We recruit based on client-project needs so can offer blockchain specialists and development services that incorporate any required tech stack.  However, some of the programming languages, frameworks and tools we have worked with most on blockchain development projects are: Programming languages Solidity: The programming language most commonly used to create smart contracts on the Ethereum blockchain. It’s similar to JavaScript and is specifically designed for developing blockchain applications. Go: Google-developed Go, often mistakenly referred to as Golang, is used in Ethereum and Hyperledger Fabric. Rust: A high-performance language used in several blockchain projects including Parity and Polkadot due to its safety and speed. JavaScript: JavaScript is frequently used to interact with Ethereum and other blockchains through libraries like web3.js and ethers.js, Python: Popular for its simplicity, Python has several libraries for interacting with blockchain networks. Tools and frameworks Truffle Suite: A development environment, testing framework, and asset pipeline for blockchains using the Ethereum Virtual Machine (EVM). Ganache: Part of the Truffle Suite, Ganache is used to create private Ethereum blockchains for testing and experimentation. Hardhat: A development environment for compiling, deploying, testing, and debugging Ethereum software. MetaMask: A browser-based wallet used to interact with Ethereum’s blockchain and decentralized applications (dApps). Remix: An online Solidity IDE that allows you to write, deploy, and test smart contracts.
