What is the ERC-721 standard?​

The Standard. ERC-721 defines a minimum interface a smart contract must implement to allow unique tokens to be managed, owned, and traded. It does not mandate a standard for token metadata or restrict adding supplemental functions. pragma solidity ^ 0.4.20 ; /// @title ERC-721 Non-Fungible Token Standard /// @dev See https://github.

What is _setbaseuri in erc721?​

This is an internal detail of the ERC721 contract and its use is deprecated. Gets the token name. Gets the token symbol. Returns the URI for a given token ID. May return an empty string. If the token’s URI is non-empty and a base URI was set (via _setBaseURI ), it will be added to the token ID’s URI as a prefix.

What is the erc721full token?​

What is the erc721full token?
The fully featured token implementing all three interfaces is prepackaged as ERC721Full. Additionally, IERC721Receiver can be used to prevent tokens from becoming forever locked in contracts.

What is the erc721 preset contract?​

Preset ERC721 contract A preset ERC721 is available, ERC721PresetMinterPauserAutoId. It is preset to allow for token minting (create) with token ID and URI auto generation, stop all token transfers (pause) and allow holders to burn (destroy) their tokens. The contract uses Access Control to control access to the minting and pausing functionality.
The ERC-721 (Ethereum Request for Comments 721), proposed by William Entriken, Dieter Shirley, Jacob Evans, Nastassia Sachs in January 2018, is a Non-Fungible Token Standard that implements an API for tokens within Smart Contracts.

What is the difference between erc721 and erc1155 tokens?​

Enjin has created a new and approved Ethereum token standard, ERC1155 and we are extremely delighted to have Witek Radomski, Co-founder and CTO of Enjin to share with us the difference between ERC721 and ERC1155 tokens. ERC-1155: Allows new concepts like semi-fungible tokens.

What is an ERC-721 Non-Fungible Token Contract?​

What is an ERC-721 Non-Fungible Token Contract?
If a Smart Contract implements the following methods and events it can be called an ERC-721 Non-Fungible Token Contract and, once deployed, it will be responsible to keep track of the created tokens on Ethereum. Let’s see how a Standard is so important to make things simple for us to inspect any ERC-721 Token Contract on Ethereum.

What is ERC-1155 and why does it matter?​

ERC-1155: Includes standardized events for mints, burns, transfers, approvals, and metadata changes. This permits cool ecosystem benefits like deep data analytics on tokens and rich token explorers. There you have it! The insights of the man who made ERC1155 possible.

ERC-721 (Ethereum Request for Comments 721) standard, proposed in January 2018 by William Entriken, Dieter Shirley, Jacob Evans, and Nastassia Sachs, defines a minimum interface that a smart contract must implement to manage, own, and trade unique tokens. It provides the infrastructure for creating non-fungible tokens (NFTs) on the Ethereum blockchain.

The `_setBaseURI` function in the ERC-721 contract is an internal function that was used to set the base URI for token metadata. However, its usage is now deprecated. It allows getting the token's name, symbol, and URI for a given token ID. If a base URI was set, it will be added as a prefix to the token ID's URI.

ERC721Full is a prepackaged token that implements all three interfaces defined in the ERC-721 standard. It offers a fully featured NFT implementation. Additionally, the `IERC721Receiver` interface can be utilized to prevent tokens from being permanently locked in contracts during transfers.

The Preset ERC721 contract, specifically ERC721PresetMinterPauserAutoId, is a ready-to-use ERC721 implementation. It allows for token minting with auto-generated token IDs and URIs, pause functionality to stop token transfers, and token burning capability for token holders. Access Control is utilized to manage access to minting and pausing operations.

On the other hand, ERC-1155 is a newer Ethereum token standard created by Enjin, which introduces unique features like semi-fungible tokens. It includes standardized events for mints, burns, transfers, approvals, and metadata changes, enabling advanced functionalities such as deep data analytics on tokens and enhanced token explorers.

In summary, ERC-721 focuses on non-fungible tokens while ERC-1155 introduces semi-fungible tokens and additional functionalities, catering to different use cases within the blockchain ecosystem.
