# Function is_nullifier_pending

Module: `noir_aztec::oracle::nullifiers`

```rust
pub unconstrained fn is_nullifier_pending(
    inner_nullifier: Field,
    contract_address: AztecAddress,
) -> bool
```

Returns `true` if the nullifier has been emitted in the same transaction, i.e. if [`notify_created_nullifier`](/aztec-nr-api/v6.0.0/noir_aztec/oracle/nullifiers/fn.notify_created_nullifier.md) has been called for this inner nullifier from the contract with the specified address.

Note that despite sharing pending transaction information with the app, this is not a privacy leak: anyone in the network can always determine in which transaction a inner nullifier was emitted by a given contract by simply inspecting transaction effects. What *would* constitute a leak would be to share the list of inner pending nullifiers, as that would reveal their preimages.
