## What it does

The rule gives Cursor a set of practices for Solidity contracts and React code that handles wallets, providers, and transactions. It asks for explicit function visibility, access control, and NatSpec documentation. Common building blocks such as ownership, multisig, and timelocks should use OpenZeppelin contracts.

For critical contract behavior, it recommends Slither, Mythril, and property-based tests. Gas work focuses on storage layout, function visibility, and unnecessary writes. The guidance also covers pull payments, event logs, defensive error handling, and typed Web3 frontend interactions.

The rule targets `**/*`, while `alwaysApply` is `false`, so it is not forced into every request. In Cursor, place the file at `.cursor/rules/solidity-react-blockchain-apps-cursorrules-prompt-.mdc`. Critical contract paths should have the listed security checks before relying on this guidance.

## Install

### Cursor (native platform)

**Manually: put the files in place**
- File: `.cursor/rules/solidity-react-blockchain-apps-cursorrules-prompt-.mdc` — Frontmatter: description, globs, alwaysApply

### Claude Code

**Manually: put the files in place**
- File: `.claude/rules/solidity-react-blockchain-apps-cursorrules-prompt-.md` — The paths frontmatter field limits the files: move globs from the source into paths

### Codex

**AGENTS.md**
- Codex reads AGENTS.md: paste the rule text there

### GitHub Copilot

**Manually: put the files in place**
- File: `.github/instructions/solidity-react-blockchain-apps-cursorrules-prompt-.instructions.md` — The applyTo field sets which files it applies to: move globs from the source into applyTo

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/rules/solidity-react-blockchain-apps-cursorrules-prompt-.md`

### Cline

**Manually: put the files in place**
- File: `.clinerules/solidity-react-blockchain-apps-cursorrules-prompt-.md`

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/PatrickJS/awesome-cursorrules/tree/HEAD/rules/solidity-react-blockchain-apps-cursorrules-prompt-.mdc

## When to use it
- review a Solidity contract for access-control issues
- inspect storage writes that raise gas usage
- document contract functions with NatSpec
- type wallet and transaction calls in a React frontend
- test critical contract behavior with Slither and Mythril

## Example prompts
- Review this Solidity contract for function visibility, access control, and defensive error handling.
- Find unnecessary storage writes in this contract and suggest gas-focused changes.
- Check the React code that handles wallets and transactions for explicit types and unsafe calls.

Solidity React Blockchain Apps Guidelines

- Prioritize secure Solidity smart contracts with explicit visibility, access control, and clear NatSpec documentation.
- Use established security tooling such as Slither, Mythril, and property-based tests for critical contract behavior.
- Prefer OpenZeppelin contracts for common primitives such as ownership, access control, multisig, and timelocks.
- Optimize gas deliberately by reviewing storage layout, function visibility, and unnecessary writes.
- Use pull-payment patterns, event logging, and defensive error handling for production-grade contracts.
- Keep Web3 frontend code type-safe and explicit when interacting with wallets, providers, and transactions.
```
