Stellar SDK for Scala
This is the SDK for performing Stellar operations via Scala. It provides the ability to access the Stellar network via Horizon instances to build and submit transactions, query the state of the network and stream updates.
Scala developers may prefer to use this SDK because it provides a more natural API for Scala developers than the official Java SDK
The code throughout this documentation is compiled against Scala 2.13.
Quick-start
Add the jitpack resolver.
resolvers += "jitpack" at "https://jitpack.io"
Then, add the SDK via your dependency management tool.
- sbt
libraryDependencies += "io.github.synesso" %% "scala-stellar-sdk" % "0.21.1"
- Maven
<dependencies> <dependency> <groupId>io.github.synesso</groupId> <artifactId>scala-stellar-sdk_2.13</artifactId> <version>0.21.1</version> </dependency> </dependencies>
- Gradle
dependencies { implementation "io.github.synesso:scala-stellar-sdk_2.13:0.21.1" }
Creating an account on the public test network.
sourceval kp = KeyPair.random
val response = TestNetwork.fund(kp)
Fetching the details of an account.
sourceval account: Future[Account] = network.account(kp).map(_.toAccount)
val nextSeqNo: Future[Long] = account.map(_.sequenceNumber)
Submitting a payment.
sourcefor {
sourceAccount <- network.account(payerKeyPair)
response <- model.Transaction(sourceAccount, timeBounds = Unbounded, maxFee = NativeAmount(100))
.add(PaymentOperation(payeePublicKey.toAccountId, lumens(5000)))
.sign(payerKeyPair)
.submit()
} yield response
