Subject: [PATCH 01/16] feat(sepolia): add task to set Jovian parameters on
 Base Sepolia

This task sets the Jovian hardfork parameters on Base Sepolia's SystemConfig:
- setDAFootprintGasScalar(260) - Sets DA footprint gas scalar
- setMinBaseFee(5000000) - Sets minimum base fee to 5M wei

These parameters activate with the Jovian hardfork.

+# Set Jovian Parameters on Base Sepolia
+
+Status: NOT YET EXECUTED
+
+## Description
+
+This task sets the Jovian hardfork parameters on Base Sepolia's SystemConfig contract. The parameters being set are:
+
+- `setDAFootprintGasScalar(260)` - Sets the data availability footprint gas scalar
+- `setMinBaseFee(5000000)` - Sets the minimum base fee
+
+These parameters activate with the Jovian hardfork and affect data availability fee calculations and base fee management on the L2.
+
+## Procedure
+
+### 1. Update repo:
+
+```bash
+cd contract-deployments
+git pull
+cd sepolia/2025-11-03-set-jovian-parameters
+make deps
+```
+
+### 2. Setup Ledger
+
+Your Ledger needs to be connected and unlocked. The Ethereum
+application needs to be opened on Ledger with the message "Application
+is ready".
+
+### 3. Simulate, Validate, and Sign
+
+#### 3.1. Simulate and validate the transaction
+
+Make sure your ledger is still unlocked and run the following command:
+
+```bash
+make sign
+```
+
+You will see a "Simulation link" from the output.
+
+Paste this URL in your browser. A prompt may ask you to choose a
+project, any project will do. You can create one if necessary.
+
+Click "Simulate Transaction".
+
+We will be performing 3 validations and extract the domain hash and
+message hash to approve on your Ledger:
+
+1. Validate integrity of the simulation.
+2. Validate correctness of the state diff.
+3. Validate and extract domain hash and message hash to approve.
+
+##### 3.1.1. Validate integrity of the simulation.
+
+Make sure you are on the "Overview" tab of the tenderly simulation, to
+validate integrity of the simulation, we need to check the following:
+
+1. "Network": Check the network is `Sepolia`.
+2. "Timestamp": Check the simulation is performed on a block with a
+   recent timestamp (i.e. close to when you run the script).
+
+##### 3.1.2. Validate correctness of the state diff.
+
+Now click on the "State" tab, and refer to the [VALIDATION.md](./VALIDATION.md) instructions. Once complete return to this document to complete the signing.
+
+#### 3.2. Extract the domain hash and the message hash to approve.
+
+Now that we have verified the transaction performs the right
+operation, we need to extract the domain hash and the message hash to
+approve.
+
+Go back to the "Overview" tab, and find the
+`GnosisSafe.checkSignatures` call. This call's `data` parameter
+contains both the domain hash and the message hash that will show up
+in your Ledger.
+
+It will be a concatenation of `0x1901`, the domain hash, and the
+message hash: `0x1901[domain hash][message hash]`.
+
+Note down this value. You will need to compare it with the ones
+displayed on the Ledger screen at signing.
+
+#### 3.3. Sign the transaction
+
+Once the validations are done, a prompt will appear on the Ledger
+for you to sign a transaction. Before accepting, scroll to the screen that
+shows:
+
+```
+EIP712 DOMAIN_HASH
+```
+
+It will look something like this:
+
+```
+DOMAIN_HASH
+0x454a4be2...
+```
+
+Compare this hash with the domain hash you extracted earlier. If they match,
+continue scrolling to the screen that shows:
+
+```
+EIP712 MESSAGE_HASH
+```
+
+It will look something like this:
+
+```
+MESSAGE_HASH
+0x6f21c9af...
+```
+
+Compare this hash with the message hash you extracted earlier. If they match,
+accept the transaction on your Ledger.
+
+A `data` field will be printed in the console. **This is the signature you just created.**
+
+### 4. Approve and Execute
+
+Once signatures have been collected, the transaction can be approved and executed following the same validation process above.

Subject: [PATCH 02/16] feat(sepolia): add gen-validation for Jovian parameters
 task

Adds gen-validation target to Makefile for generating VALIDATION.md
automatically once the Jovian upgrade is deployed to Base Sepolia.

VALIDATION.md currently contains only a comment explaining it cannot
be generated yet because the setDAFootprintGasScalar and setMinBaseFee
functions don't exist on the current SystemConfig deployment.

Once the Jovian upgrade is deployed, run `make gen-validation` to
generate the full validation file with state-diff.

Subject: [PATCH 03/16] feat(sepolia): update DA footprint gas scalar to 325
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Updates DA_FOOTPRINT_GAS_SCALAR from 260 to 325 based on the formula:
da_footprint_gas_scalar = gas_target / (l1_target_throughput * estimation_ratio)

Where:
- l1_target_throughput = (blob_count * 128,000 bytes/blob) / 12 sec/block
- gas_target = 31.25 Mgas/sec
- blob_count = 6 blobs/block
- estimation_ratio = 1.5

Calculation:
l1_target_throughput = (6 * 128,000) / 12 = 64,000 gas/sec
da_footprint_gas_scalar = 31,250,000 / (64,000 * 1.5) = 325.52 ≈ 325

-# Set Jovian Parameters on Base Sepolia
-
-Status: NOT YET EXECUTED
-
-## Description
-
-This task sets the Jovian hardfork parameters on Base Sepolia's SystemConfig contract. The parameters being set are:
-
-- `setDAFootprintGasScalar(260)` - Sets the data availability footprint gas scalar
-- `setMinBaseFee(5000000)` - Sets the minimum base fee
-
-These parameters activate with the Jovian hardfork and affect data availability fee calculations and base fee management on the L2.
-
-## Procedure
-
-### 1. Update repo:
-
-```bash
-cd contract-deployments
-git pull
-cd sepolia/2025-11-03-set-jovian-parameters
-make deps
-```
-
-### 2. Setup Ledger
-
-Your Ledger needs to be connected and unlocked. The Ethereum
-application needs to be opened on Ledger with the message "Application
-is ready".
-
-### 3. Simulate, Validate, and Sign
-
-#### 3.1. Simulate and validate the transaction
-
-Make sure your ledger is still unlocked and run the following command:
-
-```bash
-make sign
-```
-
-You will see a "Simulation link" from the output.
-
-Paste this URL in your browser. A prompt may ask you to choose a
-project, any project will do. You can create one if necessary.
-
-Click "Simulate Transaction".
-
-We will be performing 3 validations and extract the domain hash and
-message hash to approve on your Ledger:
-
-1. Validate integrity of the simulation.
-2. Validate correctness of the state diff.
-3. Validate and extract domain hash and message hash to approve.
-
-##### 3.1.1. Validate integrity of the simulation.
-
-Make sure you are on the "Overview" tab of the tenderly simulation, to
-validate integrity of the simulation, we need to check the following:
-
-1. "Network": Check the network is `Sepolia`.
-2. "Timestamp": Check the simulation is performed on a block with a
-   recent timestamp (i.e. close to when you run the script).
-
-##### 3.1.2. Validate correctness of the state diff.
-
-Now click on the "State" tab, and refer to the [VALIDATION.md](./VALIDATION.md) instructions. Once complete return to this document to complete the signing.
-
-#### 3.2. Extract the domain hash and the message hash to approve.
-
-Now that we have verified the transaction performs the right
-operation, we need to extract the domain hash and the message hash to
-approve.
-
-Go back to the "Overview" tab, and find the
-`GnosisSafe.checkSignatures` call. This call's `data` parameter
-contains both the domain hash and the message hash that will show up
-in your Ledger.
-
-It will be a concatenation of `0x1901`, the domain hash, and the
-message hash: `0x1901[domain hash][message hash]`.
-
-Note down this value. You will need to compare it with the ones
-displayed on the Ledger screen at signing.
-
-#### 3.3. Sign the transaction
-
-Once the validations are done, a prompt will appear on the Ledger
-for you to sign a transaction. Before accepting, scroll to the screen that
-shows:
-
-```
-EIP712 DOMAIN_HASH
-```
-
-It will look something like this:
-
-```
-DOMAIN_HASH
-0x454a4be2...
-```
-
-Compare this hash with the domain hash you extracted earlier. If they match,
-continue scrolling to the screen that shows:
-
-```
-EIP712 MESSAGE_HASH
-```
-
-It will look something like this:
-
-```
-MESSAGE_HASH
-0x6f21c9af...
-```
-
-Compare this hash with the message hash you extracted earlier. If they match,
-accept the transaction on your Ledger.
-
-A `data` field will be printed in the console. **This is the signature you just created.**
-
-### 4. Approve and Execute
-
-Once signatures have been collected, the transaction can be approved and executed following the same validation process above.

+#### Execute the transaction
+
+1. Collect outputs from all participating signers.
+1. Concatenate all signatures and export it as the `SIGNATURES`
+   environment variable, i.e. `export
+SIGNATURES="[SIGNATURE1][SIGNATURE2]..."`.
+1. Run the `make execute` or `make approve` command as described below to execute the transaction.
+
+For example, if the quorum is 3 and you get the following outputs:
+
+```shell
+Data:  0xDEADBEEF
+Signer: 0xC0FFEE01
+Signature: AAAA
+```
+
+```shell
+Data:  0xDEADBEEF
+Signer: 0xC0FFEE02
+Signature: BBBB
+```
+
+```shell
+Data:  0xDEADBEEF
+Signer: 0xC0FFEE03
+Signature: CCCC
+```
+
+Coinbase facilitator:
+
+```bash
+SIGNATURES=AAAABBBBCCCC make approve-cb
+```
+
+```bash
+SIGNATURES=AAAABBBBCCCC make approve-cb-sc
+```
+
+```bash
+SIGNATURES=AAAABBBBCCCC make approve-op
+```
+
+Once the signatures have been submitted approving the transaction for all nested Safes run:
+
+```bash
+make execute
+```
