This PR adds the ability to use
block.timestampin custom AA contracts. AAs will still not have direct access toblock.timestamp, but can utilize it via a proxy that enforces certain constraints. The PR introduces aTimestampAssertercontract that is deployed on every chain to the user space, similar toMulticall3. This contract has a single function,assertTimestampInRange(start, end), which can be used by AAs at their discretion.The
TimestampAssertercontract ensures thatblock.timestampfalls within the specified(start, end)range. Additionally, the sequencer verifies that theblock.timestampis sufficiently far from the range’s end. This is to prevent DoS attacks where transactions pass validation but get stuck in the mempool during execution. This constraint is configurable and can be adjusted without requiring protocol update.The PR also introduces two new fields to the
transactionstable:timestamp_asserter_range_startandtimestamp_asserter_range_end. These fields are extracted during transaction execution in the sandbox by theValidationTracer. If multiple assertions are made in a single transaction, the system captures the maximum of the starts and the minimum of the ends, resulting in the narrowest possible time range.Transactions with time range constraints will undergo additional verification before being included in a block. If the current time falls outside the transaction’s specified time range, the transaction will be rejected with an appropriate message.
