Blockchain Development - Internship

As a Blockchain Developer Intern, you will work on architecting and developing
modular, scalable decentralized systems from smart contracts to full-fledged
dApps.

You'll collaborate on MCPs (Modular Chain Protocol Systems) and Web3
applications that push the boundaries of blockchain scalability,
composability, and real-world usability.

This internship offers hands-on exposure to production-grade blockchain
engineering from writing secure, gas-efficient smart contracts to integrating
multi-chain SDKs and developing complex dApp workflows.

Selected intern's day-to-day responsibilities include:

1. Design, develop, and audit smart contracts using Solidity (EVM) or Rust
(non-EVM) with an emphasis on security and gas efficiency.
2. Build, test, and deploy dApps on multiple blockchains using frameworks
like Hardhat, Foundry, or Scaffold-ETH.
3. Work on Modular Chain Protocol Systems (MCPs) integrating core components
such as sequencers, verifiers, bridges, and settlement layers.
4. Implement wallet-based authentication (MetaMask, WalletConnect, SafeAuth)
and manage user sessions securely.
5. Integrate on-chain and off-chain data using oracles (Chainlink, RedStone)
and indexing tools (The Graph, SubQuery).
6. Collaborate on cross-chain interoperability using LayerZero, Axelar, or
Wormhole SDKs.

Apply security-first practices, including:
1. Access control & signature verification
2. Reentrancy protection & SafeMath usage
3. Rate limiting and on-chain validation
4. Write clean documentation for contracts, SDKs, and protocol modules.
Collaborate with backend and frontend teams to deliver complete Web3 product
experiences.

Skills Required
1. Languages: Solidity / Rust / TypeScript
2. Frameworks: Hardhat / Foundry / Truffle / Remix
3. Web3 Libraries: Ethers.js / Web3.js
4. Blockchain Fundamentals: Gas model, transactions, consensus, storage
5. Smart Contract Standards: ERC-20, ERC-721, ERC-1155
6. Version Control: Git, GitHub, CI/CD for contracts
7. Cross-Chain & L2 Solutions: Arbitrum, Optimism, Polygon, zkSync
Oracles & Indexers: Chainlink, The Graph

Bonus: Experience with rollup SDKs, validator systems, or modular chains

Who Can Apply
1. Freshers or undergrads with a strong interest in blockchain systems, Web3
infrastructure, and decentralized app development.
2. Prior experience building smart contracts or dApps (personal, academic, or
hackathon projects).
3. Basic familiarity with testnets, wallets, or blockchain SDKs will be an
added advantage.

Perks
1. Work on real-world blockchain and MCP projects with a focus on
scalability, composability, and decentralization.
2. Receive hands-on mentorship in smart contract engineering, protocol
design, and blockchain security.
3. Certificate of Internship + Letter of Recommendation (based on
performance).
PPO opportunity for top-performing interns.
