What did Roger Sherman contribute to the drafting of the Constitution?

Roger Sherman is widely regarded as the founding father of the United States of America because of his contributions to American democracy and lawmaking in general.

Remarkably, he is the only person to sign on the Constitution, Articles of Confederation, the Declaration of Independence, and the Continental Association which are considered the four major documents of United States history.

His contributions to the drafting of the Constitution include:

the doctrine of nullification recommended that states living inside the union have the one-sided, inalienable ideal to void any law made by the national government that could be esteemed illegal.

the united states was shaped based on a general agreement among its individual states. hence, it is inferred that under the hypothesis of invalidation, since the states are the establishment of the union, they have the ability to referee and disprove unlawful laws.
