TRX is the name of the currency used in the TRON network. TRX can be used to vote for a super representative and get bandwidth. The TRX balance in the frozen wallet provides the user with TRON Power (TP) for voting for the Super Representative (SR). In order to keep the network running smoothly, the TRON network only allows each account to start a transaction for free every 10 seconds. The minimum denomination of TRX is SUN, so 1 TRX is equal to 1,000,000 SUN.
