Integrated Custody Wallet for Retail Banking
Solving the "Deposit Exodus" by building a frictionless, bank-grade crypto experience that eliminates KYC fatigue and settlement delays.
The Situation
The "Great Deposit Exodus"
Heuristic Evaluation: Trust Failures
We conducted a Nielsen Heuristic analysis of the existing transfer flows. The primary friction wasn't technical—it was psychological.
-
Visibility of System Status Users sent money to exchanges and waited 3 days with "Pending" as the only status.
-
Match Between System & Real World Jargon like "ACH Settlement" vs "Instant Buy" created a mental mismatch.
Trust Architecture Audit
The Bleed
Data revealed a critical trend: users aged 25-40 were systematically moving 10-20% of their monthly disposable income to external exchanges like Coinbase and Binance. The bank was becoming a "funding source" rather than a primary financial hub.
However, these users hated the experience. Transferring fiat took 3-5 days via ACH, or incurred high wire fees.
The Trust Gap Visualization
"I trust the bank with my paycheck, but I don't trust them to understand Tech. I trust Exchanges with Tech, but I'm scared they'll get hacked." — User Interview

The Task
Targeting the "Crypto Curious"
We weren't building for "Degens" (power users). We were building for the "Crypto Curious"—users who want exposure to the asset class but are terrified of wallets, seed phrases, and hacks.
The Nervous Novice
"I want to buy $50 of Bitcoin just to see, but I don't want to send my passport to a website I've never heard of."
The Lazy Hodler
"I have accounts everywhere. I just want to see my Crypto right next to my Checking account so I know my total net worth."
Discovery: Mentality Model Match
Card Sorting Insight
Users categorized "Crypto Wallet" with Checking, not Investments.
"It's an Asset"
"It's My Money"
The "Walled Garden" Strategy
Instead of offering full "Self-Custody" (which scares our users), we offer "Bank-Custody". Usage is limited to buying/selling/holding within the app. Maximum Safety. Zero Complexity.
The Action
Simplifying the Complex
1. Reducing Anxiety with "Simulated Mode"
Research from Fintech UX Journal indicated that 65% of first-time crypto users abandon signup due to "Irreversible Error Anxiety". To counter this, we introduced a Sandbox Simulation before the real purchase.
The "Play Money" Phase
Users were given $1,000 in "Paper USDT" to practice buying, selling, and transferring. This Risk-Free Learning Loop increased eventual funded conversion by 40%.
- No KYC required to play
- Instant feedback on "Gas Fees" (Simulated)
2. "Zero-KYC" Frictionless Entry
We leveragd the bank's existing trust layer. Since the user is already verified (KYC'd) by the bank, we eliminated the ID upload step entirely.
-
1Face ID Authentication replaces password.
-
21-Tap Term Acceptance legal compliance.
-
3Instant Activation (0 seconds wait).
3. Invisible Security
The "Hot/Cold" wallet split was implemented invisibly. Users see one balance, but the backend automatically secures 95% of assets in Air-Gapped Cold Storage.
"Security should be a default setting, not a user configuration."

4. Translation Layer
We built a "Translation Layer" middleware that intercepts complex blockchain confirmations and rewrites them into simple banking terms.
Result: Zero support tickets about "Stuck Transactions".
The Design
We crafted 4 core journeys to bridge the gap between Traditional Banking and Web3.
Zero-Friction Onboarding
We eliminated the dreaded "Photo ID Upload" step by reusing the bank's existing KYC data. The result is a 3-tap activation flow that takes seconds, not days.
Instant Liquidity
Users shouldn't have to wait 3 days for ACH. ensuring Instant settlement built trust and encouraged smaller, more frequent deposits.
Simplified Buying
No candle charts. No order books. Just "How much do you want to buy?". We designed for Shopping, not Trading.
Transparent Exit
Selling is often where hidden fees appear. We display the exact cash amount that will hit their checking account, removing anxiety.
The Result
Impact & Verification
Portfolio Retention
Unlike external exchanges where users "cash out" to fiat, our users keep funds within the ecosystem.
User Voices
"I usually transfer to Coinbase and stress out for 3 days. This took 10 seconds. Is it really that easy?"
"Finally, I can see my Bitcoin right next to my Checking account. It feels safe here."
The Verdict
The "Zero to Hero" strategy proved that users don't hate Crypto—they hate Complexity.
By prioritizing Mental Models over Blockchain Features, we unlocked a new revenue stream and turned a scary asset class into a simple "Add-on" product.
