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
