Getting Started

The Altude Client provides the production Core and Gas Station APIs. The API key selects the configured Solana environment, so use a development API key while testing. The Altude SDK uses Kotlin suspend functions for asynchronous network requests.
Ensure these calls are made within a CoroutineScope.

import com.altude.core.model.TransactionSigner
import com.altude.gasstation.Altude
import com.altude.gasstation.AltudeGasStation
import foundation.metaplex.solanapublickeys.PublicKey

class AppTransactionSigner(
    private val wallet: AppWallet
) : TransactionSigner {
    override val publicKey: PublicKey
        get() = wallet.publicKey

    override suspend fun signMessage(message: ByteArray): ByteArray {
        return wallet.signMessage(message)
    }
}

val signer = AppTransactionSigner(appWallet)

AltudeGasStation.init(
    context = context,
    apiKey = "myAPIKey",
    signer = signer,
).getOrThrow()

You can equivalently initialize through the Altude facade:

Altude.setApiKey(
    context = context,
    apiKey = "myAPIKey",
    signer = signer,
).getOrThrow()

Adapt AppWallet to your wallet provider, hardware wallet, or other signing implementation. Your application owns wallet creation, storage, authentication, and key custody. The SDK keeps the configured signer reference only to request local signatures; private keys are not sent to or managed by Altude. Don’t have an API key? Join our Discord and we’ll get you started.
