### Build and Test Kernel Smart Contract

Source: https://github.com/zerodevapp/kernel/blob/dev/README.md

This snippet outlines the essential commands for setting up, compiling, and testing the Kernel smart contract project. Ensure Foundry is installed before executing these commands.

```Shell
forge install
forge build
forge test
```

--------------------------------

### Foundry Build and Test Commands

Source: https://github.com/zerodevapp/kernel/blob/dev/CLAUDE.md

Provides a list of common `forge` commands for compiling, testing, and debugging smart contracts within the Foundry development environment. Includes options for running specific tests, files, verbose output, and optimized profiles.

```Shell
forge build
forge test
forge test --match-test testFunctionName
forge test --match-path test/Kernel.t.sol
forge test -vv
FOUNDRY_PROFILE=optimized forge test
```

--------------------------------

### Solidity Contract Structure and Standards

Source: https://github.com/zerodevapp/kernel/blob/dev/CLAUDE.md

Provides guidelines for Solidity contract structure, emphasizing gas optimization through immutable variables and adherence to ERC-4337 and ERC-7579 standards. Also recommends using explicit storage slots with assembly for upgradeability.

```APIDOC
Use immutable variables when possible for gas optimization
Follow ERC-4337 and ERC-7579 standards
Use explicit storage slots with assembly for upgradeability
```

--------------------------------

### Solidity Code Formatting Guidelines

Source: https://github.com/zerodevapp/kernel/blob/dev/CLAUDE.md

Defines standard formatting rules for Solidity code, including indentation (4 spaces), brace placement (same line as declaration), and import statements. Emphasizes the use of named imports for clarity and line separators for sectioning.

```Solidity
import {Contract} from "./path.sol";
```

--------------------------------

### Solidity Naming Conventions

Source: https://github.com/zerodevapp/kernel/blob/dev/CLAUDE.md

Outlines standard naming conventions for Solidity contracts, interfaces, functions, private/internal variables, and constants to ensure consistency and readability across the codebase.

```APIDOC
Contracts: PascalCase (e.g. Kernel)
Interfaces: Prefixed with "I" (e.g. IValidator)
Functions: camelCase (e.g. validateUserOp)
Private/internal: underscore prefix (e.g. _executeUserOp)
Constants: ALL_CAPS_WITH_UNDERSCORES
```

--------------------------------

### Solidity Custom Error Handling

Source: https://github.com/zerodevapp/kernel/blob/dev/CLAUDE.md

Specifies the use of custom errors instead of `require` statements for more gas-efficient and informative error handling in Solidity. Recommends the `if-revert` pattern for conditional error triggering.

```Solidity
error InvalidValidator();
if (condition) { revert ErrorName(); }
```
