ERC20 Token Contract Details

1. ERC20 Token Contract

The ERC20 contract allows users to create and manage their own custom tokens. Each token created has its own:

  • Name and Symbol (e.g., "MyToken" / "MTK")
  • Total Supply assigned at deployment
  • Owner (the creator of the token)
  • Transfer Functionality (Users can transfer tokens between addresses)
  • Minting Capability (Token owner can create more tokens)
  • Ownership Transfer (The owner can transfer token ownership to another user)

2. ERC20 Token Factory Contract

The ERC20TokenFactory contract acts as a factory to deploy new ERC720 tokens. It allows users to:

  • Create a new custom ERC720 token with a chosen name, symbol, and initial supply.
  • Keep track of all tokens they have created.
  • Earn rewards for every 3 tokens they create.

Reward System

  • The contract includes a reward mechanism, issuing 100 reward tokens each time a user creates their 3rd, 6th, 9th (etc.) token.
  • The reward tokens are minted from a predefined reward token contract, which the contract owner can set.

Security & Admin Controls

  • Only the owner of a token can mint more tokens or transfer ownership.
  • The factory owner can change the reward token if needed.

Use Case Scenarios

  • Developers & Entrepreneurs: Create and manage multiple custom tokens for projects, loyalty programs, or governance.
  • Gamification: Users can create tokens for in-game assets, with rewards incentivizing token creation.
  • DeFi & Experimentation: Users can experiment with different tokens and manage their own token ecosystems.

 

ERC20 Dapp Details

The ECS ERC20 Token Manager is a decentralized application (dApp) built with React and Ethers.js. It allows users to interact with an ERC20 token factory contract deployed on the Ethereum blockchain (Sepolia testnet). The app provides a user-friendly interface for managing tokens, authorizing accounts, and performing various token-related operations.

Key Features

1. Wallet Connection

  • Functionality: Users can connect their Ethereum wallet (e.g., MetaMask) to the app.

  • Purpose: This enables the app to interact with the blockchain on behalf of the user.

  • How It Works:

    • The app detects if MetaMask is installed.

    • It requests permission to access the user's wallet address.

    • Once connected, the app displays the user's wallet address and balance.

2. Token Management

  • Functionality: Users can create new ERC20 tokens and manage existing ones.

  • Purpose: This allows users to deploy their own tokens and interact with them.

  • How It Works:

    • Users input the token name, symbol, and initial supply.

    • The app interacts with the token factory contract to deploy a new token.

    • Users can view the deployed token's address, symbol, and total supply.

3. Account Authorization

  • Functionality: Users can authorize or revoke accounts to interact with the token factory.

  • Purpose: This ensures that only authorized accounts can perform certain actions (e.g., creating tokens).

  • How It Works:

    • Users select an account from a dropdown list.

    • They can authorize or revoke the selected account using the token factory contract.

4. Token Operations

  • Functionality: Users can perform token operations such as minting, burning, and transferring tokens.

  • Purpose: This allows users to manage the supply and distribution of their tokens.

  • How It Works:

    • Mint Tokens: Users specify an address and amount to mint new tokens.

    • Burn Tokens: Users specify an amount to burn (destroy) tokens.

    • Transfer Tokens: Users specify a recipient address and amount to transfer tokens.

5. Transaction History

  • Functionality: Users can view their recent wallet transactions.

  • Purpose: This provides transparency and allows users to track their activity on the blockchain.

  • How It Works:

    • The app fetches transaction data from the Etherscan API.

    • It displays details such as transaction hash, sender, recipient, amount, and status.

Technical Details

Technologies Used

  • Frontend: React.js (for building the user interface).

  • Blockchain Interaction: Ethers.js (for connecting to the Ethereum blockchain and interacting with smart contracts).

  • Styling: CSS (for custom styles and theming).

  • APIs: Etherscan API (for fetching transaction data).

Smart Contract

  • The app interacts with a Token Factory Contract deployed on the Ethereum Sepolia testnet.

  • The contract allows users to:

    • Create new ERC20 tokens.

    • Authorize/revoke accounts.

    • Mint, burn, and transfer tokens.

User Flow

  1. Connect Wallet:

    • Users connect their Ethereum wallet to the app.

    • The app displays their wallet address and balance.

  2. Create Token:

    • Users input token details (name, symbol, initial supply).

    • The app deploys a new ERC20 token and displays its details.

  3. Authorize/Revoke Accounts:

    • Users select an account from the dropdown.

    • They authorize or revoke the account using the token factory contract.

  4. Perform Token Operations:

    • Users mint, burn, or transfer tokens using the app's interface.

  5. View Transactions:

    • Users can view their recent wallet transactions fetched from the Etherscan API.

Purpose and Use Cases

  • Token Creation: Users can create their own ERC20 tokens for testing or real-world use.

  • Token Management: Users can manage token supply and distribution.

  • Account Management: Users can control which accounts are authorized to interact with the token factory.

  • Transaction Tracking: Users can monitor their wallet activity on the blockchain.

Conclusion

The ECS ERC20 Token Manager is a powerful and user-friendly dApp for managing ERC20 tokens on the Ethereum blockchain. It combines essential token management features with a sleek and professional design, making it a valuable tool for developers, businesses, and blockchain enthusiasts.
