Making sudo call using subxt

Question

Good day, I would love to know how to make Sudo calls through subxt library , I can't seem to find a meaningful solution. substrate-api-client has an example on how to make on, but going through the documentation of subxt library, it doesn't show how to do it.

Answer 1

There is a nice test that could be helpful for you to discover how to use sudo:

let call = Call::Balances(BalancesCall::transfer {
    dest: bob,
    value: 10_000,
});

let found_event = cxt
    .api
    .tx()
    .sudo()
    .sudo(call)
    .sign_and_submit_then_watch(&alice)
    .await?
    .wait_for_finalized_success()
    .await?
    .has::<sudo::events::Sudid>()?;
