Yoginth S. is a software developer, entrepreneur, and open-source contributor known for his creations in the Web3 ecosystem. He is the founder of the hackathon platform Devfolio, which was acquired by Polygon, and the founder of eth.limo, a public gateway for the decentralized web. He is also a core contributor to the Ethereum Name Service (ENS) and the creator of the decentralized social media application Hey.xyz. ^{[1] [2]}​

Education

Yoginth S. attended the Vellore Institute of Technology (VIT) from 2015 to 2019, where he earned a Bachelor of Technology (B.Tech) in Computer Science. During his time as a student, he gained early industry and open-source experience. He worked as a Software Engineer Intern at the Indian food delivery company Swiggy from January to March 2018. Later that year, from May to August 2018, he participated in the Google Summer of Code as a student developer, contributing to the Oppia Foundation, an open-source project focused on creating interactive educational activities. ^[1]​

Career

Yoginth's career is marked by a series of entrepreneurial ventures and key contributions to foundational Web3 protocols. He began his entrepreneurial journey while still in university and has since been involved in founding multiple companies and projects focused on developer communities and decentralized infrastructure. ^{[1] [4]}​

Devfolio and SuperTokens

In September 2018, Yoginth founded Devfolio, a platform designed to host and manage hackathons for the developer community. As Founder and CEO, he grew the platform into one of the largest communities for builders, particularly in India. Devfolio organized hackathons for major Web3 protocols, including the Ethereum Foundation, Polygon, Solana, and Tezos. The platform's success culminated in its acquisition by Polygon in December 2021, a move intended to help grow Polygon's developer ecosystem. ^[1]​

During the same period, from July 2019 to September 2020, Yoginth also co-founded SuperTokens. This open-source project provides a self-hostable user authentication solution, offering developers an alternative to proprietary services like Auth0 and Firebase Auth, giving them greater control over user session management. ^[1]​

Ethereum Name Service (ENS) and eth.limo

Following the acquisition of Devfolio, Yoginth deepened his focus on the Ethereum Name Service (ENS). Since January 2022, he has served as a core contributor and contractor for ENS. His most significant contribution is as a core maintainer of ensjs, the primary JavaScript library that allows developers to integrate ENS functionalities into their applications. He also developed ethers-ccip-read-provider, a library that enables support for EIP-3668 (CCIP-Read), allowing smart contracts to retrieve data from off-chain sources. This work is crucial for scaling ENS and enhancing its capabilities. ^[1] His blog also details design patterns for ENS off-chain data resolution. ^[4]​

In January 2022, Yoginth founded eth.limo, a public good gateway designed to improve access to the decentralized web. The service acts as a bridge between the traditional web's Domain Name System (DNS) and the decentralized web, allowing users to access websites hosted on the InterPlanetary File System (IPFS) through ENS domains (e.g., accessing vitalik.eth.limo in a standard browser). The project emphasizes privacy by not injecting analytics, ads, or other user-tracking mechanisms. ^[1]​

His current professional title is Engineer at ENS Domains, the organization that stewards the ENS protocol. ^[3]​

Aave and Lens Protocol

Prior to his current focus at ENS, Yoginth worked at Aave Companies as a Senior Software Engineer from November 2021. In this role, he focused on building the backend infrastructure for the Lens Protocol, a decentralized social graph. On February 9, 2023, he was involved in promoting the testnet launch of GHO, Aave's native decentralized stablecoin. His work at Aave highlights his experience with both decentralized finance (DeFi) and decentralized social media infrastructure. ^{[4] [3]}​

Major Projects and Contributions

Yoginth has founded and contributed to several influential open-source projects, primarily using the Go and TypeScript programming languages. His work often sits at the intersection of social media and cryptocurrency. He has stated that his focus is on building products that "feel personal, contextual, and a little bit magical," and has expressed an affinity for the "slow internet," which values more deliberate online interactions. ^[5]

Hey.xyz

Yoginth is the founder of Hey.xyz, a decentralized and permissionless social media application built on the Lens Protocol. The project, primarily written in TypeScript, gained significant popularity within the open-source community, with its main GitHub repository (bigint/hey) accumulating over 29,500 stars and 1,800 forks. ^[2]

To support the application, Yoginth developed several tools and wrote about the technical challenges involved. In an April 2025 blog post, he detailed the implementation of the Open Graph protocol for Hey.xyz to ensure that links shared on platforms like Twitter and Discord would generate rich media previews. This work led to the creation of metadata, an open-source microservice written in Go that provides Open Graph, oEmbed, and Twitter Card data. ^[4]

Hey Token Deployment Incident

On November 1, 2025, Yoginth published a detailed Root Cause Analysis (RCA) after accidentally deploying "Hey" tokens on an internal environment named "Clanker." The public disclosure provided a transparent account of the operational mistake, the factors that led to it, and the lessons learned. This incident highlighted his commitment to transparency and responsible development practices within the DevOps and smart contract deployment lifecycle. ^{[5] [4]}

Open Source Software

Under his GitHub alias bigint, Yoginth has created and contributed to numerous open-source projects. He is a member of the GitHub Developer Program and holds multiple achievements for his high level of activity, including "Pull Shark" and "Starstruck." ^[2]

His notable project and library creations include:

• Roundhouse: A webhook-based Discord command bridge written in Go. Announced in September 2025, it is designed to simplify bot management by routing commands from a single entry point to multiple bots within a server. ^[4]
• work-queue: A lightweight, persistent, and embedded work queue library designed for Go applications. ^[4]
• eth-hd-wallet: A simple, lightweight, and BIP32-compliant Hierarchical Deterministic (HD) wallet for Ethereum.
• lit-share-modal-v2: A component for interacting with the Lit Protocol, a network for decentralized access control.

In addition to his own projects, Yoginth is an active contributor to other foundational Web3 tools, including the wagmi library of React Hooks for Ethereum and the RainbowKit library for adding wallet connections to dApps. His GitHub profile shows he is a member of several relevant organizations, including @ensdomains, @cultivator-dao, and @jekyll. ^{[1] [2]}
