Most airdrop hunters know what they earned. Almost none of them know what they actually spent to get there.
Gas fees, bridge costs, swap fees they quietly eat into profits.

What is RektoMeter?
RektoMeter is a smart airdrop portfolio journal. It lets you track every project you're farming with multiple wallets, real-time prices from Pyth Network, expense logging, income tracking, and automatic P&L calculation.
The Real ROI Formula
Most people calculate airdrop ROI wrong:
❌ Wrong: Airdrop Value = Profit
✅ Right: Net P&L = Airdrop Value + Income − Expenses
ROI % = Net P&L ÷ Expenses × 100
Real example — Arbitrum:
- Gas + bridge expenses: $45
- Airdrop received: $2,800
- Net P&L: +$2,755 (6,122% ROI)
Without tracking, you'd just see "$2,800" and call it a day. With RektoMeter, you see the full picture.
How Pyth Network Powers It
RektoMeter uses Pyth Network's Hermes API to pull institutional-grade real-time prices for 500+ crypto assets.
Every time you add a holding — say, 2 ETH that you used as capital — RektoMeter fetches the live price from Pyth and shows you the unrealized P&L in real-time.
// Fetching live prices from Pyth Hermes API
const params = new URLSearchParams();
feedIds.forEach(id => params.append('ids[]', id));
const res = await fetch(
`https://hermes.pyth.network/v2/updates/price/latest?${params}`
);
const data = await res.json();
data.parsed.forEach(item => {
const price = parseFloat(item.price.price)
* Math.pow(10, item.price.expo);
prices[item.id] = price;
});
Prices update every 15 seconds — the same data used by DeFi protocols and institutional traders, now in your airdrop journal.
Why Pyth instead of CoinGecko or CoinMarketCap? Because Pyth data comes directly from market makers like Binance, Bybit, and Jane Street. It's faster, more accurate, and designed for financial applications.

-
EVM wallets (starts with
0x...) - SVM wallets (Solana base58 format)
📈 Live Holdings via Pyth
Search any of 500+ crypto assets. Unrealized P&L updates in real-time using Pyth price feeds.
💸 Expense Log

What I Learned
1. Pyth's Hermes API is genuinely easy to use.
No API key needed for price feeds. Two endpoints cover everything — fetch available feeds, then fetch live prices. The data quality is noticeably better than free alternatives.
2. The airdrop tracking space is underserved.
Most tools focus on finding airdrops. Almost nothing exists to track the actual profitability of farming campaigns across multiple wallets with expense tracking.
3. localStorage is underrated for MVP.
No backend, no auth, no database costs. Users' data stays in their own browser. For a journaling tool, this is actually ideal — it's private by design.
What's Next
RektoMeter v2 roadmap:
- Database sync (Supabase) for multi-device support
- Historical price lookup via Pyth — auto-fill buy price based on transaction date
- Candlestick charts using Pyth OHLC data
- CSV export for tax reporting
