## Overview

The T-REX (Token for Regulated EXchanges) protocol is a comprehensive suite of Solidity smart contracts, 

implementing the [ERC-3643 standard](https://eips.ethereum.org/EIPS/eip-3643) and designed to enable the issuance, management, and transfer of security 

tokens in 

compliance with regulations. It ensures secure and compliant transactions for all parties involved in the token exchange.

## Key Components

The T-REX protocol consists of several key components:

- **[ONCHAINID](https://github.com/onchain-id/solidity)**: A smart contract deployed by a user to interact with the security token or any other application 

  where an on-chain identity may be relevant. It stores keys and claims related to a specific identity.

- **Trusted Issuers Registry**: This contract houses the addresses of all trusted claim issuers associated with a specific token.

- **Claim Topics Registry**: This contract maintains a list of all trusted claim topics related to the security token.

- **Identity Registry**: This contract holds the identity contract addresses of all eligible users authorized to hold the token. It is responsible for claim verification.

- **Compliance Smart Contract**: This contract independently operates to check whether a transfer is in compliance with the established rules for the token.

- **Security Token Contract**: This contract interacts with the Identity Registry to check the eligibility status of investors, enabling token holding and transactions.

## Getting Started

1. Clone the repository: `git clone https://github.com/TokenySolutions/T-REX.git`

2. Install dependencies: `npm ci`

3. Compile the contracts: `hardhat compile`

4. Run tests: `hardhat test`

## Documentation

For a detailed understanding of the T-REX protocol, please refer to the [whitepaper](./docs/TREX-WhitePaper.pdf).

All functions of T-REX smart contracts are described in the [T-REX documentation](https://docs.tokeny.com/docs/smart-contracts)
