Neobanks are emerging as pivotal players in the crypto landscape, driven by the 'fat app' theory, which envisions fintech applications evolving into comprehensive financial platforms. These platforms integrate deposits, yield, and distribution channels, operating on thin unit economics like interchange fees and net interest margins. This approach mirrors strategies used by public blockchains such as SUI and Monad, focusing on capturing user attention and behavior. The growth model for neobanks involves a flywheel of customer acquisition, retention, monetization, and trust. Apps like Revolut and Monzo exemplify this by leveraging their large user bases to control significant financial float, reducing switching costs by centralizing financial activities, and expanding through cross-selling. The shift in capital flows from volatile token speculation to stable yield platforms and privacy-focused payment solutions is also highlighted. Revenue streams for these neobanks include transaction fees, yield on stable deposits, and credit markets, with 20 promising projects identified as poised to benefit from this trend.
