IMD Bridge ⇄

The bridge takes no percentage — the only cost is one fixed LayerZero message fee, so small amounts are expensive and large ones are nearly free. Amounts are truncated to 6 decimals by the OFT itself; anything finer is dropped, and this page rounds down for you before sending.
Both contracts enforce only 60,000 gas on the far side, which is not enough to pay an address holding none of the token yet — that delivery reverts and the transfer sits pending. This page buys 200,000 more, for about a third of a cent.
