The European Web3 community showcased its strength and ambition at the Warsaw Demo Day, the final event of the Build Station Warsaw accelerator. More than 200 developers and founders from across Europe presented over 30 on-chain projects built during an intensive ten-day program focused on blockchain, AI, and automation.
The event began with a panel discussion titled “Stablecoins: Opportunities and Challenges”, featuring Antonina Karwasińska (Bank Pekao S.A.), Łukasz Wiśniewski (PKO Bank Polski), and Krzysztof Piech (Lazarski University). The speakers examined how traditional finance is adapting to digital assets and how stablecoins are helping bridge Web2 and Web3 ecosystems.
After the discussion, teams took the stage for three-minute pitches followed by a short Q&A with the judging panel. According to the organizers, the jury highlighted the high technical execution, practical value, and innovative design seen across the cohort. Still, only four projects claimed top honors:
🏆 Winners
- Alyra — Grant recipient from Incrypted
- TRUSTBYTES — 1st place in the Mastercard Track
- Pool Keeper — 2nd place in the Mastercard Track
- Sentience — 3rd place in the Mastercard Track
What the Winning Teams Are Building
Alyra introduced a framework that allows any application to integrate multichain swaps and bridges via a single API or SDK. By unifying liquidity and connectivity across networks, the solution aims to make interoperability simpler, transparent, and secure for developers.
TRUSTBYTES showcased a smart treasury management platform for institutional wallets. It integrates analytics, liquidity tools, and automation for asset management across on-chain and off-chain markets, effectively linking traditional finance with blockchain economies.
Pool Keeper, built on Solana, enables users to analyze historical APR, receive AI-powered performance insights, and rebalance DEX liquidity positions in one click. The platform seeks to streamline DeFi portfolio optimization through actionable data and automation.
Sentience presented an AI decision-support system that filters information noise and helps both people and autonomous systems make context-aware, efficient decisions. The project highlights how intelligent automation can improve accuracy in complex environments.
Organizers emphasized that Warsaw Demo Day marks not an endpoint, but a launchpad for further growth. Many participating teams are now preparing to continue development and present globally at the Colosseum Cypherpunk Hackathon.
The core message of the event was clear:
The European Web3 ecosystem is active, ambitious, and accelerating.
Open innovation is already happening — and it’s happening on-chain.
