Impermanent Loss or Unexpected Gain — JETTON / TON Farming

Check out my first article about farming on STON.fi.

Impermanent loss is a situation when one of the tokens (that you’ve provided to the liquidity pool) has significant price changes. I want to show an example of impermanent loss and explain how it works on the example of JETTON/TON liquidity pool on STON.fi.

Why I’ve provided liquidity to the JETTON / TON pool?

I’ve seen an announcement of Jetton farming prolongation on Dec 16th and as usual, I’ve jumped in the first hour.

To be clear in the first 15 minutes since the announcement.

It’s important to note that the highest profit I got on the first day. 2.3 $Jetton in comparison to 10 $Jetton in 15 days (7.7/14 ~ 0.55 Jetton a day). In my opinion, some of the liquidity providers don’t participate in the farming event at the start + it’s less saturated (TVL is less at the start of the farming event).

This farming event is interesting because of:

  • Its time frame (1 year instead of usual 1 month)
  • No lock-up period (instead of 14 days). You can withdraw liquidity at any point in time.

The rewards pool at that point was not looking that significant 9000 JETTON * 0.26 = 2340 TON ~ $5.15k a month. But my thought was to lock up 90 TON equivalent in this farm for a year and check how it would work.

Impermanent Loss or Unexpected Gain?

On Dec 31st JETTON costs 3x+ from my entry point

I saw that JETTON amount in LP started dropping (simultaneously TON amount was growing). The reason behind it is simple — JETTON price increased. During the price change arbitrage bots and users were swapping JETTON and JETTON / TON ratio increased from 0.26 to 0.83.

I’ve provided 44.91 TON + 165.87 JETTON in the liquidity pool

If I’ll hold 165.87 JETTON to this day (31st Dec 2023) I‘ll get 165.87*0.83=137.67 TON. And I will have 137.67+44.91=182.58 TON. Instead of this, I got 77.96 TON + 96.88 JETTON ~ 96.88*0.83+77.96 = 158.37 TON. Impermanent loss in this case is 182.58–158.37 = 24.21 TON.

Why do I consider this an impermanent gain? To be honest I wouldn’t buy JETTON if there was no farming event. That’s why it’s ~ 68 TON (158–90) unexpected gain for me (+10.03 $JETTON = 8.32$TON profit from the farm).

What’s next?

I didn’t understand the reasons behind the price movement (now I can say that JETTON got a license and launched their casino). I’ve fixed all of the “profit” and put it into STON / TON farm.

I could simply withdraw not all of the JETTON / TON from the liquidity pool, but due to the lack of sleep, I’ve withdrawn all of the liquidity. That’s why I’ve spent an extra fee to put the remaining JETTON + TON back.

I’ll try to not touch JETTON / TON in LP and farm. But who knows…
