As you may already know, the TRON (TRX) main network will be launched on May 31, 2018. What does this mean for TRON?
Simply put, the introduction of TRON’s main network means that TRON will give up its ERC20 identity and leave the Ethereum platform.
What does that mean if you own Tron (currently still ERC20 token)? What do you need to do to migrate your TRX to Tron’s main network?
Exchanges perform migration
The easiest and most convenient way to migrate your TRX from Ethereum (ERC20 token) to the new Tron Mainnet is to leave your TRX on an Exchange such as Binance or Bittrex during this time around May 31, 2018, since these exchanges migrate automatically.
So make sure that you have saved your TRX on an Exchange before May 31st.
