1. Not Showing a QR Code
Forcing mobile users to copy a 42-character address is a conversion killer. Add a QR code. Wallet apps scan it in one tap.
2. No Countdown Timer
Without a visible timer, customers don't know the session expires. Add a prominent countdown starting from 20:00. Many users will rush to complete payment when they see 5 minutes left.
3. Asking for the Exact Amount to the Cent
Exchange withdrawals often have fees or rounding differences. Accept ±2% of the expected amount. Rejecting a $49.85 payment when you asked for $50.00 is infuriating.
4. No Mobile Wallet Deep Link
Add a "Open in Wallet" button for mobile. Format: trust://send?asset=c20000714_t...&address=0x...&amount=50. Trust Wallet, MetaMask, and Binance Wallet all support deep links.
5. Unclear Network Instructions
Many users accidentally send BEP-20 USDT on the wrong network. Prominently display: "Send on BNB Smart Chain (BEP-20) only." Add a warning about wrong-network sends.
6. No Copy-to-Clipboard Button
The raw address should be copyable with one click. Don't make users select text manually.
7. Hiding the Transaction Status
Show "Waiting for payment…" with a spinner. When the payment is detected, show "Payment received — confirming on blockchain…". Users want real-time feedback.
8. Sending to a New Address After Expiry Without Warning
If you renew the session, the new address is different. Warn the user clearly. Sending to the old address after renewal means they paid the wrong address.
9. No Support Link
Crypto is new to many users. A visible "Need help?" chat link or email reduces abandonment from confused customers.
10. Not Testing on Mobile
70%+ of crypto users access wallets on mobile. Test your entire checkout flow on iPhone and Android before launch.
