ERC-20 on Polygon is different from ERC-20 on Ethereum main chain, despite having the same address format and naming (ERC-20). BitcoinVN highly suggests that customers should be careful and not using the wrong network.
Currently only main chain transfers on the Ethereum Network are supported on BitcoinVN.
Unfortunately Polygon and Ethereum addresses are the very exact same format which regularly result in unexperienced users mixing up the Polygon (MATIC) network with the Ethereum main chain.
Depositing funds via Polygon (MATIC) will result in loss of funds.
