Hardhat Principles +- **TypeScript First**: Always use TypeScript for configurations (`hardhat.config.ts`), tests, and deployment scripts. +- **Environment Variables**: Use `dotenv` for private keys and RPC URLs. Never hardcode them. +- **TypeChain**: Always use TypeChain to generate strict typings for smart contracts in your tests. + +## 3. Foundry Principles +- **Dependencies**: Use `forge install libs/openzeppelin-contracts` for dependencies and manage them cleanly via `.gitmodules`. +- **Profiles**: Utilize `foundry.toml` to configure profiles for standard development and optimized CI runs. +- **Scripting**: Use Solidity-based scripts (`forge script`) instead of Bash or JS for deployments to ensure consistency. Use `--broadcast` and `--verify` for production deployments. + +## 4. Verification & Linting +- Always configure Etherscan (or equivalent block explorers like Arbiscan, Basescan) API keys for automatic contract verification. +- Always run `solhint` or `aderyn` or `forge fmt` formats before committing. diff --git a/.agent/skills/smart-contract-testing/SKILL.md b/.agent/skills/smart-contract-testing/SKILL.md new file mode 100644 index 000000000..0ea67b153 --- /dev/null +++ b/.agent/skills/smart-contract-testing/SKILL.md @@ -0,0 +1,30 @@ +--- +name: smart-contract-testing +description: Testing methodologies for EVM smart contracts including unit, integration, and fuzz testing. +--- + +# Smart Contract Testing + +In Web3, testing is not optional; it is the most critical phase before deployment. + +## 1. The Pyramid of Web3 Testing +- **Unit Tests**: Test individual functions and modifiers in isolation. Ensure require/revert statements work properly. +- **Integration Tests**: Test how multiple contracts interact with each other. +- **Invariant Fuzz Testing**: Define properties of the system that must ALWAYS hold true (e.g., "The total supply of tokens must never exceed the max cap") and let a fuzzer (like Foundry's Forge) bombard the contract with random inputs. + +## 2. Foundry / Forge Testing Practices +- **Setup State Properly**: Use a standard `setUp()` function to deploy contracts and set initial balances. +- **Cheatcodes (vm.prank & vm.expectRevert)**: Use `vm.prank(address)` to simulate calls from specific users securely. Use `vm.expectRevert` immediately before a failing call to assert the specific custom error or string. +- **Fuzz Testing**: Write test functions that accept arguments (e.g., `testTransfer(uint256 amount)`). Forge will automatically fuzz these arguments. Use `vm.assume(amount > 0 && amount < totalSupply)` to constrain fuzzing inputs. +- **Event Testing**: Use `vm.expectEmit` to ensure crucial events are being fired on state changes. + +## 3. Hardhat / Chai Testing Practices +- **Fixtures**: Use `@nomicfoundation/hardhat-network-helpers` and `loadFixture` to snapshot the blockchain state. This makes tests run significantly faster. +- **Signers**: Retrieve signers with `ethers.getSigners()` to represent different roles (owner, attacker, user). +- **Match Reverts**: Use `await expect(tx).to.be.revertedWithCustomError(...)`. +- **Time Manipulation**: Use `time.increase()` and `time.latest()` from Hardhat network helpers to test time-dependent logic (e.g., vesting or timelocks). + +## 4. Coverage & Auditing +- Enforce **100% Branch Coverage**. +- Use `forge coverage` or `hardhat coverage`.

Security First +- **Checks-Effects-Interactions (CEI)**: Always implement the CEI pattern to prevent reentrancy attacks. +- **ReentrancyGuard**: Use OpenZeppelin's `nonReentrant` modifier for state-changing external functions that call other contracts. +- **Access Control**: Clearly define `onlyOwner` or generic role-based access control. Do not leave sensitive functions unprotected. +- **No `tx.origin`**: Never use `tx.origin` for authorization; use `msg.sender`. +- **Safe Math**: Avoid integer overflow/underflow. Rely on Solidity ^0.8.0 built-in checks, but be aware of unchecked blocks for gas optimization where safe. + +## 2. Gas Optimization (The Modern Way) +- **Custom Errors**: Use `error InvalidAmount();` instead of `require(..., "Invalid Amount");` to save deployment and runtime gas. +- **Storage vs Memory vs Transient**: Cache storage variables in memory when reading them multiple times. Use `transient` storage (`TSTORE`/`TLOAD`, EIP-1153) for data that only needs to persist for the duration of a single transaction (e.g., reentrancy locks, calculate-and-forward patterns). +- **Calldata**: Use `calldata` instead of `memory` for reference types in external function arguments. +- **Packing Variables**: Group variables of reduced sizes (like `uint128`, `uint64`) next to each other in storage to pack them into a single 256-bit slot. +- **Immutable & Constant**: Use `immutable` for variables set in the constructor and never changed. Use `constant` for fixed values. + +## 3. Architecture & Standards +- **OpenZeppelin Standard**: Inherit extensively from OZ libraries (ERC20, ERC721, ERC1155, AccessControl, Pausable). +- **NatSpec**: Document ALL public/external functions, variables, and custom errors using the `@title`, `@author`, `@notice`, `@dev`, and `@param` tags. +- **Events**: Emit events for *all* critical state changes. +- **Upgradability**: If required, use UUPS or Transparent Proxies securely. Prefer immutable contracts wherever possible. + +## 4. Code Style +- **Naming**: `CamelCase` for contracts, `camelCase` for functions/variables, `UPPER_CASE_WITH_UNDERSCORES` for constants. +- **Modifers**: Keep modifiers simple. Avoid heavy state changes inside them. +- **Layout**: Follow standard layout constraints: State variables, events, errors, modifiers, constructor, functions (external, public, internal, private). diff --git a/.agent/skills/web3-frontend/SKILL.md b/.agent/skills/web3-frontend/SKILL.md new file mode 100644 index 000000000..bca65b2f3 --- /dev/null +++ b/.agent/skills/web3-frontend/SKILL.md @@ -0,0 +1,31 @@ +--- +name: web3-frontend +description: Building modern Web3 frontends with React, Wagmi, viem, and RainbowKit. +--- + +# Web3 Frontend Architecture + +You build intuitive, responsive, and robust Web3 decentralized applications (dApps). + +## 1.

Reading from Contracts +- Use `useReadContract` for single calls. +- Use `useReadContracts` (multicall) when fetching multiple pieces of independent data to reduce RPC load. +- Properly handle `isLoading`, `isError`, and `data` states.
