Lightning Nodes
Common questions and answers about Comet Platform
Account and Billing
Can I switch from monthly to annual billing?
Yes. You can switch between monthly and annual billing at any time through the dashboard or by updating your subscription via the API. The billing service automatically handles proration and updates your subscription frequency accordingly.
What happens if I run out of credits?
Existing nodes continue running. You cannot deploy new nodes until you free up credits by deleting unused nodes or upgrading your subscription plan.
Can I get a refund?
Contact billing@cometcash.com for refund requests. Refund policies may vary based on your subscription plan and billing cycle.
How do I cancel my subscription?
You can cancel your subscription through the dashboard (Dashboard → Billing → Subscription → Cancel) or via the API. Nodes remain active until the current billing period ends. You can also reactivate your subscription if needed.
Can I pay with Bitcoin or Lightning?
Yes! Comet supports both traditional payment methods (credit/debit cards via Stripe) and Bitcoin/Lightning payments via BTCPay integration. You can choose your preferred payment method when creating or updating your subscription.
Do credits roll over?
No. Credits represent capacity, not consumable units. Deployed resources continuously occupy credits across billing cycles. If you downgrade your plan and are using more credits than the new plan allows, you'll need to free up resources before the downgrade can be completed.
Technical
Can I SSH into my nodes?
No. All node operations are performed via the API, SDK, or dashboard. This ensures security and consistent management of your nodes.
Can I run custom software on nodes?
No. Nodes run standard, unmodified implementations of Tapd, LND, or Bitcoin Core to ensure compatibility and security.
How do I migrate from self-hosted?
Migration from self-hosted nodes is supported. For LND nodes, you can use Static Channel Backups (SCB). For Tapd nodes, you can export/import asset state. Contact support for detailed migration assistance.
Can I run multiple nodes?
Yes! You can run as many nodes as your credit capacity allows. Each node type (LND, Tapd, Bitcoin Core) consumes credits based on its tier.
What happens to my data if Comet shuts down?
You maintain full control of your data. You can download encrypted backups at any time through the dashboard or API. All backups are encrypted with your password, which means you can decrypt them locally and restore your nodes elsewhere if needed.
Security
Does Comet have access to my private keys?
No. All sensitive data (seed phrases, macaroons, private keys) is encrypted client-side using your password. Comet servers only store encrypted data and cannot decrypt it without your password. Your password is never transmitted to or stored on Comet servers.
What if I forget my password?
Your password cannot be recovered. This is a security feature to ensure that even Comet cannot access your encrypted data. Always backup your password securely and store it in a safe location. If you lose your password, you will not be able to decrypt your backups.
Is Comet audited?
Comet conducts regular security audits and is working toward industry-standard certifications. Contact support@cometcash.com for specific audit information.
How is data encrypted?
Client-side encryption uses AES-256-CBC with an encryption key derived from your password. All data in transit is protected with TLS 1.3. Your password is used to encrypt sensitive node data (macaroons, seed phrases) before it’s sent to Comet servers.
Can Comet employees access my funds?
No. The non-custodial architecture ensures that Comet employees cannot access your funds. Private keys are encrypted with your password, which only you know, making it technically impossible for anyone else to decrypt your node credentials or access your funds.
Integration
Which programming languages are supported?
Comet provides official SDKs for Python and JavaScript/TypeScript. For other languages, you can use the standard REST or gRPC APIs provided by the underlying node software (LND, Tapd, Bitcoin Core).
Can I use Comet with existing Lightning apps?
Yes! Comet nodes expose standard LND REST APIs, so any LND-compatible application can connect to your Comet nodes. Your nodes work with standard Lightning Network tools and applications.
Can I run a Taproot Assets Universe server?
Currently, Comet nodes can connect to external Universe servers. Running your own Universe server on Comet infrastructure may be available in future updates. Contact support for the latest information.
Does Comet support other Lightning implementations (CLN, Eclair)?
Currently, Comet supports LND for Lightning Network nodes. Support for other Lightning implementations may be added based on user demand. Contact support to express interest in additional node types.
