Sample Hardhat Project

This project demonstrates a basic Hardhat use case. It comes with a sample contract, a test for that contract, and a script that deploys that contract.

Try running some of the following tasks:

npx hardhat help
npx hardhat test
REPORT_GAS=true npx hardhat test
npx hardhat node
npx hardhat run scripts/deploy.ts

Airdrop and GauntletNFT Contracts

This project includes three Solidity smart contracts that implement an Airdrop system and an ERC-721 token named GauntletNFT on the Ethereum blockchain.

1. Airdrop Contract

Smart Contract Details

  • Name: Airdrop
  • SPDX-License-Identifier: MIT
  • Dependencies: OpenZeppelin's MerkleProof, IERC721

Functions

  • constructor(address _token, bytes32 _merkleRoot)
  • claim(bytes32[] calldata merkleProof) external
  • canClaim(address claimer, bytes32[] calldata merkleProof) public view returns (bool)

Usage

  • Deploy the Airdrop contract, providing the address of the airdrop NFT token and the merkle root.
  • Candidates can claim their airdrop by calling the claim function with a valid merkle proof.

2. GauntletNFT Contract

Smart Contract Details

  • Name: GauntletNFT
  • SPDX-License-Identifier: MIT
  • Dependencies: OpenZeppelin's ERC721, ERC721URIStorage, AccessControl, Counters

Functions

  • constructor()
  • safeMint(address to, string memory uri) public onlyRole(MINTER_ROLE)

Usage

  • Deploy the GauntletNFT contract.
  • Mint new NFTs by calling the safeMint function, which can only be called by addresses with the MINTER_ROLE.

##3. IERC721 Interface

###Smart Contract Details Name: IERC721 SPDX-License-Identifier: MIT

Functions

  • safeMint(addres to) external;

Usage

  • Implement this interface in contracts that should be able to mint NFTs.
