Just noticed that there's a new Steemit Dev Group community with this relevant post - TRX integration with steemit wallet.

Recently, we are trying to add TRX into steemit wallet. Those feature will not affect steemit community or ecosystem since we do not replace steem blockchain. Again, you guy still can do whatever you want on the steem blockchain. Beside, any steemit user can gain extra TRX reward, which may increase your outcome by voting or posting .
