xMEX & Energy


xMEX is the time-locked equivalent of MEX. It has the same value, but for a certain period of time it can’t be bought, sold, or transferred.

All xExchange farm rewards and fees are distributed as xMEX locked for 4 years.


xMEX can be locked from any period ranging between 0 and 4 years, measured in days - more accurately, epochs: 24 hour intervals that begin and end around ~15:30 UTC each day.

xMEX can be unlocked either by waiting for the entire respective period, or at any time but with a penalty ranging from 0 to 80%.

i.e. 100,000 xMEX with 1 years time lock can be converted into 80,000 MEX.


Any xMEX has attributed energy proportional to the locked period.

1 xMEX gives 1 Energy Point per day it is locked for.

Energy Periods


You own 100 xMEX, which are locked for 1 year (360 days).

You will start out with 100*360 = 36000 Energy and after each day, you will have 100 less Energy.

Energy Formula

The amount of an account’s Energy determines the rate of rewards for participating in xExchange.

Simply put, more energy means more rewards:

  • higher APR for farms
  • bigger portion of xExchange fees
  • Metabonding rewards
  • other perks

Each day, as the xMEX gets closer to it’s unlock day, it will lose 1 point.

However, losing energy does not mean you lose your tokens. Your tokens stay the same. You lose energy because your tokens are nearing their unlock date.
