Polygon deposits and withdrawals are only supported for ERC20 tokens on the Ethereum network.
Please be informed that deposits and withdrawals from the Polygon network are not supported.
As of now, we are unable to process any recovery of deposits accidentally transferred via the Polygon network.
Regarding deposits and withdrawals via the Polygon network, we are considering future measures.
