0 / 5 completed⚠️ MEV & Censorship Risks
Centralized sequencers create opportunities for MEV extraction and censorship. Understanding these risks is essential for both users and protocol designers.

Select a MEV attack type to understand how sequencers can extract value from their privileged position.
Front-Running
Sequencer sees profitable transaction and inserts their own transaction before it
Real Example:
User swaps $100K DAI→ETH. Sequencer buys ETH first, then user's swap executes at worse price.
Mitigation Strategies:

Adjust censorship level to see how transaction filtering affects the network and users.
Time until tx included
User perception of fairness
Protocol credibility
Additional MEV revenue
🛡️ Protection Mechanisms
Forced Inclusion Queue
Users can submit transactions directly to L1 that the sequencer must include within a time limit (e.g., 24 hours).
Proof of Censorship
Cryptographic proofs that sequencer excluded valid transactions. Can trigger slashing or penalties.
Private Mempools
Flashbots Protect, MEV Blocker, and other services hide transactions until execution.
MEV-Share Programs
Redistribute MEV profits back to users instead of only to sequencer operators.
