Liquidity Mining

  • Updated

Overview

Liquidity mining on Perpetual Protocol Curie is currently live. See this blog post for details.

Rewards are distributed on a weekly basis (on Mondays, at 6am UTC), where the amount of PERP earned is proportional to the liquidity you provide to a certain pool. 

As of August 28th, 2022, liquidity mining rewards were adjusted as follows: 27K PERP per week for the ETH market. BTC, BNB, AAVE, FLOW and PERP will remains as 5K PERP per week. Weekly rewards for all other markets were reduced to 3K PERP.

Pool Party (OP Rewards for LPs)

Pool Party rewards may be subject to updates and changes so make sure to follow us on Medium or Twitter for the latest news.

Pool Party is an initiative to incentivize liquidity provision, where PERP liquidity mining rewards are boosted with OP tokens. A total of 5.2 million OP from Perp's allocation will be dedicated to the Pool Party initiative, as outlined in our phase 0 proposal on Optimism's governance forum. 

Provide liquidity across any of our 17 markets to earn OP rewards every week! Check out these guides to get started!

Each week on Monday, OP tokens are distributed amongst the LPs according to the following updated calculation method. 

Calculation Method

As of the week commencing October 16th, Pool Party rewards will be based on:

  • the amount of time the price is within the LP's range (only active liquidity will get rewards), and
  • the concentration of liquidity (where concentrated liquidity will get more rewards).

The amount of time inside the range is based on active tick liquidity. For example, in one second, if you have 30% liquidity in active tick, then your time amount is 0.3 seconds. The more total liquidity amount you provide, the more liquidity amount will be in active tick, and you get more time. The more concentrated range you set, the more liquidity amount in active tick, and you get more time. This is the same logic as maker fee. The calculation method is done in similar manner to the Uniswap v3 Staker contract.

The change was introduced to make the Pool Party liquidity mining more efficient and defend against potential wash trading. For liquidity, tits time amount is calculated by a Uniswap v3 contract. We can get secondsInsidePriceRange of a liquidity position during one week by querying the Uniswap v3 contract.

Formula

\[weeklyRewardProrate = secondsInsidePriceRange / secondsInOneWeek\]

\[weeklyReward = marketWeeklyReward * weeklyRewardProrate\]

Example

  • Alice provides 100 liquidity with a price range of [80, 100] for one week
  • Bob provides 100 liquidity with a price range of [85, 95] for one week
  • The price goes to 90 for one day and then stays at 70 for the rest of the time

For Alice:

  • secondsInsidePriceRange = 30,240
  • weeklyRewardProrate = 30,240 / (60 * 60 * 24 * 7) = 5%
  • weeklyReward = 5,000 * 5% = 250

For Bob:

  • secondsInsidePriceRange = 54,432
  • weeklyRewardProrate = 54,432 / (60 * 60 * 24 * 7) = 9%
  • weeklyReward = 5,000 * 9% = 450

Although Alice and Bob provide the same amount of liquidity and have the same duration in which the price is within their ranges, Bob provides liquidity in a more narrow range and has a larger value for secondsInsidePriceRange for his rewards calculation. 

If instead the price goes to 90 for one day, then to 80 for another day, and then stays at 70 for the rest of the time, Bob's reward calculation will not change but Alice's will. In this case, the secondsInsidePriceRange becomes 60,480 for Alice, the weeklyRewardProrate increases to 10% and the weeklyReward increases to 500. 

The Rewards APR shown on each pool page for an asset estimates the return in OP and PERP tokens for providing liquidity. The lower end estimate indicates the return for providing liquidity across the full price range, while the upper end estimate indicates the return for providing liquidity across a very narrow price range.
