Lightning Swaps

This Clarity smart contract facilitates delegated stacking by enabling secure swaps of Lightning Bitcoin (BTC) for STX tokens. It uses the Lightning Service Authentication Tokens (LSAT/402) protocol to authenticate users and register their Bitcoin reward addresses transparently linked to their STX holder address. The contract is part of a broader decentralized application (rStack) that leverages Gaia for data storage, aiming to help small STX token holders participate in proof-of-transfer.

Key Features

• Fraud-Proof Swaps — Securely exchanges Lightning BTC for STX tokens using LSAT protocol, with macaroon-based proof of payment and metadata locking.
• Delegated Stacking — Allows small STX holders to participate in proof-of-transfer by registering Bitcoin reward addresses linked to their STX address.
• Transparent Registration — Registers stackers' reward addresses in conjunction with STX token purchases via LSAT, ensuring service-level agreement compliance.
• Decentralized Infrastructure — Part of a fully decentralized application (rStack) that uses Gaia for data storage, promoting user sovereignty.

Philosophy

The project emphasizes decentralized infrastructure and multiple service providers, recognizing that not all users will run the blockchain locally, while focusing on secure, transparent token swaps for broader participation in proof-of-transfer.
