A CWallet maintains a set of transactions and balances, and provides the ability to create new transactions.
Synopsis
Declared in <wallet/wallet.h>
class CWallet final
: public WalletStorage
, public interfaces::Chain::NotificationsBase Classes
Name |
Description |
Wallet storage things that ScriptPubKeyMans need in order to be able to store things to the wallet database. It provides access to things that are part of the entire wallet and not specific to a ScriptPubKeyMan such as wallet flags, wallet version, encryption keys, encryption status, and the database itself. This allows a ScriptPubKeyMan to have callbacks into CWallet without causing a circular dependency. WalletStorage should be the same for all ScriptPubKeyMans of a wallet. |

|
will be false if ‐fallbackfee=0 |
|
Registered interfaces::Chain::Notifications handler. |
|
Default confirmation target (in blocks) for fee estimation. |
|
When the actual feerate is less than the consolidate feerate, we will tend to make transactions which consolidate inputs. When the actual feerate is greater than the consolidate feerate, we will tend to make transactions which have the lowest fees. |
|
Default output type for newly generated receiving addresses. |
|
Default output type for change outputs. When unset, automatically choose type based on address type setting and the types other of non‐change outputs (see ‐changetype option documentation and implementation in CWallet::TransactionChangeType for details). |
|
Absolute maximum transaction fee (in satoshis) used by default for the wallet |
|
If the cost to spend a change output at this feerate is greater than the value of the output itself, just drop it to fees. |
|
If fee estimation does not have enough data to provide estimates, use this fee instead. Has no effect if not using fee estimation Override with ‐fallbackfee |
|
Number of pre‐generated keys/scripts by each spkm (part of the look‐ahead process, used to detect payments) |
|
Set of Coins owned by this wallet that we won't try to spend from. A Coin may be locked if it has already been used to fund a transaction that hasn't confirmed yet. We wouldn't consider the Coin spent already, but also shouldn't try to use it again. bool to track whether this locked coin is persisted to disk. |
|
note: this is absolute fee, not fee rate |
|
Minimum fee rate to use when creating transactions. |
|
