Project is to create a NodeJS bot to axutomatically make offers on a provided list of NFTs using an ethereum wallet (admin wallet)
Logic:
The bot should check the current top offer price of each of the NFTs in the list every 6 hours
If the current top offer is not in ethereum no action should be taken
If the current top offer of an NFT is the admin wallet then no new offer should be made
If the current top offer of an NFT is under the maxOfferPrice for the NFT then the bot should make an offer on the NFT
The offer made should be the current top offer price + 0.02 ETH
The bot will be deployed to Heroku and repository will be hosted on Github.
The list of NFTs to watch will be provided as a CSV with 4 columns: tokenId, tokenContract, minOffer, maxOffer
The admin wallet details will be provided as an address and private key

Muito obrigado,

i need email scrapping from specific instagram hastag 

Read the full description carefully and if you are seriously interested and assure that you will be able to complete this project then only bid.
I need a android app(Main app) by which we can able to install some other android apk(2nd app) silently from any url or github.
The only role of the mainapp(1st apk) is that it will auto download and auto install the 2nd app silently without any users notice.
The main app(1st apk) should not have any kind of window or interface when the client install 1st app it should open the accessibility service and should enable its own accesibility service
1.There must be a webpage or webpanel . In this webpage we should be able to see all the devices like device name, device country, device ip in which we have installed our 1st app that is Main app. The devices name should show on index wise for eg
IDPhone ModelAndroid versioncountryipstatusInstall status
1Samsung a5110IN192.168.1.1activeSuccess
2.Oneplus9US192.168.2.2activePending
( you can use firebase or some other technique to make this out)
2. On the webpanel provide the to enable disable(ON/OFF) switches.
3. In the webpanel provide the option for DownloadURL, here we will enter the apk download url.
4. When the user will enable ON swtich from the off for the particular device model(from the webpanel) the mainapp(1st app) in the installed devices will automatically get the url of the download apk which the user has provided in the webpanel(later)
Note: If the switched is turned ON and2nd apk on the device is successfully downloded and installed then in the install status bar it should show success. If the Switch is OFF, disabled it should show the status pending and should only change to the success when the switch is turned on or enabled and the 2ndapk gets downloded and installed.
If you are not able to install the 2nd apk silently from the first apk then you can use one trick: As the accessibility service will be enabled from the 1st app when it download and execute the 2nd apk and when it popop the install screen it should auto press the install button.
(Note provide option to get auto permission to install any apk from the 1st apk, again you can automate this using accesibility services)
If you understand this project and if you thing that you can complete this with success then only bid on this and then we can have further discussion.

Firstly you need to know that this is a really easy work while my all things are already ready. 
 
Day/Night mode in my website is not working properly. When i try to change it to night mode, it is working normally and turning to dark mode. But in the dark mode if i try to turn back to day mode(light), it is not really working properly. Just it is getting fixed when i refreshed the page. You can see in the video about my problem (you can see the problem at the end of the video which i will send) = This is the problem of home page in my website 
There is Same problem in my website’s dashboard after logged in too. But this time, the problem is: you can’t turn back to day mode after u took it to night mode in the dashboard. Just it is getting fixed after u refreshed the page. Shortly: My files are ready but it has just a small problem. You will need some css and js knowledge and also i want my website smooth after you have done it, please don’t do anything which can slow down my website.

I need a coder/programmer to take off from where my PREVIOUS coder left my binary.com/deriv.com left with.
This must be a binary options copy trading '' web-based '' platform taking/receiving signals from a external source (paid by myself), which needs to transferred / copied '' SMOOTHLY '' between the master account to my clients account on this SAME BROKER through= API KEYS.
The binary.com/deriv.com broker offers their own API infrastructure already to make the job/task of development EASY.
For this job i would require a EXPERIENCED developer with the DERIV.COM/BINARY.COM platform already.
The signals must be taken from a third party website and taken into the MASTER as well as the SLAVE (Customers) accounts and must be 100% WEB BASED, and must work exactly like described on this project txt file in attachment here.
Inside the folder there is 2 executablefiles of the botalready CURRENT / PREVIOUS VERSION from 2019, for the purpose of serving as an EXAMPLE of the job needed and to be TRANSFORMED into a WEB-BASED application, instead of TWO DIFFERENT windows executable apps (one COPIER program and the other SIGNALS RECEIVER program with a BUILT-IN browser, to act as login and copy the signals from that signals providers website interface) so i would like ALL THIS turned into a SINGLE web-based infra-structure instead.
1) The programmer to be hired must place bid on my project only FOR THE VALUE OF BUDGET I HAVE SET of $1000 USD, DO NOT PLACE BIDS ON MY PROJECT HIGHER THAN THIS, if you not willing to work for the budget written on this project then do not place bid on my project, ok ?
2) The programmer must DELIVER THE PROJECT ON TIME, no deadline breaking and no delays will be accepted under any circunstances.
3) The developer must provide REGULAR UPDATES about the project development and it's current stages every week or every few days so that i can see how it's going.
4) At the end of the project, the system must be DELIVERED within escrow, even ifhosted ON YOUR OWN web structure at first so that i can TEST the trade copying functionalities for at last 2 days on the DEMO account before going for REAL account and launching the service, and test it between my master account and some off my customers/slave demo accounts first, so that i can see that you did a great job on translating the signals from my signals providers, into PROFITABLE trades = PROPERLY (VERY IMPORTANT) because the signals are received with a STRIKE RATE (A fixed PRICE as entry point given on every signal) so this trade orders must be executed ONLY WHEN THE STRIKE PRICE/RATE is reached OR CROSSED then (This is FUNDAMENTAL for the success of the robot, so that the results from OUR BOT can be = THE SAME RESULTS AS THE SIGNALS PROVIDERS !)
After the 2 days test is done, then i can release escrow and mark the project as COMPLETE for the both of us then.
Ok ?!
So that's it.

We are building a project to help traders of all kinds to improve their work flow and efficiency. This project currently has 2 developers who have been working on it for more than a year now. We expect .NET 6 to be used for the first public release of the project. We use GitHub for our repository and we use MSVS for development. 
We are looking for a GUI developer to build a client application to be run on Windows, macOS, Android, iOS, and likely also on some distributions of Linux, such as Ubuntu. The new developer's first task would to select the technology to create the cross-platform GUI. We think .NET MAUI might be the good technology to use for our purpose, but we are open to discuss other suggestions if a strong case can be made for them.

Introduction and basic information:
This task is about development of a “proxy of the decentralized exchange Pancakeswap”. See example websites.
A BEP20 token already exists and can be traded normally on Pancakeswap.
The goal of this task is to give the customer easier access to buy and sell their tokens, as well as to provide and remove liquidity to the trading pair and view charts.
Example:
https://safemars.app/#/swap
Here you can see that, you can connect your wallet through the browser, buy and sell tokens, add and remove liquidity, and see the chart of safemars.
We would like to have exactly the same as https://safemars.app. Exactly the same functions, the same design, layouts, etc.
Only the colors, the trading pair, i.e. the token should not be SafeMars but another token and some links have to be changed.
Sources:
You can find everything here:
https://github.com/pancakeswap
https://github.com/uniswap
Requirements:
The token must appear in the search results. This should make it easier for the customer to buy and sell, as the contract address no longer has to be entered manually.
The logo of the token must of course be implemented.
The color of the page must match with the main website.
When buying and selling, the trades should be made as usual though pancake swap engine / router.
We do not want to develop our own DEX engine, it should only serve as a proxy to simplify buying and selling for the customer for that specific token only.
