sleepless nights to final pitches and winners announced — this is what building actually looks like. 🚂 Strangers → teammates → friends. The future isn’t coming. It’s being built. #HackTheBlock #PBW26 #XRPCommunity

CorLens is 2 things: Corridor Atlas - the first public map of every fiat-to-fiat corridor on XRPL with real-time liquidity and health status Safe Path Agent - an AI agent that finds the safest route for any currency pair and flags on-chain risks nobody else catches, thanks to inner tools like our entity audit Second place on the Data Visualisation track.

Two 42 teams. Two prizes at #HackTheBlock 2026 HerVoice by Huilin @guo_lin31034 (42 Paris), Allegra & Rebecca won 1K on the Impact Finance track The problem: thousands of women travel to France each year for reproductive healthcare. Funding exists but clinics can't verify it before providing care HerVoice bridges funders and clinics with a trustless payment flow on @xrpl_commons , funds are locked in escrow and released only when the patient arrives. No identity stored. Full transparency for funders. Zero risk for clinics. XRP402 also won 1K on the Zero to User track, dedicated post coming soon Proud of our builders @ParisBlockWeek @KRYPTOSPHERE_ HerVoice: github.com/allegramelli-tech… #XRPL #ParisBlockchainWeek
