0. Capture OS

This is the entry point to understanding Capture OS: what it is, how it’s built, and how you’re supposed to use it.

0.1 What is Capture OS (ex-SpreadNet)?

Capture OS is a Solana arbitrage operating system.

At its core, it does one thing extremely well:

Continuously scan Solana DEXs for price inefficiencies and surface them in a clean, machine- and human-readable way — without ever touching your funds.

The stack is split in layers:

• Capture Engine The open-source detection core (the capture repo). It fetches quotes from multiple Solana DEXs/aggregators, normalizes them, calculates net spreads, filters noise, and outputs ranked opportunities in real time.

• Capture Terminal The interface layer. This includes:

  • The CLI terminal you run locally.

  • The hosted live feed (web UI) that shows a real-time stream of opportunities and system stats.

• Capture Bot (optional product layer) An automated execution engine that sits on top of Capture Engine, adds risk management and MEV-aware routing, and actually sends transactions. This is not part of the open-source repo; it’s the “automation on top”.

So the mental model:

• Capture Engine → finds edges

• Capture Terminal → shows edges

• Capture Bot → acts on edges

You can use any subset of these depending on who you are and what risk you want to take.
