Overview

This is a Security Token smart contract implementation from Upside.
The core purpose of the token is to enforce transfer restrictions for certain groups.

This implementation attempts to balance simplicity and sufficiency for smart contract security tokens that need to comply with regulatory authorities - without adding unnecessary complexity for simple use cases.

Solana Security Token consists of several modules:

• Access Management
• Transfer Groups and Rules Management
• Token2022 Security Token Tansfer
• Token Lockup Vestings
• Dividends Distribution
