Base previously announced its departure from the OP Stack Superchain ecosystem but did not specify when it would stop sharing sequencer revenue with the Optimism Collective. According to data from the Blockworks website, @base has updated its sequencer revenue sharing data with @Optimism up to February 27 (data for the 28th has not yet been updated). This indicates that, as of now, Base is still providing a steady stream of sequencer revenue sharing to the Optimism Collective. Since joining the OP Stack Superchain ecosystem, Base has contributed a total of 8,459.33 ETH to Optimism. At the current ETH price, this amounts to over $17 million.
