# PaperDrill

> PaperDrill is a live paper-trading exchange simulator with a real matching engine, live order book, and REST/WebSocket API — built for developers who want to trade or test bots without real money or KYC.

PaperDrill runs BTC/USD, ETH/USD, and SOL/USD spot markets with price-time priority matching, persistent simulated balances, and real-time market data. It is free, browser-based, and designed as a sandbox for learning exchange mechanics and building trading strategies.
