-## Overview
-
-The L1 block attributes transaction is updated to include the operator fee parameters.
-
-| Input arg         | Type    | Calldata bytes | Segment |
-| ----------------- | ------- | -------------- | ------- |
-| {0x098999be}      |         | 0-3            | n/a     |
-| baseFeeScalar     | uint32  | 4-7            | 1       |
-| blobBaseFeeScalar | uint32  | 8-11           |         |
-| sequenceNumber    | uint64  | 12-19          |         |
-| l1BlockTimestamp  | uint64  | 20-27          |         |
-| l1BlockNumber     | uint64  | 28-35          |         |
-| basefee           | uint256 | 36-67          | 2       |
-| blobBaseFee       | uint256 | 68-99          | 3       |
-| l1BlockHash       | bytes32 | 100-131        | 4       |
-| batcherHash       | bytes32 | 132-163        | 5       |
-| operatorFeeScalar   | uint32  | 164-167      | 6       |
-| operatorFeeConstant | uint64  | 168-175      |         |
-
-Note that the first input argument, in the same pattern as previous versions of the L1 attributes transaction,
-is the function selector: the first four bytes of `keccak256("setL1BlockValuesIsthmus()")`.
-
-In the activation block, there are two possibilities:
-- If Isthmus is active at genesis, there are no transactions in the activation block
-and therefore no L1 Block Attributes transaction to consider.
-- If Isthmus activates after genesis [`setL1BlockValuesEcotone()`](../ecotone/l1-attributes.md)
-method must be used. This is because the L1 Block contract will not yet have been upgraded.
-
-In each subsequent L2 block, the `setL1BlockValuesIsthmus()` method must be used.
-
-When using this method, the pre-Isthmus values are migrated over 1:1
-and the transaction also sets the following new attributes to the values
-from the [`SystemConfig`](./system-config.md):
-
-- `operatorFeeScalar`
-- `operatorFeeConstant`

+# L1 Block Attributes
+
+## Overview
+
+The L1 block attributes transaction is updated to include the operator fee parameters.
+
+| Input arg | Type | Calldata bytes | Segment |
+| :--- | :--- | :--- | :--- |
+| {0x3db6be2b} | | 0-3 | n/a |
+| baseFeeScalar | uint32 | 4-7 | 1 |
+| blobBaseFeeScalar | uint32 | 8-11 | |
+| sequenceNumber | uint64 | 12-19 | |
+| l1BlockTimestamp | uint64 | 20-27 | |
+| l1BlockNumber | uint64 | 28-35 | |
+| basefee | uint256 | 36-67 | 2 |
+| blobBaseFee | uint256 | 68-99 | 3 |
+| l1BlockHash | bytes32 | 100-131 | 4 |
+| batcherHash | bytes32 | 132-163 | 5 |
+| operatorFeeScalar | uint32 | 164-167 | 6 |
+| operatorFeeConstant | uint64 | 168-175 | |
+
+Note that the first input argument is the function selector: the first four bytes of `keccak256("setL1BlockValuesJovian()")`.
+
+In the activation block:
+- If Jovian is active at genesis, there are no transactions.
+- If Jovian activates after genesis, the `setL1BlockValuesIsthmus()` method is used initially.
+
+In each subsequent L2 block, the `setL1BlockValuesJovian()` method must be used. This method ensures that the `daFootprintGasScalar` and `tokenRatio` parameters are correctly applied.
+
+When using this method, the transaction sets the following new attributes:
+- `operatorFeeScalar`
+- `operatorFeeConstant`
+- `daFootprintGasScalar`
+- `tokenRatio`
