Yesterday, over $1,5M was stolen from users by sandwich attacks on Ethereum Mainnet.

On @base it was just $1,044.

Base has ~50% of mainnet's DEX volume... It SHOULD be much closer right?

Here's why sandwiching hardly happens on @base... 🧵

2/ @base uses a centralized sequencer (run by @coinbase). No public mempool = no preview of pending transactions.

3/ We only see the transactions once confirmed. By then, sandwich opp is gone.

But what happens when the sequence becomes decentralised?

4/ It highlights a key challenge in shared sequencing: preventing information leakage that enables MEV without compromising decentralization.

This isn't just about Base - it's a fundamental challenge for all rollups pursuing decentralization.

1/ Ethereum mainnet has a public mempool. Attackers monitor pending transactions and can pay validators enough to front-run users.
