Testing

All of these steps are for Ubuntu 22.04.

If you want to contribute with guides and testing, please open an issue.

Make sure that you are only using test ether, test accounts and test passwords. Do not reuse anything from your real accounts. When in doubt, please ask.

We will add instructions for more consensus clients as they complete the Builder API implementation. Look at the consensus clients implementation status.

Let's start...

Make a workspace directory:

mkdir -p ~/workspace/
cd ~/workspace/

sudo apt install git

Get the testnet configuration:

git clone https://github.com/eth-clients/merge-testnets

Generate a secret:

openssl rand -hex 32 | tr -d "\n" > ~/workspace/secret

Get the key generator:

cd ~/workspace
wget https://github.com/ethereum/staking-deposit-cli/releases/download/v2.2.0/staking_deposit-cli-9ab0b05-linux-amd64.tar.gz
tar xvf staking_deposit-cli-9ab0b05-linux-amd64.tar.gz

Install metamask.

Register as a validator

In kiln

Get kiln test ether. See Where to get test ether?
Add the kiln network to metamask with the following parameters:

Network Name: Kiln
New RPC URL: https://rpc.kiln.themerge.dev/
Chain ID: 1337802
Currenty Symbol: ETH
Block Explorer: https://explorer.kiln.themerge.dev/

Create your validator keys:

cd ~/workspace/staking_deposit-cli-9ab0b05-linux-amd64/
./deposit new-mnemonic --num_validators 1 --chain kiln
mv validator_keys validator_keys-kiln

Go to the kiln launchpad and follow the instructions to become a validator: https://kiln.launchpad.ethereum.org/en/

In ropsten

Get ropsten test ether. See Where to get test ether?
Connect your metamast to the ropsten network.
Create your validator keys:

cd ~/workspace/staking_deposit-cli-9ab0b05-linux-amd64/
./deposit new-mnemonic --num_validators 1 --chain ropsten
mv validator_keys validator_keys-ropsten

Go to the ropsten launchpad and follow the instructions to become a validator: https://ropsten.launchpad.ethereum.org/en/

Teku

Last verified: 2022-07-19

Status: https://github.com/flashbots/mev-boost/issues/156

Known issues:

https://github.com/ConsenSys/teku/issues/5885

Install java:

sudo apt install default-jre

Get the source code and compile:

cd ~/workspace
git clone https://github.com/ConsenSys/teku
cd teku
./gradlew installDist

Prepare the validator keys. These are the keys created when you registered your validator. Teku requires you to put the password to the validator keys in a .txt file with the same name as the keystore. And then, to pass the paths as parameters as shown below, replacing <path-to-keystore.json>:<path-to-password.txt> with your paths.

More details: https://docs.teku.consensys.net/en/latest/Reference/CLI/CLI-Syntax/#validator-keys

Also note to replace with the address of your test account for validators-proposer-default-fee-recipient in order to earn test rewards.

Run the validator and beacon nodes in kiln:

./build/install/teku/bin/teku \
  --data-path "datadir-teku-kiln" \
  --network kiln \
