8-16: Consider expanding error states for better error handlingThe
AddToWalletStateValuestype could benefit from more specific error states to handle different failure scenarios (e.g., 'wallet_rejected', 'network_error', 'timeout_error'). This would enable more precise error messaging and recovery strategies.-export type AddToWalletStateValues = 'unknown' | 'adding' | 'added' | 'error' | 'takingTooLong' | 'connecting' +export type AddToWalletStateValues = + | 'unknown' + | 'adding' + | 'added' + | 'wallet_rejected' + | 'network_error' + | 'timeout_error' + | 'takingTooLong' + | 'connecting'

18-26: Consider using theme variables for better maintainabilityThe
Messagecomponent uses hardcoded colors. Consider:
- Moving colors to theme variables for consistency
- Verifying color contrast ratios for accessibility compliance
const Message = styled.p<{ state: AddToWalletStateValues }>` - color: ${({ state }) => (state === 'added' ? darken(0.5, 'green') : 'orange')}; + color: ${({ state, theme }) => (state === 'added' ? theme.colors.success : theme.colors.warning)}; font-weight: bold; width: 100%; margin: 2.4rem 0 0; - background: ${({ state }) => (state === 'added' ? transparentize(0.8, 'green') : transparentize(0.9, 'orange'))}; + background: ${({ state, theme }) => ( + state === 'added' + ? transparentize(0.8, theme.colors.success) + : transparentize(0.9, theme.colors.warning) + )}; padding: 1rem; border-radius: 1.2rem; text-align: center;

35-46: Enhance error handling and analyticsThe error handling in
handleClickcould be improved:
- The caught error is not utilized for user feedback
- Analytics event lacks error details
try { if (connectAndAddToWallet) { // Start the connection process const connectionPromise = connectAndAddToWallet() + // Add timeout protection + const timeoutPromise = new Promise((_, reject) => + setTimeout(() => reject(new Error('Connection timeout')), 30000) + ); - await connectionPromise + await Promise.race([connectionPromise, timeoutPromise]) } else { throw new Error('connectAndAddToWallet is not defined') } } catch (error) { - clickOnMevBlocker('click-add-rpc-to-wallet-error') + clickOnMevBlocker('click-add-rpc-to-wallet-error', { + error: error instanceof Error ? error.message : 'Unknown error' + }) }

49-57: Optimize button label calculationThe button label calculation logic could be memoized to prevent unnecessary recalculations.
+const getButtonLabel = (isConnecting: boolean, isAdding: boolean, isConnected: boolean) => { + if (isConnecting) return 'Connecting Wallet...' + if (isAdding) return 'Adding to Wallet...' + if (isConnected) return 'Add MEV Blocker RPC' + return 'Get protected' +} + // Get the label and enable state of button const isAdding = state === 'adding' const isConnecting = state === 'connecting' const disabledButton = isConnecting || isAdding || !connectAndAddToWallet -const buttonLabel = isConnecting - ? 'Connecting Wallet...' - : isAdding - ? 'Adding to Wallet...' - : isConnected - ? 'Add MEV Blocker RPC' - : 'Get protected' +const buttonLabel = useMemo( + () => getButtonLabel(isConnecting, isAdding, isConnected), + [isConnecting, isAdding, isConnected] +)
