Building a Web3 Portfolio

Showing relevant work

A portfolio gives an employer examples to examine alongside your resume and interview. Choose work that demonstrates the requirements of the role you want.

For each project, explain your contribution, design choices, tests, and limitations. Distinguish personal experiments from work deployed for real users.

The Ideal Web3 Portfolio

For Developers

1. A Deployed Smart Contract

Deploy at least one smart contract to a testnet (Sepolia, Base Sepolia). Ideas:

A simple ERC-20 token with custom tokenomics
An NFT collection with on-chain metadata
A basic DeFi vault that earns yield
A multisig wallet

Include the contract address, verification link (Etherscan), and a brief write-up of your design decisions.

2. A dApp Frontend

Build a React/Next.js frontend that connects to your smart contract using wagmi or ethers.js:

Wallet connection (MetaMask, WalletConnect)
Contract interaction (read state, send transactions)
Transaction status tracking

Deploy it on Vercel. Having a live URL is critical.

3. Open-Source Contributions

Find Web3 projects on GitHub and contribute:

Fix bugs in developer tooling (Hardhat, Foundry, wagmi)
Improve documentation
Add test coverage
Build integrations or plugins

Start with issues labeled "good first issue" or "help wanted."

4. A Technical Blog Post

Write about something you learned or built:

"How I built a flash loan arbitrage bot on Uniswap V3"
"Understanding MEV: a developer's guide"
"Deploying my first smart contract on Base"

Publish on Mirror.xyz (Web3 native) or your personal blog.

For Non-Developers

1. Community Building

Manage or moderate a Discord server for a Web3 project.
Grow a crypto-focused Twitter/X account with thoughtful analysis.
Organize or speak at Web3 events.

2. Content Creation

Write threads explaining complex Web3 topics in simple terms.
Create educational content (videos, infographics, newsletters).
Translate documentation for non-English communities.

3. Governance Participation

Actively vote on DAO proposals (Snapshot, Tally).
Write governance proposals or analyses.
Participate in forum discussions.

Document all of this with links and screenshots.

4. Research and Analysis

Write token analysis reports.
Create protocol comparison frameworks.
Analyze on-chain data using Dune Analytics dashboards.

Portfolio Presentation

GitHub Profile

Pin your best Web3 repositories.
Write detailed READMEs with screenshots and live demo links.
Use descriptive commit messages showing your thought process.

Personal Website

Your deployed dApp can serve as your portfolio site.
Include a "Projects" section with screenshots, tech stack, and links.
Add an "About" section explaining your Web3 journey.

On-Chain Identity

Use an ENS name (yourname.eth) as your on-chain identity.
Collect POAPs from events and hackathons you attend.
Build a Farcaster or Lens profile to establish social presence.

Hackathons as project practice

Hackathons offer deadlines, collaborators, and feedback. Their value depends on the project and your participation:

You build something real in 48 hours with a team.
Winning or placing gets you noticed by VCs and hiring managers.
Many hackathon projects become funded startups.
The relationships you build at hackathons often lead directly to job offers.

Key Takeaways

Ship working, deployed projects - not mockups.
Open-source contributions are the strongest signal for developers.
Non-developers should document community, content, and governance work.
Document what you built at a hackathon, including work left unfinished.
Public work can support a resume; it does not replace an accurate employment history.
