# PyVax — Python-to-EVM Transpiler & Ecosystem

![PyVax Version](https://img.shields.io/badge/version-0.3.0-blue)
![EVM Target](https://img.shields.io/badge/EVMTarget-Solidity_0.8.27%20Equivalent-green)
![Python Compatibility](https://img.shields.io/badge/Python-3.9%2B-yellow)

PyVax is a powerful compiler toolchain and web ecosystem that allows developers to write EVM (Ethereum Virtual Machine) smart contracts in pure, unadulterated Python. It consists of a production-grade Python-to-EVM transpiler (`avax_cli`), a deployment framework, and an immersive Web3 landing page/documentation platform (`app/`).

---

## 🏗️ Whole-Project Codebase Analysis

The PyVax project is split into two primary domains: the **Core Transpiler CLI** and the **Next.js Web Platform**.

### 1. `avax_cli/` (Core Transpiler & CLI Toolchain)
This directory houses the actual compiler, deployment scripts, and command-line interfaces.
*   **`transpiler.py`**: The heart of PyVax. Evaluates Python ASTs (Abstract Syntax Trees) and maps Python expressions/statements to raw EVM bytecodes. It features a complete `EVMBytecodeGenerator`, a `PeepholeOptimizer`, memory allocators, and ABI generators.
*   **`cli.py`**: A `Typer`-powered CLI with commands for scaffolding (`new`), compilation (`compile`), deployment (`deploy`), and interaction (`call`/`info`).
*   **`deployer.py` / `interactor.py`**: Handles on-chain execution leveraging `web3.py`. Integrates EIP-1559 gas pricing dynamically to adapt to network congestion (primarily targeting Avalanche C-Chain/Fuji).
*   **`wallet.py`**: Manages secure, encrypted keystore files for autonomous agent wallets.
*   **`compiler.py`**: Iterates through `.py` contract files, invokes the transpiler, and outputs compiled artifact JSONs.

### 2. `app/` & `content/` (Web Platform)
The Next.js 14 web platform that powers the PyVax landing page and interactive documentation.
*   **`app/`**: Next.js App Router containing the landing page, immersive 3D WebGL experiences (using Three.js/React Three Fiber), and MDX-powered documentation pages.
*   **`components/`**: Features a rich UI system utilizing Tailwind CSS, Framer Motion for scroll-driven animations, and `ScrollImageSequence` for narrative scrollytelling.
*   **`content/`**: Uses Fumadocs (or equivalent MDX parsing) to manage structured documentation, tutorials, and API references.

## ⚡ Transpiler Features (v0.3.0)

The PyVax transpiler has been aggressively optimized in v0.3.0 to match the gas efficiency and security profiles of **Solidity 0.8.27** and **Huff**. 

### 1. Advanced Gas Optimizations (-15% overall gas reduction)
*   **Binary Search Dispatch**: Automatically upgrades from linear `O(n)` to `O(log n)` selector tree dispatch for contracts with >4 functions. Saves up to **62% gas** per function call compared to the linear fallback.
*   **SLOAD Caching**: Emulates Solidity's CSE (Common Subexpression Elimination) pass #17. Pre-scans ASTs to find state variables read multiple times in a function and caches them in memory (`MLOAD`). Reduces redundant reads from 2,100 gas to **3 gas (99.9% savings)**.
*   **Peephole Optimizer**: Multi-pass bytecode reducer. Implements constant folding (`PUSH5 + PUSH3 + ADD` → `PUSH8`) and identity elimination (`ISZERO / ISZERO` double-negations → `∅`).
*   **Shared Revert Deduplication**: Eliminates bytecode bloat by deduplicating identical `require()` error string encodings into single shared blocks at the bytecode footer (saves ~75 bytes per duplicate message).

### 2. Solidity-Grade Security
*   **Overflow-Safe Arithmetic**: Implicitly protects `ADD`, `SUB`, and `MUL` operations. Validates results on the stack and reverts safely to prevent integer underflow/overflow attacks (Solidity 0.8+ behavior).
*   **Compile-Time Stack Validation**: Tracks EVM stack depth dynamically during compilation across 50+ opcodes. Fails the build immediately if the EVM 1024 stack limit is breached, preventing silent runtime failures.
*   **Isolated Memory Scopes**: Dynamically allocates scratch memory (`0x80+`) per-function to prevent data collision between `emit()`, `require()`, and local variables.

### 3. Comprehensive EVM Feature Parity
*   `msg_sender()`, `msg_value()`, `block_number()`, `block_timestamp()` all natively mapped to opcodes.
*   Full support for Python `while`, `for x in range()`, and `if/elif/else` complex control flows.
*   Native event emissions via `LOG1`-`LOG4`.
*   Complex state storage: Support for dictionaries mapping to EVM `keccak256` slot resolutions.

## 🚀 Installation & CLI Usage

### Prerequisites
*   Python 3.9+
*   Node.js 18+ (for Web dependencies)

### CLI Commands (`pyvax`)

1. **Scaffold a new project:**
   ```bash
   pyvax new my-protocol
   cd my-protocol
   ```
2. **Create a Wallet:**
   ```bash
   pyvax wallet new deployer
   ```
3. **Compile Python Contracts:**
   ```bash
   pyvax compile
   # Outputs optimized ABI and bytecode to /build
   ```
4. **Deploy to Avalanche/EVM:**
   ```bash
   pyvax deploy AgentVault --network fuji
   ```
5. **Call Contract via CLI:**
   ```bash
   pyvax call 0xYourDeployedAddress get_total --view
   ```

## 📝 Writing a PyVax Contract

A PyVax contract is standard, valid Python. It is evaluated via the `ast` module—no Python interpreter is ever deployed on-chain!

```python
from pyvax import Contract, action

class Vault(Contract):
    # State Variables (Slot 0, Slot 1)
    balances: dict = {}
    total_deposits: int = 0

    @action
    def deposit(self, amount: int):
        # Implicitly overflow-safe arithmetic (reverts on overflow)
        self.require(amount > 0, "Amount must be positive")
        
        sender = self.msg_sender()
        self.balances[sender] = self.balances[sender] + amount
        self.total_deposits = self.total_deposits + amount
        
        self.emit("Deposit", sender, amount)

    @action
    def get_balance(self, user: str) -> int:
        return self.balances[user]
```

*(Note: When transpiled using v0.3.0, `self.balances[sender]` caching and binary function routing are automatically injected into the generated bytecode!)*
