Beefy Yield-Fidelity Monitor
A proposal for real-time Net Realized APY transparency: break-even calculator, vault drift monitoring, and multi-chain yield health for the Beefy Cowmoonity.
- Problem
- The Gas Gap: users depositing small amounts often don't realize that L2 gas fees and Beefy's performance fees can make net return negative for the first 30+ days. Strategy Drift: realized APY depends on harvest frequency; if a vault is harvested less often due to low TVL, users earn less than the "Target APY" shown on the UI.
- Solution
- A lightweight, high-performance monitoring layer that provides Yield Fidelity metrics: a user-facing break-even calculator, a DAO-facing vault drift dashboard, and multi-chain alerts so users and strategists see true net yield.
Overview
What it is: A proposal and demo, not a shipped product. It describes a monitoring dashboard that gives real-time transparency into Net Realized APY for Beefy vaults, and the demo at yield.rahilbhavan.com shows the intended experience. Proposed stack: Next.js, Supabase, the Beefy API, and Vercel.
Why it matters: Users depositing small amounts often don’t realize that L2 gas and Beefy’s performance fees can make net return negative for the first 30+ days (the Gas Gap). Realized APY also depends on harvest frequency, so a vault harvested less often because of low TVL earns less than the Target APY shown in the UI (Strategy Drift).
Impact: The goal is to reduce user churn from “gas-shock” and give the DAO an internal health check for vault strategy efficiency. This page lays out the requirements, architecture, KPIs, and roadmap for that work; the demo is the MVP of the user-facing piece.
Target audience
- Retail users: Need to know their break-even time before depositing.
- DAO strategists: Need to identify vaults where actual growth (price-per-share) is lagging behind projected APR.
Functional requirements
FR1: Break-Even Calculator (Next.js)
User-facing component: users enter intended deposit ($) and select a vault. The system fetches current network gas prices and computes how many days of compounding it takes to offset entry/exit gas and become profitable.
- Input: Deposit amount ($), selected vault, current network gas.
- Logic: Break-Even Days = (Gas Entry + Gas Exit) / (Daily Yield - Daily Fees).
- Output: Countdown or days until the user is “in the green.”
FR2: Yield Health Dashboard (Supabase)
DAO-facing monitoring tool. Store pricePerFullShare (PPS) daily; compute the delta between expected yield (from Beefy API) and actual growth (from PPS change). Visualize “Yield Curve” vs “Efficiency Floor.”
- Historical tracking: Daily PPS per vault.
- Drift analysis: Flag vaults where realized yield lags target APR (e.g. drift > 10% for 48+ hours).
- Storage: Supabase caches historical performance for faster loading than direct subgraph queries.
FR3: Multi-Chain Alerts
Heat map of Beefy-supported chains (Base, Arbitrum, Polygon, etc.) showing which networks currently have the lowest “Friction” (gas vs yield ratio). Surfaces the most efficient vaults by network for the Cowmoonity.
- Feature: Per-chain gas vs yield comparison.
- Output: Weekly “Yield Health” summary (e.g. via Vercel cron) for Discord or internal use.
Technical architecture
| Layer | Tech | Responsibility |
|---|---|---|
| Frontend | Next.js + Tailwind | Responsive UI and break-even calculator components. |
| Database | Supabase (PostgreSQL) | Caching vault metadata and historical PPS (price per share) values. |
| API integration | Beefy API + Ethers.js | Fetching live APR, TVL, and on-chain gas prices. |
| Automation | Vercel Cron / GitHub Actions | Daily PPS scrapers to keep drift analysis fresh. |
Success metrics (KPIs)
- User adoption: % of unique visitors using the calculator before clicking “Deposit.”
- Accuracy: Drift analysis error margin < 0.5% compared to on-chain vault growth.
- Engagement: Increase in average deposit size by steering users away from gas-negative positions.
Implementation roadmap
- Milestone 1: MVP of the Next.js break-even calculator on one chain (e.g. Base).
- Milestone 2: Supabase schema design and initial PPS data scraping for top 50 vaults.
- Milestone 3: Full deployment of the Yield Fidelity dashboard with DAO-facing analytics.
Phased timeline: Week 1-2 (data layer + Beefy API), Week 3 (logic layer + net-yield algorithm), Week 4 (frontend/MVP on Vercel).
Why this matters for Beefy
- Retention: Users stay longer when they understand their actual profit margins.
- Operational excellence: The DAO gets an early-warning system for vaults that need strategy adjustments or higher harvest frequency.
- Student contribution: Proposed as a summer internship or contributor role (e.g. U-M) to bridge DeFi tooling and production-ready code.
