I'm trying to understand the different scenarios where merging an account into another one produces an error case. For the most part, it's all pretty straightforward, but I'm struggling to come up with a scenario that produces the error
The error description reads:
The destination account cannot receive the balance of the source account and still satisfy its lumen buying liabilities.
Keeping in mind a requirement of merging an account requires trade offers and open trustlines to be closed, I interpret this as the source account can't receive XLM that would put the minimum balance of the destination account in a state where it can't satisfy the
(2 + subentry) * 0.5 balance requirement. But if you're adding XLM to the destination, you're only increasing the deficit from that amount and would not ever hit the error scenario.
There's something I'm missing for this error case - does anybody else have a better understanding?
