+
+* Welcome Landon Gingerich from Matter Labs, standing in from Omar from here on out.
+* Review new work items
+  * Initial draft of the L2 transaction fee specification - https://github.com/eea-oasis/L2/pull/43
+    * Landon presented the transaction profile of zkSync Era and agrees with the need to standardize across other projects
+      * L1 Call Data, Gas Fee for Data Stored on the L2
+      * Suggestion made to standardize the calculation of base fees
+      * Additional discussion 
+      * Noted that zkSync Era works primarily on state differences
+    * Nikolai and Rami presented the Metis technical approach and will follow-up with more detail later after conferring with the team
+      * Does not include L2 data on L1
+      * Thinking about posting the data to L1 to support EIP 4844 or storing the data into the upcoming sequencer pool.
+    * Ideally we would have 2 gas prices, 1 for L2 and 1 for L1
+    * L1 data is estimated based on the size of the data
+    * Detailed notes on requirements captured from zkSync Era and Metis captured in issue: https://github.com/eea-oasis/L2/issues/48#issuecomment-1708539190
