PublicationBatcher

Git Source

Inherits: IVersioned

Title: PublicationBatcher

Publishes market summaries and execution depth in one transaction.

Immutable, non-upgradeable forwarding contract. Existing target validation and events are preserved, including SlippageStorage's per-source skips. Governance must grant this contract WRITER_ROLE on both destinations.

Notes:

• security: Only the fixed writer can call the two fixed publication selectors.

• security-contact: team@quantillon.money

Constants

writer

Account authorized to submit combined publications.

address public immutable writer

priceStore

SlippageStorage destination for market summaries.

address public immutable priceStore

depthStore

ExecutionPricing destination for executable order books.

address public immutable depthStore

PRICE_SELECTOR

The sole allowed SlippageStorage entry point.

bytes4 private constant PRICE_SELECTOR =
    bytes4(keccak256("updateSlippageBatch((uint8,uint128,uint128,uint16,uint16,uint16[5])[])"))

DEPTH_SELECTOR

The sole allowed ExecutionPricing entry point.

bytes4 private constant DEPTH_SELECTOR =
    bytes4(keccak256("publish(uint256,(uint128,uint128)[],(uint128,uint128)[])"))

Functions

constructor

Fix the writer and both publication destinations for this deployment.

The writer cannot be either destination, preventing target callbacks.

Notes:

• security: Targets must contain code and be distinct from the writer and each other.

• validation: Nonzero writer, deployed and distinct destinations.

• state-changes: Sets immutable deployment bindings.

• events: None.

• errors: InvalidAddress on invalid bindings.

• reentrancy: No external calls.

• access: Deployment only.

• oracle: No oracle reads.

constructor(address publisher, address price, address depth) ;

Parameters

publishTogether

Forward both reports atomically, market summaries first.

Revert data is propagated unchanged. No ETH, delegatecall, generic calls or role management is exposed. A target revert rolls back both calls; a source silently skipped by SlippageStorage remains skipped.

Notes:

• security: Fixed caller, targets and selectors; callbacks from targets cannot reenter.

• validation: Caller and selectors here; report validation in each destination.

• state-changes: Updates destination reports; no local storage writes.

• events: Destination SlippageSourceUpdated and BookPublished events.

• errors: NotAuthorized, InvalidParameter, and unmodified destination errors.

• reentrancy: Target callbacks fail the immutable writer check.

• access: Only the immutable writer.

• oracle: Preserves both destinations' oracle and freshness validation.

function publishTogether(bytes calldata priceCall, bytes calldata depthCall) external;

Parameters

version

Return the semantic version of this contract.

Compile-time constant for deployment provenance.

Notes:

• security: Read-only metadata.

• validation: None.

• state-changes: None.

• events: None.

• errors: None.

• reentrancy: No external calls.

• access: Public.

• oracle: None.
