Best use case

solidity is best used when you need a repeatable AI agent workflow instead of a one-off prompt.

Solidity smart contract development for Ethereum and EVM chains. Use for .sol files.

Teams using solidity should expect a more consistent output, faster repeated execution, less prompt rewriting.

When to use this skill

You want a reusable workflow that can be run more than once with consistent structure.

When not to use this skill

You only need a quick one-off answer and do not need a reusable workflow.
You cannot install or maintain the underlying files, dependencies, or repository context.

# Solidity

Solidity is the primary language for the **Ethereum Virtual Machine (EVM)**. v0.8.28 (2025) focuses on transient storage (`tstore`) and gas optimization via IR.

## When to Use

- **Ethereum/L2s**: Developing for Optimism, Arbitrum, Base.
- **DeFi**: Writing logic for tokens, AMMs, and lending.
- **NFTs**: ERC-721 and ERC-1155 contracts.

## Core Concepts

### Gas

Every operation costs ETH. Optimization is critical.

### Modifiers

Reusable checks. `modifier onlyOwner { ... }`.

### Events

Logging on the blockchain. `emit Transfer(from, to, value)`.

## Best Practices (2025)

**Do**:

- **Use Foundry**: The 2025 standard for testing (Solidity-based tests).
- **Use Custom Errors**: `error InsufficientBalance();` is cheaper than string requires.
- **Use OpenZeppelin**: Don't roll your own crypto/auth logic.

**Don't**:

- **Don't ignore reentrancy**: Use `ReentrancyGuard` or Checks-Effects-Interactions pattern.
