You would need to use a bridging protocol due to phantom being on Solana blockchain. If you know which assets specifically, we can point you to the best bridge.

Anything is possible as long as you use the appropriate blockchain or the blockchain you want to use allows it. For example if you use the Eth network, you can transfer any ERC token in between. Of course make sure the coins you want to transfer are available on the wallet itself or in other words, that the wallet allows this specific asset.

A cross chain bridge or using a centralized exchange would be the options, but centralized would have an extra step, so not directly MM to Phantom
