Pell Node Setup Guide

1. Install Dependencies

Run the following commands to update your system and install necessary dependencies:

shCopyEditsudo apt update && sudo apt upgrade -y
sudo apt install curl git wget htop tmux build-essential jq make lz4 gcc unzip -y

2. Install Go

shCopyEditcd $HOME
VER="1.22.3"
wget "https://golang.org/dl/go$VER.linux-amd64.tar.gz"
sudo rm -rf /usr/local/go
sudo tar -C /usr/local -xzf "go$VER.linux-amd64.tar.gz"
rm "go$VER.linux-amd64.tar.gz"
echo "export PATH=$PATH:/usr/local/go/bin:~/go/bin" >> ~/.bash_profile
source $HOME/.bash_profile
mkdir -p ~/go/bin

3. Set Environment Variables

shCopyEditecho "export WALLET="wallet"" >> $HOME/.bash_profile
echo "export MONIKER="test"" >> $HOME/.bash_profile
echo "export PELL_CHAIN_ID="ignite_186-1"" >> $HOME/.bash_profile
echo "export PELL_PORT="58"" >> $HOME/.bash_profile
source $HOME/.bash_profile

4. Download Binary and WASMVM

shCopyEditcd $HOME
wget -O pellcored https://github.com/0xPellNetwork/network-config/releases/download/v1.2.1/pellcored-v1.2.1-linux-amd64
chmod +x pellcored
mv pellcored ~/go/bin/

WASMVM_VERSION=v2.1.2
export LD_LIBRARY_PATH=~/.pellcored/lib
mkdir -p $LD_LIBRARY_PATH
wget "https://github.com/CosmWasm/wasmvm/releases/download/$WASMVM_VERSION/libwasmvm.$(uname -m).so" -O "$LD_LIBRARY_PATH/libwasmvm.$(uname -m).so"
echo "export LD_LIBRARY_PATH=$HOME/.pellcored/lib:$LD_LIBRARY_PATH" >> ~/.bash_profile
source ~/.bash_profile

5. Configure and Initialize Node

shCopyEditpellcored config node tcp://localhost:${PELL_PORT}657
pellcored config keyring-backend os
pellcored config chain-id ignite_186-1
pellcored init "test" --chain-id ignite_186-1

6. Download Genesis and Addrbook

shCopyEditwget -O $HOME/.pellcored/config/genesis.json https://server-5.itrocket.net/testnet/pell/genesis.json
wget -O $HOME/.pellcored/config/addrbook.json https://server-5.itrocket.net/testnet/pell/addrbook.json

7. Set Seeds and Peers

shCopyEditSEEDS="[e-mail]:58656"
PEERS="[e-mail]:58656,28c0fcd184c31ac7f3e2b3a91ae60dedc086b0c3@94.130.204.227:26656,1189d15c84a5b79a95cdf0cc65d007c6aa85b66d@49.12.82.124:26656,f9decf3cb78d88581d6c3c14828cb906a75fd060@95.216.97.238:26656,32fac46251436c7bee07b9aa5571f69b5fb765f4@193.34.212.164:57656"

sed -i -e "/^\[p2p\]/,/^\[/{s/^[[:space:]]*seeds *=.*/seeds = \"$SEEDS\"/}" \
       -e "/^\[p2p\]/,/^\[/{s/^[[:space:]]*persistent_peers *=.*/persistent_peers = \"$PEERS\"/}" $HOME/.pellcored/config/config.toml

8. Configure Custom Ports

shCopyEditsed -i.bak -e "s%:1317%:${PELL_PORT}317%g;
s%:8080%:${PELL_PORT}080%g;
s%:9090%:${PELL_PORT}090%g;
s%:9091%:${PELL_PORT}091%g;
s%:8545%:${PELL_PORT}545%g;
s%:6065%:${PELL_PORT}065%g" $HOME/.pellcored/config/app.toml

9. Set Pruning and Gas Price

shCopyEditsed -i -e "s/^pruning *=.*/pruning = \"custom\"/" $HOME/.pellcored/config/app.toml 
sed -i -e "s/^pruning-keep-recent *=.*/pruning-keep-recent = \"100\"/" $HOME/.pellcored/config/app.toml
sed -i 's|minimum-gas-prices =.*|minimum-gas-prices = "0apell"|g' $HOME/.pellcored/config/app.toml

10. Create and Start System Service

shCopyEditsudo tee /etc/systemd/system/pellcored.service > /dev/null <<EOF
[Unit]
Description=Pell Node
After=network-online.target
[Service]
User=$USER
WorkingDirectory=$HOME/.pellcored
ExecStart=$(which pellcored) start --home $HOME/.pellcored
Environment=LD_LIBRARY_PATH=$HOME/.pellcored/lib/
Restart=on-failure
RestartSec=5
LimitNOFILE=65535
[Install]
WantedBy=multi-user.target
EOF

sudo systemctl daemon-reload
sudo systemctl enable pellcored
sudo systemctl restart pellcored
sudo journalctl -u pellcored -fo cat

11. Check Sync Status

shCopyEditpellcored status 2>&1 | jq

12. Create Wallet

shCopyEditpellcored keys add $WALLET
pellcored keys add $WALLET --recover  # Restore wallet

13. Save Wallet and Validator Address

shCopyEditWALLET_ADDRESS=$(pellcored keys show $WALLET -a)
VALOPER_ADDRESS=$(pellcored 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

14. Create Validator

shCopyEditcd $HOME
echo "{\"pubkey\":{\"@type\":\"/cosmos.crypto.ed25519.PubKey\",\"key\":\"$(pellcored comet show-validator | grep -Po '\"key\":\s*\"\K[^"]*')\"},
    \"amount\": \"1000000apell\",
    \"moniker\": \"test\",
    \"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

pellcored tx staking create-validator validator.json \
    --from $WALLET \
    --chain-id ignite_186-1 \
    --fees 30apell --gas 300000

15. Security & Firewall

shCopyEditsudo ufw default allow outgoing 
sudo ufw default deny incoming 
sudo ufw allow ssh/tcp 
sudo ufw allow ${PELL_PORT}656/tcp
sudo ufw enable

16. Delete Node

shCopyEditsudo systemctl stop pellcored
sudo systemctl disable pellcored
sudo rm -rf /etc/systemd/system/pellcored.service
sudo rm $(which pellcored)
sudo rm -rf $HOME/.pellcored
sed -i "/PELL_/d" $HOME/.bash_profile
