find-arbitrage-opps

Find arbitrage opportunities across all Hummingbot-connected exchanges by comparing prices for a trading pair, accounting for fungible tokens (e.g., BTC = WBTC, USDT = USDC).

Prerequisites

Hummingbot API must be running with exchange connectors configured:

bash <(curl -s https://raw.githubusercontent.com/hummingbot/skills/main/skills/lp-agent/scripts/check_prerequisites.sh)

DEX Support

By default the script queries CEX connectors via the Hummingbot API. Add --dex to also fetch prices from:

DEX	Chain	Default Network
Jupiter	Solana	mainnet-beta
Uniswap	Ethereum	mainnet
PancakeSwap	Ethereum (BSC)	bsc

DEX prices are fetched directly via the Hummingbot Gateway. Make sure Gateway is running on http://localhost:15888 (or set GATEWAY_URL).

⚠️ BTC markets are only available to Australian residents on some exchanges. A warning is printed automatically when BTC/WBTC/cbBTC is included in the search.

Workflow

Step 1: Define Token Mappings

User specifies the base and quote tokens, including fungible equivalents:

• Base tokens: BTC, WBTC, cbBTC (all represent Bitcoin)
• Quote tokens: USDT, USDC, USD (all represent USD)

Step 2: Find Arbitrage Opportunities

# Basic - CEX only
python scripts/find_arb_opps.py --base BTC --quote USDT

# Include fungible tokens
python scripts/find_arb_opps.py --base BTC,WBTC --quote USDT,USDC

# Include DEX prices (Jupiter + Uniswap via Gateway)
python scripts/find_arb_opps.py --base SOL --quote USDC --dex
python scripts/find_arb_opps.py --base ETH,WETH --quote USDT,USDC --dex

# Minimum spread filter
python scripts/find_arb_opps.py --base SOL --quote USDC --dex --min-spread 0.1

# Filter to specific CEX connectors
python scripts/find_arb_opps.py --base BTC --quote USDT --connectors binance,kraken,coinbase

Step 3: Analyze Results

The script outputs:

• Prices from each CEX and DEX source
• Best bid/ask across all sources
• Arbitrage spread (buy low, sell high)
• Recommended pairs for arbitrage

Script Options

python scripts/find_arb_opps.py --help

  SOL / USDC Arbitrage Scanner
  DEX: Jupiter (Solana mainnet-beta), Uniswap (Ethereum mainnet)
============================================================

  Lowest:  binance                   $132.4500
  Highest: jupiter (DEX)             $132.8900
  Spread:  0.332% ($0.4400)

Environment Variables

export HUMMINGBOT_API_URL=http://localhost:8000
export API_USER=admin
export API_PASS=admin
export GATEWAY_URL=http://localhost:15888   # for DEX prices

Scripts check for .env in: ./hummingbot-api/.env → ~/.hummingbot/.env → .env

Requirements

• Hummingbot API running (for CEX prices)
• Gateway running (for DEX prices with --dex flag)
• Exchange connectors configured with API keys
