Dear Delegates,
As the Kromatika developers are greasing their elbows and getting the work done to deliver various aspects of this grant, we have a few suggestions that we believe will benefit the larger Optimism community.
We would like to share these here and we invite your feedback/suggestions.
1/ Liquidity Mining Program
We saw Uniswap use liquidity protocols such as DefiEdge, 0xPlasma, Gamma, Arrakis etc and we think this is the best way to use provide optimized liquidity mining incentives to the Optimism community as opposed to our first thought of doing it in-house.
Our first two choices for liquidity mining distribution are DefiEdge and 0xPlasma. They provide a very efficient and optimized service and we cannot better that service if we decide to do it in-house simply because Kromatika specializes in providing innovative DEX services and not liquidity mining per se.
These liquidity mining protocols have a good track record and we feel it is wise to utilize their expertise because they specialize in it.
The result → More new users will be attracted to actively engage on the Optimism network.
We have been in talks and ready to deploy once we get your stamp of approval.
2/ Gas Refund
So the initial idea was to maintain an $OP gas tank (smart contract that will refund for gas money). From there, the $OP will be transferred to the ones who pay for the txn (biconomy validators).
This means there are two separate gas tanks - one that holds $OP and the other which is the Biconomy gas tank (which will hold $ETH). Kromatika would initially fund the biconomy tank with ETH, and then transfer OP to the validator as they begin to cover gas charges.
After that initial funding by Kromatika in ETH, then the validators will have to top up the Biconomy gas tank with ETH as and when they receive OP from Kromatika.
As we worked out this model, it feels inefficient and lengthy in terms of time and resources spent because OP is not the gas payment token for Optimism network (unfortunately).
Here is a suggestion:
Usage of Kromatika’s limit orders aka FELO(fees earning limit orders). These limit orders are actually concentrated liquidity positions on Uniswap V3 pool at the desired tick range.
Using FELO for OP/ETH, we add liquidity to the pool in exchange for ETH. This ETH can then directly fund the biconomy gas tanks which the validators can then use to cover the users tx costs on swap.
We feel this will be an efficient means of delivering the gas refunds. There is no direct selling, since using FELO (Kromatika’s flagship limit orders) means $OP liquidity is being added to the Uniswap v3 pool at a specific tick range. This can be carried out on a periodic basis based on the delegates recommendation.
We would like to hear feedback on this topic please. 
We are also open to hosting an AMA with the delegates to answer any questions on how this will benefit the Optimism community.
We are open to hear your recommendations and very eager to push the products out asap.
