The primary purpose of the articles of
confederation was to
(1) provide revenues for the national government
(2) establish the basic framework of the national
government
(3) give the national government the power to
regulate interstate commerce
(4) guarantee a bill of rights to protect citizens
from the national government

The primary purpose of the Articles of Confederation was to 2. establish the basic framework of the national government. It was not intended to provide revenue to the national government; instead, each state was responsible of regulating its own commerce - the national government couldn't even levy taxes. As such, it was also not intended to to give the national government the power to regulate interstate commerce, quite the opposite the Articles wanted a weak national government. Finally, the Bill of Rights did not come into existence until the First Session of Congress following the adoption of the US Constitution in 1787.
