Write enterprise Bitcoin applications with Spring Boot.
Spring boot starter projects with convenient dependency descriptors for multiple Bitcoin related modules that you can include in your application. Strong focus on integration and regression testing your own application or module. Included are features for representing, transporting, and performing comprehensive calculations and tests with Bitcoin in financial applications and computations.
Note: Most code is still experimental - do not use in production. This project is under active development. Pull requests and issues are welcome. Look at the changelog to track notable changes. Also, developing this project is fun.
Download from Maven Central.
implementation "io.github.theborakompanioni:spring-tor-starter:${bitcoinSpringBootStarterVersion}"<dependency>
<groupId>io.github.theborakompanioni</groupId>
<artifactId>spring-tor-starter</artifactId>
<version>${bitcoinSpringBootStarter.version}</version>
</dependency>The example above imports module spring-tor-starter - you can import any module by its name.
This project contains various modules that can be integrated into your project depending on your requirements.
You can find a small selection in the following table. But there is much more to discover.
| Module | Description |
|---|---|
| bitcoin-jsonrpc-client | Connect to Bitcoin Core via ConsensusJ Bitcoin Core JSON-RPC API client. |
| bitcoin-zeromq-client | Connect to Bitcoin Core via ZeroMq API client. |
| bitcoin-regtest | Integration and regression testing your own application. |
| lnd-grpc-client | Connect to lnd node via LightningJ gRPC API client. |
| xchange-jsr354 | Exchange rates from popular Bitcoin exchanges for your application. |
| spring-xchange | Automatically create and configure XChange beans. |
| spring-tor | Automatically expose your application as Tor Hidden Service. |
| spring-lnurl | Spring Security configurations for authentication with lnurl-auth. |
See modules.md for general information about specific modules.
Besides, that most starter modules also have their own example applications, there are also stand-alone example applications showing basic usage of the functionality provided by these modules.
- bitcoin-autodca: Stacking Sats on Kraken: Auto DCA example application
- bitcoin-exchange-rate: Currency Conversion API example application
- lnd-playground: Lightning Network Playground example application (using lnd)
- lnurl-auth: Spring Security Authentication with
lnurl-authexample application
Example apps can be started with a single command, e.g.:
./gradlew -p incubator/spring-lnurl/spring-lnurl-auth-example-application bootRun- java >=11
- docker
A Bitcoin Core Testcontainer running in regtest mode is started for most examples.
Having access to a Bitcoin Core node running on mainnet is quite useful if you want to try everything.
Optional: A node should publish rawtx and rawblock messages via zmq for some features to work.
./gradlew build -x test./gradlew test integrationTestTests in example application modules or modules that start a lot of docker containers
(modules named "-example-application" or "spring-testcontainer-") are excluded from the
default test phase and must be manually enabled if you want to run them.
To run all tests pass arguments -PexampleTest and -PtestcontainerTest:
./gradlew test integrationTest -PtestcontainerTest -PexampleTestBe aware this might take several minutes to complete (>= 10 minutes).
Gradle is used for checksum and signature verification of dependencies.
# write metadata for dependency verification
./gradlew --write-verification-metadata pgp,sha256 --export-keysSee Gradle Userguide: Verifying dependencies for more information.
Checkstyle with adapted google_checks is used for checking Java source code for adherence to a Code Standard.
# check for code standard violations with checkstyle
./gradlew checkstyleMainSpotBugs is used for static code analysis.
# invoke static code analysis with spotbugs
./gradlew spotbugsMainAll contributions and ideas are always welcome. For any question, bug or feature request, please create an issue. Before you start, please read the contributing guidelines.
