Raw

We’re going to try to use this package to simulate the migration of an environment. A full migration should have these steps:

  1. Initial material setup and verification
  2. Pre-migration sync
  3. Soft-switch
  4. Clean-halt
  5. New sequencer
  6. Full switch over

This test is just a simulation, so we’ll skip the pre-migration sync where we would get a clean copy of the state db, bridge db, and DAC db.

The current sequencer is 0x3C3Ade761F53bdf4F3f40B46D0AbDA286C2aCDcC and the current admin is 0x66415f84060F1E29249854B3adD1005c13B179e8.

Admin Setup

Let’s first create a new wallet for the admin.

cast wallet new
Successfully created new keypair.
Address:     0xd03C837B1C09Dc463E3dC7Efc337E38Fb01fC158
Private key: 0x582fb4c16b0acd6c084d939ef1195a71205bd67621cd3ab78fd411c72938086f

We’ve got a new wallet to use as our admin. Let’s try to udpate the admin for our rollup?

That transaction worked, it looks like we have a new pending admin. I need to make a second call now to accept the admin role using the new wallet. Let’s try to accept the admin role.

DAC Setup

Alright, our rollup has a new admin now. We’ll also need to transfer ownership of the dac.

Now we should see if we can rotate a key for the DAC. In production it might be safer to add a few additional nodes rather than trying a migration like this.

Let’s create a new key for our DAC member:

cast wallet new
Successfully created new keypair.

Let’s update this value on chain

new_admin_pkey="0x582fb4c16b0acd6c084d939ef1195a71205bd67621cd3ab78fd411c72938086f"

Okay there should be a new DAC key for onchain verification. Unfortately, the application requires a keystore, so we’ll need to wrangle private key into a keystore file.

polycli parseethwallet --hexkey "0x941c1830f5dcb7439c2c6387840664bbe306323eee24f6000a30ab91ac782a58" --password "pSnv6Dh5s9ahuzGzH9RoCDrKAMddaX3m" --keystore /tmp/dac
cat /tmp/dac/UTC* | jq '.' | tee dac-new.keystore
{
  "address": "5018895310b962ac12b837fad66e177ac7863ca5",
  "crypto": {
    "cipher": "aes-128-ctr",
    "ciphertext": "994f3b65263a85b2cdc6d246d868dbc82dba4633b8b813689b06f981374bd1df",
    "cipherparams": {
      "iv": "14c034e7254c1f2338009ce201d54942"

  },
  "id": "71e11b91-7aa9-483b-95f0-7cc18a349b59",
  "version": 3
}

We now have a new file that we can use as the keystore for our dac. We’re going to copy this file into the image and restart it. If I run kurtosis enclave inspect cdk-v1 --full-uuids I’ll be able to get the UUID for the zkevm-dac-001 and then write a copy command to replace the current keystore.

docker cp dac-new.keystore zkevm-dac-001--d098ab1fe97e40b1a0c2a77331466c38:/etc/zkevm/dac.keystore
kurtosis service stop cdk-v1 zkevm-dac-001
kurtosis service start cdk-v1 zkevm-dac-001

I can see these logs in the sequence sender

[zkevm-node-sequence-sender-001] {"level":"info","ts":1718632391.4257238,"caller":"datacommittee/datacommittee.go:210","msg":"sending request to sign the sequence to 0x5018895310B962aC12b837FAD66e177aC7863Ca5 at http://zkevm-dac-001:8484","pid":6,"version":"0.6.5+cdk"}

I think that’s a good thing since that’s the address for our new DAC member. Now we can see that a sequenced with signatures from the new DAC key: https://sepolia.etherscan.io/tx/0x8d32aa5da27bf41ffeb59cd42369d6c1266dbca357e29411e6c8d01cc088d115

Sequencer Update

At this point, we should be good to try to rotate the sequencer key. The first thing we’ll do is modify the sequencer’s config in order to halt on a specific batch number. The script here will get the current trusted batch number, add 3 to it, and configure the sequencer to halt on that new batch number.

export ETH_RPC_URL="$(kurtosis port print cdk-v1 zkevm-node-rpc-001 http-rpc)"
cur_batch_number=$(cast rpc zkevm_batchNumber | jq -r '.' | sed 's/^0x//' | tr '[:lower:]' '[:upper:]')

Now we can watch the logs of the sequencer to see when the sequencer will halt. At that point we should wait for the verified batch number to catch up. While we wait for that, we can start with some of the sequencer prep. We’ll need a new sequencer and it will need some POL token associated with it.

In my sequencer logs, I now see messages like this:

halting finalizer, error: finalizer reached stop sequencer on batch number: 42

So I think we just need to wait for everything to get finalized. We can use a snippet like this to wait for the verified batch number to catch up. If we’re in a hurry, we can make some tweaks in order to speed up the batch verification process.

export ETH_RPC_URL="$(kurtosis port print cdk-v1 zkevm-node-rpc-001 http-rpc)"
cast rpc zkevm_batchNumber
cast rpc zkevm_virtualBatchNumber
cast rpc zkevm_verifiedBatchNumber
"0x29"
"0x29"
"0x29"

It looks like everything is in sync. Let’s try to modify the sequencer key now.

This transaction updates the trusted sequencer: https://sepolia.etherscan.io/tx/0x9a00fbfa133627d4e7814252d7bfa74fb94c17e925d8949312ab26dc5f51fa36

We previously halted on batch 0xd7f, so we need to make sure that we sequence and verify batches after this number.

I’m seeing errors like this in the sequence sender, so it looks like the DAC doesn’t like something. Let’s just try to restart it for the time being.

Things look better after the restart. It looks like the change in sequencer will require a restart on the DAC.

It looks like we’re able to sequence batches now. This this is the first sequenced batch with the new address: https://sepolia.etherscan.io/tx/0x50c810e6bdc6577eb1fa20289c6a1063f9265697f6543f596b70c5b84b180ab5

The aggregator and agglayer are having some issues now.
