[Native Mode] Guide to the Redstone Update and the Merge
This guide will cover everything you need to know in order to prepare your node for the Redstone Update and The Merge if you are using Native Mode.
Things to Do Before Upgrading to v1.5.0
Before upgrading to v1.5.0 and higher of the Smartnode, please go through the following checklist to make sure you're prepared:
Switch to a Full Execution Client
The Merge requires you to run your own Execution client, so you won't be able to use remote providers like Infura or Pocket anymore.
Because of this change, if you're currently using a light Execution client, you should switch to a full client while you're still on v1.4, let it sync to completion, and then upgrade to v1.5.
Set Up the Engine API
The Merge changes the way your Execution client talks to your Consensus client. Instead of using the old HTTP or Websocket based RPC system, The Merge requires a new system exposed by your Execution client called the Engine API.
This is a special connection that lets the Consensus client replace the old Proof-of-Work mining system with Proof-of-Stake; it's the heart of The Merge. It's also authenticated with a secret token, so only your Consensus client can connect to your Execution client - nothing else can.
As you manage your own Execution and Consensus clients, you'll need to set up the Engine API manually. How to do it depends entirely on which clients you're running.
CoinCashew has a great and concise guide on how to set up the Engine API on your Execution and Consensus clients. Give that a look, and test the new configuration out by making sure it still attests properly before upgrading.
We'll show you how to set up your Validator client so that it uses the correct fee recipient required by the Smartnode software automatically below.
Upgrading to v1.5.0
Upgrading the Smartnode stack to v1.5.0 is no different than any other upgrade. Simply follow the normal directions here.
Things You Should Do After Upgrading
In Native mode, there are several things you will need to do manually after upgrading:
Ensure a Successful Upgrade
The first thing to do is ensure that your node is working correctly. Consider taking the following steps:
- Check your log scripts for the Execution client, the Consensus client, the Validator client, and the Smartnode daemon (the
rp-nodeservice) to ensure they're all functioning normally without errors.
- Confirm with a Block Explorer (such as your Grafana dashboard and https://beaconcha.in) that you are still attesting properly
- Remember that if you have Doppelganger protection enabled, you will miss a few attestations after the restart. This is normal!
Set up the Fee Recipient in your Validator Client
One of the critical details to set up prior to the Merge is the fee recipient specified by your validator client. As described in the overview article, this can be one of two values:
- If you are opted into the Smoothing Pool, this must be the address of the Smoothing Pool contract. You can get the address from the official contracts page.
- If you are not in the Smoothing Pool, this must be the address of your node's fee distributor contract. You can get the address by running
rocketpool node status, under the
Fee Distributor and Smoothing Poolsection.
In Native mode, you have the choice of letting the Smartnode manage this for you if you use the Smartnode daemon service,
rp-node, or managing it yourself if you do not use the daemon.
Automatic Management via the Daemon
The Smartnode daemon will automatically determine the appropriate fee recipient for your node and manage it in case it changes (such as opting into and out of the Smoothing Pool). This is the safest option, because the Smartnode will always ensure it's set to a value that prevents penalization.
The way it does this is by maintaining a file with the correct fee recipient in it, and regularly refreshing it to ensure its correctness. When it needs to be updated, it modifies the file and restarts your Validator client automatically so it loads the new recipient - similarly to how it restarts your Validator client after staking a new minipool.
Select your client below to learn how to set it up:
Modify your Validator Client service by adding the following line before the
Next, add the following command line argument to the end of your
Your VC will now use the file managed by the Smartnode daemon, and will automatically be restarted whenever the fee recipient changes. :::::
Manual Fee Recipient Management
By doing this, you assume full responsibility for ensuring your fee recipient is always set to the correct address.
Please read the penalty specification to understand what it must be set to given your configuration, and when you can safely change it from one value to another.
Failure to do so could result in your minipools being penalized!
Prior to Redstone being deployed, you can simply use the rETH address for the network you're on (which can be found in the official contracts page). The rETH address is always safe no matter what.
Once Redstone has been deployed, you can see the exact address that you should set your fee recipient to via
rocketpool node status. For example, if you are opted into the Smoothing Pool, it will show the Smoothing Pool's address and note that you must use it as your fee recipient:
If you are not opted into the Smoothing Pool, it will show your fee distributor address and note that you must use it as your fee recipient:
Select your Consensus client below to learn how to configure it.
Add the following command line argument to your Validator Client's service definition file:
- The rETH address before the Redstone update is deployed (e.g.,
- Your node's fee distributor after Redstone is deployed, which you can retrieve with
rocketpool node statusonce the contract upgrade occurs
- The Smoothing Pool address if you opt into the Smoothing Pool
As a reminder,
rocketpool node status will show you the correct fee recipient to use at any time.
Please read the penalty specification carefully to understand the conditions and expectations around the fee recipient. :::::
Set Up MEV-Boost
MEV-boost is the system Flashbots provides to give MEV rewards to Proof-of-Stake validators after The Merge.
Rocket Pool requires all nodes to use it to maximize their returns and thus keep the protocol competitive with other staking services.
You will need to make some adjustments to your Beacon Node / Consensus client to connect it to MEV-boost.
MEV-boost is currently not available on Holesky or Mainnet, so you do not need to set it up at this time. Of course, you will not be penalized for not using it during this transition period.
Once it becomes available, we will announce a date at which it must be installed and connected to your node. Flashbots will provide instructions you can follow at that time, and we will link to them here.
Once we make the announcement that MEV-boost must be enabled by all node operators, you must ensure you have it properly installed and configured with your Beacon Node!
Not doing so will result in your minipool being penalized.
Set Up a Fallback Node
Because The Merge is not compatible with remote providers like Infura and Pocket, you'll lose the ability to use them as fallback Execution clients when your primary goes offline.
The Smartnode still has the ability to provide a fallback Execution client (and now a fallback Consensus client as well), but you will now need to use Execution and Consensus clients that you control.
For more information on setting up a fallback node, see the Fallback node guide.
Initialize your Fee Distributor
If you aren't planning to opt into the Smoothing Pool and claim all of your priority fees and MEV rewards to your fee distributor contract, you will eventually have to initialize it (create the contract instance on the chain) in order to claim rewards from it to your withdrawal address.
This is a fairly cheap operation and only needs to be done once.
Initializing your fee distributor can be done at any time. You can let rewards accumulate in its address long before you initialize it, and your balance will remain after initialization.
We recommend you do so when gas prices are low to minimize the overhead cost.
Note that it must be initialized in order to claim your rewards.
Opt Into the Smoothing Pool
If you plan on taking advantage of the Smoothing Pool right away, you should opt in before the end of the first Redstone rewards period to maximize your "eligibility" amount.
Opting in can be done via running the following command:
rocketpool node join-smoothing-pool
The Redstone upgrade replaces the expensive, problematic old rewards system with a brand new one that's much cheaper, supports automatic restaking of RPL (both partial and full amounts), and - most importantly - lets you claim your rewards whenever you want.
Because there is no longer a time limit on claiming rewards, and because it's cheaper to claim many rewards intervals at once, the automatic rewards claiming feature of the Smartnode has been removed. You will now be able to claim rewards via the following command:
rocketpool node claim-rewards
This will show you all of the rewards you've accumulated across all of the rewards intervals starting with the Redstone upgrade.
