It has now been approximately three days since the DEC token was added to the Uniswap DEX and we are thrilled to see how much liquidity and volume has gone through the exchange in such a short time! We also wanted to take this opportunity to answer a few common questions that have come up.
You can find the original announcement post with more details about the Uniswap listing and LP rewards that Splinterlands will be providing here: @splinterlands/dec-is-on-uniswap
Many of the questions that have come up since the announcement have been around exactly how the LP rewards will be calculated. Whenever anyone provides liquidity to the Uniswap pool, they will receive a custom ERC-20 token in their Ethereum wallet that represents their contribution to the pool. When you remove liquidity from the pool, you send those tokens back to Uniswap in exchange for your funds.
This provides an easy way to determine the amount of liquidity provided by each Ethereum wallet address as a percent of the total at any point in time. You can see it at the following link which shows the current list of holders of the ETH-DEC Uniswap LP token: https://etherscan.io/token/0xf274d21e16cd7fa726585c6b12f817b81f7ced22#balances
We will be taking a snapshot of that list every day at approximately 2:00 PM ET / 18:00 UTC and using that to determine the total liquidity provided by each participating address over each 30 day period for land plot rewards and the full 90 day period for the raffle ticket rewards.
At the time of writing, there is approximately $128,000 of liquidity in the pool in total. You can see at the above link that the Splinterlands wallet (0x547f5b802486e881d4805aa9605e3d67e52a8904) currently provides ~37.28% of the total pool. Since Splinterlands will not be taking any of the rewards, this amount should be subtracted from the total pool supply when calculating rewards.
After subtracting the Splinterlands portion, that leaves approximately $80,000 contributed to the pool from players. Assuming that remains the same throughout the full 30 day period (which started on Oct. 3rd, 2020 and will go through Nov. 2nd, 2020) then players will receive one free plot of land for approximately each $80 ($40 of DEC and $40 of ETH) worth of liquidity (representing 0.1% of the total) contributed to the pool over that time period.
The full retail price of each land plot will be $20, but even using the planned first presale price of $10 / plot, that provides a ~12.5% return on the funds provided to the liquidity pool per month, which comes to ~150% annualized returns. Please remember that this incentive will go for 90 days in total, so for each 0.1% of the total pool contributed over the 90 day period you will receive three free land plots in total - one each 30 days.
If that wasn't enough incentive, each 0.1% of the pool provided over the full 90 day period will also receive 100 free raffle tickets which will be tradeable tokens and can earn the holders some really valuable prizes. More details on the raffle will be available when the land presale details are announced in the next couple of weeks.
Shortly after each of the three 30-day periods (but not before the first land presale goes live) the land plot rewards will be available to claim by anyone who has participated in the liquidity pool during the period. Plots will be represented by a fungible token that can be transferred and traded and will be available on the Hive Engine exchange.
Raffle ticket rewards will be able to be claimed in a similar manner shortly after the full 90 day period is completed.
Once again, many more details about the land presale plot tokens and raffle tokens will be available when the land presale details are announced in the next couple of weeks.
We also wanted to be clearer about the risks involved with providing liquidity to the Uniswap pool. When you provide liquidity initially, you are required to add an equal dollar amount of both DEC and ETH tokens based on the current pricing of the Uniswap pair. Then, as people swap DEC for ETH and vice versa, the amount of each token in the pool will change.
This means that the amount of DEC and ETH you will receive when you withdraw your liquidity from the pool may change significantly from the amount you put in. You will either receive more DEC and less ETH or less DEC and more ETH, depending upon the amount of each token in the total pool at the time you withdraw. Additionally, the prices in USD of both tokens may vary significantly between the time you commit your funds to the pool and the time you remove them.
As we mentioned in the original announcement post, Splinterlands does not assume any responsibility, nor can we issue any refunds for loss of funds or any other issues relating to the use of Uniswap or transactions on the Ethereum network. Please make sure you know what you are doing, and if you are unsure, please ask for help in the Splinterlands Discord server.
Going forward, the price feed for the DEC token used within the game (primarily used for purchases of cards on the market) will be based on the price of the ETH/DEC Uniswap pair instead of the price on Hive Engine.
Due to its use of liquidity pools and the relatively significant amount of liquidity available, the pricing on Uniswap should be much less volatile than that on Hive Engine, which should help to alleviate a number of issues that have come up in the past.
Recently there have been a number of instances in which players are using Splinterlands Credits in order to purchase cards from themselves on the market with the sole purpose of acquiring DECs to then sell on various third-party markets. The use of Credits on the market is offered as a convenience to facilitate the purchasing of cards on the market from other players.
Going forward, any accounts found to be using Credits to purchase cards from themselves or from other accounts that they are believed to control will be blocked from being able to use Credits for market purchases in the future.
The purchase and use of Credits is a convenience service that Splinterlands provides to players, and we reserve the right to deny that service to any player for any reason and without notice. Please note that Credits are not required for making purchases or taking any actions in the game, so even if a player is unable to purchase or use Credits, they are still able to purchase items in the shop or cards on the market using the Dark Energy Crystals (DEC) cryptocurrency token which can be acquired on various third-party marketplaces.
Starting with the next ranked play season the new drop_league operation will be removed from the game so players will no longer have the ability to drop down to a lower league leaderboard within the current ranked play season.
This was added in as a temporary measure to deal with issues around the transition to the new collection power and league leaderboard system, but now that a couple of seasons have gone by it should not be needed and only serves to provide more potential avenues for exploits.
As a reminder, if a player's rating and/or collection power drops below the minimum threshold, they will still drop to a lower league for ranked battles and season/quest rewards, however they will remain as part of the higher league's leaderboard for the remainder of the season.
Starting tomorrow - Wednesday, October 7th - only a pre-approved list of accounts will be able to be specified as the "market" parameter for market transactions in order to receive the market fee payment. In the past it has been possible for players to modify the market purchase transactions and add their own account as the "market" so that they would receive the fee.
The ability to specify a market account in the transaction was meant to allow and promote the creation of third party marketplaces, not to allow more tech savvy users to avoid market fees.
Initially, the list of approved market accounts will be peakmonsters, monstermarket, and splintx. If there are any other legitimate third-party Splinterlands marketplaces that would like to be added to the list, please contact 
The hard fork of the Hive blockchain that was originally scheduled for today at 10 AM ET / 14:00 UTC has been delayed. The hard fork will take effect when a supermajority of Hive witnesses start running the updated blockchain code. The exact date and time that the hard fork will take effect is unknown, but looks likely to be later this week.
As we mentioned previously, we will be putting the game into maintenance mode shortly before the hard fork takes place to ensure that everything is working properly before allowing players back in.
Finally, we also have a significant change to the new account creation process for new players which we plan to release tomorrow as well in preparation for a potential influx of new players over the next few weeks, but we will be publishing the details of that in a separate post later today as this post is already getting very long!
