Crypton

​
What is Crypton?

Crypton is a unified API that aggregates real-time crypto derivatives data from 23+ exchanges into a single, consistent interface. Think of it as a Coinglass alternative you can self-host and extend.

​

Key Features

  • Sub-second polling — DashMap concurrent cache with ~2000 symbols
  • Funding rate normalization — 1h rates (Hyperliquid, dYdX) auto-converted to 8h equivalent
  • Cross-exchange arbitrage — Real-time funding rate spread detection with APR calculation
  • 15 API families — One implementation covers multiple exchanges (Binance family covers Binance, Binance US, BingX, Binance COIN-M)
  • Pure Rust indicators — RSI, MACD, Bollinger Bands, ATR, EMA computed without external dependencies
  • Gzip compression — All API responses are gzip-compressed automatically for faster transfers
  • Real-time WebSocket — Topic-based subscriptions with CloudEvents 1.0 envelopes, wildcard patterns, sequence resume, and token auth
  • 137 unit tests — Comprehensive coverage across all exchange parsers, indicators, and cache logic

​
Quick Start

# Clone and build
git clone https://github.com/alt0x17/crypton
cd crypton
cargo build --release

# Run (default port 3177)
./target/release/crypton

# Test it
curl http://localhost:3177/v1/overview?symbol=BTC
REST endpoints require no authentication. WebSocket connections require a token (?token=secret). All REST responses are gzip-compressed and wrapped in {status, timestamp, data} envelope.
