ERC721F

The goal of ERC721F is to provide a simple extension of IERC721 with significant gas savings for minting multiple and single NFTs in a single transaction. This project and implementation will be updated regularly and will continue to stay up to date with best practices. Another key goal of ERC721F is to facilitate educational opportunities for new web3 developers, fostering a supportive learning environment and driving innovation within the community.

ERC721F Extends ERC721 Non-Fungible Token Standard basic implementation. ERC721F eliminates the need for ERC721Enumerable, yet retains the functionality of totalSupply() and walletOfOwner(address _owner).

The Author is not liable for any outcomes as a result of using ERC721F. DYOR!

Roadmap

  • [] Add more documentation on benefits of using ERC721F
  • [] Continue to try to reduce gas costs
  • [] Start automated testing

See the open issues for a full list of proposed features (and known issues).

Usage

Installation

npm install '@franknft.eth/erc721-f'

Just import the file from the package like this:

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.20 <0.9.0;

import "@franknft.eth/erc721-f/contracts/token/ERC721/ERC721FCOMMON.sol";

contract Example is ERC721F {
    constructor() ERC721F("Example", "Example", msg.sender) {
        setBaseTokenURI("ipfs://QmVy7VQUFtTQawBsp4tbJPp9MgbTKS4L7WSDpZEdZUzsiD/");
    }

    /**
     * Mint your tokens here.
     */
    function mint(uint256 numberOfTokens) external {
        require(msg.sender==tx.origin,"No Contracts allowed.");
        uint256 supply = totalSupply();
        for(uint256 i; i < numberOfTokens;){
            _mint( msg.sender, supply + i ); // no need to use safeMint as we don't allow contracts.
            unchecked{ i++;}
        }
    }
}

Running tests locally

Hardhat

  1. Copy .env.example and rename to .env
  2. nvm use
  3. npm install
  4. npx hardhat compile
  5. npx hardhat test

Warning When running any test of a contract located in /examples, you'll receive a compilation error due to the @franknft.eth/erc721-f library not being installed. To prevent this error you must change all imports where @franknft.eth/erc721-f to the location of the local file. For example "../contracts/utils/AllowList.sol" in the AllowList example.

Warning Since hardhat only compiles a single path at once, you'll probably fail every single test that's executed on solutions located in /examples. This is because those artifacts haven't been created yet. These can be created by changing the the sources path in hardhat.config.js to "./examples" and executing step 3 again.

Note: npx hardhat clean removes the created artifacts

Running a single test

npx hardhat test ./test/token/ERC721/GasUsage.test.js

Testing gas consumption
  • Enable the creation of a gas report by setting REPORT_GAS to true in .env
  • Toggle the creation of a gas report file by (un)commenting outputFile in hardhat.config.js
  • Change the total runs and toggle the optimizer by changing the solidity optimizer values in hardhat.config.js

Foundry

  1. Install Rust
  2. Install Foundry
  3. forge build
  4. forge test

Running a single test

forge test --match-path test\foundry\token\ERC721\ERC721FGasReporterMock.t.sol

Testing gas consumption

forge test --gas-report
