🤖 Auto Review Issue: Missing useEffect dependency causes exhaustive-deps warning
Severity: MEDIUM
Category: code_quality
Tool: Claude Auto Review
Context:
- Pattern: useEffect at line 50-63 has empty dependency array but references
fetchWalletsfunction - Risk: Effect won't re-run if
fetchWalletsreference changes, potentially causing stale closures - Impact: Could lead to runtime errors or unexpected behavior if function reference updates
- Trigger: When component remounts or fetchWallets reference changes
Recommendation: Add fetchWallets to dependency array:
useEffect(() => {
const loadWallets = async () => {
try {
setFetchError(null)
await fetchWallets?.()
} catch (err) {
setFetchError('Failed to load wallets')
console.error('Wallet fetch error:', err)
}
}
loadWallets()
}, [fetchWallets])| const [fetchError, setFetchError] = useState<string | null>(null) | ||
|
|

| const [searchQuery, setSearchQuery] = useState('') | ||

🤖 Auto Review Issue: Missing cleanup for debounce timer
Severity: LOW
Category: code_quality
Tool: Claude Auto Review
Context:
- Pattern: Debounce timer set at line 35 but no cleanup when component unmounts
- Risk: Memory leak if component unmounts while timer is pending
- Impact: setTimeout callback could run on unmounted component, attempting state updates
- Trigger: User navigates away from AllWalletsView before 500ms debounce completes
Recommendation: Add cleanup in useEffect:
useEffect(() => {
return () => {
if (debounceTimerRef.current) {
clearTimeout(debounceTimerRef.current)
}
}
}, [])| } | ||

🤖 Auto Review Issue: Missing error handling for async wallet connection
Severity: MEDIUM
Category: code_quality
Tool: Claude Auto Review
Context:
- Pattern:
handleSignMsgat line 53 is async but lacks try-catch block - Risk: Unhandled promise rejection if
signMessageAsyncfails (user rejects, network error) - Impact: Uncaught errors show in console, poor UX with no user feedback on failure
- Trigger: User rejects signature request in wallet or network issues occur
Recommendation: Add error handling:
const handleSignMsg = async () => {
try {
const msg = "Hello Reown AppKit!"
const sig = await signMessageAsync({ message: msg, account: address as Address })
sendSignMsg(sig)
} catch (err) {
console.error('Error signing message:', err)
// Optionally show user-facing error message

🤖 Auto Review Issue: Same issues in React example
Severity: MEDIUM
Category: code_quality
Tool: Claude Auto Review
Context:
- Pattern: React example has identical missing useEffect dependency (line 50-61) and missing debounce cleanup as Next.js example
- Risk: Same risks as Issues Bump cross-spawn from 7.0.3 to 7.0.6 in /vue/vue-ethers #1 and Bump secp256k1 from 5.0.0 to 5.0.1 in /react/react-wagmi #2
- Impact: Same impacts as Issues Bump cross-spawn from 7.0.3 to 7.0.6 in /vue/vue-ethers #1 and Bump secp256k1 from 5.0.0 to 5.0.1 in /react/react-wagmi #2
- Trigger: Same triggers as Issues Bump cross-spawn from 7.0.3 to 7.0.6 in /vue/vue-ethers #1 and Bump secp256k1 from 5.0.0 to 5.0.1 in /react/react-wagmi #2
Recommendation: Apply same fixes as Issues #1 and #2 to React example

🤖 Auto Review Issue: Clipboard API without error handling
Severity: LOW
Category: code_quality
Tool: Claude Auto Review
Context:
- Pattern:
navigator.clipboard.writeText()at line 47 can fail (permissions, HTTPS required, browser support) - Risk: Silent failure in browsers without clipboard support or when user denies permission
- Impact: User clicks "Copy" but nothing happens, no feedback on success/failure
- Trigger: Non-HTTPS context, denied permissions, unsupported browsers
Recommendation: Add error handling and user feedback:
onClick={async () => {
try {
await navigator.clipboard.writeText(wcUri)
// Show success toast/message
} catch (err) {
console.error('Failed to copy:', err)
// Fallback: select text or show error message
}
}}Summary
Solid implementation following AppKit patterns. Config properly uses ssr: true for Next.js, createAppKit called at module level, networks imported correctly. Main issues: missing useEffect dependencies, lack of error handling in async operations, and missing cleanup for timers. No security vulnerabilities found.
