An explanation on the Stripe fees for Standard Connect accounts

Stripe Standard Connect accounts have the following schema of fees (assuming that the platform collects a $1 fee):

terminal

                ┌──────────┐
          $10   |          |  $10   ┌───────────────────┐
Customer ─────> | Platform | ─────> | Connected Account |
                |          |        └───────────────────┘          
                └──────────┘ <───────────────┘
                     |              $1 fee
                     |
                     | ($10 · 2.9%) + $0.3 = 0.59$ fee
                     |
                     ˅ 
                 ┌────────┐
                 | Stripe |
                 └────────┘

Here is the equivalent table:

terminal
| Who               | Pays ($)  | Collects ($) | Net ($) |
|-------------------|-----------|--------------|---------|
| Customer          | 10        | -            | -10     |
| Platform          | 10 + 0.59 | 10 + 1       | 0.41    |
| Connected Account | 1         | 10           | 9       |
| Stripe            | -         | 0.59         | 0.59    |
