Blockchain Engineering Intern (Ethereum / Web3 Infrastructure)

Company: World Trade Factory (SKXYWTF)

Location: Remote / India

Type: This is an UNPAID Internship

About the Role

World Trade Factory is building next-generation digital infrastructure at the intersection of blockchain, AI, and global markets. We are looking for a Blockchain Engineer to help design, build, and test smart-contract-based systems and supporting infrastructure in an educational, research-driven, and production-oriented environment.

This role focuses on engineering, security, and architecture — not hype or speculation.

What You’ll Work On

- Design and develop smart contracts on Ethereum and EVM-compatible chains
- Implement and test ERC standards (ERC-20, ERC-721, ERC-1155 as needed)
- Build token utility and staking logic (testnet-first, security-focused)
- Integrate smart contracts with off-chain systems (APIs, indexers, dashboards)
- Write automated tests and conduct basic security reviews
- Support on-chain analytics, event indexing, and data pipelines
- Document contract behavior, assumptions, and upgrade paths

Required Skills & Experience
- Solid proficiency in Solidity and EVM fundamentals
- Solid understanding of Ethereum architecture, gas mechanics, and transactions
- Experience with smart contract testing frameworks (Hardhat, Foundry, or Truffle)




- Familiarity with web3 libraries (ethers.js, web3.js)
- Knowledge of common smart contract vulnerabilities (reentrancy, overflow, access control)
- Comfortable working with Git and code reviews

Nice to Have
- Experience with Layer 2s (Arbitrum, Optimism, Base, Polygon)
- Familiarity with tokenomics modeling (emissions, incentives, staking design)
- Exposure to on-chain analytics (The Graph, Dune, custom indexers)
- Backend experience (Node.js, Python)
- Prior security auditing or formal verification exposure

What We Care About
- Engineering discipline over hype
- Clear documentation and reproducibility
- Security-first mindset
- Ability to reason about incentives and edge cases
- Comfort working in early-stage, research-heavy environments

For Students / Interns (OPT / CPT Eligible)
- Project-based, academically aligned work
- Testnet and simulation-focused development
- No fundraising, token sales, or solicitation activities
- Responsibilities aligned with computer science, engineering, or blockchain coursework

What We Offer
- Work on real blockchain infrastructure — not demos
- Mentorship and exposure to AI + macro research systems
- Flexible work structure (remote-friendly)
- Opportunity to grow into long-term or paid roles as we scale
