sAVAX Arbitrage Finder

Real-time comparison tool to find the best way to acquire sAVAX (Staked AVAX) on Avalanche C-Chain.

Live App: https://avasnap.github.io/savax-compare/

What It Does

Compares two methods of acquiring sAVAX:

• Buy on DEX: Swap AVAX for sAVAX on decentralized exchanges
• Mint via Protocol: Stake AVAX directly through BENQI to receive sAVAX

The app shows you which method gives you more sAVAX for your AVAX, identifying arbitrage opportunities in real-time.

Features

• ✅ Real-time DEX prices from DexScreener API
• ✅ On-chain protocol rates from BENQI sAVAX contract
• ✅ Percentage-based arbitrage analysis
• ✅ No API keys or external dependencies required
• ✅ Fully client-side, works entirely in your browser

Data Sources

• DEX Prices: Fetched from DexScreener API (highest liquidity pool on Avalanche)
• Protocol Rate: Direct RPC call to BENQI sAVAX contract at 0x2b2C81e08f1Af8835a78Bb2A90AE924ACE0eA4bE

Tech Stack

How It Works

1. Fetches DEX Price: Queries DexScreener for sAVAX/AVAX pairs on Avalanche, selects the pool with highest liquidity
2. Fetches Protocol Rate: Calls getPooledAvaxByShares(1e18) on BENQI sAVAX contract via Avalanche RPC
3. Calculates Arbitrage: Compares how much sAVAX you'd receive from each method
4. Recommends Best Option: Shows which method gives you more sAVAX and by what percentage

Example Calculation

For 1000 AVAX:

• DEX: 1000 / 1.2317 AVAX = 811.89 sAVAX
• Protocol: 1000 / 1.2368 AVAX = 808.56 sAVAX
• Result: Buy on DEX, receive 3.33 sAVAX (0.41%) more

Deployment

Automatically deployed to GitHub Pages on every push to main:

1. GitHub Actions runs npm run build
2. Deploys dist/ folder to gh-pages branch
3. GitHub Pages serves from gh-pages branch
4. Changes go live in ~2-3 minutes
