57-58: Add NatSpec documentation for the new function.
The function addition looks good and serves a clear purpose. However, consider adding NatSpec documentation to explain the function's purpose and return value.
+ /// @notice Returns the maximum quote index that can be used in quote-related functions
+ /// @return The highest valid quote index

336-365: Add descriptive documentation for the MaxQuoteIndex method.
While the implementation is correct, consider adding a description of the method's purpose and return value in the comments, similar to other methods in the contract. This would help users understand what the maximum quote index represents and how it should be used.
Add documentation like this:
// MaxQuoteIndex is a free data retrieval call binding the contract method 0xec5af586.
//
+// Returns the maximum quote index that has been used so far. This can be used to
+// determine the valid range for quote lookups and to track the total number of quotes.
+//

58-58: Verify integration with quote functions.
The new function complements the existing quote functionality, particularly getQuote() which accepts a quote index parameter. Let's verify that other functions using quote indices are properly bounded by this value.
✅ Verification successful
Based on the gathered information, I can now provide a final response:
Proper bounds checking for quoteIndex is implemented
The codebase shows that quoteIndex bounds checking is properly implemented in the BridgeFeeQuote contract. Specifically:
- The
quotefunction validates that_input.quoteIndex < maxQuoteIndexbefore processing - The
getQuotefunction uses the index as part of the asset key for quote retrieval - All quote-related functions maintain consistency with this boundary

63-63: LGTM! ABI updated correctly for the new method.
The ABI has been properly extended to include the new maxQuoteIndex method with appropriate view modifier and return type.
336-351: Verify integration with GetQuote functionality.
The new MaxQuoteIndex method appears to be related to the GetQuote function which accepts an index parameter. Let's verify that these functions work together as expected.
✅ Verification successful
Integration between MaxQuoteIndex and GetQuote is properly implemented
Based on the code analysis, the integration between MaxQuoteIndex and GetQuote is correctly implemented in the smart contract:
maxQuoteIndexis used as a boundary check in the quote creation process:
if (_input.quoteIndex >= maxQuoteIndex) {
revert QuoteIndexInvalid();
}- It's also used to size quote arrays in related functions:
QuoteInfo[] memory quotesList = new QuoteInfo[](maxQuoteIndex);
for (uint256 i = 0; i < maxQuoteIndex; i++) {
// ... quote processing ...
}The Go bindings correctly expose this functionality, allowing callers to verify quote indices are within bounds before making quote-related calls.
