🆕 New Features

Network Selection

Supports both Mainnet and Testnet:

export NETWORK_TYPE=testnet  # or mainnet (default)
./celestia-manager.sh

Custom Installation Directory

Install to custom location (e.g., separate disk):

export CELESTIA_HOME=/mnt/data/.celestia-app
./celestia-manager.sh

Script now checks disk space of selected directory, not just root filesystem.

DA Nodes Management

Complete suite for Data Availability nodes:

• Main Menu → Option 5 (Data Availability Nodes)
• Option 1 → Install DA Node (submenu for all DA types)
• Support for Bridge, Full Storage, and Light nodes
• Unified management interface

---

🔄 Quick Update

./celestia-manager.sh
# Select: 2 (Update Node) → Press Enter for latest version

---

🛡️ Security Best Practices

• 🔐 Backup ~/.celestia-app/config/priv_validator_key.json
• 🔥 Use script's firewall configuration (Option 3 → 5)
• 🔑 Enable SSH key-based authentication
• 👁️ Setup monitoring and alerts
• 💰 Never share private keys or seed phrases

🐛 Troubleshooting

Node not syncing?

sudo journalctl -u celestia-appd -f -n 100
celestia-appd status 2>&1 | jq .SyncInfo

Service won't start?

sudo systemctl status celestia-appd
sudo journalctl -u celestia-appd -n 50 --no-pager

Check sync status:

./celestia-manager.sh
# Select: 7 (Status & Logs) → 2 (Check Sync Status)
