Core Devs has been a great team to work with. During the development process of our tool we ran into a few issues that couldn't be foreseen. Shuvo and his team almost doubled the amount of working hours WITHOUT charging us for that. Great service where you can feel that the developers behind are doing their best to satisfy you. Nice experience! We'll be back. Thank you.

Contract was finished faster and easier than expected! Core Devs did an amazing job at helping me build the most profitable project of my life. Even thought they were hit with CoVid and were delayed 2 weeks, they still finished a few weeks ago and they just noticed that the contract was still open. Overall, very impressed with their lead developer who helped me understand all the amazing ways to make this bot work wonders! Thank you CoreDevs!

It has been a really great journey to work on the project with Mahbub and his team at Core Devs. I started the project with some uncertainty and confusion about how NFT smart contacts will work an in the end, I've learned so much from the team, and they are super patient about explaining to me lots of detail. The overall process is super smooth and the final deliverable is beyond expectation.", reviewFrom: 'Upwork verified Review

Frequently Asked Questions
Core Devs Ltd is a blockchain and automation development company that builds custom software across web2 and web3. These are the questions we hear most often from founders, trading teams and businesses planning their next product.
What does Core Devs Ltd do?
We design and build custom software: smart contracts, dApps and token staking platforms, crypto wallets, trading bots, SaaS products, web and mobile applications, CRM and company management systems, and the automation that ties them together. Our team works with both web2 and web3 technologies, so one team can deliver the whole product.
What kinds of trading bots do you build?
Our trading work includes a cross-DEX arbitrage bot that uses flash loans to capture price spreads between Uniswap and Sushiswap, a Solana sniper bot for new token listings, a Binance Futures bot with a live news feed, a copy trading platform that mirrors orders across accounts, a mempool-scanning desktop bot and Telegram trading bots with limit orders and DCA.
Which industries have you worked in?
Crypto trading and DeFi make up a large part of our work, alongside NFT collections and Web3 marketplaces. We have also built software for e-commerce and dropshipping, insurance agencies, ambulance services, self-storage rate analysis, social media marketing and agile project management. Each project is documented in our case studies.
Which blockchains and technologies do you use?
We write smart contracts in Solidity and build dApps with Web3.js on Ethereum, BSC, Solana and TRON. For web applications we mostly use Node.js, Express, React and MongoDB, mobile apps are built with React Native, and our automation tools rely on Puppeteer, Selenium and Python.
Can you automate tasks outside of crypto?
Yes. We have built an Instagram automation tool that monitors influencers and handles engagement, a LinkedIn bot that interacts at a natural pace, a SaaS platform that automates listing and sharing for Poshmark sellers, and a scraper that tracks storage rental rates across more than 10,000 US locations.
Do you build NFT projects?
Yes. We built The Floaters, an 88-piece NFT collection with an ERC721A contract, IPFS metadata and a React minting dApp, and Evil Token, an NFT marketplace with ERC20 payments and staking. Let's Go Rare adds escrow and dispute resolution for NFTs and physical goods, and our NFT trading web app automates buying and selling on OpenSea.
Do you develop SaaS and business software?
Yes. Our SaaS work includes Poshmark Automation for online sellers and Scrumo, an agile project management app with sprint tracking, reporting and built-in meetings. We also build internal systems such as a task tracker for insurance agencies, CRM platforms and company management software shaped around your workflow.
Do you build mobile apps?
Yes. We build native and cross-platform apps for Android and iOS using JavaScript and React Native. A mobile app can be delivered on its own or alongside the web platform, smart contracts or backend it connects to, all by the same team.
Can you work on an existing product?
Yes. Besides building new products from scratch, we update existing systems: adding features, integrating third-party tools or extending a platform you already run. Share what you have and what you want to change, and we will suggest the best way forward.
Where is Core Devs located?
Our headquarters is in Mirpur DOHS, Dhaka, Bangladesh, and we have offices in Covent Garden, London and Dubai Marina, Dubai. We work with clients around the world and can meet online wherever you are.
Why work with Core Devs?
You get one team that understands both traditional software and blockchain, with delivered projects in trading, Web3, automation and business software that you can review before you decide. We make every effort to be open and honest with our clients and partners, because we believe trust is an essential part of any business relationship.
