Quick Wins (5-30 minutes each)

Completed ✅

• Secure .env file (5 minutes)

  • Run: chmod 600 ~/.env

• Add backup script (30 minutes)

  • Create simple backup script
  • Schedule with cron

• Enable metrics (verify)

  • Verify metrics port 9545 is accessible
  • Configure Prometheus scraping

• Create snapshots before changes (manual)

  • Document snapshot procedure
  • Add to deployment checklist

• Add health check monitoring (1 hour)

  • Schedule health checks
  • Alert on failures

Pending

• Add progress indicators (1 hour)

  • Add progress bars to scripts
  • Show current step in multi-step processes

• Add --dry-run flag (2 hours) — Script added

  • Example pattern in scripts/utils/dry-run-example.sh (use DRY_RUN=1 or --dry-run)
  • Integrated: scripts/validation/validate-config-files.sh [--dry-run], scripts/deployment/deploy-transaction-mirror-chain138.sh [--dry-run]; others in scripts/ already support --dry-run (see scripts/README.md).
