Is there any way to call ink! smart contract function in substrate custom pallet?

We've found this answer where bare_call function is based on older version of contract_pallet.

// This ends up calling our contract!
pallet_contracts::Pallet::<T>::bare_call(
    who,
    dest.clone(),
    value,
    gas_limit,
    data,
    debug,
)
.result?;

Now in updated version bare_call function is like this,

pub fn bare_call(
    origin: T::AccountId,
    dest: T::AccountId,
    value: BalanceOf<T>,
    gas_limit: Weight,
    storage_deposit_limit: Option<BalanceOf<T>>,
    data: Vec<u8>,
    debug: DebugInfo,
    collect_events: CollectEvents,
    determinism: Determinism,
) -> ContractExecResult<BalanceOf<T>, EventRecordOf<T>> {}

This is our github repo and right now we are getting this error,

  • Try adding the pallet_contracts::Config to your Config (tight coupling). Aug 24, 2023 at 7:44
  • I have added now getting different error can you please look at

As the error messages clearly state:

arguments to the function are incorrect

This has nothing to do with the change to the bare_call function; two additional arguments (which are not the cause of your problem).

However, it already provides one solution: gas_limit.into(), which converts the integer you give to the Weight struct.

The other two are solved with using a correct BalanceOf<T> type, e.g.:

type BalanceOf<T> = <<T as pallet_contracts::Config>::Currency as Currency<
    <T as frame_system::Config>::AccountId,

I suggest you study the post provided in the comments because it provides all the info you need. The problems you are facing right now are related to providing the correct arguments (working example).
