My bank will seek to make a positive contribution. First, for every customer, there is the enhanced security features of the bank account that everyone benefits. This will include 2FA, Deposit Only account, and stronger debit card protections. These features are just baked into the account, and available to everyone.
As a contribution to the public, my bank will offer at least five $50,000 scholarships to low income students living in Allegheny County and wanting to go to university. The only condition is the college/university must be in the local region. The goal is to keep as much money as possible in the area. This will strengthen the community, and make for a better solution for everyone. Since the scholarship is intended to help those that would otherwise have a hard time to get into higher education, my bank will make at least 5 people in a much better position to go to school than they would have otherwise been.
