APP CHAINS GAIN TRACTION, FACE NETWORK INTEGRATION CHALLENGES\n\nApp chains are rising as top applications seek dedicated infrastructure. PolyMarket and Hyperliquid are building their own chains to control user experience, reduce costs, and capture more value at scale.\n\nPublic chains work early on, but congestion, volatile fees, and slow confirmations limit mature apps. Leading projects now treat the chain as part of the product itself.\n\nThe real challenge is not launching an app chain but making it functional. New chains face cold starts, fragmented liquidity, and weak ecosystem links. Success requires strong network integration from day one and built-in cross-chain connectivity. The value of app chains comes from how well they plug into the broader network, not just from existing as standalone chains.
