# SC TECH Santa

Santa currently uses solidity version 0.7.6

## Overview

Santa is a way where the user can gift cryptocurrencies to users that do not even have an existing wallet, new to crypto along with the users with an existing Jigstack wallet. 

Smart contracts deployed using OpenZeppelin Upgrades Plugins can be upgraded to modify their code, while preserving their address, state, and balance. 

This allows you to iteratively add new features to your project, or fix any bugs you may find in production. Wallet & Sanya has the Proxy partner to deploy and update contracts on the blockchain and uses the OpenZeppelin upgrades library.
