# Set your node's moniker (choose a unique name)
export MONIKER="your-node-name"

Step 2: initialize the node

Mainnet
Testnet

# Initialize with the mainnet chain ID
stabled init $MONIKER --chain-id stable_988-1

# This creates the configuration directory at ~/.stabled/

Note: For current network parameters including chain ID, see Mainnet Information

# Initialize with the testnet chain ID
stabled init $MONIKER --chain-id stabletestnet_2201-1

# This creates the configuration directory at ~/.stabled/

Note: For current network parameters including chain ID, see Testnet Information

Step 3: download genesis file

Mainnet
Testnet

# Create backup of default genesis
mv ~/.stabled/config/genesis.json ~/.stabled/config/genesis.json.backup

# Download mainnet genesis
wget https://stable-data-dist.s3.us-east-1.amazonaws.com/mainnet/configuration/genesis.zip
unzip genesis.zip

# Move genesis to config directory
cp genesis.json ~/.stabled/config/genesis.json

# Verify genesis checksum
sha256sum ~/.stabled/config/genesis.json
# Expected: e1ceda79a3cc48a1028ca8646a2e9e2d156f610637cfb8b428ca8354277921f1

# Create backup of default genesis
mv ~/.stabled/config/genesis.json ~/.stabled/config/genesis.json.backup

# Download testnet genesis
wget https://stable-data-dist.s3.us-east-1.amazonaws.com/testnet/configuration/genesis.zip
unzip genesis.zip

# Move genesis to config directory
cp genesis.json ~/.stabled/config/genesis.json

# Verify genesis checksum
sha256sum ~/.stabled/config/genesis.json
# Expected: 66afbb6e57e6faf019b3021de299125cddab61d433f28894db751252f5b8eaf2

Step 4: configure node

Download configuration files

Mainnet

# Download optimized configuration (choose one based on your node type)
# For RPC/Full nodes:
wget https://stable-data-dist.s3.us-east-1.amazonaws.com/mainnet/configuration/rpc_node_config.zip
unzip rpc_node_config.zip

# For Archive nodes:
# wget https://stable-data-dist.s3.us-east-1.amazonaws.com/mainnet/configuration/archive_node_config.zip
# unzip archive_node_config.zip

# Backup original config
cp ~/.stabled/config/config.toml ~/.stabled/config/config.toml.backup

# Apply new configuration
cp config.toml ~/.stabled/config/config.toml

# Update moniker in config
sed -i "s/^moniker = \".*\"/moniker = \"$MONIKER\"/" ~/.stabled/config/config.toml

# Download optimized configuration
wget https://stable-data-dist.s3.us-east-1.amazonaws.com/testnet/configuration/rpc_node_config.zip
unzip rpc_node_config.zip

# Backup original config
cp ~/.stabled/config/config.toml ~/.stabled/config/config.toml.backup

# Apply new configuration
cp config.toml ~/.stabled/config/config.toml

# Update moniker in config
sed -i "s/^moniker = \".*\"/moniker = \"$MONIKER\"/" ~/.stabled/config/config.toml

Essential configuration updates

Edit ~/.stabled/config/app.toml:

# Enable JSON-RPC for EVM compatibility
[json-rpc]
enable = true
address = "0.0.0.0:8545"
ws-address = "0.0.0.0:8546"
allow-unprotected-txs = true

Edit ~/.stabled/config/config.toml:

Mainnet
Testnet

# P2P Configuration
[p2p]
# Maximum number of peers
max_num_inbound_peers = 50
max_num_outbound_peers = 30

# Seed nodes
seeds = "9aa181b20248e948567cb47a15eae35d58cd549d@seed1.stable.xyz:46656"

# Persistent peers (mainnet seed nodes)
persistent_peers = "b896f6f8ca5a4d1cc40de09407df0c96e76df950@peer1.stable.xyz:26656"

# Enable peer exchange
pex = true

# RPC Configuration
[rpc]
# Listen address
laddr = "tcp://0.0.0.0:26657"

# Maximum number of simultaneous connections
max_open_connections = 900

# CORS settings (adjust for production)
cors_allowed_origins = ["*"]

# P2P Configuration
[p2p]
# Maximum number of peers
max_num_inbound_peers = 50
max_num_outbound_peers = 30

# Seed nodes
seeds = "6f3195823f7e5ee6f911a0a0ceb9ea689e0dc5bd@seed1.testnet.stable.xyz:56656"

# Persistent peers (testnet seed nodes)
persistent_peers = "128accd3e8ee379bfdf54560c21345451c7048c7@peer1.testnet.stable.xyz:26656"

# Enable peer exchange
pex = true

# RPC Configuration
[rpc]
# Listen address
laddr = "tcp://0.0.0.0:26657"

# Maximum number of simultaneous connections
max_open_connections = 900

# CORS settings (adjust for production)
cors_allowed_origins = ["*"]

Systemd service setup

Create a systemd service for automatic management:

Step 1: create service file

Mainnet
Testnet

sudo tee /etc/systemd/system/stabled.service > /dev/null <<EOF
[Unit]
Description=Stable Daemon Service
After=network-online.target

[Service]
User=$USER
ExecStart=/usr/bin/stabled start --chain-id stable_988-1
Restart=always
RestartSec=3
LimitNOFILE=65535
StandardOutput=journal
StandardError=journal
SyslogIdentifier=stabled

[Install]
WantedBy=multi-user.target
EOF

sudo tee /etc/systemd/system/stabled.service > /dev/null <<EOF
[Unit]
Description=Stable Daemon Service
After=network-online.target

[Service]
User=$USER
ExecStart=/usr/bin/stabled start --chain-id stabletestnet_2201-1
Restart=always
RestartSec=3
LimitNOFILE=65535
StandardOutput=journal
StandardError=journal
SyslogIdentifier=stabled

[Install]
WantedBy=multi-user.target
EOF

Step 2: enable and start service

# Reload systemd configuration
sudo systemctl daemon-reload

# Enable service to start on boot
sudo systemctl enable stabled

# Start the service
sudo systemctl start stabled

# Check service status
sudo systemctl status stabled

# View logs
sudo journalctl -u stabled -f

Cosmovisor setup (recommended for automatic upgrades)

Cosmovisor is a process manager that automatically handles chain upgrades. This is the recommended setup for production nodes.

Step 1: install Cosmovisor

# Install Cosmovisor
go install cosmossdk.io/tools/cosmovisor/cmd/cosmovisor@latest

# Or download pre-built binary
wget https://github.com/cosmos/cosmos-sdk/releases/download/cosmovisor%2Fv1.7.0/cosmovisor-v1.7.0-linux-amd64.tar.gz
tar -xvzf cosmovisor-v1.7.0-linux-amd64.tar.gz
sudo mv cosmovisor /usr/bin/

# Verify installation
cosmovisor version

Step 2: set environment variables

# Add to ~/.bashrc or ~/.profile
echo "# Cosmovisor Configuration" >> ~/.bashrc
echo "export DAEMON_NAME=stabled" >> ~/.bashrc
echo "export DAEMON_HOME=$HOME/.stabled" >> ~/.bashrc
echo "export DAEMON_ALLOW_DOWNLOAD_BINARIES=true" >> ~/.bashrc
echo "export DAEMON_RESTART_AFTER_UPGRADE=true" >> ~/.bashrc
echo "export DAEMON_LOG_BUFFER_SIZE=512" >> ~/.bashrc
echo "export UNSAFE_SKIP_BACKUP=true" >> ~/.bashrc

# Load variables
source ~/.bashrc

Step 3: setup Cosmovisor directory structure

# Create cosmovisor directory structure
mkdir -p ~/.stabled/cosmovisor/genesis/bin
mkdir -p ~/.stabled/cosmovisor/upgrades

# Copy current binary to genesis
cp /usr/bin/stabled ~/.stabled/cosmovisor/genesis/bin/

# Create current symlink
ln -s ~/.stabled/cosmovisor/genesis ~/.stabled/cosmovisor/current

# Verify setup
ls -la ~/.stabled/cosmovisor/
cosmovisor run version

Step 4: set environment variable

# Set service name (default: stable)
export SERVICE_NAME=stable

Step 5: create service file

Mainnet
Testnet

sudo tee /etc/systemd/system/${SERVICE_NAME}.service > /dev/null <<EOF
[Unit]
Description=Cosmovisor daemon
After=network-online.target

[Service]
Environment="DAEMON_NAME=stabled"
Environment="DAEMON_HOME=$HOME/.stabled"
Environment="DAEMON_RESTART_AFTER_UPGRADE=true"
Environment="DAEMON_ALLOW_DOWNLOAD_BINARIES=true"
Environment="DAEMON_LOG_BUFFER_SIZE=512"
Environment="UNSAFE_SKIP_BACKUP=true"
User=$USER
ExecStart=$(which cosmovisor) run start --chain-id stable_988-1
Restart=always
RestartSec=3
LimitNOFILE=65535
StandardOutput=journal
StandardError=journal
SyslogIdentifier=${SERVICE_NAME}

[Install]
WantedBy=multi-user.target
EOF

sudo tee /etc/systemd/system/${SERVICE_NAME}.service > /dev/null <<EOF
[Unit]
Description=Cosmovisor daemon
After=network-online.target

[Service]
Environment="DAEMON_NAME=stabled"
Environment="DAEMON_HOME=$HOME/.stabled"
Environment="DAEMON_RESTART_AFTER_UPGRADE=true"
Environment="DAEMON_ALLOW_DOWNLOAD_BINARIES=true"
Environment="DAEMON_LOG_BUFFER_SIZE=512"
Environment="UNSAFE_SKIP_BACKUP=true"
User=$USER
ExecStart=$(which cosmovisor) run start --chain-id stabletestnet_2201-1
Restart=always
RestartSec=3
LimitNOFILE=65535
StandardOutput=journal
StandardError=journal
SyslogIdentifier=${SERVICE_NAME}

[Install]
WantedBy=multi-user.target
EOF

Step 6: enable and start service

# Reload systemd
sudo systemctl daemon-reload

# Enable service
sudo systemctl enable ${SERVICE_NAME}

# Start the service
sudo systemctl start ${SERVICE_NAME}

# Check status
sudo systemctl status ${SERVICE_NAME}

# View logs
sudo journalctl -u ${SERVICE_NAME} -f

Preparing for upgrades

When a chain upgrade is announced:

# Example: Preparing for v0.8.0 upgrade
UPGRADE_NAME="v0.8.0"
mkdir -p ~/.stabled/cosmovisor/upgrades/$UPGRADE_NAME/bin

# Download new binary
wget https://stable-data-dist.s3.us-east-1.amazonaws.com/testnet/binary/stabled-0.8.0-linux-amd64-testnet.tar.gz
tar -xvzf stabled-0.8.0-linux-amd64-testnet.tar.gz

# Place in upgrade directory
mv stabled ~/.stabled/cosmovisor/upgrades/$UPGRADE_NAME/bin/

# Verify the binary
~/.stabled/cosmovisor/upgrades/$UPGRADE_NAME/bin/stabled version

# Cosmovisor will automatically switch to this binary at the upgrade height

Monitoring Cosmovisor

# Check current binary version
cosmovisor run version

# View upgrade info
ls -la ~/.stabled/cosmovisor/upgrades/

# Check service logs for upgrade status
sudo journalctl -u ${SERVICE_NAME} | grep -i upgrade

# Monitor real-time logs during upgrade
sudo journalctl -u ${SERVICE_NAME} -f

Manual Systemd service setup (alternative)

If you prefer not to use Cosmovisor, you can create a standard systemd service:

Step 1: set environment variable

# Set service name (default: stable)
export SERVICE_NAME=stable

Step 2: create service file

Mainnet
Testnet

sudo tee /etc/systemd/system/${SERVICE_NAME}.service > /dev/null <<EOF
[Unit]
Description=Stable Daemon Service
After=network-online.target

[Service]
User=$USER
ExecStart=/usr/bin/stabled start --chain-id stable_988-1
Restart=always
RestartSec=3
LimitNOFILE=65535
StandardOutput=journal
StandardError=journal
SyslogIdentifier=${SERVICE_NAME}

[Install]
WantedBy=multi-user.target
EOF

sudo tee /etc/systemd/system/${SERVICE_NAME}.service > /dev/null <<EOF
[Unit]
Description=Stable Daemon Service
After=network-online.target

[Service]
User=$USER
ExecStart=/usr/bin/stabled start --chain-id stabletestnet_2201-1
Restart=always
RestartSec=3
LimitNOFILE=65535
StandardOutput=journal
StandardError=journal
SyslogIdentifier=${SERVICE_NAME}

[Install]
WantedBy=multi-user.target
EOF

Step 3: enable and start service

# Reload systemd configuration
sudo systemctl daemon-reload

# Enable service to start on boot
sudo systemctl enable ${SERVICE_NAME}

# Start the service
sudo systemctl start ${SERVICE_NAME}

# Check service status
sudo systemctl status ${SERVICE_NAME}

# View logs
sudo journalctl -u ${SERVICE_NAME} -f

Quick sync options

For faster synchronization, see the Snapshots & Sync Guide for:

Archive node snapshots
Pruned node snapshots

Post-installation verification

Check node status

# Check if node is running
sudo systemctl status stabled

# Check sync status
curl -s localhost:26657/status | jq '.result.sync_info'

# Check connected peers
curl -s localhost:26657/net_info | jq '.result.n_peers'

# Check latest block
curl -s localhost:26657/status | jq '.result.sync_info.latest_block_height'

Monitor logs

# Follow service logs
sudo journalctl -u stabled -f

# Check for errors
sudo journalctl -u stabled --since "1 hour ago" | grep -i error

# Check for peer connections
sudo journalctl -u stabled --since "10 minutes ago" | grep -i "peer"

Security hardening

After installation, secure your node:

Firewall configuration

# Configure UFW
sudo ufw allow 22/tcp  # SSH
sudo ufw allow 26656/tcp  # P2P
sudo ufw allow 26657/tcp  # RPC (only if needed externally)
sudo ufw enable
