FAQs

When reviewing a freelancer's portfolio, focus on their experience with Ethereum blockchain projects, their proficiency with JavaScript and specifically Web3.js, and any past work on decentralized applications (dApps). Look for examples of smart contract development, token-based systems, or decentralized finance (DeFi) applications to assess their technical skills and project outcomes.
To ensure clarity, break down the project's deliverables into clear, specific tasks such as developing smart contracts, integrating wallet features, building user interfaces for dApps, or implementing blockchain-based voting systems. Outline any specific technologies or tools the freelancer should use, and decide on milestones that align with major phases of the project to help track progress effectively.
To onboard a Web3.js expert, start by providing them with comprehensive project documentation, including objectives, timelines, and technical requirements. Share access to any necessary resources such as development environments or testing platforms. Utilize Contra's onboarding tools to clearly communicate expectations and establish lines of communication, ensuring the freelancer has everything needed to begin their work efficiently.
