Solidity-Solidity smart contract generator

Example

contract Voting { mapping(address => bool) public hasVoted; function vote() public { require(!hasVoted[msg.sender]); hasVoted[msg.sender] = true; } }

Scenario

Used in a decentralized voting system toSolidity Overview and Functions track which addresses have already voted, ensuring that each address can vote only once. Storage is permanent and exists across transactions, maintaining the integrity of voting history.

Example

contract Ownable { address public owner; modifier onlyOwner { require(msg.sender == owner); _; } } contract Token is Ownable { function mint() public onlyOwner { /* mint logic */ } }

Scenario

Useful in building upgradeable and modular systems. In this example, contract reusability allows access control to be handled in one base contract (`Ownable`), reducing duplication and improving maintainability across many contracts such as DeFi protocols and NFT platforms.

Example

event FundsDeposited(address indexed user, uint256 amount); function deposit() public payable { emit FundsDeposited(msg.sender, msg.value); }

Scenario

Crucial for off-chain indexing and transparency. This is commonly used in dApps (decentralized apps) like decentralized exchanges, enabling frontend applications or oracles to react to blockchain activities by subscribing to these emitted events.
