What it is

XChange is a Java library that abstracts the API differences of 60+ cryptocurrency exchanges (Binance, Kraken, Bitfinex, Coinbase, etc.) behind a single unified interface. Instead of learning each exchange's proprietary REST API, developers write once and swap exchanges by changing configuration. Core capabilities include order placement/cancellation, account balances, market data (tickers, orderbooks, trade history), and real-time WebSocket streaming. Maven monorepo structure: root pom.xml declares 60+ exchange-specific modules (xchange-binance, xchange-kraken, xchange-bitfinex, etc.). Each module at xchange-{exchange}/ contains: (1) src/main/java/org/knowm/xchange/{exchange}/ with…

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

Clone and build:

git clone https://github.com/knowm/XChange.git
cd XChange
mvn clean install

Or use snapshot jars from Maven Central (org.knowm.xchange:xchange-{exchange}:5.2.5-SNAPSHOT). Requires Java and Maven 3.6+. See README for credentials setup per exchange if testing authenticated endpoints.

Daily commands:

XChange is a library, not an application—there is no 'dev server.' To test: (1) Run existing integration tests via Maven: mvn -pl xchange-{exchange} verify (2) GitHub Actions run these automatically on push/PR. To use…

Key cautions & unknowns

• Exchange API authentication requires API keys and secrets specific to each exchange (Binance, Kraken, etc.); tests using authenticated endpoints need valid credentials in environment variables or config files. Some…
• Published-advisory coverage was unavailable for the captured dependencies.
• Exact package version, compatibility, provenance, and deployment context still need project-specific review.
