+# Code Review Findings
+
+### 1. Missing `blockchain` field
+
+`balance.blockchain` is used but does not exist in `WalletBalance`.
+
+**Fix:** Add `blockchain` to the interface.
+
+---
+
+### 2. Using `any`
+
+```ts
+blockchain: any;
+```
+
+**Problem:** Removes TypeScript safety.
+
+**Fix:** Use proper types or union types.
+
+---
+
+### 3. Undefined variable
+
+```ts
+lhsPriority;
+```
+
+does not exist.
+
+**Fix:** Replace with `balancePriority`.
+
+---
+
+### 4. Wrong filter condition
+
+```ts
+balance.amount <= 0;
+```
+
+**Problem:** Keeps invalid balances.
+
+**Fix:** Use `balance.amount > 0`.
+
+---
+
+### 5. Wrong `useMemo` dependency
+
+`prices` is included but not used.
+
+**Problem:** Causes unnecessary recalculation.
+
+**Fix:** Remove `prices` from dependency array.
+
+---
+
+### 6. Missing return in `sort`
+
+The sort callback does not return `0` when priorities are equal.
+
+**Fix:** Always return a number.
+
+---
+
+### 7. Unused `formattedBalances`
+
+`formattedBalances` is created but never used.
+
+**Fix:** Use it for rendering or remove it.
+
+---
+
+### 8. Wrong render source
+
+Rows are rendered from `sortedBalances` instead of `formattedBalances`.
+
+**Problem:** `formatted` becomes `undefined`.
+
+**Fix:** Render using `formattedBalances`.
+
+---
+
+### 9. Using index as key
+
+```tsx
+key = { index };
+```
+
+**Problem:** Can cause incorrect React rendering.
+
+**Fix:** Use stable unique keys.
+
+---
+
+### 10. Possible `NaN` value
+
+```ts
+prices[balance.currency];
+```
+
+may be undefined.
+
+**Fix:** Add fallback value like `0`.
+
+---
+
+### 11. Unused `children`
+
+`children` is destructured but never used.
+
+**Fix:** Remove it if unnecessary or render it.
+
+---
+
+### 12. `toFixed()` without precision
+
+```ts
+toFixed();
+```
+
+**Problem:** Rounds values too aggressively.
+
+**Fix:** Use `toFixed(2)` or `toFixed(6)`.
+
+---
+
+### 13. Repeated priority logic
+
+`getPriority()` is called many times and uses a long `switch` statement.
+
+**Problem:** Harder to maintain and creates repeated computation.
+
+**Fix:** Replace with a constant object map.
+
+Example:
+
+```ts
+const PRIORITY_MAP = {
+ Osmosis: 100,
+ Ethereum: 50,
+ Arbitrum: 30,
+ Zilliqa: 20,
+ Neo: 20,
+};
+```
+
+---
+
+### 14. Wrong type casting
+
+`sortedBalances` is typed as `FormattedWalletBalance`.
+
+**Problem:** Data does not contain `formatted`.
+
+**Fix:** Use correct types and correct data source.
+
+# Refactored Code
+
+```tsx
+type Blockchain = "Osmosis" | "Ethereum" | "Arbitrum" | "Zilliqa" | "Neo";
+
+interface WalletBalance {
+ currency: string;
+ amount: number;
+ blockchain: Blockchain;
+}
+
+interface FormattedWalletBalance extends WalletBalance {
+ formatted: number;
+}
+
+type Props = BoxProps;
+
+const PRIORITY_MAP: Record = {
+ Osmosis: 100,
+ Ethereum: 50,
+ Arbitrum: 30,
+ Zilliqa: 20,
+ Neo: 20,
+};
+
+const getPriority = (blockchain: string): number => {
+ return PRIORITY_MAP[blockchain] ?? -99;
+};
+
+const WalletPage: React.FC = ({ children, ...rest }) => {
+ const balances = useWalletBalances() ?? [];
+ const prices = usePrices() ?? {};
+
+ const formattedBalances = useMemo(() => {
+ return balances
+ .filter((balance) => {
+ const priority = getPriority(balance.blockchain);
+
+ return priority > -99 && balance.amount > 0;
+ })
+ .sort((a, b) => {
+ return getPriority(b.blockchain) - getPriority(a.blockchain);
+ })
+ .map((balance) => ({

+
+## Summary
+
+Fixed type safety issues, invalid filter logic, undefined variables, incorrect render source, unstable React keys, unnecessary `useMemo` dependencies, repeated priority calculations, and possible `NaN` values.
+
+Refactored priority handling using `PRIORITY_MAP` for cleaner and easier maintenance.
+
+Improved rendering flow by using `formattedBalances` correctly and adding proper formatting precision with `toFixed(2)`.
