ChainVeil is a Rust-powered C2 Framework for generating custom JavaScript payloads that interact with Ethereum. ChainVeil is designed to demonstrate how threat actors leverage decentralized technology for its flexibility and robustness.

---

⚡ Features

• Rust-powered payload creation — ultra-lightweight, fast, and cross-platform.
• Custom JS generation — generate JavaScript that fetches data from Ethereum addresses.
• Portable execution — compile a single binary or run via script so no heavy dependencies.
• Community templates — contribute your own templates to expand functionality.

🛠 Usage

1. Clone the repository:

git clone https://github.com/KOSEC-LLC/ChainVeil.git
cd ChainVeil

2. Build the Rust binary:

cargo build --release

3. Run ChainVeil with your Ethereum address:

./target/release/ChainVeil \
  --content "0x000000000000000000000000000000000000dEaD" \
  --template templates/downloader.js \
  --output output/example.js \
  --payload payloads/payload.ps1

4. Open or run the generated output/example.js in your JS environment to fetch and log data.
