# Function set_contract_sync_cache_invalid

Module: `noir_aztec::oracle::contract_sync`

```rust
pub unconstrained fn set_contract_sync_cache_invalid<let N: u32>(
    contract_address: AztecAddress,
    scopes: BoundedVec<AztecAddress, N>,
)
```

Forces the PXE to re-sync the given contract for a set of scopes on the next query.

Call this after writing data (e.g. offchain messages) that the contract's `sync_state` function needs to discover. Without invalidation, the sync cache would skip re-running `sync_state` until the next block.
