Curious how widespread the killer app dependency problem is after seeing this.
Gas data across chains in the last 30D:
→ Polygon: Polymarket 84%
→ Solana: Pump fun ~65%
→ Ethereum / Base / Arbitrum: no single app above 25%
This concentration is essentially the appchain thesis in motion, dominant apps eventually ask why they aren't capturing more of the value themselves.
DeFi has been the exception. Liquidity networks are hard to fork and even harder to migrate, that's been the main argument against apps leaving for their own chains (HyperLiquid being the notable exception, built its own chain, kept liquidity and proved the moat isn't unbreakable).
The question isn't if dominant apps leave for their own chains. It's when they leave and which chains are building a resilient enough ecosystem to survive it.
The real moat isn't liquidity alone, it's liquidity composability, making the cost of leaving higher than the benefit of owning the chain.
