Polygon has become the value layer. It's scaling with AggLayer, unifying liquidity, and powering apps with ultra-low fees. Two of its most ambitious ecosystem projects are Katana and Billions. @katana is a purpose-built DeFi chain reverse-engineered for AggLayer. Incubated by Polygon Labs and GSR, with infrastructure support from Conduit, it delivers what DeFi users and builders want most: deep liquidity and real yield. Katana unifies liquidity through VaultBridge and sequencer fees, with Sushi and Morpho as its core DeFi primitives. It’s the first AggLayer CDK chain to adopt the OP Stack, kicking off AggLayer’s multistack era. @billions_ntwk takes on the internet’s trust problem with a mobile-first proof-of-personhood network. Built on Privado ID’s ZK infrastructure and developed by veterans from Polygon, Disco, and Circom, it verifies humanity with just a passport and phone. Accessible and private, Billions ensures users control their data while scaling to billions of people worldwide. The first network for humans and AI, embedding reputation and trust into the internet of value. Backed by $30M from Polychain, Coinbase Ventures, Polygon, and more. Together, Katana and Billions show Polygon’s vision: scaling requires an ecosystem that unlocks real use cases for the next wave of users.
