## Description

Sustainable liquidity on L2s is still unsolved. But Katana and GSR offer different pieces of the puzzle. Katana outlines its vertically integrated approach: stacking yield, aligning core apps, and owning protocol liquidity. GSR brings the market maker’s perspective, emphasizing incentives, institutional requirements, and capital efficiency. The discussion covers real yield, fragmentation challenges, and why opinionated chains may outcompete general-purpose networks. It's a sharp dive into what’s broken in L2 DeFi and what might fix it.

Speakers:
Marc Boiron, CEO, Polygon/Katana
Jakob Palmstierna, President, GSR

Moderator: Ivan Fartunov , Ecosystem Lead, Aragon
