Crypto: Initial ArbitrageManager implementation
In this post, we will start with some preliminary analysis of the blocks/trnsactions content and progressively build our way to an Arbitrage management system for EVM blockchains 😎 Or well… an initial version of it at least lol.
Crypto: Collecting tokens and pairs from DEX
So lately, I've been working on restoring more of my blockchain management system (with the ultimate goal to get back to some arbitrage experiments 😎), and right now, I have a first version of a “Binance Smart Chain” blockchain, “ERC20” compatible Token and Pair classes, and “PancakeSwap” DEX based on a unified “UniswapBase” exchange representation.
And from the PanscakeSwap DEX (ie. Decentralized exchange) object I can request to collect all the pairs available on the exchange and all the tokens used in those pairs, to store information about them in a database. It's working pretty well already, but I still have a few exceptions from time to time due to very specific errors, and I'm still in the process of collecting the pairs only for PancakeSwap (version 1 I mean 😅): there are about 133K pairs already there!
What I will do here is to provide some improvements/extensions around this concept to try to improve it further, so let's get to work!
Crypto: Computing EVM blockchain gas price statistics
Continuing from my prevvous article on the Linear Finance reward claims, I think I need to push it a bit further on the gas price I use for my transactions: using an hardcoded value of 7Gwei is certainly not ideal, instead I should build a dedicated system to continuously update the statistics on the gas price, so let's implement that system here.
Crypto: Restoring automatic Linear Finance claims
Long story short: in the past year or so I have been implementing many python scripts/objects to handle interactions with some blockchain protocols automatically. And now that I have started to clean things up with the NervProj framework it's time for me to get back to these, and restore most of those scripts.
One good starting point I believe is the automatic claim system I built for Linear Finance on the Binance Smart Chain: This will force me to cover quite a lot of points already so this may take some time, but hey, we have to start somewhere right ?
Solana study case: Withdrawing LPs from SunnyAG protocol
Okay guys, so, that's not quite what I wanted to handle next, but I currently have a bit of a problem with the Sunny Aggregator platform: I have some funds on the pools there, which I would like to withdraw, but due to a nastly issue with incorrect handling of the “point” in the values that you will enter on the website, you basically cannot withdraw any value with decimals: for instance you can withdraw “7” LPs from a given pool, but not “7.” or “7.0”, or “7.78”, etc.
And I guess the dev team is going its best, but that still a bit too slow from my perspective. And on top of that, I've been waiting to jump into solana programming since a long time now, so that sounds like a good opportunity to give it a try here 😊!
NervProj: Finding & adding monitored coins
In one of my previous articles (available here) I introduced support to list/add/remove monitored coins from the command line with my coingecko component. This is very nice and all, but this also assumes that you know what is the ID of the coin you want to add to the list, which is not always absolutely clear…
So, what I want to do here is to add support to search for all coins matching a given pattern and list them directly on the command line so I could then select the proper one in the list and add the corresponding coin id.
Cryptoview: Restoring the charts panel
So, continuing the work started in my previous article on this topic, I'm now going to restore the “chart panel”, which was used to display 4 charts of the selected coin with 4 different time frames. As in the initial version I will use matplotlib to draw the chart. And in fact, I've already been trying to integrate that package with pyqt5 and it works just fine, so this task here should not be too hard hopefully 
. Let's get started!
Cryptoview: Restoring coins overview
Okay, so, I desperately need to restore my cryptoview project now. This was formerly based on wxPython and I would really like to translate this into pyqt5 in the process. I just hope this wont take me too long…
