Create Service File

sudo tee /etc/systemd/system/paxid.service > /dev/null <<EOF
[Unit]
Description=paxi
After=network-online.target
[Service]
User=$USER
ExecStart=$(which paxid) start
Restart=on-failure
RestartSec=3
LimitNOFILE=65535
[Install]
WantedBy=multi-user.target
EOF

---

Start Service

sudo systemctl daemon-reload
sudo systemctl enable paxid
sudo systemctl start paxid && sudo journalctl -u paxid -fo cat

---

Install Wasm Sync

bash <(curl -s https://raw.githubusercontent.com/kyronode/all-about-cosmos/refs/heads/main/Mainnet/Paxi/wasm.sh)
sudo systemctl restart paxid

---

Snapshot

sudo apt install lz4 -y
sudo systemctl stop paxid
cp ~/go/bin/paxi/data/priv_validator_state.json ~/go/bin/paxi/priv_validator_state.json.backup
paxid tendermint unsafe-reset-all --home ~/go/bin/paxi --keep-addr-book

mv ~/go/bin/paxi/priv_validator_state.json.backup ~/go/bin/paxi/data/priv_validator_state.json
sudo systemctl restart paxid && sudo journalctl -u paxid -fo cat

---

Node Synchronize Checker

# Paste this to your terminal
bash <(curl -s https://raw.githubusercontent.com/kyronode/all-about-cosmos/refs/heads/main/Mainnet/Paxi/paxi-sync.sh)

---

Create or Restore Wallet

Create new wallet and save ur mnemonics securely

paxid keys add $WALLET

If u want to restore use this command

paxid keys add $WALLET --recover

Set keys variable enviroment

WALLET_ADDRESS=$(paxid keys show $WALLET -a)
VALOPER_ADDRESS=$(paxid 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

---

Create Validator

If ur node has been fully synchronized, then u can create ur validator: Please Change <YOUR_MONIKER><YOUR_IDENTITY><YOUR_WEBSITE><YOUR_DETAILS> with ur own.

cd $HOME
echo "{
  \"pubkey\": {\"@type\":\"/cosmos.crypto.ed25519.PubKey\",\"key\": \"$(paxid tendermint show-validator | grep -Po '\"key\":\s*\"\K[^\"]*')\"},
  \"amount\": \"1000000upaxi\",
  \"moniker\": \"<YOUR_MONIKER>\",
  \"identity\": \"<YOUR_IDENTITY>\",
  \"website\": \"<YOUR_WEBSITE>\",
  \"security\": \"\",
  \"details\": \"<YOUR_DETAILS>\",
  \"commission-rate\": \"0.05\",
  \"commission-max-rate\": \"0.25\",
  \"commission-max-change-rate\": \"0.1\",
  \"min-self-delegation\": \"1\"
}" > validator.json

# Create a validator using the JSON configuration
paxid tx staking create-validator validator.json \
    --from $WALLET \
    --chain-id paxi-mainnet \
    --fees 15000upaxi \
    --gas-adjustment 1.3 \
    --gas auto \
    -y

---

Delete Node

Please backup ur wallet and important file like "priv_validator_key.json" before deleting.

sudo systemctl stop paxid
sudo systemctl disable paxid
sudo systemctl daemon-reload
sudo rm -rf /etc/systemd/system/paxid.service
sudo rm $(which paxid)
sudo rm -rf ~/go/bin/paxi/
