MPC based TSS Wallets Service

This is a Go application implementing a MPC based Threshold Signature Scheme (TSS) wallet service using a TSS library. The service allows clients to create wallets and sign data (e.g. transactions) in a distributed manner without revealing the private key to any single party.

It was built using the tss-lib, which simplifies the process of distributed key generation and signing. Gin Gonic was used for handling API endpoints due to its ease of use and performance. While the tss-lib requires the use of channels for concurrency, additional channels were introduced to improve performance and scalability, especially as the number of parties per wallet increases.
