DiamondSwap ERC20 Minimal Interface (IERC20Minimal)

The DiamondSwap ERC20 Minimal Interface (IERC20Minimal) is a streamlined version of the standard ERC20 interface, designed for simplicity and efficiency within the DiamondSwap protocol. It provides essential ERC20 functionality while minimizing complexity, making it ideal for use in contracts where only basic token operations are required. Below is a detailed breakdown of the functions and events in the DiamondSwap ERC20 Minimal Interface.

Functions

name() → string

This function returns the name of the ERC20 token. The token's name is typically a descriptive identifier that represents the asset, such as "DiamondSwap Token."

• Returns: A string representing the token's name.

symbol() → string

This function returns the symbol of the ERC20 token. The symbol is a shorter identifier, often used in trading interfaces. For example, "DIA" might be the symbol for the DiamondSwap Token.

• Returns: A string representing the token's symbol.

decimals() → uint8

This function returns the number of decimal places the token uses. Decimals indicate the divisibility of the token, where a value of 18 means that the token can be divided down to 10^(-18) of its base unit, similar to how Ethereum's smallest unit is called "wei."

• Returns: An unsigned 8-bit integer (uint8) representing the number of decimals.

totalSupply() → uint256

This function returns the total supply of the ERC20 token. Total supply refers to the total amount of the token that currently exists in circulation.

• Returns: An unsigned 256-bit integer (uint256) representing the total supply of the token.

balanceOf(address owner) → uint256

This function returns the balance of a specific address. The balance represents the amount of the ERC20 token owned by the address.

• owner: The address whose balance is being queried.
• Returns: An unsigned 256-bit integer (uint256) representing the balance of the specified address.

transfer(address recipient, uint256 amount) → bool

This function allows the transfer of tokens from the caller's address to another address. It moves the specified amount of tokens to the recipient's address.

• recipient: The address receiving the tokens.
• amount: The number of tokens to transfer.
• Returns: A boolean value indicating whether the transfer was successful.

allowance(address owner, address spender) → uint256

This function returns the remaining number of tokens that a spender is allowed to spend on behalf of the owner. This allowance is initially set by the approve function and is typically used for automated or contract-based token transfers.

• owner: The address that owns the tokens.
• spender: The address allowed to spend the tokens.
• Returns: An unsigned 256-bit integer (uint256) representing the remaining allowance for the spender.

approve(address spender, uint256 amount) → bool

This function sets the allowance for a spender to transfer up to a specified number of tokens on behalf of the caller (the token owner). This is often used to authorize a contract or another user to handle your tokens.

• spender: The address authorized to spend the tokens.
• amount: The maximum number of tokens that can be spent.
• Returns: A boolean value indicating whether the approval was successful.

transferFrom(address sender, address recipient, uint256 amount) → bool

This function allows a spender to transfer tokens on behalf of another address (sender). The amount transferred must not exceed the allowance set by the approve function.

• sender: The address from which the tokens are being transferred.
• recipient: The address receiving the tokens.
• amount: The number of tokens to transfer.
• Returns: A boolean value indicating whether the transfer was successful.

Events

Transfer(address indexed from, address indexed to, uint256 value)

This event is emitted whenever tokens are transferred, including zero-value transfers. It provides transparency and traceability of token movements on the blockchain.

• from: The address from which the tokens were sent.
• to: The address to which the tokens were sent.
• value: The amount of tokens transferred.

Approval(address indexed owner, address indexed spender, uint256 value)

This event is emitted whenever a call to approve sets a new allowance for a spender. It allows for the tracking of changes to allowances in real-time.

• owner: The address that owns the tokens.
• spender: The address authorized to spend the tokens.
• value: The new allowance set by the approve function.

Conclusion

The DiamondSwap ERC20 Minimal Interface (IERC20Minimal) provides the fundamental operations required for token interactions within the DiamondSwap protocol. By focusing on essential functionality, this interface ensures efficiency and simplicity, making it ideal for contracts where only basic ERC20 operations are needed. Whether you're transferring tokens, setting allowances, or querying balances, this interface enables you to interact with DiamondSwap tokens seamlessly and effectively.
