sed -i -e "s/^seeds *=.*/seeds = \"$SEEDS\"/; s/^persistent_peers *=.*/persistent_peers = \"$PEERS\"/" $HOME/.junction/config/config.toml

8. Set custom ports in app.toml:

sed -i.bak -e "s%:1317%:${AIRCHAIN_PORT}317%g;
s%:8080%:${AIRCHAIN_PORT}080%g;
s%:9090%:${AIRCHAIN_PORT}090%g;
s%:9091%:${AIRCHAIN_PORT}091%g;
s%:8545%:${AIRCHAIN_PORT}545%g;
s%:8546%:${AIRCHAIN_PORT}546%g;
s%:6065%:${AIRCHAIN_PORT}065%g" $HOME/.junction/config/app.toml

9. Set custom ports in config.toml file:

sed -i.bak -e "s%:26658%:${AIRCHAIN_PORT}658%g;
s%:26657%:${AIRCHAIN_PORT}657%g;
s%:6060%:${AIRCHAIN_PORT}060%g;
s%:26656%:${AIRCHAIN_PORT}656%g;
s%^external_address = \"\"%external_address = \"$(wget -qO- eth0.me):${AIRCHAIN_PORT}656\"%;
s%:26660%:${AIRCHAIN_PORT}660%g" $HOME/.junction/config/config.toml

10. Config pruning:

sed -i -e "s/^pruning *=.*/pruning = \"custom\"/" $HOME/.junction/config/app.toml
sed -i -e "s/^pruning-keep-recent *=.*/pruning-keep-recent = \"100\"/" $HOME/.junction/config/app.toml
sed -i -e "s/^pruning-interval *=.*/pruning-interval = \"50\"/" $HOME/.junction/config/app.toml

11. Set minimum gas price, enable prometheus and disable indexing:

sed -i 's|minimum-gas-prices =.*|minimum-gas-prices = "0.001amf"|g' $HOME/.junction/config/app.toml
sed -i -e "s/prometheus = false/prometheus = true/" $HOME/.junction/config/config.toml
sed -i -e "s/^indexer *=.*/indexer = \"null\"/" $HOME/.junction/config/config.toml

12. Create service file:

sudo tee /etc/systemd/system/junctiond.service > /dev/null <<EOF
[Unit]
Description=Airchains node
After=network-online.target
[Service]
User=$USER
WorkingDirectory=$HOME/.junction
ExecStart=$(which junctiond) start --home $HOME/.junction
Restart=on-failure
RestartSec=5
LimitNOFILE=65535
[Install]
WantedBy=multi-user.target
EOF

13. Reset and download snapshot:

junctiond tendermint unsafe-reset-all --home $HOME/.junction
if curl -s --head curl https://testnet-files.itrocket.net/airchains/snap_airchains.tar.lz4 | head -n 1 | grep "200" > /dev/null; then
  curl https://testnet-files.itrocket.net/airchains/snap_airchains.tar.lz4 | lz4 -dc - | tar -xf - -C $HOME/.junction
    else
  echo no have snap
fi

14. Enable and start service:

sudo systemctl daemon-reload
sudo systemctl enable junctiond
sudo systemctl restart junctiond && sudo journalctl -u junctiond -f

15.Check sync status:

junctiond status 2>&1 | jq 

*Once your node is fully synced, the output from above will print "false"

16. Creat Wallet/ Restore wallet:

junctiond keys add $WALLET

*Don’t forget to save the mnemonic

junctiond keys add $WALLET --recover

Save wallet and validator addres:

WALLET_ADDRESS=$(junctiond keys show $WALLET -a)
VALOPER_ADDRESS=$(junctiond keys show $WALLET --bech val -a)
echo "export WALLET_ADDRESS="$WALLET_ADDRESS >> $HOME/.bash_profile
echo "export VALOPER_ADDRESS="$VALOPER_ADDRESS >> $HOME/.bash_profile
source $HOME/.bash_profile

17. Faucet token: https://discord.com/invite/airchains

Join Discord Server and use Faucet bot

18. Create validator.json file:

cd $HOME
echo "{\"pubkey\":{\"@type\":\"/cosmos.crypto.ed25519.PubKey\",\"key\":\"$(junctiond comet show-validator | grep -Po '\"key\":\s*\"\K[^"]*')\"},
    \"amount\": \"1000000amf\",
    \"moniker\": \"Node_name\",
    \"identity\": \"\",
    \"website\": \"\",
    \"security\": \"\",
    \"details\": \"I love blockchain ❤️\",
    \"commission-rate\": \"0.1\",
    \"commission-max-rate\": \"0.2\",
    \"commission-max-change-rate\": \"0.01\",
    \"min-self-delegation\": \"1\"
}" > validator.json

19. Create a validator using the JSON configuration:

junctiond tx staking create-validator validator.json \
    --from "wallet_name" \
    --chain-id junction \
	--fees 200amf \

Delegate:

junctiond tx staking delegate "Validator_address" "amount"amf --from "wallet_name" --chain-id junction --fees 200amf -y

Send token:

junctiond tx bank send "from_address" "to_address" "amount"amf --chain-id junction --fees 200amf -y
