How to get currentReceiveAddress from Bitcoinj wallet without network connection?

Question

We are using bitcoinj to work with bitcoin wallets. Protobuf serialized Wallet body is stored in database as byte array.

As far as I'm concerned, there is no need to connect to bitcoin network to get receive address, because it is calculated somehow from keys, that are stored in Wallet entity.

So my question - is it possible to deserialize protobuf to bitcoinj Wallet entity without any network activity?

Answer 1

fun getBitcoinAddress() {
    val seedCode = "yard impulse luxury drive today throw farm pepper survey wreck glass federal"
    val wallet = Wallet.fromSeed(
        NetworkParameters.fromID(NetworkParameters.ID_MAINNET),
        DeterministicSeed(seedCode, null, "", 0L)
    )
    val changeAddress = wallet.currentChangeAddress()
    val freshAddress = wallet.freshReceiveAddress()
    val currentAddress = wallet.currentReceiveAddress()
    System.out.println(
      "currentReceiveAddress$currentAddress 
       freshAddress$freshAddress 
       changeAddress $changeAddress"
      )**strong text**
    }

Generate A Wallet from mnemonic or seed, then you can get the address. And, yes it is offline
