plexi

Plexi is a composable ERC-4626 vault on Arbitrum that lets users deposit USDC and automatically gain exposure to yield strategies with real-time transparency. Instead of leaving capital idle or manually chasing yields, Plexi aggregates deposits, allocates them into a strategy, tracks TVL, shares, and hedge ratios on-chain, and provides a clean dashboard to monitor performance. The current MVP focuses on core vault mechanics—deposit, withdraw, and live stats—serving as the foundation for future integrations with protocols like GMX (GLP) and Hyperliquid for real yield and automated hedging.

描述

try out plexi :- https://plexi-frontend.vercel.app/

Plexi is a next-gen composable ERC-4626 vault built on Arbitrum, designed to make on-chain yield farming simple, transparent, and capital-efficient. Instead of leaving USDC idle or manually hopping between protocols, users can deposit into Plexi and let the vault handle capital aggregation, strategy execution, and performance tracking — all visible in real-time.

How It Works

Vault (ERC-4626):

  • Accepts USDC deposits from users

  • Mints vault shares proportional to deposits

  • Tracks total assets and user balances

  • Enables withdrawals at any time

Strategy Contract:

  • Tracks total invested capital

  • Provides functions like totalInvested() and getHedgeRatio()

  • Handles basic rebalancing and emergency withdraws

  • Currently a mock strategy, but designed for future integrations

Frontend (Nextjs):

  • Minimal, clean dashboard

  • Wallet connect flow

  • Displays TVL, total supply, strategy investment, hedge ratio, and user shares live from the blockchain

  • Real-time updates using Wagmi & Viem

Backend (Next.js + MongoDB):

  • Exposes API routes for fetching aggregated vault data

  • Implements server-side rendering (SSR) for SEO & faster load

  • Caches blockchain reads for performance (10s TTL)

Core Features (MVP)

  • ✅ Deposit & Withdraw — Users can seamlessly move USDC in/out of the vault

  • ✅ Vault Shares Tracking — Users see their share of the vault in real-time

  • ✅ Live Stats Dashboard — TVL, strategy invested, hedge ratio, and more

  • ✅ Emergency Withdraw — Safety switch to exit strategy funds instantly

  • ✅ Arbitrum Sepolia Deployment — Live testnet deployment for experimentation

Future Roadmap

🔗 Protocol Integrations:

  • GMX (GLP): Earn real yield from blue-chip protocols

  • Hyperliquid: Delta-neutral hedging via perpetuals

🤖 Automation:

  • Auto-rebalancing strategies

  • Auto-compounding of rewards

  • Dynamic hedge ratio adjustment

📊 Advanced Analytics:

  • Historical performance charts

  • Strategy PnL tracking

  • Yield APY projections

Why Plexi?

  • Composability: Built on ERC-4626, so it can plug into DeFi money legos

  • Transparency: Every stat (TVL, shares, investments) is on-chain and verifiable

  • Modularity: Strategy layer can evolve to support any yield source

  • User Experience: Minimal, clean, and degen-friendly

黑客松進展

During the buildathon, we successfully bootstrapped Plexi into a working MVP on Arbitrum Sepolia, focusing on building a fully functional ERC-4626 vault with a composable strategy layer. We deployed and tested the core smart contracts — Vault, Strategy, and MockUSDC — and resolved critical issues around withdrawals, share accounting, and total asset tracking. The frontend was built using Nextjs with a minimal dashboard that fetches live data (TVL, total supply, strategy invested funds, and hedge ratio) directly from the blockchain. On the backend, we implemented Next.js SSR APIs with MongoDB caching to serve vault stats efficiently. End-to-end integration tests were run on Sepolia to verify deposit, rebalance, and withdraw flows, all of which passed successfully. While the strategy currently uses a simplified mock implementation, we laid the groundwork for future integrations with GMX (GLP yield farming) and Hyperliquid (perpetual hedging). Overall, Plexi has progressed from idea → smart contract deployment → functional UI/UX, making it a polished, testnet-ready MVP with clear next steps for protocol integration.

籌資狀態

Plexi is fully bootstrapped and live on Arbitrum Sepolia testnet, with core vault mechanics, strategy layer, and frontend dashboard already deployed and tested end-to-end. Having proven the MVP, we are now looking to raise a pre-seed round to fund security audits, protocol integrations (GMX + Hyperliquid), mainnet deployment, and initial liquidity bootstrapping. Our goal is to turn Plexi from a testnet prototype into a production-ready, capital-efficient yield product for the Arbitrum ecosystem.
