NFTs

NFTs are non-fungible tokens that represent unique digital assets on the blockchain. They can be used to create, buy, sell, and collect digital art, music, games, and more.

Features

Uses Solidity to write smart contracts for creating and managing NFTs
Uses Hardhat to compile, test, and deploy smart contracts
Uses OpenZeppelin to implement ERC-721 and ERC-1155 standards for NFTs
Uses IPFS to store and access the metadata and content of NFTs
Uses Ethers3.js to connect the web interface with the blockchain

ERC721

Sepolia is a smart contract that implements the ERC-721 standard for non-fungible tokens (NFTs).
Sepolia allows the owner to pause and unpause the contract, and to edit the minting options.
Sepolia has two minting options: public mint and allow mint. Public mint is open to anyone who pays 0.001 ether, while allow mint is restricted to a list of addresses that pay 0.0001 ether.
Sepolia has a maximum supply of 10 NFTs, and each NFT has a unique token ID and a base URI that points to the IPFS metadata and content.
Sepolia uses OpenZeppelin contracts for security, access control, and enumeration features.
Sepolia also has a withdraw function that allows the owner to transfer the balance of the contract to a specified address.

ERC1155

DappUni is a smart contract that implements the ERC-1155 standard for multi-token NFTs.
DappUni allows the owner to pause and unpause the contract, and to set the base URI for the NFT metadata and content.
DappUni has two types of NFTs, with IDs 0 and 1, and each type has a maximum supply of 10 NFTs.
DappUni has two minting options: allow list mint and public mint. Allow list mint is restricted to a list of addresses that pay 0.0001 ether per NFT, while public mint is open to anyone who pays 0.001 ether per NFT.
DappUni also has a purchase limit of 5 NFTs per address, and a purchase count mapping to keep track of the number of NFTs purchased by each address.
DappUni uses OpenZeppelin contracts for security, access control, enumeration, and payment splitting features.
DappUni splits the payments among a list of payees with specified shares, using the PaymentSplitter contract.
