Runes <-> Spark bridge

This repository contains the implementation of a bridge that allows users to transfer Runes tokens between the Bitcoin and Spark L2. The bridge utilizes a multi-signature vault mechanism to ensure secure and trustless transfers.

Through this service, users can:

• Safely deposit BTC Runes to receive wrapped Runes (wRunes) on the Spark side;
• Deposit Spark wRunes to redeem BTC Runes back.
