Constructors

Constructor

new NullifierStore(fmd): NullifierStore;

Defined in: @lelantos-org/sdk/dist/wallet/nullifier-store.d.ts:40

Parameters

Parameter	Type
fmd	FmdClient

Returns

NullifierStore

Accessors

size

Get Signature

get size(): number;

Defined in: @lelantos-org/sdk/dist/wallet/nullifier-store.d.ts:58

Nullifiers mirrored so far.

Returns

number

Methods

has()

has(nf): boolean;

Defined in: @lelantos-org/sdk/dist/wallet/nullifier-store.d.ts:56

True if this nullifier was consumed on chain as of the last sync. A stale mirror only ever under-reports, so this never marks a live note spent.

Parameters

Parameter	Type
nf	bigint

Returns

boolean

---

loadState()

loadState(state): void;

Defined in: @lelantos-org/sdk/dist/wallet/nullifier-store.d.ts:43

Parameters

Parameter	Type
state	NullifierStoreState

Returns

void

---

saveState()

saveState(): NullifierStoreState;

Defined in: @lelantos-org/sdk/dist/wallet/nullifier-store.d.ts:44

Returns

NullifierStoreState

---

sync()

sync(opts?): Promise<NullifierSyncSummary>;

Defined in: @lelantos-org/sdk/dist/wallet/nullifier-store.d.ts:50

Fetch new chunks since last sync, fold them into the set, then persist. Idempotent — the tail chunk is re-fetched every sync, so entries already mirrored are dropped by sequence rather than counted twice.

Parameters

Parameter	Type
opts?	NullifierSyncOpts

Returns

Promise<NullifierSyncSummary>

---

withPersistence()

static withPersistence(fmd, persistence): Promise<NullifierStore>;

Defined in: @lelantos-org/sdk/dist/wallet/nullifier-store.d.ts:42

Build a NullifierStore and restore any previously persisted state.

Parameters

Parameter	Type
fmd	FmdClient
persistence	NullifierPersistence

Returns

Promise<NullifierStore>
