TONCOIN is absolutely not like POL (Polygon).
POL (Polygon) is based on the EVM (Ethereum Virtual Machine) and involves the concepts of "internal" and "external" transactions.
TONCOIN, which operates on its own blockchain (TON Blockchain), does not have this type of "internal" transaction as found on Ethereum.
On TON, we distinguish between:
External Message = a completely standard transfer.
There are no problematic "internal" transactions like those found on Polygon.
This means that, once Leodex has implemented the fixes on Monday, TONCOIN transfers will proceed normally at 100%, without being considered "internal" transactions.
Leodex will send TONCOIN exactly like any other user on the TON network — it will be a standard transaction. Platforms like Gleec or Fiatleak will detect it immediately, without requiring the "self" to "normal" step you had to perform with POL.
In summary:
POL = requires a "self" to "normal" operation (due to internal EVM transactions).
TONCOIN = direct and standard transfer (because the TON network does not have this internal transaction issue).
