Update `Account` to also represent application accounts.
Prevent excessive stack usage by nested futures.
Remove normalization of owners, and use `AccountOwner` directly.
Update the `balances` map to support applications.
Prepare to allow the helpers to be used by a new integration test module. Also, rename the test helpers for consistency.
Ensure that applications can transfer from their accounts, from the shared chain account, and from the signer's account.
Ensure that applications can claim from their accounts or from the signer account in remote chains.
Prepare to use it in property tests.
Ensure applications can read the chain balance.
Ensure applications can read the balances of individual accounts.
Ensure applications can read a list of all account balances.
Ensure applications can read a list of all accounts.
The system API should fallback and return zero in that case.
Ensure that execution fails with the appropriate error.
Ensure that execution fails with the appropriate error.
Allow tests to create a dummy context to test queries.
Ensure applications can read the chain balance.
Allow the helper function to be used in other tests.
Ensure applications can read the balances of individual accounts.
Ensure applications can read a list of all account balances.
Ensure applications can read a list of all accounts.
The system API should fallback and return zero in that case.
Simplify the code to generate the error. Co-authored-by: Andreas Fackler <[email protected]> Signed-off-by: Janito Vaqueiro Ferreira Filho <[email protected]>
The runtime API should be deterministic, so the returned lists of accounts must be sorted. Co-authored-by: Andreas Fackler <[email protected]> Signed-off-by: Janito Vaqueiro Ferreira Filho <[email protected]>

Motivation
Applications may hold tokens from Fungible Token applications, however, they can't hold native tokens. This creates some incompatibility, and also makes it harder to support some scenarios, like automatic market makers using native tokens.
Proposal
Allow applications to hold native tokens, and to transfer them.
Update the on-chain
balancesto useAccountOwneras its key, instead ofOwner. This allows applications to have balances. Also updateAccountto useAccountOwnerinstead ofOwner.Update the WIT interface so that the system APIs can transfer, claim and query application balances.
Test Plan
Unit tests were added to test the runtime APIs using application accounts.
