The problem ENS-folio solves

The Problem it Solves

In the Web3 ecosystem, a person’s contributions and reputation are fragmented across multiple platforms.

Developers, DAO contributors, and community members leave their digital footprint in many different places such as:

Wallet transactions on block explorers

NFT collections across marketplaces

GitHub repositories

DAO governance participation

Hackathon projects

POAP badges from events

Because this data is scattered, understanding someone’s Web3 identity requires manually checking many different platforms like Etherscan, GitHub, Snapshot, and NFT marketplaces.

This creates several problems:

❌ Difficult for recruiters or collaborators to evaluate Web3 builders

❌ No unified way to showcase on-chain reputation

❌ Web3 contributors lack a simple portfolio or resume

❌ Identity in Web3 is tied to wallets, but wallets don't present meaningful context

As a result, Web3 still lacks a simple, unified identity layer similar to LinkedIn or a personal portfolio in Web2.

How ENS-folio Solves This

ENS-folio transforms ENS names into decentralized Web3 portfolios.

By simply entering an ENS name, the platform automatically aggregates important on-chain and developer data into a single unified profile page.

Each ENS profile can showcase:

🧾 Wallet address and on-chain activity

🖼 NFT collections

🎟 POAP badges from events and hackathons

🏛 DAO participation and governance activity

💻 Projects and developer contributions

🔗 Social links like GitHub and Twitter

This makes it easy for anyone to instantly understand a person’s Web3 reputation and work.

What People Can Use It For

ENS-folio makes several existing tasks much easier and more transparent:

🧑‍💻 For Developers

Create a Web3-native resume

Showcase hackathons, NFTs, and on-chain activity

Share a single ENS-based portfolio link

🏢 For Companies & DAOs

Quickly evaluate developers and contributors

Verify real on-chain reputation

Discover active Web3 builders

🌐 For the Web3 Community

Build credible decentralized identities

Make Web3 contributions more visible

Create shareable ENS-powered personal pages

Why This Matters

ENS-folio helps bridge the gap between wallet-based identity and real reputation in Web3.

Instead of scattered data across platforms, your ENS name becomes your unified Web3 identity and portfolio.

Challenges we ran into

One of the main challenges we faced was resolving ENS names reliably and linking them to the correct wallet address. ENS resolution requires interacting with Ethereum mainnet, while our smart contract for profile storage was deployed on Base Sepolia. Managing data across multiple networks initially caused inconsistencies in fetching profile and wallet data.

To solve this, we separated the data flow: ENS names are resolved using an Ethereum mainnet RPC provider, while profile data is fetched from our smart contract deployed on Base Sepolia. This clear separation of network responsibilities ensured reliable ENS resolution while still allowing users to store and own their profile data on Base.

Another challenge was aggregating data from multiple APIs such as NFTs, POAP badges, and wallet activity. Each API returned data in different formats, so we had to normalize the responses before displaying them in the UI. By creating a small data processing layer in the frontend, we were able to standardize the data and present it in a clean portfolio interface.
