Walkthrough

The changes across the four files primarily involve the introduction of optional chaining (?.) in various functions and methods. This enhancement improves the handling of potential null or undefined values, making the code more robust and less prone to runtime errors.

Changes

File Path	Change Summary
.../Portfolio/Transaction/MostRecentTransaction.tsx	Replaced some with optional chaining (?.) in MostRecentTransaction function for better handling of potential null or undefined values.
.../synapse-interface/slices/transactions/updater.tsx	Introduced optional chaining in several places for safer property access. Adjusted variable declarations and comparisons to incorporate optional chaining.
.../utils/hooks/useFallbackBridgeDestinationQuery.tsx	Modified fallbackQueryHistoricalTransactions to use optional chaining when checking for existence before invoking the some method.
.../utils/hooks/useFallbackBridgeOriginQuery.tsx	Introduced optional chaining to several occurrences of fallbackQueryPendingTransactions, fallbackQueryHistoricalTransactions, and userHistoricalTransactions.

Poem

🍂 As autumn leaves gently fall,
Code changes we do install.
With optional chaining in our sight,
We make our code robust and right. 🛠️

On this day, in history's page,
The Berlin Wall fell, a new age.
Just as walls crumbled, so does fear,
When code is clean and errors clear. 🎉

So here's to changes, big and small,
To a codebase standing tall.
With each update, we create,
A future that's truly great. 🌟

Additional comments: 4

packages/synapse-interface/utils/hooks/useFallbackBridgeDestinationQuery.tsx (1)

• 113-119: The use of optional chaining here is a good practice to prevent potential null or undefined errors. However, ensure that the comparison transaction?.toInfo === destinationInfo is the intended logic as it will return false if transaction?.toInfo is undefined due to optional chaining.

packages/synapse-interface/utils/hooks/useFallbackBridgeOriginQuery.tsx (2)

• 49-55: The use of optional chaining (?.) here is a good practice to avoid potential null or undefined errors. It ensures that the some method is only called if fallbackQueryPendingTransactions is defined.

• 96-112: Again, the use of optional chaining (?.) is a good practice to avoid potential null or undefined errors. It ensures that the some method is only called if fallbackQueryPendingTransactions, fallbackQueryHistoricalTransactions, and userHistoricalTransactions are defined.

packages/synapse-interface/slices/transactions/updater.tsx (1)

• 287-301: The use of optional chaining (?.) here is a good practice to avoid potential TypeError when the object is undefined or null. However, the code could be simplified by removing the redundant checks for userHistoricalTransactions and fallbackQueryHistoricalTransactions before using optional chaining. The optional chaining operator already checks if the object is null or undefined before attempting to access its properties.

- const isCompleted: boolean =
-   userHistoricalTransactions?.some(
-     (historicalTransaction: BridgeTransaction) => {
-       return (
-         historicalTransaction.fromInfo.txnHash ===
-         pendingBridgeTransaction.transactionHash
