stellar_kt

Multiplatform Stellar SDK

I am currently aiming to support JS, Native and JVM.

What about Soroban?

I am planning to work on Soroban as soon as I finish basic support for creating, signing and submitting transactions.

Why not use the Java library?

The Java library works fine if you are doing server side or android programming. However I would like to share my Kotlin code between server and a web front-end, as Kotlin also targets the Browser.

Examples

create and submit payment transaction

import me.rahimklaber.stellar.base.*
import me.rahimklaber.stellar.base.Asset
import me.rahimklaber.stellar.base.operations.Payment
import me.rahimklaber.stellar.horizon.Server
import me.rahimklaber.stellar.horizon.toAccount

suspend fun main() {
    val horizon = Server("https://horizon-testnet.stellar.org")

    val keypair = KeyPair.fromSecretSeed("SBVLLHTZ5ZV3KZWBBBUNMESYIMK7AEPQJY6FYNCG2PL5LZ5IFCWWSUH2")

    val account = horizon.accounts().account(keypair.accountId).toAccount()

    val tx = transactionBuilder(source = account, network = Network.TESTNET){
        addOperation(
            Payment(destination = account.accountId, asset = Asset.Native, amount = tokenAmount("1"))
        )
    }

    tx.sign(keypair)

    val result = horizon.submitTransaction(tx)

    println(result)
}

prints
