Insomnia NFT

Description

This repository demonstrates a Multi-Utility NFT contract with:

1. Phased Minting (using Merkle Proofs).
2. Discount Verification with Signatures.
3. Vesting Integration (Sablier).
4. Security Best Practices.
5. A Foundry Test Suite (target: 80%+ Coverage).

File Overview

• src/InsomniaNFT.sol
  Main NFT contract implementing:

  • Phased minting (phase 1: free for whitelisted users, phase 2: discounted, phase 3: open to all).
  • Merkle proof verification.
  • Signature checking for discount eligibility.
  • Sablier vesting integration for mint fees.

• src/InsomniaToken.sol
  ERC20 token used for mint payments.

• test/
  Foundry test contracts covering:

  • Minting phases.
  • Merkle proof correctness.
  • Signature validation.
  • Vesting logic (Sablier).
  • Additional edge cases.

• script/Deploy.s.sol
  A sample Foundry script to deploy both the ERC20 token and NFT contract on a chain.

Getting Started

1. Install Foundry (if not already installed):

   curl -L https://foundry.paradigm.xyz | bash
   foundryup

2. Clone the repository:

   git clone <REPO_LINK>
   cd insomnia-nft

3. Install Dependencies:

   forge install
   • This will download the required packages, including OpenZeppelin and Sablier (if configured).

4. Build & Test:

   forge build
   forge test

Coverage

To generate the coverage report, make sure you have llvm-cov or related requirements installed, then run:

forge coverage

Your goal is to achieve 80% or higher overall coverage.

Security

The contract is designed with security in mind, addressing:

• Reentrancy protection (e.g., checks-effects-interactions, or modifiers like nonReentrant if needed).
• Signature validation (to ensure discounted minting can’t be exploited).
• Merkle proof checks (preventing unauthorized mints).
• Access control using Ownable (limit certain functions to the contract owner).
• Input validation and revert conditions.
