Reach Distribution Contract

Reach Distribution is a smart contract developed on the Ethereum blockchain using Solidity programming language version 0.8.19 or later. This contract is intended to manage distributions and missions in a systematic and secure manner.

Features:

1. Ownership and Admin Control:

   • The contract utilizes OpenZeppelin's Ownable and ReentrancyGuard libraries to manage ownership and reentrancy attacks, respectively.
   • It also includes an admin system to allow for multiple administrators with different levels of control over the contract.

2. ERC-20 Token and Ether Distribution:

   • The contract supports distributions in both ERC-20 tokens and Ether.
   • It has a mechanism to toggle between token and Ether distributions.

3. Claiming System:

   • Users can claim rewards based on the amount allocated to them.
   • Each distribution can be uniquely identified using a version number.
   • The MerkleProof library is used to verify claims against a Merkle root, ensuring the authenticity of claims.

4. Missions:

   • The contract has a system to create missions, with each mission having a unique ID and a specified amount of funds allocated to it.

5. Events:

   • Events are emitted for significant actions within the contract, such as claims, creation of distributions, and missions, allowing for easier monitoring and auditing.

6. Fallback Function:

   • The contract includes a fallback function to receive Ether.

Getting Started

1. Prerequisites:

   • Ensure you have a development environment set up for Ethereum smart contracts (e.g., Truffle or Hardhat).
   • Install the necessary OpenZeppelin contracts and libraries as imported at the beginning of the contract.

2. Deployment:

   • Deploy the ReachDistribution contract to the Ethereum network using a migration script or through a development environment like Truffle.

3. Admin Management:

   • Use addAdmin and removeAdmin functions to manage admin addresses.
   • Toggle claiming functionality using the toggleClaiming function.

4. Creating Distributions:

   • Create a new distribution using the createDistribution function, specifying a new Merkle root and the total amount for the distribution.
   • Set the address of the ERC-20 token for distributions using setTokenAddress if necessary.

5. Claiming Rewards:

   • Users can claim their rewards using the claimRewards function by providing the amount and Merkle proof.

6. Creating Missions:

   • Create a new mission using the createMission function, specifying a mission ID and the amount allocated to the mission.

7. Withdrawal:

   • The owner can withdraw remaining funds from the contract using the withdraw function.

Security

• The contract uses ReentrancyGuard to prevent reentrancy attacks.
• Only the owner and admins have the authority to perform critical actions within the contract.
• The contract code should be audited by a professional smart contract auditor before mainnet deployment to ensure it's free from bugs and vulnerabilities.

Events

• Claimed: Emitted when a user claims rewards.
• DistributionCreated: Emitted when a new distribution is created.
• Received: Emitted when the contract receives Ether.
• MissionCreated: Emitted when a new mission is created.

Interfaces and Libraries

• The contract imports several libraries and contracts from OpenZeppelin for safe math operations, ownership management, reentrancy guard, and ERC-20 token standards.

Functions

The contract has various functions to manage distributions, claims, missions, admins, and the owner's control over the contract.

Future Improvements

• Any future improvements or updates to the contract can be managed by the owner or admins as necessary.
• Additional functionalities or optimizations may be added to enhance the contract's efficiency and usability.
