  1. Hi , I Tryign to Write your Code in Substrate but it not work . I face this Error :

    error[E0277]: the trait bound `u128: Currency` is not satisfied
    –> /home/playground/workspace/runtime/src/lib.rs:280:21
    280 | type Currency = Balance;
    | ^^^^^^^ the trait `Currency` is not implemented for `u128`
    note: required by a bound in `pallet_template::Config::Currency`
    –> /home/playground/workspace/pallets/template/src/lib.rs:27:24
    27 | type Currency: Currency;
    | ^^^^^^^^^^^^^^^^^^^^^^^^^ required by this bound in `pallet_template::Config::Currency`

    how can i solve this problem ???
