EXPLAIN ABOUT THE ERC-1155 TOKEN IN DETAIL

The ERC-1155 token is a standard token, which allows us to be able to create any type of asset, such as digital art, game items, real estate and currency, and so on.

Within one year after being launched, the ERC-1155 token has become an official Ethereum standard token and can be used for the entire Ethereum development community.

ERC1155 standard token is also a smart contract which regulates all token amounts, Each token is semi-fungible, unlike ERC-721 non-fungible token which can only be owned by one address. This feature has several implications for Mocktail tokens; multiple addresses can have each token, and one address can have multiple copies of each token.

The ERC1155 token has the aim of having a better reputation in the future, this ERC1155 token also has its own characteristics where the ERC1155 token only uses one smart contract to represent all tokens at once. This is the reason why balanceOffs are different from ERC20 and ERC777, it has additional arguments to recognize the token that we want to ask about the balance,

HOW DO YOU VERIFY THE NUMBER OF TOKEN ERC-721 WHEN YOU DO YOUR HOME JOB DUTIES

ERC-721 is an open and free standard that describes how to create a non-exchangeable token that is distinctive or unique on the Ethereum blockchain. Even though most of our tokens can be exchanged (each token is the same as every other token), ERC-721 tokens are all unique and have their own characteristics. ***

DESCRIBE ABOUT THE TRC-20 TOKEN AND HOW YOU VERIFY THE NUMBER OF TOKEN AVAILABLE WHEN YOU DO YOUR HOME JOB DUTIES

The TRC‌-20 token is a technical standard token designed to create smart contracts on the TRON blockchain network. TRC-20 is designed by vuna to implement tokens with the TRON Virtual Machine (TVM) which are all compatible with Ethereum's ERC‌-20 token, not only that The strength of the TRC-20 token can be said to be equivalent to the strength of the ERC-20 token on the Ethereum blockchain. Not only that, the TRC-20 token is also able to operate on ERC-20 tokens, because the script from the TRC-20 tokens can be used in ERC-20 tokens, so this makes it easier for any developer who used to use an ERC-20 smart contract, can directly moved on to the TRC-20 without bothering to organize the scripts they generated.

--- ***TOKEN NAME:*** the name of the token used. ***TOKEN ABBREVIATION:*** token symbol. ***TOKEN PRECISION:*** shows several token units to be divided. ***TOTAL SUPPLY*** This total supply serves to return the total supply of tokens stored by the contract. ***BALANCEOF*** Its function is to return the balance and ask for another address balance. ***TRANSFER*** has a function to send tokens from one user to another. ***APPROVE*** 's function is to limit the number of tokens that can be taken by the smart contract. If this approve doesn't exist, we could lose the balance. ***ALLOWANCE*** can be used simultaneously with approve. as long as the contract permission is given to us to manage the tokens besides that we can also check how many tokens were withdrawn. ###
