84-89: Consider enhancing error handling for last slot queryThe error from
GetSlotis logged but not propagated, which could mask underlying RPC connectivity issues. Consider propagating this error or implementing a retry mechanism for critical RPC calls.lastSlot, errSlot := ob.solClient.GetSlot(ctx, rpc.CommitmentFinalized) if errSlot != nil { - ob.Logger().Inbound.Err(errSlot).Msg("unable to get last slot") + ob.Logger().Inbound.Error().Err(errSlot).Msg("unable to get last slot") + // Consider implementing exponential backoff retry for RPC calls + // return errors.Wrap(errSlot, "failed to get last finalized slot") }

1-11: Consider making MaxSignaturesPerTicker configurableWhile 100 signatures per ticker is a reasonable default, this critical parameter affects system performance and resource usage. Consider making it configurable through chain parameters to allow runtime tuning.
Line range hint
150-300: Consider refactoring FilterInboundEvents for better maintainabilityWhile the function is well-documented, its length and complexity make it harder to maintain. Consider:
- Extracting deposit parsing logic into separate methods
- Creating a common logging helper for duplicate patterns
- Using a strategy pattern for different deposit types
+ // Example refactored structure: + func (ob *Observer) parseDeposit(tx *solana.Transaction, i int, slot uint64) (*Deposit, error) + func (ob *Observer) parseDepositSPL(tx *solana.Transaction, i int, slot uint64) (*Deposit, error) + func (ob *Observer) logDepositEvent(sig string, i int, depositType string)

98-103: LGTM: Well-structured metrics update logic
The implementation correctly updates the last scanned block metric even when no new signatures are found, which aligns with the PR objective to update metrics more frequently. The error check before updating metrics prevents incorrect updates.

31-31: LGTM: Changes properly documented in changelog
The changelog entry accurately reflects the implementation changes for more frequent updates of the last_scanned_block_number metrics.
Description
The
last_scanned_block_numbermetrics in Solana is updated only when there are new gateway transactions detected. In a low traffic period of time, the value of the metrics won't be increasing and reflecting the actual progress of inbound scanner.Fix:
last_scanned_block_number.How Has This Been Tested?
