SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill enables secure, trustless atomic swaps between the Ark blockchain and the Lightning Network by implementing Virtual Hash Time-Locked Contracts (VHTLCs).

Core Features & Use Cases

  • Atomic Swaps: Facilitates trustless exchange of assets between Ark and Lightning.
  • VHTLC Implementation: Defines the on-chain and off-chain spending paths for VHTLCs.
  • Use Case: Use this skill to initiate or claim funds in a swap where you are sending Ark to the Lightning Network, or vice-versa, ensuring that either both parties receive their intended assets or neither does.

Quick Start

Use the fulmine-vhtlc skill to create a VHTLC from the provided options.

Frequently Asked Questions about Fulmine VHTLC (Virtual Hash Time-Locked Contract)

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I execute trustless atomic swaps between Ark and the Lightning Network?▼

Atomic swaps between Ark and the Lightning Network use Virtual Hash Time-Locked Contracts to enable trustless exchange. This implementation defines specific on-chain and off-chain spending paths to ensure either both parties receive their assets or neither does.

What spending paths are defined in a VHTLC for cryptocurrency swaps?▼

A Virtual Hash Time-Locked Contract defines six spending paths for cryptocurrency swaps, including collaborative and unilateral claim or refund options. These paths operate under specific timelock constraints to secure the trustless exchange.

How do I create a VHTLC from existing tapscripts?▼

You can create a Virtual Hash Time-Locked Contract from existing tapscripts or from predefined options. This allows for flexible VHTLC creation tailored to specific atomic swap requirements between Ark and the Lightning Network.

When do I need a Virtual Hash Time-Locked Contract for Lightning Network transactions?▼

You need a Virtual Hash Time-Locked Contract when sending Ark to the Lightning Network or vice-versa. It provides the trustless infrastructure to ensure funds are only claimed when both sides of the atomic swap are completed.

Can I manage repository domain models when implementing VHTLCs?▼

Yes, the VHTLC implementation provides domain models for repository management. This supports the structured creation and lifecycle tracking of Virtual Hash Time-Locked Contracts during Ark and Lightning atomic swaps.
