Hey HN, I'm Alessandro, founder of unflat.finance. We're an Italian startup building a stablecoin yield app for everyday Europeans people who have never touched a wallet, don't know what Morpho is, and have no interest in learning. What we do today: Users deposit euros via cooinbase pay. We convert to USDC, split their deposit across multiple isolated Morpho vaults on Base chain (each with different collateral types and borrowers pledging 150-200% of what they receive), and they earn 4-7% APY. They see one number: their balance growing daily. No wallet, no gas fees, no tokens. We have apps built for both iOS and Android, currently in beta. The market context: This category is exploding in the US. Axal (a16z CSX, $2.5M), Nook (Coinbase Ventures, $2.5M, ~7.6% avg APY, built by ex-Coinbase/Uber team), YieldClub ($2.5M), and Aave itself launched a consumer savings app with up to 9% APY and $1M deposit protection. They're all live or in waitlist. They all run on the same proven infrastructure (Morpho has had $8.5B in peak deposits, 25+ audits, backed by $69M from a16z and Coinbase Ventures, used by Société Générale). But they're all US-first. ACH, Plaid, Apple Pay, USD-denominated. Europe 350M+ banking customers sitting at near-zero rates — has no equivalent. In the US you can get 4-5% at Marcus or Wealthfront. In Europe, most banks pay 0.5% or less. The yield gap here is wider, and nobody is serving it. That's our bet. We're also working on EURc (Circle's euro stablecoin) integration so the entire flow stays euro-denominated — no FX exposure. That's something no US competitor can replicate. What we want to build next: An AI agent that automates portfolio allocation based on each user's risk profile. You answer a few questions about risk tolerance, time horizon, goals the agent handles vault selection, rebalancing, entry/exit across DeFi strategies. Think Wealthfront/Betterment for crypto, not another trading bot. The multi-vault architecture on Morpho makes this natural: different risk profiles map to different vault compositions. Where I need help:

Go-to-market for non-crypto users in Europe: Our target is the person with €10-50K in a savings account earning nothing, not crypto Twitter degens. Every crypto marketing channel attracts the wrong audience. We're running a waitlist with tiered bonuses (+2% APY for first 500 users, referral bonuses), but how do you actually reach normal savers? Has anyone cracked fintech distribution in Europe without burning cash on Meta/Google ads (which are restricted for crypto anyway)? Driving traffic to the site: SEO/GEO is slow, content marketing takes months to compound, paid ads for crypto are a minefield. What's actually moved the needle for early-stage fintech in Europe? We're bootstrapped, so capital-efficient channels matter. Trust for non-crypto users: We lead with radical transparency — every user gets a public on-chain link showing every deposit, earning, and withdrawal. We put risk disclaimers front and center ("this is not a bank account, never deposit what you can't afford to lose"). But is that enough? What trust signals actually convert skeptical Europeans?

The stablecoin savings app category is being defined right now. YC literally listed "stablecoin financial services" in their latest Requests for Startups. We think Europe is the bigger opportunity — the yield gap is wider and nobody's building here yet. Would love to hear from anyone who's built in this space.
