Here is the link to my Money Box smart contract which I am trying to get the total balance of the specified token [https://github.com/sway-gang/money-box/blob/total\_balance\_of/src/main.sw](https://github.com/sway-gang/money-box/blob/total_balance_of/src/main.sw) ```auto fn total_balance_of(asset_id: ContractId) -> u64 { balance_of(contract_id(), asset_id) } ``` But when I run this contract with following test I keep getting 0 as token balance [https://github.com/sway-gang/money-box/blob/total\_balance\_of/tests/local\_tests/main\_test.rs](https://github.com/sway-gang/money-box/blob/total_balance_of/tests/local_tests/main_test.rs) ```auto let contracts = [Bech32ContractId::from(contract_id)]; let total_balance = methods .total_balance_of(contract_id) .set_contracts(&contracts) .simulate() .await .unwrap(); println!("total_balance: {}", total_balance.value); ``` Please help) ---

Your link doesn’t work for me, is that a public repo? ---

~~Thanks! This looks like a type mismatch, as `contract_id()` returns a `ContractId`, so the key you provided is of type `(ContractId, ContractId)` instead of `(Address, ContractId)`. You might want to consider using `Identity` instead, which can be either an `Address` or `ContractId`: [Blockchain Types - The Sway Programming Language](https://fuellabs.github.io/sway/v0.33.0/book/basics/blockchain_types.html#identity-type)~~ ---

Tried using identity, same result. ```auto let identity = Identity::ContractId(contract_id); let total_balance = methods .total_balance_of(identity) .set_contracts(&cotarcts) .simulate() .await .unwrap(); println!("total_balance: {}", total_balance.value); ``` And the address cannot be used as an argument because of a compilation error ```auto error --> /Users/alexey/projects/fuel/money-box/src/main.sw:93:35 | 91 | 92 | // }; 93 | balance_of(contract_id(), asset_id) | ^^^^^^^^ Mismatched types. expected: ContractId found: Address. help: The argument that has been provided to this function's type does not match the declared type of the parameter in the function declaration. 94 | } 95 | } | ____ ``` ---

My apologies, the type is not the issue here. It is actually just the order of the arguments passed to the `balance_of` function. It should be `balance_of(asset_id, contract_id())` . You can see the full code for this function here: [sway/context.sw at 949dfb98bd8ad0d89c5a59a33b391892e665a760 · FuelLabs/sway · GitHub](https://github.com/FuelLabs/sway/blob/949dfb98bd8ad0d89c5a59a33b391892e665a760/sway-lib-std/src/context.sw#L14) ---

That’s works Thanks a lot!!! ❤ ---

It would be better to use `this_balance(asset_id)` in that case ---
