We install standard updates and requirements

Equipment

Minimum: 2 vCPU 4 RAM Önerilen: 4vCPU 8 RAM

Setup

update

   apt update && apt upgrade -y
   sudo apt install -y curl git jq lz4 build-essential cmake perl automake autoconf libtool wget libssl-dev

go setup

 sudo rm -rf /usr/local/go
 curl -L https://go.dev/dl/go1.22.3.linux-amd64.tar.gz | sudo tar -xzf - -C /usr/local
 echo 'export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin' >> $HOME/.bash_profile
 source .bash_profile

We withdraw the necessary repos

 git clone https://github.com/airchains-network/evm-station.git
 git clone https://github.com/airchains-network/tracks.git

We are starting to set up our evmos network, this is our own network running locally.

    cd evm-station
    go mod tidy

We complete the installation with this command.

    /bin/bash ./scripts/local-setup.sh

RPC will be needed in the next stages, let's set it up.

The RPC section at the bottom will be like this.

     nano ~/.evmosd/config/app.toml

So you learned how to make cosmos rpcs public.

We create an env for the system file to function properly.

    nano ~/.rollup-env

We enter the necessary variables into it.

There is nothing to change in this code block..

 CHAINID="stationevm_9000-1"
 MONIKER="localtestnet"
 KEYRING="test"
 KEYALGO="eth_secp256k1"
 LOGLEVEL="info"
 HOMEDIR="$HOME/.evmosd"
 TRACE=""
 BASEFEE=1000000000
 CONFIG=$HOMEDIR/config/config.toml
 APP_TOML=$HOMEDIR/config/app.toml
 GENESIS=$HOMEDIR/config/genesis.json
 TMP_GENESIS=$HOMEDIR/config/tmp_genesis.json
    VAL_KEY="mykey"

We write the service file. If you are using user, change the root section accordingly.

You can copy paste the entire block with one command, my dears.

sudo tee /etc/systemd/system/rolld.service > /dev/null << EOF
[Unit]
Description=ZK
After=network.target

[Service]
User=root
EnvironmentFile=/root/.rollup-env
ExecStart=/root/evm-station/build/station-evm start --metrics "" --log_level info --json-rpc.api eth,txpool,personal,net,debug,web3 --chain-id stationevm_9000-1
Restart=always
RestartSec=3

[Install]
WantedBy=multi-user.target
EOF

We update and start the services.

  sudo systemctl daemon-reload
  sudo systemctl enable rolld
  sudo systemctl start rolld
  sudo journalctl -u rolld -f --no-hostname -o cat

This command will give us a private key, we keep it.

/bin/bash ./scripts/local-keys.sh

We will use eigenlayer as the DA layer. A key is required for this, we download the binary and allow it to run. There are also celestia and avail installations in the official documentation, you can look at them too. You can also use mock DA (they will allow you to earn points with mock for a while). Currently, DA cannot be changed later on the testnet, they said they will make this possible with the update.

The reason I chose EigenDA is because it is the easiest Celestia and Eigen (the token is also easy to find), we know Celestia by heart - let it be Eigen this time.

cd $HOME
wget https://github.com/airchains-network/tracks/releases/download/v0.0.2/eigenlayer
mkdir -p $HOME/go/bin
chmod +x $HOME/eigenlayer
mv $HOME/eigenlayer $HOME/go/bin

Change WALLANAME and keep the ECDSA Private Key given to you in the output.

Close it with Ctrl+c, enter and note the other public hex given, you will need it.

Add 0.5 eth to the given 0x evm address on the holesky network, just in case.

 eigenlayer operator keys create --key-type ecdsa CUZDANADI

Now we move on to the track and station part.

cd $HOME
cd tracks
go mod tidy

While in the tracks folder, we start the following code. PUBLICHEX will be the public key we just received.

You can change the MONIKER (validator name) as per your preference.

 go run cmd/main.go init --daRpc "disperser-holesky.eigenda.xyz" --daKey "PUBLICHEX" --daType "eigen" --moniker "MONIKER" --stationRpc "http://127.0.0.1:8545" --stationAPI 
 "http://127.0.0.1:8545" --stationType "evm"

Now we create the tracker address. Replace from TRACKERCUZ.

Back up the output, buy tokens from the switchyard faucet channel on discord with an air prefix wallet.

  go run cmd/main.go keys junction --accountName TRACKERCUZDAN --accountPath $HOME/.tracks/junction-accounts/keys

Then we run the prover.

 go run cmd/main.go prover v1EVM

Now we need node id, we get it from here.

You can search for node id with ctrl w, go to the bottom and go a little higher

nano ~/.tracks/config/sequencer.toml

In the code below

The name you wrote above from TRACKERCUZ TRACKERCUZDAN-ADDRESS also air wallet your ip ip address NODEID will be the node id we obtained from sequencer.toml.

 go run cmd/main.go create-station --accountName TRACKERCUZDAN --accountPath $HOME/.tracks/junction-accounts/keys --jsonRPC "https://airchains-testnet-rpc.cosmonautstakes.com/" -- 
 info "EVM Track" --tracks TRACKERCUZDAN-ADRESI --bootstrapNode "/ip4/IP/tcp/2300/p2p/NODEID"

We've set up the station, now let's run it with the service.

Those who do not want to run the service can open a screen and run the go run cmd/main.go start command in the tracks folder.

sudo tee /etc/systemd/system/stationd.service > /dev/null << EOF [Unit] Description=station track service After=network-online.target [Service] User=root WorkingDirectory=/root/tracks/ ExecStart=/usr/local/go/bin/go run cmd/main.go start Restart=always RestartSec=3 LimitNOFILE=65535 [Install] WantedBy=multi-user.target EOF

and

   sudo systemctl daemon-reload
   sudo systemctl enable stationd
   sudo systemctl restart stationd
   sudo journalctl -u stationd -f --no-hostname -o cat

Is the installation ok?

That's all the installation process. But you don't earn points right now. We import the mnemonics of your Tracker wallet into leap wallet and click https://points.airchains.io/ connect. You can see your station and points on the Dashboard. Since we have not made a tx yet, 100 points pending will appear. The reason for this is that you need to take out pods to earn points. You can think of it as a package consisting of pod 25tx. Every 25tx will extract 1 pod and you will earn 5 points from these transactions. The 100 points in the first installation will be active after the first pod. For this, we do the following. First, we got a priv key with the bin/bash ./scripts/local-keys.sh command and set the rpc. We import this priv key to Metamaska, in the add network section

rpc http://IP:8545

id 9000

ticker tEVMOS

We enter and okay.

From here, it's up to you whether you deploy a contract or a manual TX.

Those who get an rpc error during the track process should try rollback. Sometimes the problem is solved with 1, sometimes 3 rollback operations. Run the go run cmd/main.go rollback command as many times as you want to rollback, waiting for the output each time..

systemctl stop stationd cd tracks git pull go run cmd/main.go rollback sudo systemctl restart stationd sudo journalctl -u stationd -f --no-hostname -o cat

Come on, goodbyee
