SigmaVault

Sigma Vault is a comprehensive DeFi vault management platform built specifically for the ETHGlobal hackathon using Euler Protocol's infrastructure. This project addresses the critical need for user-friendly interfaces in complex DeFi ecosystems by creating an intuitive dashboard that simplifies interaction with Euler's lending pools and vault strategies.

Through our platform, users can maximize their earnings without the hassle of manually managing their positions. Our powerful indexer continuously monitors pool states, and when conditions change, we automatically trigger on-chain transactions to rebalance or hedge positions on behalf of users.

Key innovations include real-time integration with Euler's pool data via GraphQL, dynamic vault detail pages that showcase live performance metrics, and a responsive design that makes DeFi accessible on any device. The application fetches live token balances, validates transactions in real-time, and provides visual feedback throughout the user journey.

The project demonstrates how modern web technologies can be leveraged to create compelling user experiences in DeFi, specifically showcasing Euler Protocol's capabilities for multi-asset vault management, yield optimization, and risk assessment in an accessible format.

Our indexer is currently indexing

This project is built using cutting-edge web3 technologies centered around Next.js 15 with the App Router for optimal performance and developer experience. The blockchain integration utilizes wagmi and viem for type-safe Ethereum interactions, while RainbowKit provides seamless wallet connectivity across multiple providers.

Core Architecture:

Backend: Indexer SQD - indexing euler factiry, euler hooks and our WIP contract deposits/withdrawals Telegram bot that push real time messages triggered by event ( @sigmavaulteuler ) Frontend: Next.js 15 with TypeScript for full type safety Styling: Tailwind CSS v4 with custom gradients and glass-morphism effects Blockchain: wagmi + viem for contract interactions with our WIP smart contract. Data Fetching: tRPC for type-safe API calls to fetch Euler pool data from our indexer. State Management: React hooks with real-time contract data synchronization

Notable Technical Implementations:

Smart Contract Interaction: Automated token approval handling and transaction simulation before execution Dynamic Route Validation: Zod schemas validate vault IDs with proper error handling Type Safety: Full TypeScript integration with inferred types from tRPC routers Hacky but Notable Solutions:

Used server-only imports to ensure blockchain data fetching happens on the server for better SEO and performance Created a withdraw-only interface that displays deposited amounts as readonly fields while maintaining the same component structure Built a conditional rendering system for vault assets that only shows when users have deposits, eliminating duplicate information display The project showcases how modern React patterns can create intuitive DeFi interfaces while maintaining the security and decentralization principles that make Euler Protocol powerful.
