# TECHNICAL This section describes how PaperMarket is structured under the hood. It gives a high level view of * how the web interface talks to the backend service * how the backend reads market data from Polymarket * how simulation state (accounts, balances, orders, trades and positions) is stored off chain The goal is to give reviewers enough context to understand how the system works technically without exposing implementation details or deployment instructions. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
