Submission Details
Severity:
Missing checks for whether the Sequencer is active
Summary
If the sequencer goes down, the Chainlink oracles will have stale prices from before the downtime, until a new L2 OCR transaction goes through. Users who submit their transactions via the L1 Dealyed Inbox will be able to take advantage of these stale prices. Use a Chainlink oracle to determine whether the sequencer is offline or not, and don't allow operations to take place while the sequencer is offline.
