At the risk of been downvoted: you cant. It is impossible.

Even if you had $30 billion, and your goal was to guarantee the distribution of only $1 to everyone, it still wouldnt occur with all the excess.

When you factor in corruption, fraud, inadequate infrastructure, and vague defining of the parameters.

Just think of the edge cases to understand why this couldnt be achieved:

1. A subset of the population will ACTIVELY reject your attempt to give them $1, as they will consider it spam, anti-god, conspiracy or one of hundreds of other reasons (look at recent world events to see that there is always a % of the pop on the other side)

2. A subset of the population will ACTIVELY attempt to fraud you for extra money. Claim multiple times, or claim on behalf of other people (their dead grandmother)

3. A subset of the population will ACTIVELY use corruption for extra money. Consider state actors such as North Korera, or third world countries with poor controls

I could go on - but those 3 reasons alone are enough edge cases to start with.

Not to mention having to keep going because babies are born and the money can't be delivered instantaneously...

Not to mention getting anything into the hands of off-the-grid homesteading hermits – or even finding them to begin with.

(Or getting a buck into the hands of every Sentinelese)

I mean, that's probably fairly easy but whoever does it better be really committed to this project.

OP here: I don't see why you'd be downvoted for this, it's a fair point! I agree with each of your three points, and in response I'll change the requirements a bit:

How can I get 1 dollar to as many people as possible, while spending the least amount of money on transactional costs or fighting fraud/corruption?

I think all of the edge cases you named above can be dealt with given this new requirement. Some fraud and corruption will happen for sure, just like with any financial transaction anywhere in the world. I would say that fighting fraud/corruption is only worth it, if the cost of fighting it is less than what you'd lose to it if left unchecked. A dead grandma will be too expensive to disprove, but someone making thousands of fake personas must be detectable somehow, such as re-using the same bank account or adress a thousand times.

It would be interesting to estimate the millions of people in the world that are likely to be completely inaccessible and would never get a dollar.

For example, North Korea. The government would insist on running the distribution itself, and because they are always in dire need of foreign cash, most or all of it would be diverted to some other purpose.
