Let the blockchain sync. After the sync is completed, open a new terminal window and login to the server. Then, login as the user node.
axelard keys add broadcaster --home /home/node/.axelar_testnet-2
Give password for the above command and take a backup of the address and the Mnemonic keys and store it a safe location.
axelard keys add validator --home /home/node/.axelar_testnet-2
Give password for the above command and take a backup of the address and the Mnemonic keys and store it a safe location.

mkdir tofnd
cd
tofnd -m create -d /home/node/.axelar_testnet-2/tofnd

Copy the Mnemonic keys and store it in a safe location.
Delete the export file.

Stop the blockchain from the previous terminal window by pressing ctrl+c keys.
You have to create 3 services.
cd /etc/systemd/system
sudo nano axelard.service
Copy the following content into axelard.service and save it.

Reload the daemon and enable to services.
sudo systemctl daemon-reload
sudo systemctl enable axelard
sudo systemctl enable vald
sudo systemctl enable tofnd
Start the services.
sudo systemctl start axelard
sudo systemctl start vald
sudo systemctl start tofnd
Checking the logs.
journalctl -u axelard.service -f -n 100
journalctl -u tofnd.service -f -n 100
journalctl -u vald.service -f -n 100
Get axl tokens from the casablanca faucet - https://faucet-casablanca.testnet.axelar.dev/
Copy paste and execute the following commands 1 line at a time.
sudo kill -9 $(pgrep tofnd)
sudo kill -9 $(pgrep -f "axelard vald-start")
sudo systemctl restart axelard
sudo systemctl restart tofnd
sudo systemctl restart vald

Next step is to register as chain maintainer for EVM chains such as Ethereum. For now, Casablanca testnet supports Ethereum and Avalance. You can install and run your own nodes for Ethereum and Avalance or you can use APIs from 3rd party services such as GetBlock, Infura, Quicknodes, Alchemy. We are using GetBlock as an example.
Open ~/.axelar_testnet-2/config/config.toml file, scroll down to the end, edit the following section. You have to replace <API-KEY> with your respective API keys from GetBlock website.
[[axelar_bridge_evm]]
name = "Ethereum"
rpc_addr = "https://eth.getblock.io/ropsten/?api_key=<API-KEY>"
start-with-bridge = true
[[axelar_bridge_evm]]
name = "Avalanche"
rpc_addr = "https://avax.getblock.io/testnet/ext/bc/C/rpc?api_key=<API-KEY>"
start-with-bridge = true
Save the file and restart all the services.
cd
sudo kill -9 $(pgrep tofnd)
sudo kill -9 $(pgrep -f "axelard vald-start")
sudo systemctl restart axelard
sudo systemctl restart tofnd
sudo systemctl restart vald
Execute the following command to Register as EVM Chain Maintainer.
axelard tx nexus register-chain-maintainer avalanche ethereum --from broadcaster --home /home/node/.axelar_testnet-2 --gas auto --gas-prices 1.5uaxl --gas-adjustment 1.4 --chain-id axelar-testnet-casablanca-1
axelard health-check --tofnd-host localhost --operator-addr $VALIDATOR_OPERATOR_ADDRESS --home /home/node/.axelar_testnet-2
In the following example comamnd, we are delegating 1 AXL tokens to the validator node.
axelard tx staking delegate <validator-operator-address> 1000000uaxl --from validator --home /home/node/.axelar_testnet-2 --gas auto --gas-prices 1.5uaxl --gas-adjustment 1.4 --chain-id axelar-testnet-casablanca-1 -y
axelard query bank balances <axelar-casablanca-address> --chain-id axelar-testnet-casablanca-1
Take a backup of the following files after you have created and registered your validator node successfully.
/home/node/.axelar_testnet-2/config/node_key.json
/home/node/.axelar_testnet-2/config/priv_validator_key.json
/home/node/.axelar_testnet-2/data/priv_validator_state.json
