TokenERC1155 Contract
This contract implements the ERC-1155 standard for managing non-fungible tokens. It allows users to mint, transfer, and manage unique digital assets.
Features
- Minting of new ERC-1155 tokens
- Transferring tokens between accounts
- Setting base URI for token metadata
- Checking token balance for individual accounts
- Batch minting and batch transferring
Usage
To use the TokenERC1155 contract, you need to first deploy it to a blockchain. Once deployed, you can interact with the contract through its functions.
Functions
Write Functions
- mint(address to, uint256 id, uint256 amount, bytes memory data): Mints new tokens of a specific ID to a designated recipient.
- mintBatch(address to, uint256[] memory ids, uint256[] memory amounts, bytes memory data): Mints a batch of new tokens with different IDs to a recipient.
- setURI(string memory newuri): Sets the base URI for fetching token metadata.
Read Functions
- balanceOf(address owner, uint256 id): Retrieves the balance of a specific token ID for a given account.
- balanceOfBatch(address[] memory owners, uint256[] memory ids): Retrieves the balance of multiple token IDs for multiple accounts.
- uri(uint256 id): Returns the URI for a specific token ID.
Events
- TransferSingle(address operator, address from, address to, uint256 id, uint256 value): Emitted when a single token is transferred.
- TransferBatch(address operator, address from, address to, uint256[] memory ids, uint256[] memory values): Emitted when a batch of tokens are transferred.
- ApprovalForAll(address owner, address operator, bool approved): Emitted when an operator is approved or revoked for an owner.
Implementation Details
The contract utilizes the OpenZeppelin ERC1155 implementation as a foundation, ensuring compatibility with the established standard.
Best Practices
- Use a secure random number generator for minting unique token IDs.
- Consider implementing access control mechanisms to limit minting and other actions.
- Store token metadata off-chain for better scalability and cost efficiency.
