extends BaseTaggableObject
implements NewBestBlockListener, TransactionReceivedInBlockListener, PeerFilterProvider, KeyBag, TransactionBag, ReorganizeListener, AddressParser.Strict
```
A Wallet stores keys and a record of transactions that send and receive value from those keys. Using these, it is able to create new transactions that spend the recorded transactions, and this is the fundamental operation of the Bitcoin protocol.

To learn more about this class, read working with the wallet.

To fill up a Wallet with transactions, you need to use it in combination with a BlockChain and various other objects, see the Getting started tutorial on the website to learn more about how to set everything up.

Wallets can be serialized using protocol buffers. You need to save the wallet whenever it changes, there is an auto-save feature that simplifies this for you although you're still responsible for manually triggering a save when your app is about to quit because the auto-save feature waits a moment before actually committing to disk to avoid IO thrashing when the wallet is changing very fast (eg due to a block chain sync). See autosaveToFile(File, long, TimeUnit, WalletFiles.Listener) for more information about this.

  - currentKey
```
public DeterministicKey currentKey(KeyChain.KeyPurpose purpose)
```
    Returns a key that hasn't been seen in a transaction yet, and which is suitable for displaying in a wallet user interface as "a convenient key to receive funds on" when the purpose parameter is KeyChain.KeyPurpose.RECEIVE_FUNDS.

                            throws DeterministicUpgradeRequiresPassword
```
    Upgrades the wallet to be deterministic (BIP32). You should call this, possibly providing the users encryption key, after loading a wallet produced by previous versions of bitcoinj. If the wallet is encrypted the key must be provided, due to the way the seed is derived deterministically from private key bytes: failing to do this will result in an exception being thrown. For non-encrypted wallets, the upgrade will be done for you automatically the first time a new key is requested (this happens when spending due to the change address).
    
    Throws:

  - isDeterministicUpgradeRequired
```
public boolean isDeterministicUpgradeRequired(ScriptType outputScriptType)
```
    Returns true if the wallet contains random keys and no HD chains, in which case you should call upgradeToDeterministic(ScriptType, AesKey) before attempting to do anything that would require a new address or key.

```
    Returns a snapshot of the watched scripts. This view is not live.
  - removeKey
```
public boolean removeKey(ECKey key)
```
    Removes the given key from the basicKeyChain. Be very careful with this - losing a private key destroys the money associated with it.
    
    Returns:
    
    Whether the key was removed or not.

  - importKey
```
public boolean importKey(ECKey key)
```
    Imports the given ECKey to the wallet.
    
    If the wallet is configured to auto save to a file, triggers a save immediately. Runs the onKeysAdded event handler. If the key already exists in the wallet, does nothing and returns false.
  - importKeys
```
public int importKeys(java.util.List<ECKey> keys)
```
    Imports the given keys to the wallet. If autosaveToFile(File, long, TimeUnit, WalletFiles.Listener) has been called, triggers an auto save bypassing the normal coalescing delay and event handlers. Returns the number of keys added, after duplicates are ignored. The onKeyAdded event will be called for each key in the list that was not already present.
  - importKeysAndEncrypt
```
public int importKeysAndEncrypt(java.util.List<ECKey> keys,
                                java.lang.CharSequence password)

  - getWatchingKey
```
public DeterministicKey getWatchingKey()
```
    Returns a public-only DeterministicKey that can be used to set up a watching wallet: that is, a wallet that can import transactions from the block chain just as the normal wallet can, but which cannot spend. Watching wallets are very useful for things like web servers that accept payments. This key corresponds to the account zero key in the recommended BIP32 hierarchy.
  - isWatching
```
public boolean isWatching()
```
    Returns whether this wallet consists entirely of watching keys (unencrypted keys with no private part). Mixed wallets are forbidden.

    Uses protobuf serialization to save the wallet to the given file. To learn more about this file format, see WalletProtobufSerializer. Writes out first to a temporary file in the same directory and then renames once written.
    
    Parameters:
    
    f - File to save wallet

  - setAcceptRiskyTransactions
```
public void setAcceptRiskyTransactions(boolean acceptRiskyTransactions)
```
    Whether or not the wallet will ignore pending transactions that fail the selected RiskAnalysis. By default, if a transaction is considered risky then it won't enter the wallet and won't trigger any event listeners. If you set this property to true, then all transactions will be allowed in regardless of risk. For example, the DefaultRiskAnalysis checks for non-finality of transactions.
    
    Note that this property is not serialized. You have to set it each time a Wallet object is constructed, even if it's loaded from a protocol buffer.
  - isAcceptRiskyTransactions
```
public boolean isAcceptRiskyTransactions()
```
    See setAcceptRiskyTransactions(boolean) for an explanation of this property.
  - setRiskAnalyzer
```
public void setRiskAnalyzer(RiskAnalysis.Analyzer analyzer)
```
    Sets the RiskAnalysis implementation to use for deciding whether received pending transactions are risky or not. If the analyzer says a transaction is risky, by default it will be dropped. You can customize this behaviour with setAcceptRiskyTransactions(boolean).
  - getRiskAnalyzer
```
public RiskAnalysis.Analyzer getRiskAnalyzer()

                                  WalletFiles.Listener eventListener)
```
    Sets up the wallet to auto-save itself to the given file, using temp files with atomic renames to ensure consistency. After connecting to a file, you no longer need to save the wallet manually, it will do it whenever necessary. Protocol buffer serialization will be used.
    
    A background thread will be created and the wallet will only be saved to disk every periodically. If no changes have occurred for the given time period, nothing will be written. In this way disk IO can be rate limited. It's a good idea to set this as otherwise the wallet can change very frequently, eg if there are a lot of transactions in it or during block sync, and there will be a lot of redundant writes. Note that when a new key is added, that always results in an immediate save regardless of delayTime. You should still save the wallet manually using saveToFile(File) when your program is about to shut down as the JVM will not wait for the background thread.
    
    An event listener can be provided. It will be called on a background thread with the wallet locked when an auto-save occurs.
    
    Parameters:
    
    f - The destination file to save to.
    
    delay - How much time to wait until saving the wallet on a background thread.
    
    eventListener - callback to be informed when the auto-save thread does things, or null

```
    Called by the BlockChain when we receive a new filtered block that contains a transactions previously received by a call to receivePending(org.bitcoinj.core.Transaction, java.util.List<org.bitcoinj.core.Transaction>, boolean).
    This is necessary for the internal book-keeping Wallet does. When a transaction is received that sends us coins it is added to a pool so we can use it later to create spends. When a transaction is received that consumes outputs they are marked as spent so they won't be used in future.
    A transaction that spends our own coins can be received either because a spend we created was accepted by the network and thus made it into a block, or because our keys are being shared between multiple instances and some other node spent the coins instead. We still have to know about that to avoid accidentally trying to double spend.
    A transaction may be received multiple times if is included into blocks in parallel chains. The blockType parameter describes whether the containing block is on the main/best chain or whether it's on a presently inactive side chain. We must still record these transactions and the blocks they appear in because a future block might change which chain is best causing a reorganize. A re-org can totally change our balance!
    
    Specified by:
    
    notifyTransactionIsInBlock in interface TransactionReceivedInBlockListener

                    throws VerificationException
```
    Called when we have found a transaction (via network broadcast or otherwise) that is relevant to this wallet and want to record it. Note that we cannot verify these transactions at all, they may spend fictional coins or be otherwise invalid. They are useful to inform the user about coins they can expect to receive soon, and if you trust the sender of the transaction you can choose to assume they are in fact valid and will not be double spent as an optimization.
    
    This is the same as receivePending(Transaction, List) but allows you to override the isPendingTransactionRelevant(Transaction) sanity-check to keep track of transactions that are not spendable or spend our coins. This can be useful when you want to keep track of transaction confidence on arbitrary transactions. Note that transactions added in this way will still be relayed to peers and appear in transaction lists like any other pending transaction (even when not relevant).
    
    Throws:

```
    Given a transaction and an optional list of dependencies (recursive/flattened), returns true if the given transaction would be rejected by the analyzer, or false otherwise. The result of this call is independent of the value of isAcceptRiskyTransactions(). Risky transactions yield a logged warning. If you want to know the reason why a transaction is risky, create an instance of the RiskAnalysis yourself using the factory returned by getRiskAnalyzer() and use it directly.

    Before this method is called, isPendingTransactionRelevant(Transaction) should have been called to decide whether the wallet cares about the transaction - if it does, then this method expects the transaction and any dependencies it has which are still in the memory pool.

```
public boolean isPendingTransactionRelevant(Transaction tx)
                                     throws ScriptException
```
    This method is used by a Peer to find out if a transaction that has been announced is interesting, that is, whether we should bother downloading its dependencies and exploring the transaction to decide how risky it is. If this method returns true then receivePending(Transaction, List) will soon be called with the transactions dependencies as well.

  - isTransactionRelevant
```
public boolean isTransactionRelevant(Transaction tx)
                              throws ScriptException
```
    Returns true if the given transaction sends coins to any of our keys, or has inputs spending any of our outputs, and also returns true if tx has inputs that are spending outputs which are not ours but which are spent by pending transactions.
    
    Note that if the tx has inputs containing one of our keys, but the connected transaction is not in the wallet, it will not be considered relevant.
    
    Throws:

  - receiveFromBlock

                             int relativityOffset)
                      throws VerificationException
```
    Called by the BlockChain when we receive a new block that sends coins to one of our addresses or spends coins from one of our addresses (note that a single transaction can do both).
    This is necessary for the internal book-keeping Wallet does. When a transaction is received that sends us coins it is added to a pool so we can use it later to create spends. When a transaction is received that consumes outputs they are marked as spent so they won't be used in future.
    A transaction that spends our own coins can be received either because a spend we created was accepted by the network and thus made it into a block, or because our keys are being shared between multiple instances and some other node spent the coins instead. We still have to know about that to avoid accidentally trying to double spend.
    A transaction may be received multiple times if is included into blocks in parallel chains. The blockType parameter describes whether the containing block is on the main/best chain or whether it's on a presently inactive side chain. We must still record these transactions and the blocks they appear in because a future block might change which chain is best causing a reorganize. A re-org can totally change our balance!

  - notifyNewBestBlock
```
public void notifyNewBestBlock(StoredBlock block)
                        throws VerificationException
```
    Called by the BlockChain when a new block on the best chain is seen, AFTER relevant wallet transactions are extracted and sent to us UNLESS the new block caused a re-org, in which case this will not be called (the reorganize(StoredBlock, List, List) method will call this one in that case).
    
    Used to update confidence data in each transaction and last seen block hash. Triggers auto saving. Invokes the onWalletChanged event listener if there were any affected transactions.

  - maybeCommitTx
```
public boolean maybeCommitTx(Transaction tx)
                      throws VerificationException
```
    Updates the wallet with the given transaction: puts it into the pending pool, sets the spent flags and runs the onCoinsSent/onCoinsReceived event listener.
    Triggers an auto save (if enabled.)
    Unlike commitTx(org.bitcoinj.core.Transaction) this method does not throw an exception if the transaction was already added to the wallet, instead it will return false
    
    Parameters:
    
    tx - transaction to commit
    
    Returns:
    
    true if the tx was added to the wallet, or false if it was already in the pending pool
    
    Throws:
    
    VerificationException - If transaction fails to verify
  - commitTx
```
public void commitTx(Transaction tx)
              throws VerificationException
```
    Updates the wallet with the given transaction: puts it into the pending pool, sets the spent flags and runs the onCoinsSent/onCoinsReceived event listener. Used in two situations:
    
    When we have just successfully transmitted the tx we created to the network.
    
    When we receive a pending transaction that didn't appear in the chain yet, and we did not create it.
    
    Triggers an auto save (if enabled.)
    Unlike maybeCommitTx(org.bitcoinj.core.Transaction) commitTx throws an exception if the transaction was already added to the wallet.
    Parameters:
    
    tx - transaction to commit
    
    Throws:
    
    VerificationException - if transaction was already in the pending pool

    Returns a set of all WalletTransactions in the wallet.
  - addWalletTransaction
```
public void addWalletTransaction(WalletTransaction wtx)

  - clearTransactions
```
public void clearTransactions(int fromHeight)
```
    Deletes transactions which appeared above the given block height from the wallet, but does not touch the keys. This is useful if you have some keys and wish to replay the block chain into the wallet in order to pick them up. Triggers auto saving.

    Human-readable wallet debugging information
  - getPendingTransactions
```
public java.util.Collection<Transaction> getPendingTransactions()
```
    Returns an immutable view of the transactions currently waiting for network confirmations.
  - earliestKeyCreationTime
```
public java.time.Instant earliestKeyCreationTime()
```
    Returns the earliest creation time of keys or watched scripts in this wallet, ie the min of ECKey.creationTime(). This can return Instant.EPOCH if at least one key does not have that data (e.g. is an imported key with unknown timestamp).
    This method is most often used in conjunction with PeerGroup.setFastCatchupTime(Instant) in order to optimize chain download for new users of wallet apps. Backwards compatibility notice: if you get Instant.EPOCH from this method, you can instead use the time of the first release of your software, as it's guaranteed no users will have wallets pre-dating this time.
    If there are no keys in the wallet, Instant.MAX is returned.
    
    Specified by:
    
    earliestKeyCreationTime in interface PeerFilterProvider
    
    Returns:
    
    earliest creation times of keys in this wallet, Instant.EPOCH if at least one time is unknown, Instant.MAX if no keys in this wallet

```
    Returns time extracted from the last best seen block header, or empty. This timestamp is not the local time at which the block was first observed by this application but rather what the block (i.e. miner) self declares. It is allowed to have some significant drift from the real time at which the block was found, although most miners do use accurate times. If this wallet is old and does not have a recorded time then this method returns zero.

  - getVersion
```
public int getVersion()
```
    Get the version of the Wallet. This is an int you can use to indicate which versions of wallets your code understands, and which come from the future (and hence cannot be safely loaded).
  - setVersion
```
public void setVersion(int version)
```
    Set the version number of the wallet. See getVersion().
  - setDescription
```
public void setDescription(java.lang.String description)
```
    Set the description of the wallet. This is a Unicode encoding string typically entered by the user as descriptive text for the wallet.
  - getDescription
```
public java.lang.String getDescription()
```
    Get the description of the wallet. See setDescription(String)
  - getBalance
```
public Coin getBalance()
```
    Returns the AVAILABLE balance of this wallet. See Wallet.BalanceType.AVAILABLE for details on what this means.
  - getBalance
```
public Coin getBalance(Wallet.BalanceType balanceType)
```
    Returns the balance of this wallet as calculated by the provided balanceType.
  - getBalance
```
public Coin getBalance(CoinSelector selector)
```
    Returns the balance that would be considered spendable by the given coin selector, including watched outputs (i.e. balance includes outputs we don't have the private keys for). Just asks it to select as many coins as possible and returns the total.
  - getBalanceFuture
```
public ListenableCompletableFuture<Coin> getBalanceFuture(Coin value,
                                                          Wallet.BalanceType type)
```
    Returns a future that will complete when the balance of the given type has becom equal or larger to the given value. If the wallet already has a large enough balance the future is returned in a pre-completed state. Note that this method is not blocking, if you want to actually wait immediately, you have to call .get() on the result.
    
    Also note that by the time the future completes, the wallet may have changed yet again if something else is going on in parallel, so you should treat the returned balance as advisory and be prepared for sending money to fail! Finally please be aware that any listeners on the future will run either on the calling thread if it completes immediately, or eventually on a background thread if the balance is not yet at the right level. If you do something that means you know the balance should be sufficient to trigger the future, you can use Threading.waitForUserCode() to block until the future had a chance to be updated.
  - getTotalReceived
```
public Coin getTotalReceived()
```
    Returns the amount of bitcoin ever received via output. This is not the balance! If an output spends from a transaction whose inputs are also to our wallet, the input amounts are deducted from the outputs contribution, with a minimum of zero contribution. The idea behind this is we avoid double counting money sent to us.
    
    Returns:
    
    the total amount of satoshis received, regardless of whether it was spent or not.
  - getTotalSent
```
public Coin getTotalSent()
```
    Returns the amount of bitcoin ever sent via output. If an output is sent to our own wallet, because of change or rotating keys or whatever, we do not count it. If the wallet was involved in a shared transaction, i.e. there is some input to the transaction that we don't have the key for, then we multiply the sum of the output values by the proportion of satoshi coming in to our inputs. Essentially we treat inputs as pooling into the transaction, becoming fungible and being equally distributed to all outputs.
    
    Returns:
    
    the total amount of satoshis sent by us

public Transaction createSend(Address address,

                       throws InsufficientMoneyException,
                              Wallet.BadWalletEncryptionKeyException
```
    Statelessly creates a transaction that sends the given value to address. The change is sent to currentChangeAddress(), so you must have added at least one key.
    
    If you just want to send money quickly, you probably want sendCoins(TransactionBroadcaster, Address, Coin) instead. That will create the sending transaction, commit to the wallet and broadcast it to the network all in one go. This method is lower level and lets you see the proposed transaction before anything is done with it.
    
    This is a helper method that is equivalent to using SendRequest.to(Address, Coin) followed by completeTx(SendRequest) and returning the requests transaction object. Note that this means a fee may be automatically added if required, if you want more control over the process, just do those two steps yourself.
    
    IMPORTANT: This method does NOT update the wallet. If you call createSend again you may get two transactions that spend the same coins. You have to call commitTx(Transaction) on the created transaction to prevent this, but that should only occur once the transaction has been accepted by the network. This implies you cannot have more than one outstanding sending tx at once.
    
    You MUST ensure that the value is not smaller than TransactionOutput.getMinNonDustValue() or the transaction will almost certainly be rejected by the network as dust.
    
    Parameters:
    
    address - The Bitcoin address to send the money to.
    
    value - How much currency to send.
    
    Returns:
    
    either the created Transaction or null if there are insufficient coins.
    
    Throws:
    
    InsufficientMoneyException - if the request could not be completed due to not enough balance.
    
    Wallet.DustySendRequested - if the resultant transaction would violate the dust rules.
    
    Wallet.CouldNotAdjustDownwards - if emptying the wallet was requested and the output can't be shrunk for fees without violating a protocol rule.
    
    Wallet.ExceededMaxTransactionSize - if the resultant transaction is too big for Bitcoin to process.
    
    Wallet.MultipleOpReturnRequested - if there is more than one OP_RETURN output for the resultant transaction.

    Sends coins to the given address but does not broadcast the resulting pending transaction. It is still stored in the wallet, so when the wallet is added to a PeerGroup or Peer the transaction will be announced to the network.

                                   Wallet.BadWalletEncryptionKeyException
```
    Sends coins to the given address, via the given PeerGroup. Change is returned to currentChangeAddress(). Note that a fee may be automatically added if one may be required for the transaction to be confirmed.
    
    The returned object provides both the transaction, and a future that can be used to learn when the broadcast is complete. Complete means, if the PeerGroup is limited to only one connection, when it was written out to the socket. Otherwise when the transaction is written out and we heard it back from a different peer.
    
    Note that the sending transaction is committed to the wallet immediately, not when the transaction is successfully broadcast. This means that even if the network hasn't heard about your transaction you won't be able to spend those same coins again.
    
    You MUST ensure that value is not smaller than TransactionOutput.getMinNonDustValue() or the transaction will almost certainly be rejected by the network as dust.
    
    Parameters:
    
    broadcaster - a TransactionBroadcaster to use to send the transactions out.
    
    to - Which address to send coins to.
    
    value - How much value to send.
    
    Returns:
    
    An object containing the transaction that was created, and a future for the broadcast of it.
    
    Throws:
    
    InsufficientMoneyException - if the request could not be completed due to not enough balance.

                             Wallet.BadWalletEncryptionKeyException
```
    Sends coins to the given address, via the given Peer. Change is returned to currentChangeAddress(). If an exception is thrown by PeerSocketHandler.sendMessage(Message) the transaction is still committed, so the pending transaction must be broadcast by you at some other time. Note that a fee may be automatically added if one may be required for the transaction to be confirmed.
    
    Returns:
    
    The Transaction that was created or null if there was insufficient balance to send the coins.
    
    Throws:
    
    InsufficientMoneyException - if the request could not be completed due to not enough balance.

  - sendTransaction
```
public java.util.concurrent.CompletableFuture<TransactionBroadcast> sendTransaction(SendRequest sendRequest)
```
    Initiate sending the transaction in a SendRequest. Calls sendCoins(SendRequest) which performs the following significant operations internally:
    
    completeTx(SendRequest) -- calculate change and sign
    
    commitTx(Transaction) -- puts the transaction in the Wallet's pending pool
    
    TransactionBroadcaster.broadcastTransaction(Transaction) typically implemented by PeerGroup.broadcastTransaction(Transaction) -- queues requests to send the transaction to a single remote Peer
    
    This method will complete and return a TransactionBroadcast when the send to the remote peer occurs (is buffered.) The broadcast process includes the following steps:
    
    Wait until enough Peers are connected.
    
    Broadcast (buffer for send) the transaction to a single remote Peer
    
    Mark TransactionBroadcast.awaitSent() as complete
    
    Wait for a number of remote peers to confirm they have received the broadcast
    
    Mark TransactionBroadcast.future() as complete
    Parameters:
    
    sendRequest - transaction to send
    
    Returns:
    
    A future for the transaction broadcast
  - waitForConfirmation
```

```
    Wait for a required number of confirmations on a transaction.
    
    Parameters:
    
    tx - the transaction we are waiting for
    
    requiredConfirmations - the minimum required confirmations before completing
    
    Returns:
    
    a future for an object that contains transaction confidence information

```
    Given a spend request containing an incomplete transaction, makes it valid by adding outputs and signed inputs according to the instructions in the request. The transaction in the request is modified by this method.
    
    Parameters:
    
    req - a SendRequest that contains the incomplete transaction and details for how to make it valid.
    
    Throws:
    
    InsufficientMoneyException - if the request could not be completed due to not enough balance.
    
    java.lang.IllegalArgumentException - if you try and complete the same SendRequest twice
    
    Wallet.DustySendRequested - if the resultant transaction would violate the dust rules.
    
    Wallet.CouldNotAdjustDownwards - if emptying the wallet was requested and the output can't be shrunk for fees without violating a protocol rule.
    
    Wallet.ExceededMaxTransactionSize - if the resultant transaction is too big for Bitcoin to process.
    
    Wallet.MultipleOpReturnRequested - if there is more than one OP_RETURN output for the resultant transaction.
    
    Wallet.BadWalletEncryptionKeyException - if the supplied SendRequest.aesKey is wrong.
  - signTransaction
```
public void signTransaction(SendRequest req)
                     throws Wallet.BadWalletEncryptionKeyException
```
    Given a send request containing transaction, attempts to sign it's inputs. This method expects transaction to have all necessary inputs connected or they will be ignored.
    
    Actual signing is done by pluggable signers and it's not guaranteed that transaction will be complete in the end.
    
    Throws:
    
    Wallet.BadWalletEncryptionKeyException - if the supplied SendRequest.aesKey is wrong.
  - calculateAllSpendCandidates
```
public java.util.List<TransactionOutput> calculateAllSpendCandidates()
```

```
    Returns a list of all outputs that are being tracked by this wallet either from the UTXOProvider (in this case the existence or not of private keys is ignored), or the wallets internal storage (the default) taking into account the flags.
    
    Parameters:
    
    excludeImmatureCoinbases - Whether to ignore coinbase outputs that we will be able to spend in future once they mature.
    
    excludeUnsignable - Whether to ignore outputs that we are tracking but don't have the keys to sign for.
  - canSignFor
```
public boolean canSignFor(Script script)
```
    Returns true if this wallet has at least one of the private keys needed to sign for this scriptPubKey. Returns false if the form of the script is not known or if the script is OP_RETURN.
  - calculateAllSpendCandidatesFromUTXOProvider
```
protected java.util.LinkedList<TransactionOutput> calculateAllSpendCandidatesFromUTXOProvider(boolean excludeImmatureCoinbases)
```
    Returns the spendable candidates from the UTXOProvider based on keys that the wallet contains.

  - setUTXOProvider
```
public void setUTXOProvider(@Nullable
                            UTXOProvider provider)
```
    Set the UTXOProvider.
    The wallet will query the provider for spendable candidates, i.e. outputs controlled exclusively by private keys contained in the wallet.
    
    Note that the associated provider must be reattached after a wallet is loaded from disk. The association is not serialized.
  - reorganize
```
public void reorganize(StoredBlock splitPoint,

                throws VerificationException
```
    Don't call this directly. It's not intended for API users.
    
    Called by the BlockChain when the best chain (representing total work done) has changed. This can cause the number of confirmations of a transaction to go higher, lower, drop to zero and can even result in a transaction going dead (will never confirm) due to a double spend.
    
    The oldBlocks/newBlocks lists are ordered height-wise from top first to bottom last.

  - beginBloomFilterCalculation
```
public void beginBloomFilterCalculation()
```
    Description copied from interface: PeerFilterProvider
    
    Called on all registered filter providers before PeerFilterProvider.getBloomFilterElementCount() and PeerFilterProvider.getBloomFilter(int, double, int) are called. Once called, the provider should ensure that the items it will want to insert into the filter don't change. The reason is that all providers will have their element counts queried, and then a filter big enough for all of them will be specified. So the provider must use consistent state. There is guaranteed to be a matching call to PeerFilterProvider.endBloomFilterCalculation() that can be used to e.g. unlock a lock.

  - getBloomFilter
```
public BloomFilter getBloomFilter(double falsePositiveRate)
```
    Gets a bloom filter that contains all of the public keys from this wallet, and which will provide the given false-positive rate. See the docs for BloomFilter for a brief explanation of anonymity when using filters.
  - getBloomFilter
```
public BloomFilter getBloomFilter(int size,

                                  int nTweak)
```
    Gets a bloom filter that contains all of the public keys from this wallet, and which will provide the given false-positive rate if it has size elements. Keep in mind that you will get 2 elements in the bloom filter for each key in the wallet, for the public key and the hash of the public key (address form).
    
    This is used to generate a BloomFilter which can be BloomFilter.merge(BloomFilter)d with another. It could also be used if you have a specific target for the filter's size.

    Used by Peer to decide whether or not to discard this block and any blocks building upon it, in case the Bloom filter used to request them may be exhausted, that is, not have sufficient keys in the deterministic sequence within it to reliably find relevant transactions.
  - addExtension
```
public void addExtension(WalletExtension extension)
```
    By providing an object implementing the WalletExtension interface, you can save and load arbitrary additional data that will be stored with the wallet. Each extension is identified by an ID, so attempting to add the same extension twice (or two different objects that use the same ID) will throw an IllegalStateException.
  - addOrGetExistingExtension
```
public WalletExtension addOrGetExistingExtension(WalletExtension extension)
```
    Atomically adds extension or returns an existing extension if there is one with the same id already present.
  - addOrUpdateExtension
```
public void addOrUpdateExtension(WalletExtension extension)
```
    Either adds extension as a new extension or replaces the existing extension if one already exists with the same id. This also triggers wallet auto-saving, so may be useful even when called with the same extension as is already present.
  - getExtensions
```
public java.util.Map<java.lang.String,WalletExtension> getExtensions()
```
    Returns a snapshot of all registered extension objects. The extensions themselves are not copied.

```
    Deserialize the wallet extension with the supplied data and then install it, replacing any existing extension that may have existed with the same ID. If an exception is thrown then the extension is removed from the wallet, if already present.
    
    Throws:

  - setTransactionBroadcaster
```
public void setTransactionBroadcaster(@Nullable
                                      TransactionBroadcaster broadcaster)
```
    Specifies that the given TransactionBroadcaster, typically a PeerGroup, should be used for sending transactions to the Bitcoin network by default. Some sendCoins methods let you specify a broadcaster explicitly, in that case, they don't use this broadcaster. If null is specified then the wallet won't attempt to broadcast transactions itself.
    
    You don't normally need to call this. A PeerGroup will automatically set itself as the wallets broadcaster when you use PeerGroup.addWallet(Wallet). A wallet can use the broadcaster when you ask it to send money, but in future also at other times to implement various features that may require asynchronous re-organisation of the wallet contents on the block chain. For instance, in future the wallet may choose to optimise itself to reduce fees or improve privacy.
  - setKeyRotationTime
```
public void setKeyRotationTime(@Nullable
                               java.time.Instant keyRotationTime)
```
    When a key rotation time is set, any money controlled by keys created before the given timestamp T will be respent to any key that was created after T. This can be used to recover from a situation where a set of keys is believed to be compromised. The rotation time is persisted to the wallet. You can stop key rotation by calling this method again with null as the argument.
    
    Once set up, calling doMaintenance(AesKey, boolean) will create and possibly send rotation transactions: but it won't be done automatically (because you might have to ask for the users password). This may need to be repeated regularly in case new coins keep coming in on rotating addresses/keys.
    
    The given time cannot be in the future.
    
    Parameters:
    
    keyRotationTime - rotate any keys created before this time, or null for no rotation
  - setKeyRotationTime

```
    A wallet app should call this from time to time in order to let the wallet craft and send transactions needed to re-organise coins internally. A good time to call this would be after receiving coins for an unencrypted wallet, or after sending money for an encrypted wallet. If you have an encrypted wallet and just want to know if some maintenance needs doing, call this method with andSend set to false and look at the returned list of transactions. Maintenance might also include internal changes that involve some processing or work but which don't require making transactions - these will happen automatically unless the password is required in which case an exception will be thrown.
    
    Parameters:
    
    aesKey - the users password, if any.
    
    signAndSend - if true, send the transactions via the tx broadcaster and return them, if false just return them.
    
    Returns:
    
    A list of transactions that the wallet just made/will make for internal maintenance. Might be empty.
    
    Throws:
    
    DeterministicUpgradeRequiresPassword - if key rotation requires the users password.
