Solidity is the primary language for writing smart contracts on the Ethereum blockchain. It's a statically-typed, object-oriented language with syntax inspired by JavaScript. Here's a quick overview to get started:
📌 Key Features
- Contract-centric: Focuses on defining state, functions, and events
- Supports inheritance: Enables code reuse through contract inheritance
- Built-in support for Ethereum: Native types like
address
,uint
, andbytes
- Security-focused: Tools like
require()
andrevert()
for error handling
🧾 Basic Syntax Structure
pragma solidity ^0.8.0;
contract MyContract {
// State variables
uint public myVariable = 10;
// Functions
function setVariable(uint _newValue) public {
myVariable = _newValue;
}
}
🔍 Best Practices
- Always validate inputs using
require()
❗ - Use
view
orpure
for non-state-changing functions 🔍 - Follow EIP-1283 for gas-efficient coding
- Test thoroughly with Truffle or Hardhat
