struct ResourceProviders has key {
providers: vector,
}
// Initialize the ResourceProviders globally at the fixed address (RESOURCE_ACCOUNT_ADDR)
public entry fun initialize_providers(signer: &signer) {
let providers = ResourceProviders {
providers: Vector::empty(),
};

    // Use the specified address to move the ResourceProviders
    move_to<ResourceProviders>(signer, providers);
}

i want the function to move to the fixed address RESOURCE_ACCOUNT_ADDR . how to do it

You can create an object with create_named_object and generate object signer with constructor ref. Then move that resource to the object signer.

[kshitijc1506]

If you're using objects, like @ajaythxkur mentioned, you need the object signer. Objects are an upgrade on resource accounts, so this is recommended.

let constructor_ref = object::create_named_object(master, OBJECT_NAME);
let object_signer = object::generate_signer(&constructor_ref);
let extend_ref = object::generate_extend_ref(&constructor_ref);

move_to(&object_signer, ResourceProviders { providers: vector::empty() });
move_to(&object_signer, ObjectController { extend_ref });

If you're using resource accounts, you need the resource account signer capability.

move_to(&resource_acc_signer, ResourceProviders { providers: vector::empty() });

i am using resource account , i have created the ressource account and got this error
. have you an idea how to resolve it and what its causes

[kshitijc1506]

This is coming from retrieve_resource_account_cap, which means you haven't successfully created the resource account and published the package at an address.

[najeh012]

still got the same error , even if the resource account is created and published . if you tell me more how to use the resource_account::retrieve_resource_account_cap(signer, @addressofressourceaccount).

[kshitijc1506]

Just took a look at your code. You can store the resource_signer_cap during module initialization (init_module). Then you can retrieve it (using borrow_global) and generate a signer when you need.

so as a newbie , apperently I misunderstood how to work with resource accounts , from the beginning , if it's possible you drop your discord link .
