MicrovestApp
Turns everyday card purchases into automated micro-investments, on web and mobile
About this project
MicrovestApp is a fintech investment product built around a simple idea executed carefully: turn everyday card purchases into automated micro-investments without asking users to think like traders. The platform rounds up daily transactions, invests the spare change into diversified digital asset portfolios, and syncs securely with connected bank accounts to keep balances accurate in real time. Onboarding runs through progressive KYC so new users aren't blocked by a wall of compliance forms before their first roundup, and the backend is built to handle high-volume micro-transactions with cost-efficient batching a detail that matters a lot when every transaction is worth cents, not dollars. Layered on top is Drippy Droppy, an AI assistant and insights panel that reads crypto market conditions in real time and surfaces personalized savings guidance when to lean into a roundup, when to hold instead of leaving users to guess. The result is a genuinely simple web and mobile path into small, recurring investing, with none of the manual portfolio management that usually comes with it.
Microvest Mobile App
The Microvest mobile app gives users a simple path from account setup to small recurring digital-asset investments. The mobile flow supports progressive onboarding, KYC collection, secure funding, BTC purchase screens, spare-change roundups, portfolio visibility, and transaction feedback so users can invest from everyday purchases without managing a complex trading interface.
- Spare-change roundups from everyday card purchases
- Secure bank and payment-method connection
- BTC and diversified digital-asset purchase flows
- Mobile-first KYC, portfolio tracking, and transaction status
Drippy Droppy
Drippy Droppy is MicrovestApp's built-in AI feature, part chatbot and part insights panel, that reads crypto market conditions and turns them into savings guidance a non-trader can actually act on. Instead of leaving users to interpret charts themselves, it analyzes market trends continuously and surfaces personalized recommendations when to lean into a roundup, when to sit tight directly in the app.
- Conversational AI assistant for savings and investment questions
- Always-on insights panel driven by live crypto market analysis
- Personalized guidance on when to increase or hold roundup contributions
- Market interpretation handled for the user, not left as a raw chart
Choosing a Digital Asset Custodian
Every roundup in MicrovestApp ends up as a real digital asset sitting in a real wallet, so the custody layer underneath it was not a decision to make lightly. We evaluated multiple institutional custody providers, including BitGo and Fireblocks, going back and forth directly with both on deposit and withdrawal flows, wallet architecture, and fee structure before settling on BitGo. Two things decided it: BitGo gave us more flexibility over how deposits and withdrawals actually move through the system, and its support for creating child (segregated) wallets under a single parent wallet came with zero fees which meant we could receive user payments directly into per-user child wallets, with everything rolling up cleanly to the parent wallet, without absorbing a per-wallet cost that would have made small, spare-change deposits uneconomical to custody.
- Evaluated BitGo and Fireblocks directly on deposit/withdrawal flexibility and wallet architecture
- Selected BitGo for greater control over deposit and withdrawal flows
- Zero-fee child (segregated) wallets under a single parent wallet
- Per-user child wallets receive funds directly, rolling up to the parent wallet without added cost
