Create a collection of unique NFTs

What is an ERC721 smart contract and why are we using it?

The ERC721 token standard is widely known as the standard for non-fungible tokens (NFTs) on the Ethereum blockchain. ERC721 tokens represent unique and indivisible digital assets, each with its own distinct properties and value. Here are some key aspects of ERC721 utility:

  1. Ownership and Provenance: ERC721 tokens enable ownership and provenance tracking of unique assets. Each token within an ERC721 contract represents a specific item or piece of content, allowing for secure and transparent ownership records.

  2. Non-Fungibility: ERC721 tokens are non-fungible, meaning they are not interchangeable on a one-to-one basis. This characteristic makes ERC721 ideal for representing assets that are one-of-a-kind or have varying degrees of rarity.

  3. Limited Supply: Each ERC721 token has a limited supply, and each token ID is unique within the contract. This scarcity and uniqueness contribute to the value and desirability of the assets represented by ERC721 tokens.

Now, let's compare ERC721 to ERC1155:

The ERC1155 token standard is a flexible and efficient alternative to ERC721. It allows for the creation of both fungible and non-fungible tokens within a single smart contract. Here's an overview of ERC1155 utility:

  1. Efficiency and Scalability: ERC1155 tokens provide efficiency gains compared to individual ERC721 tokens. By managing multiple token types within a single contract, deployment costs are reduced, and scalability is improved. Additionally, batch transfers enable multiple token transfers in a single transaction, reducing gas costs and enhancing performance.

  2. Flexibility and Interoperability: ERC1155 tokens offer flexibility by allowing the creation of both fungible and non-fungible tokens within a single contract. This versatility makes ERC1155 suitable for applications requiring multiple asset types or token categories, such as gaming, where various in-game items with different attributes and rarity levels are necessary.

  3. Cost-Effectiveness: Using ERC1155, deploying a single contract for multiple token types is more cost-effective than deploying multiple ERC721 contracts for each unique token. This cost efficiency makes ERC1155 an attractive choice for projects that involve multiple assets or token categories.

In summary, ERC721 tokens are well-suited for representing unique and indivisible assets, focusing on ownership and provenance tracking. On the other hand, ERC1155 tokens provide flexibility and efficiency by supporting both fungible and non-fungible tokens within a single contract, making them more suitable for projects requiring multiple token types or applications that benefit from cost-effectiveness and interoperability.

How can I create one? how to use it?

Here's the step-by-step guide for creating an ERC721 smart contract using Zero-Code Smart Contract Factory, incorporating the additional details you provided:

Step 1: Select Blockchain and Smart Contract Standard In Zero-Code Smart Contract Factory, choose the blockchain on which you want to deploy your smart contract. Select from Ethereum, Polygon, or Binance Smart Chain. Then, specify the smart contract standard you will be working with: ERC721 or ERC1155.

Step 2: Enter Project Details Enter the project details, including the project name, description, owner's wallet address, treasury wallet address, and royalty wallet address. These details are important for setting up ownership and revenue distribution for your NFTs.

Step 3: Define Token Details Specify the token details, such as the token symbol, maximum supply, royalty shares rate, maximum number of NFTs per transaction, team-reserved NFTs, and the maximum number of NFTs an individual can own. These parameters allow you to customize the behavior and restrictions of your NFTs.

Step 4: Add NFT Creatives and Metadata Drag and drop the NFT creatives and metadata files or use pre-reveal versions if available. This step involves uploading the visual assets and associated metadata that will be attached to each NFT, providing additional information and context.

Deploying pre-revealed Non-Fungible Tokens (NFTs) is a method used by creators to build suspense and fair opportunity within their communities. In this process, NFTs are minted and listed on the marketplace without revealing their unique attributes or traits. Instead, they are typically represented by a generic placeholder image. The actual metadata – which describes the unique characteristics of each NFT, such as appearance, rarity, or traits – is kept hidden until a pre-determined reveal time. At the reveal time, the metadata on the smart contract is updated, and the unique properties of each NFT become viewable on the marketplace. This revealing is typically done by the creator calling a function in the smart contract, although the specific process may vary based on the marketplace and the contract itself. Refreshing the metadata on the marketplace then displays the true attributes of the NFTs, turning the previously identical NFTs into unique assets.

Step 5: Set Sales and Minting Parameters Set the sales date and minting price for your NFTs. You can also choose to add a whitelist for exclusive access and set a separate presale mint date and price if desired. These parameters allow you to control the availability and pricing of your NFTs during different stages.

Step 6: Verify and Deploy Verify the contract details, ensuring that all the entered information is correct and aligns with your intended deployment. Once verified, initiate the deployment process, and Zero-Code Smart Contract Factory will deploy your ERC721 smart contract to the chosen blockchain.

Step 7: Generate Designed Mint Experience After deploying the smart contract, generate a designed mint experience using an iframe. Implement this mint experience in your application to provide a user-friendly interface for minting NFTs.

Step 7a: Update Whitelist Update the whitelist as needed, adding or removing addresses that have exclusive access to purchase or mint NFTs.

Step 7b: Airdrop NFTs Utilize the airdrop functionality to distribute NFTs to a specific list of individuals. Upload their wallet addresses and initiate the airdrop process to reward them with NFTs.

By following these steps, you can create an ERC721 smart contract using Zero-Code Smart Contract Factory, customizing various parameters and details to match your project requirements.
