Coinbase product sense: crypto banking built around social features

Design a crypto banking product for Coinbase in which social features are central rather than an add-on. Walk through who it is for, which problems it solves, what you would launch first and how you would measure it. ```hint Pin down the social job Before listing features, decide what people would actually do with money together, and why doing it in crypto through Coinbase beats the apps they already use for it. ``` ### Clarifying Questions - Does "social" mean money moving between people (paying friends, splitting costs, shared balances), sharing investing activity and ideas, or both? - Is this a standalone app or a set of features inside the existing Coinbase app, and can it start from Coinbase's existing verified customers? - Which market should launch first, given that money transmission, deposit and investment rules differ by country? - Should balances be limited to crypto and stablecoins, or also include ordinary dollar accounts held through a banking partner? ### What a Strong Answer Covers - A stated interpretation of "social" and "bank", tied to a goal that matters to Coinbase - One prioritized user segment, with pain points specific to holding and moving crypto with other people - A prioritized feature set with a clear first release and a plan for getting the network started - Trust, safety and compliance: irreversible transfers, scams, privacy of balances and activity, licensing - A north-star metric with guardrails that would catch unhealthy growth ### Follow-up Questions - A feed showing what friends buy could push people into hype-driven trades and pump-and-dump schemes. Would you build one, and how would you limit the harm? - A user sends stablecoins to the wrong contact. What does the product do, and what does it promise up front? - How would the product change in a market where people hold dollar stablecoins mainly to protect their savings from inflation?
