Configure RPC & Setup Variable

Configure RPC

Edit your app.toml

nano ~/.evmosd/config/app.toml

Change 127.0.0.1 to 0.0.0.0 like this image below

Setup Variables

We are creating an environment for the system file to function properly.

nano ~/.rollup-env

There is nothing to change ın the code block here.

Start Service rolld (please copy one by one for this)

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, which we should store securely. (save to your notepad)

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

We will use Avail Turing as the DA layer. You can also use a mock DA (mock will allow earning points for a period of time). Currently, on the testnet, the DA cannot be changed later, but they said they will make this possible with an update.

cd $HOME
git clone https://github.com/availproject/availup.git
cd availup
/bin/bash availup.sh --network "turing" --app_id 36

Close with Ctrl+c, press Enter

Inside the file ~/.avail/identity/identity.toml, you will find the Mnemonics of your Avail wallet. Copy and store these words. Close with Ctrl+c, press Enter, and make a note of the other Avail-Mnemonics given as they will be needed. Add the copied Mnemonics to Polkadot.js or Talisman wallet get your wallet address on the Avail Turing network and receive tokens from the faucet.

We are now moving on to the track and station section.

cd $HOME
cd tracks
go mod tidy

Change <Avail-Wallet-Adress> and <moniker-name>

go run cmd/main.go init --daRpc "http://127.0.0.1:7000" --daKey "<Avail-Wallet-Adress>" --daType "avail" --moniker "<moniker-name>" --stationRpc "http://127.0.0.1:8545" --stationAPI "http://127.0.0.1:8545" --stationType "evm"

output will like this

Now we are creating a tracker address. Please replace <moniker-name>.

go run cmd/main.go keys junction --accountName <moniker-name> --accountPath $HOME/.tracks/junction-accounts/keys

output will like this

Run Prover

go run cmd/main.go prover v1EVM

Now , Search Your NODE ID

You can search for the node id with, go to the bottom, and scroll up a bit.

nano ~/.tracks/config/sequencer.toml

Prepare some preparations for this part and prepare the following command. SERVER(VPS) IP <IP> Get nodeid> in the nano ~/.tracks/config/sequencer.toml file Enter the AIRCHAIN wallet address you created before <WALLET_ADDRESS> Enter the validator name <moniker-name>

go run cmd/main.go create-station --accountName <moniker-name> --accountPath $HOME/.tracks/junction-accounts/keys --jsonRPC "https://airchains-testnet-rpc.cosmonautstakes.com/" --info "EVM Track" --tracks <WALLET_ADDRESS> --bootstrapNode "/ip4/<IP>/tcp/2300/p2p/<node_id>"

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