RunBro Tokens

RunBroToken.sol

Overview

The RunBroToken contract is an ERC20 token with additional features from OpenZeppelin's libraries. It includes ownership control, permit functionality, and voting capabilities.

Inheritance

The contract inherits from the following OpenZeppelin contracts:

  • ERC20: Standard ERC20 token implementation.
  • Ownable: Provides basic authorization control functions.
  • ERC20Permit: Adds permit functionality, allowing approvals via signatures.
  • ERC20Votes: Adds voting capabilities to the token.

Constructor

constructor(uint256 initialSupply)
  • Parameters:
    • initialSupply: The initial supply of tokens to be minted.
  • Description: Initializes the contract by setting the token name to "RunBroToken" and symbol to "RBT". It also mints the initial supply of tokens to the deployer's address.

Functions

safeTransfer

function safeTransfer(address to, uint256 amount) external onlyOwner
  • Parameters:
    • to: The address to transfer tokens to.
    • amount: The amount of tokens to transfer.
  • Modifiers:
    • onlyOwner: Only the contract owner can call this function.
  • Description: Transfers tokens to the specified address. This function is restricted to the contract owner.

_afterTokenTransfer

function _afterTokenTransfer(address from, address to, uint256 amount) internal override(ERC20, ERC20Votes)
  • Parameters:
    • from: The address from which tokens are transferred.
    • to: The address to which tokens are transferred.
    • amount: The amount of tokens transferred.
  • Description: Hook that is called after any transfer of tokens. It ensures that the voting power is updated accordingly.

mint

function mint(address to, uint256 amount) public
  • Parameters:
    • to: The address to mint tokens to.
    • amount: The amount of tokens to mint.
  • Description: Mints new tokens to the specified address. This function can be called by anyone.

_mint

function _mint(address to, uint256 amount) internal override(ERC20, ERC20Votes)
  • Parameters:
    • to: The address to mint tokens to.
    • amount: The amount of tokens to mint.
  • Description: Internal function to mint new tokens. It ensures that the voting power is updated accordingly.

_burn

function _burn(address account, uint256 amount) internal override(ERC20, ERC20Votes)
  • Parameters:
    • account: The address from which tokens are burned.
    • amount: The amount of tokens to burn.
  • Description: Internal function to burn tokens. It ensures that the voting power is updated accordingly.

Notes

  • The contract uses OpenZeppelin's libraries to ensure security and standard compliance.
  • The safeTransfer function is restricted to the contract owner to prevent unauthorized transfers.
  • The _afterTokenTransfer, _mint, and _burn functions are overridden to ensure that the voting power is updated correctly.
