28-33: Add documentation and improve error handling.The function logic looks correct, but could benefit from the following improvements:
- Add documentation explaining the function's purpose and fallback behavior
- Consider logging the error case for debugging purposes
- Validate for potential overflow in the fallback calculation
Here's the suggested implementation:
+/// Retrieves the genesis time from chain info with fallback handling. +/// +/// Returns either the genesis time if available, or calculates it from +/// min_genesis_time + genesis_delay if genesis time cannot be retrieved. pub fn get_genesis_time_with_delay(chain_info: &ChainInfo) -> u64 { match chain_info.context.genesis_time() { Ok(genesis_time) => genesis_time, - Err(_) => chain_info.context.min_genesis_time + chain_info.context.genesis_delay, + Err(e) => { + tracing::warn!("Failed to get genesis time: {}, using fallback calculation", e); + chain_info.context.min_genesis_time + .checked_add(chain_info.context.genesis_delay) + .expect("Genesis time calculation overflow") + } } }

28-33: Verify consistent behavior across the codebase.
Let's verify that this new function maintains consistent behavior with the previous implementation it replaces.
✅ Verification successful
Based on the search results, I can now generate the final response:
The new get_genesis_time_with_delay function maintains consistent behavior across the codebase
The function is used consistently across multiple components:
- In
chain_event_updater.rsfor slot timestamp calculations - In
proposer/api.rsfor various timing-related operations including slot start times and cutoffs - In
builder/api.rsfor timestamp validation
The implementation correctly handles both successful genesis time retrieval and fallback to min_genesis_time + genesis_delay. No other direct access to these fields exists in the codebase, ensuring centralized and consistent genesis time handling.

16-16: LGTM: Import addition is correct.
The import of get_genesis_time_with_delay is properly placed and used in the code.
131-132: Verify the impact of genesis time delay on slot validation.
The change to use get_genesis_time_with_delay looks correct. However, since this affects slot timestamp validation, we should verify that the added delay doesn't cause valid slots to be incorrectly rejected.
Let's verify the genesis time delay implementation:
✅ Verification successful
Genesis time delay implementation is safe for slot validation
The implementation is correct and safe because:
get_genesis_time_with_delayproperly handles both success and failure cases:- Returns actual genesis time on success
- Falls back to
min_genesis_time + genesis_delayon failure
- The slot validation logic using
MAX_DISTANCE_FOR_FUTURE_SLOT(60 seconds) remains unchanged - The timestamp calculation (
genesis_time + (slot * seconds_per_slot)) is consistent across all usages in the codebase
The delay won't cause valid slots to be rejected since it's only used when the genesis time cannot be retrieved, providing a safe fallback value.

1650-1652: Verify the impact of the genesis time delay on block submissions.
The change from get_genesis_time to get_genesis_time_with_delay modifies how the expected block timestamp is calculated. This could affect the validation of block submissions, particularly for blocks near the chain genesis or during network initialization.
✅ Verification successful
Let me gather more information about the genesis time handling to better understand the impact.
Let me check one more aspect to understand the implementation details of the genesis time delay.
Based on the gathered information, I can now provide the final response:
The genesis time delay change is a valid implementation with proper configuration support
The change from get_genesis_time to get_genesis_time_with_delay is part of a well-structured system where:
- The delay is configurable through validator preferences (
header_delayboolean flag) - The implementation is consistently used across proposer and builder APIs
- The genesis delay is properly handled using chain configuration (
chain_info.context.genesis_delay) - The timestamp validation logic remains correct as it uses the delayed genesis time for all block submissions
The change ensures consistent timestamp calculations across the system while maintaining proper validation of block submissions.

32-32: Approved: Added import for get_genesis_time_with_delay
The import statement correctly adds get_genesis_time_with_delay from helix_common.
853-853: Verify timing calculations after replacing get_genesis_time with get_genesis_time_with_delay
The replacement of get_genesis_time with get_genesis_time_with_delay in validate_set_constraints_request may affect timing calculations for constraints validation. Please ensure this change aligns with the intended logic, considering any additional delay introduced.
970-970: Verify timing calculations with get_genesis_time_with_delay in validate_bid_request_time
Please confirm that using get_genesis_time_with_delay in validate_bid_request_time maintains the correct timing logic, especially regarding request cutoff times.
1165-1165: Ensure correct timing with get_genesis_time_with_delay in get_execution_payload
In get_execution_payload, get_genesis_time_with_delay is used to calculate slot_time. Verify that this change maintains accurate timing for payload retrieval and does not introduce unintended delays.
1325-1325: Confirm the use of get_genesis_time_with_delay in calculate_slot_time_info
The function get_genesis_time_with_delay replaces get_genesis_time in calculate_slot_time_info. Please ensure that this change accurately reflects the required timing calculations and that passing chain_info directly is appropriate.
