DAppNode Package for MEV Plus on Holesky

This package allows Dappnode solo stakers to natively delegate their stake and earn restaking ETH rewards on Holesky.

Native delegation makes the Ethereum stake available on the Ethereum execution layer smart contract and therefore the native delegation process will require GAS to register validators from the node and do the stake delegation which is then tracked by the Ethereum execution layer.

For more information about the MEV Plus module take a look at the docs: https://docs.restaking.cloud/middleware/mevPlusModule

Please see the above doc if EXTRA_OPTS in the MEV Plus DAppNode Package config are required to control which validators are natively delegated and which are not. By default, all of the validators on the node will be natively delegated.

Installation and setup wizzard

The MEV Plus Holesky DAppNode package can be found by searching the public package repo but can alternatively be downloaded via the following link:

http://my.dappnode/installer/public/mev-plus-holesky.public.dappnode.eth

Installation may require by passing signing restrictions as per above screenshot.

Once the installation starts the setup wizard will guide in adding the Ethereum wallet that will pay for GAS:

If required to adjust the MEV Plus config to add any additional flags such as the inclusion list, please make those adjustments at this stage.

Updating the beacon node

We will use the lighthouse as an example for how to configure your beacon node.

Lets enter Packages -> Lighthouse Holesky -> Config -> Show Advanced Editor

_DAPPNODE_GLOBAL_MEVBOOST_HOLESKY will need to be adjusted to false on the Beacon chain node only.

In the EXTRA_OPTS section of Lighthouse Beacon Chain, we need to inject the following:

--builder http://mev-plus-holesky.public.dappnode:18551

We need to proceed to restart MEV Plus (and potentially the consensus node) and then watch native delegation take place. The MEV Plus logs will look like this when interacting with a node that is not yet synced:

And the MEV Plus logs will look like this when the node is synced and operational:

And finally if native delegation is taking place the following logs can be observed:

Enabling Preferred Node Operator (PNO) Module

In order to enable PNO, we need to update the MEV Plus EXTRA_OPTS setting:

Lets enter Packages -> Mev Plus Holesky -> Config -> Show Advanced Editor

where we need to add the following to the EXTRA_OPTS setting:

-pno.eth1-private-key 1234567890abcdef1234567890abcdef12345f -pno.beacon-node-url <beacon_node> -pno.execution-node-url <execution_node> -pno.auto-redelegate

-pno.eth1-private-key is the private key that will pay for GAS for manage PNO status and liqid delegations.
