Summary by CodeRabbit

  • New Features

    • Deployment configuration now supports setting an optional first sequencer, active from L2 block 0.
    • The configured sequencer address is validated and registered automatically during deployment.
  • Bug Fixes

    • Sequencer registration is skipped safely when no address is configured or sequencer history already exists.
  • Chores

    • Updated Ethereum and Tendermint components to newer revisions across project modules.

A zero first-sequencer address stops deployment initialization instead of failing during configuration validation. Add the local check before merge.

Reject the zero address before sending the transaction.

When the history is empty, ethers.utils.isAddress accepts ethers.constants.AddressZero, and L1Sequencer.setFirstSequencer then reverts with invalid address instead of returning invalid firstSequencerAddress.

Proposed fix
-    if (!ethers.utils.isAddress(firstSequencer)) {
+    if (
+        !ethers.utils.isAddress(firstSequencer) ||
+        firstSequencer.toLowerCase() === ethers.constants.AddressZero
+    ) {
         return `invalid firstSequencerAddress: ${firstSequencer}`
     }

Reject the zero address before calling setFirstSequencer. ethers.utils.isAddress accepts ethers.constants.AddressZero, so a zero firstSequencerAddress reaches L1Sequencer.setFirstSequencer. The contract rejects it with "invalid address", which causes the deployment task to stop before registering the first sequencer.
