25 UX Mistakes Crypto Exchanges Still Make

Crypto exchange UI UX is FinTech UX with irreversible settlement. Most of the leaks below are not “crypto culture.” They are product mistakes SaaS teams already learned to stop making.

This list is for founders and product leads shipping an exchange, brokerage, or on-chain trading venue. For a full engagement, see Web3 Product Design and the Digital Assets & Web3 industry page.

Onboarding and trust

1. Connect Wallet as the first screen. Show the market, the fee model, and why this venue exists before asking for a signature.
2. No entity or jurisdiction in the footer. Users looking for a serious venue check this in the first minute.
3. Audit and proof-of-reserves links buried in a blog. Put them next to deposit CTAs.
4. KYC dumped as a PDF maze. Split identity steps. Explain what unlocks at each tier.
5. Support only via a Discord that looks unofficial. Serious money needs a named channel.

Wallet, network, and fees

6. Wrong-network errors with no recovery. Detect chain, offer a switch, do not blame the user.
7. Gas shown after confirm. Preview network cost before the signature.
8. Deposit addresses without a network label. USDT on the wrong chain is a support ticket and a lost user.
9. QR codes that do not include the chain. Mobile users will scan the wrong thing.
10. Memo / tag fields optional when they are required. Make them required and explained.

Trading ticket

11. Market vs limit with no plain-language difference. One sentence under the toggle.
12. Slippage hidden in a gear icon. Surface it when it will actually move the fill.
13. Order book density with no default “simple” mode. Most first trades should not require a depth chart.
14. PnL that changes colour meaning across screens. Green is profit everywhere or nowhere.
15. Leverage without a liquidation preview. Show the price that wipes the position before enable.

Transaction feedback

16. Pending, failed, and dropped look identical. Distinct states, distinct next actions.
17. No copy-able tx hash. Support cannot help if the user cannot paste an id.
18. Silent partial fills. Say what filled, what remains, and whether to cancel.
19. Withdrawal ETA as “soon.” Give a range and what delays it (network, review, limits).
20. Failed withdrawal with no reason. Insufficient gas, limit, or compliance — name it.

Mobile and accessibility

21. Desktop-only order books. First sessions start on a phone. Ship a usable mobile ticket.
22. Tiny satoshi / wei strings as the primary amount. Human units first, raw units in details.
23. Contrast that fails on OLED. This is a financial product. WCAG still applies.
24. Toasts that vanish before the user reads the hash. Persist critical confirmations.
25. No “cancel and stay” on scary dialogs. Unlimited approvals need a default-safe option.

What to do this week

Pick the first successful trade as the north-star task. Run a UX audit on connect → deposit → first order → withdrawal. Fix the three P0s that block that path.
