Wallet Connection
The Flow
- Prompt: Don't ask to connect immediately. Show value first.
- Selection: Show supported wallets clearly. Highlight installed wallets.
- Connection: Show pending state. Handle rejection gracefully.
- Confirmation: Show connected address (truncated: 0x1234...5678). Show network.
- Persistence: Remember connection across sessions. Don't re-prompt on every visit.
Common Mistakes
- Showing 30 wallet options when 3-5 cover 95% of users
- No clear explanation of why connection is needed
- No way to disconnect or switch wallets
- Not handling network mismatches (user on L2, app expects mainnet)
Transaction UX
Before Transaction
- Show exactly what will happen in plain language
- Display estimated gas fees in both native token and USD
- Show total cost (amount + gas) prominently
- Warn about high gas conditions
- Allow simulation/preview where possible
During Transaction
- Show clear pending state with estimated time
- Provide transaction hash as a link to block explorer
- Allow user to continue using the app while waiting
- Handle stuck transactions gracefully
After Transaction
- Confirm success with specific details (not just "Transaction successful")
- Show what changed (balance before/after, NFT received, position updated)
- Provide receipt/summary they can reference later
Multichain
Network Switching
- Show current network clearly at all times
- Auto-detect when user is on wrong network
- Provide one-click network switching
- Show assets per network, not mixed together
Cross-Chain
- Make bridging feel like one action, even if it's multiple transactions
- Show estimated time for cross-chain operations
- Track progress across chains
Token Display
- Always show token symbol AND icon
- Display appropriate decimal places (2 for stablecoins, 4-6 for volatile tokens)
- Format large numbers (1.2M not 1,234,567.89)
- Show USD equivalent alongside token amounts
- Handle unknown tokens gracefully (don't just show the address)
Security UX
- Clear permission explanations for token approvals
- Warning UI for unlimited approvals
- Phishing protection (verify contract addresses)
- Scam token detection and warnings
- Clear revoke/disconnect flows
