App Layer: Web3 Bazaars
summary
Three apps describe concrete migrations and results: Audius moves large parts of its stack to Solana to handle 450k+ tx/day and reports 14x user growth after the switch; Chingari converts a Web2 user base into NFT-backed videos and an in-app economy using the GAR token, with ~30 million monthly users but only ~1–2% crypto-native so onboarding remains a challenge; Kin abandons Stellar for subsecond UX, migrating wallets and exposing blockchain via the Agora API to hide complexity for apps.
