So what gALCX does is that it's a tokenized form of the single-sided ALCX staking contract that's found in the farms page. The APR is whatever is on that farm. However, one of the benefits of gALCX is that it auto-compounds, so the APY will be a little higher.
Please be advised, though, that the tentative plan is for gALCX to be deprecated. There has been no formal timeline announced, but the plan is to eventually deprecate gALCX at some point after veALCX is released.
If you have any other questions, may I suggest that you drop in on the discord. There are many helpful people there, and you're likely to get responses to your inquiring much more quickly than here in the forum.
