👻 Ghost Trading: Phantom Simulator (Part 1)

Perform "Astral Projection" on the EVM.

This repository accompanies the Part 1 guide on building a local MEV simulation engine. It demonstrates how to simulate complex arbitrage trades locally using eth_call and Phantom Deployments.

💀 The Concept

Most arbitrage bots rely on standard math ($x \cdot y = k$) to calculate profits. They assume every token behaves like USDC. But the chain is full of "Trap Tokens" (Rebase, Fee-on-transfer, Honeypots) that will wreck your PnL.

The Solution: Instead of deploying a contract to test a trade (expensive), or trusting the Router (risky), we perform a Phantom Deployment.

1. We compile our Arbitrage logic (PhantomOut.sol).
2. We construct a deployment transaction but send it via eth_call.
3. The node executes the constructor, runs the swap logic, and returns the result without ever touching the blockchain state.

Zero Gas. Zero Risk.

⚡ Tech Stack

• Bun: High-performance TypeScript runtime (faster than Node).
• Foundry: For writing and compiling the high-performance Solidity logic.
• Ethers.js: For interacting with the local/remote Reth node.
