pcasafont / elrond-sdk-erdkotlin

Elrond kotlin SDK for interacting with the Elrond Network (in general) and Smart Contracts (in particular).

Elrond Kotlin SDK

This branch is based on the kotlin implementation of Elrond SDK, but closer to the Kotlin ecosystem and style.

Usage

Here is an example for sending a transaction.

val erdSdk = ErdSdk()

// Create a wallet from mnemonics
val wallet = createWalletFromMnemonic("...", 0)

// Get information related to this address (ie: balance and nonce)
val account = erdSdk.getAccount(wallet.publicKeyHex.asHexAddress())

// Get the network informations
val networkConfig = erdSdk.getNetworkConfig()

// Create the transaction object
val transaction = Transaction(
    sender = account.address,
    receiver = "...".asHexAddress(),
    value = 1000000000000000000.toBigInteger(), // 1 xEGLD
    data = "Elrond rocks !",
    chainID = networkConfig.chainID,
    gasPrice = networkConfig.minGasPrice,
    gasLimit = networkConfig.minGasLimit,
    nonce = account.nonce
)

// Send transaction.
// Signature is handled internally
val sentTransaction = erdSdk.sendTransaction(transaction, wallet)
println("Transaction: ${sentTransaction.txHash}")

Configuration

// default value is ProviderUrl.DevNet
val erdSdk = ErdSdk(ProviderUrl.MainNet)
