Solidity LSP

---

name: solidity-lsp

description: Solidity language server providing smart contract development support including compilation, linting, security analysis, and code intelligence for .sol files. Use when working with Ethereum smart contracts, Substrate pallets, or any Solidity code that needs compilation, security checks, gas optimization, or code navigation. Essential for ClawChain pallet development.

# Solidity LSP

Solidity language server integration providing comprehensive smart contract development support through solc (Solidity compiler) and solhint (linter).

Capabilities

Installation

Install Solidity compiler and linter:

# Solidity compiler
npm install -g solc

# Solidity linter
npm install -g solhint

Verify installation:

solcjs --version
solhint --version

Usage

Compile Solidity Contract

solcjs --bin --abi contract.sol

Compile with optimization:

solcjs --optimize --bin --abi contract.sol

Lint Contract

Run solhint on a file:

solhint contracts/MyContract.sol

Run on entire project:

solhint 'contracts/**/*.sol'

Security Analysis

solhint includes security rules by default. For advanced security analysis, consider:

# Install slither (requires Python)
pip3 install slither-analyzer

# Run security analysis
slither contracts/

Configuration

solhint Configuration

Create `.solhint.json` in project root:

{
  "extends": "solhint:recommended",
  "rules": {
    "compiler-version": ["error", "^0.8.0"],
    "func-visibility": ["warn", {"ignoreConstructors": true}],
    "max-line-length": ["warn", 120],
    "not-rely-on-time": "warn",
    "avoid-low-level-calls": "warn",
    "no-inline-assembly": "warn"
  }
}

Hardhat/Foundry Integration

For full development environments, see `references/frameworks.md`.

Integration Pattern

When developing smart contracts:

1. **Write**: Edit Solidity code

2. **Lint**: Run `solhint` to catch issues early

3. **Compile**: Use `solcjs` to verify compilation

4. **Analyze**: Run security tools before deployment

5. **Test**: Write comprehensive unit tests
