Contract Functions

TokenERC20

A standard ERC20 token contract for representing and managing fungible tokens on the Ethereum blockchain.

Version 1.1.1

TokenERC20 Contract

This contract implements the ERC20 standard, defining functions for transferring, approving, and querying token balances.

Features

  • Transfer tokens between accounts.
  • Approve other contracts to spend tokens on behalf of an account.
  • Retrieve token balances for any account.
  • Query the total supply of tokens.
  • Emit events for transfer and approval operations.

    • Usage

    Deploy this contract to create a new ERC20 token. You can then interact with it using functions like `transfer`, `approve`, and `balanceOf` to manage your tokens.

    Implementation Details

    The contract uses standard Solidity syntax and adheres to the ERC20 interface. It implements the core functionality of token transfers, approvals, and balance queries.

    Best Practices

  • Thoroughly audit the contract code before deployment.
  • Implement appropriate access controls and security measures.
  • Consider using a trusted third-party service for contract deployment and management.

    • Functions

    transfer

    transfer(address recipient, uint256 amount)

    approve

    approve(address spender, uint256 amount)

    transferFrom

    transferFrom(address sender, address recipient, uint256 amount)

    increaseAllowance

    increaseAllowance(address spender, uint256 addedValue)

    decreaseAllowance

    decreaseAllowance(address spender, uint256 subtractedValue)
