As part of BitMEX’s efforts to support the MATIC to POL migration, users can now use the Convert function for the POL token on BitMEX.
This means you can now convert Tether into POL (and vice versa) with no fees nor any need to worry about slippage. Additionally, you can deposit, buy and trade POL here.
Users who have yet to withdraw their MATIC (ERC-20) from BitMEX are strongly encouraged to do so as soon as possible. For more details on how you can do so, read our blog.
In the meantime, if you have any questions please contact Support.
