Solidity

A programming language used by Ethereum to implement Smart Contracts. Runs on the Ethereum Virtual Machine.

• Statically Typed
• Compiled

Boilerplate

pragma solidity ^0.8.26;
 
contract Counter {
    uint256 public count;
 
    // Function to get the current count
    function get() public view returns (uint256) {
        return count;
    }
 
    // Function to increment count by 1
    function inc() public {
        count += 1;
    }
 
    // Function to decrement count by 1
    function dec() public {
        // This function will fail if count = 0
        count -= 1;
    }
}

Development Process

1. Define a contract in the /contracts folder
2. Compile the contract with truffle compile
3. Define a migration in the /migrations folder
4. Ensure truffle-config.js is properly defined
5. Migrate with truffle migrate --reset

Concepts

• Solidity Contract
• Solidity Migration
• Solidity Struct
• Solidity Map
• truffle-config.js
• truffle console
• solc
