How to Write Case Studies for Web3 Frontend Projects

Why case studies beat project cards

A project card with a screenshot and tech stack tells a visitor what you built. A case study tells them how you think, how you solve problems, and what impact you deliver. Clients hire based on case studies, not project lists.

For Web3 frontend work specifically, case studies prove you understand wallet integration, on-chain data challenges, and the UX expectations of crypto users.

Recommended structure

Every case study follows five sections: Problem, Role, Stack, Solution, and Impact.

Problem

Describe the business context. Who was the client? What were they building? What was broken or missing?

Example: "A DeFi protocol launching on Base needed a portfolio dashboard showing user positions across 4 lending markets. Their existing MVP took 8 seconds to load and lost 60% of users at the wallet connection step."

Role

Be specific about what you owned. "Frontend developer" is too vague. "Led frontend architecture, wallet integration, and dashboard UI for a team of 3" is compelling.

Stack

List technologies with brief justification for key choices:

"Next.js 14 App Router for SSR of public protocol data. wagmi v2 + viem for wallet interactions. TanStack Query for on-chain data caching. Recharts for TVL visualization. Deployed on Vercel with edge-cached API routes."

Solution

This is the core of the case study. Describe 2–3 key technical decisions and show screenshots.

**Decision 1: Hybrid RSC + client architecture** "Public protocol metrics (TVL, top tokens) render server-side for instant first paint. Wallet-specific portfolio data loads client-side after connection. This cut initial load from 8s to 1.4s."

**Decision 2: Multicall batching** "Replaced 40 individual balanceOf RPC calls with a single multicall3 request. Reduced RPC usage by 95% and portfolio load time from 6s to 800ms."

**Decision 3: Progressive wallet connection** "Moved wallet connection from a blocking gate to an inline prompt within the portfolio panel. Users can browse public data first. Connection conversion increased 3x."

Impact

Quantify outcomes wherever possible:

- "Portfolio load time: 8s → 1.4s" - "Wallet connection conversion: 12% → 36%" - "Shipped MVP in 4 weeks" - "Dashboard handles 15K daily active users" - "Zero RPC rate limit issues in production"

Describing dashboard, wallet, and data work

For dashboard work: show before/after screenshots. Describe the data architecture (how many sources, caching strategy, update frequency). Mention specific challenges like multi-chain support or real-time price feeds.

For wallet integration: describe which wallets you support, how you handle network switching, and what error states you built. Clients want to know you have handled production wallet edge cases.

For data-heavy features: explain your indexing approach (The Graph, custom API, direct RPC). Describe how you handle loading 10K+ rows. Mention caching and performance optimizations.

Showing technical decision-making

Clients and hiring managers want to see your reasoning process. For each major decision, explain what alternatives you considered and why you chose your approach.

"We evaluated Moralis for wallet history but chose The Graph because we needed custom event filtering across 3 protocols. Moralis would have worked for an MVP but would not scale to our aggregation requirements."

Screenshots to include

Dashboard overview (the hero shot). Wallet connection flow. Mobile responsive view. A data table or chart close-up. Before/after performance comparison if applicable. Error state handling (shows production maturity).

Writing without exposing confidential details

Use anonymized descriptions: "A Series A DeFi protocol" instead of the company name. Focus on technical challenges and your approach, not proprietary business logic. Get client permission before publishing. Offer to let clients review before going live.

FAQ

**How long should a case study be?** 800–1,500 words. Long enough to show depth, short enough to read in 5 minutes.

**Can I write case studies for personal projects?** Yes. Frame them as self-directed challenges with the same Problem/Solution/Impact structure.

**Should I include code snippets?** 1–2 short snippets showing a key architectural decision. Link to a GitHub repo if the code is public.

**How many case studies do I need?** 3 strong ones to start. Add one after each significant project.
