Useage

const _buf2hex = (buffer) => { // buffer is an ArrayBuffer
    return Array.prototype.map.call(new Uint8Array(buffer), x => ('00' + x.toString(16)).slice(-2)).join('');
}
const server = new StellarSdk.Server('https://horizon.stellar.org')
const account = await server.loadAccount(address)

// Operation
const operationXdr = StellarSdk.Operation.createAccount({
    destination: toAddr,
    startingBalance: amount
})

// Builder
const transactionBuilder = new StellarSdk.TransactionBuilder(account, { 
    fee: StellarSdk.BASE_FEE,
    networkPassphrase: StellarSdk.Networks.TESTNET
})
.addOperation(operationXdr)
.setTimeout(300)
.build()

const unsignedTx = _buf2hex(transactionBuilder.signatureBase())

const transactionJson = {
    unsignedTx: unsignedTx,
    fee: StellarSdk.BASE_FEE
    path: `m/44'/148'/0'`,
}

var result
try {
    result = await DcentWebConnector.getStellarSignedTransaction(transactionJson);    
} catch (e) {
    console.log(e)
    result = e
