Tools and first-week setup
The tools a Blockchain & Smart Contracts intern uses and how to set up your workspace in week one.
These are the main tools for Blockchain & Smart Contracts tasks. You do not need all of them on day one; the Level 1 tasks tell you when to install each one.
- Solidity
- Remix IDE
- Hardhat / Foundry
- OpenZeppelin
- ethers.js / viem
- Test-network wallet
- IPFS
Set up your workspace
- Create a free GitHub account if you do not have one, with a professional username, and set up your LinkedIn profile: every task is submitted with a LinkedIn post.
- Create one repository for the internship, for example blockchain-and-smart-contracts-solidity-internship, with a README that says who you are and what the repo holds.
- Keep one folder per task, named with the task number and title, so mentors find your work quickly.
- Commit small changes every day with clear messages. Your daily work report uses these commits as proof.
- Never commit passwords, API keys or personal data. Put secrets in a .env file and add it to .gitignore.
Your first tasks
| Task | What to do |
|---|---|
| Blockchain basics | In a repo named web3-internship, explain blocks, hashes, consensus, wallets, gas and public versus private chains with simple diagrams. |
| Hashing in code | Write a small Python or JavaScript program that chains blocks with SHA-256 hashes and shows how changing one block breaks the chain. |
| Wallet on a test network | Set up a browser wallet on a test network (for example Sepolia), get free test coins from a faucet and send a test transaction. Never use real money. |
| Block explorer | Look up your test transaction on a block explorer and explain every field. |
