web/src/components/ui/transaction-toast.tsx (1)
41-41: Consider making hash truncation configurable.The current truncation shows 6 characters at the start and 4 at the end. This might not be optimal for all use cases.
interface TransactionToastProps { hash: `0x${string}`; chainId: number; success?: boolean; message?: string; + truncateLength?: { start: number; end: number }; } export const showTransactionToast = ({ hash, chainId, success = true, message = success ? "Transaction successful!" : "Transaction failed!", + truncateLength = { start: 6, end: 4 }, }: TransactionToastProps) => { // ... existing code ... - Transaction Hash: {hash.slice(0, 6)}...{hash.slice(-4)} + Transaction Hash: {hash.slice(0, truncateLength.start)}...{hash.slice(-truncateLength.end)}web/src/app/my-cats/page.tsx (1)
46-54: Transaction hash handling needs improvement.The success toast shows the transaction hash, but for a fetch operation, this might not provide meaningful value to users.
Consider whether users need to see transaction details for fetch operations:
useEffect(() => { if (fetchData) { showTransactionToast({ hash: fetchData, chainId: config.state.chainId, - message: "CATs fetched successfully!", + message: "CATs retrieval initiated - check results below", }); } }, [fetchData]);web/src/app/page.tsx (1)
152-157: Fix grammatical error in button text.The button text "My CAT's" has an incorrect apostrophe. It should be "My CATs" for the plural form.
<Button onClick={() => router.push("/my-cats")} className="mb-2 mr-2 text-black dark:text-white" > - My CAT's + My CATs </Button>web/src/app/[cat]/InteractionClient.tsx (1)
182-230: Consider consolidating repetitive transaction toast logic.You have 5 nearly identical
useEffecthooks for showing transaction toasts. Consider creating a reusable hook to reduce code duplication:// Add this custom hook at the top of the component const useTransactionToast = ( transactionData: `0x${string}` | undefined, message: string ) => { useEffect(() => { if (transactionData && chainId) { showTransactionToast({ hash: transactionData, chainId: chainId, message: message, }); } }, [transactionData, chainId, message]); }; // Then replace all the individual useEffects with: useTransactionToast(mintData, "Tokens minted successfully!"); useTransactionToast(reduceMaxSupplyData, "Max supply updated successfully!"); useTransactionToast(reduceThresholdSupplyData, "Threshold supply updated successfully!"); useTransactionToast(reduceMaxExpansionRateData, "Max expansion rate updated successfully!"); useTransactionToast(disableTransferRestrictionData, "Transfer restriction disabled successfully!");

❓ Verification inconclusive
Clarify the purpose of wagmi hooks for a fetch operation.
The use of
useWriteContractanduseWaitForTransactionReceiptsuggests this is performing a write transaction, but the function namefetchCATsimplies a read operation. This could be confusing.Can you clarify whether fetching CATs requires a write transaction? If this is purely reading data, consider using
useReadContractinstead.
🏁 Script executed:
#!/bin/bash # Check if there are other read-only CAT fetching implementations ast-grep --pattern $'useReadContract({ $$$ functionName: "getCATAddresses", $$$ })'Length of output: 90
Clarify whether fetching CATs should be a read or write transaction
I searched for any existing
useReadContractcalls forgetCATAddressesand found none. That suggests we’re only using write hooks here to “fetch” data:
- File:
web/src/app/my-cats/page.tsx- Lines: 41–44
Current code:
const { writeContract: fetchCATs, data: fetchData } = useWriteContract(); const { isLoading: isFetching } = useWaitForTransactionReceipt({ hash: fetchData, });Please verify:
- Is “fetching CATs” actually performing an on-chain write?
- If this is purely a read operation (e.g. calling
getCATAddresses), switch touseReadContractfor clarity and to avoid unnecessary transactions.web/src/app/page.tsx (2)
59-67: Address validation implementation is correct.The regex pattern
^0x[a-fA-F0-9]{40}$correctly validates Ethereum address format (40 hex characters after 0x prefix).
272-333: Excellent UI improvements for the dialog.The enhanced styling, better labeling, improved accessibility, and consistent dark mode support significantly improve the user experience.
web/src/app/create/page.tsx (1)
86-89: Good refactoring to use React hooks pattern!The migration from direct
writeContractcalls touseWriteContractanduseWaitForTransactionReceipthooks aligns with React best practices and provides better state management for transaction lifecycle.web/src/app/[cat]/InteractionClient.tsx (2)
133-139: Good addition of transfer restriction state management!Reading the
transferRestrictedstate from the contract and storing it locally enables proper conditional rendering of the UI. The implementation correctly handles the asynchronous contract read.
432-461: Well-implemented conditional UI for transfer restrictions!The conditional rendering based on
transferRestrictedstate provides clear user feedback. The UI appropriately shows either the disable button or an informational message.

We’ll need a more reliable check that follows redirects and actually hits a tx-URL (even with a dummy hash) instead of plain HEAD on the root. Please try this:
This follows redirects (-L), targets the real /tx/ path with a dummy hash, and flags truly unreachable endpoints. Once you confirm all bases respond (codes like 200, 3xx, 4xx, etc.), the mapping is good.

Two fixes needed: hash validation & Milkomeda testnet URL
- Add transaction-hash format validation before looking up the base URL:
export const getExplorerUrl = (hash: `0x${string}`, chainId: number): string => {
+ // Ensure 0x + 64 hex chars
+ if (!/^0x[a-fA-F0-9]{64}$/.test(hash)) {

https://explorer.testnet.milkomeda.com/tx/
but this host fails DNS resolution. Please verify and replace it with the correct Milkomeda testnet explorer URL inweb/src/utils/explorer.ts:
const baseUrls: { [key: number]: string } = {
…,
- 2001: "https://explorer.testnet.milkomeda.com/tx/",

In web/src/components/ui/transaction-toast.tsx at line 18, the call to
getExplorerUrl(hash, chainId) may throw an error for unsupported chain IDs,
causing the toast component to fail rendering. Wrap this call in a try-catch
block to handle potential errors gracefully. In the catch block, set explorerUrl
to a safe default value (e.g., null or an empty string) to ensure the component
continues rendering without crashing.

Avoid using dummy hash for error notifications.

Improve error handling to avoid misleading transaction notifications.
The current error handling shows a transaction toast with a dummy hash "0x0" when deployment fails. This is misleading because it suggests a transaction was submitted when it may have failed before reaching the blockchain (e.g., user rejected the transaction, validation errors, etc.).
Consider handling pre-transaction errors differently from transaction failures:
} catch (error) {
console.error("Error deploying CAT:", error);
- showTransactionToast({
- hash: "0x0" as `0x${string}`,
- chainId: config.state.chainId,

In web/src/app/create/page.tsx around lines 135 to 144, the error handling shows
a transaction toast with a dummy hash "0x0" on deployment failure, which can
mislead users into thinking a transaction was submitted. To fix this,
differentiate between pre-transaction errors (like user rejection or validation
errors) and actual transaction failures. For pre-transaction errors, avoid
showing a transaction toast or show a distinct notification indicating no
transaction was submitted. Only show the transaction toast with a valid hash
when a transaction is actually sent and fails.

@ceilican Thank you for confirming! The fix will make the error handling much clearer for users by distinguishing between pre-transaction failures and actual transaction errors.
Would you like me to plan the code changes for this improvement, or are you planning to implement it yourself?

Add null check for chainId to prevent runtime errors.
The non-null assertion operator (!) on chainId could cause runtime errors if chainId is null. Add a safety check:
useEffect(() => {
- if (mintData) {
+ if (mintData && chainId) {
showTransactionToast({
hash: mintData,
- chainId: chainId!,
+ chainId: chainId,
message: "Tokens minted successfully!",
});
}
}, [mintData, chainId]);This same issue appears in all the transaction toast useEffect hooks (lines 192-230). Apply the same fix to all of them.

In web/src/app/[cat]/InteractionClient.tsx around lines 182 to 190 and also in
the useEffect hooks from lines 192 to 230, the code uses the non-null assertion
operator on chainId which can cause runtime errors if chainId is null. To fix
this, add a null check to ensure chainId is defined before calling
showTransactionToast. Wrap the showTransactionToast call inside an if statement
that checks if chainId is not null or undefined in all these useEffect hooks.
