How to

1. Add it in your root build.gradle at the end of repositories:

allprojects {
    repositories {
        ...
        maven { url 'https://jitpack.io' }
    }

Example

Transfer lamports

val api = RpcApi(RpcClient(Cluster.TESTNET))
val fromPublicKey = PublicKey("QqCCvshxtqMAL2CVALqiJB7uEeE5mjSPsseQdDzsRUo")
val toPublicKey = PublicKey("GrDMoeqMLFjeXQ24H56S1RLgT4R76jsuWCd6SvXyGPQ5")
val lamports = 3000L

val signer = Account("4Z7cXSyeFR8wNGMVXUE1TwtKn5D5Vu7FzEv69dokLv7KrQk7h6pu4LF8ZRR9yQBhc7uSM6RTTZtU1fmaxiNrxXrs")

val transaction = Transaction()
transaction.addInstruction(transfer(fromPublicKey, toPublicKey, lamports))

val signature = api.sendTransaction(transaction, signer)

Get balance

val api = RpcApi(RpcClient(Cluster.TESTNET))

val balance = api.getBalance(PublicKey("QqCCvshxtqMAL2CVALqiJB7uEeE5mjSPsseQdDzsRUo"))
