Cardano DEX Integration

Discover Cardano DEX liquidity pools, fetch aggregated on-chain prices, and compare DEX vs CEX pricing for Cardano native tokens.

Overview

OpenMM integrates with Cardano DEX liquidity pools via the Iris Protocol, aggregating data from multiple decentralized exchanges on Cardano. This skill covers read-only price discovery and pool analysis — no on-chain trading is involved.

Supported tokens: SNEK, INDY, NIGHT, MIN

Supported DEXes (via Iris Protocol): SundaeSwap, Minswap, WingRiders

Credentials

No exchange API keys are required for Cardano DEX operations — all pool data is public on-chain. However, the price-comparison command also fetches CEX prices, which may require exchange credentials to be configured. See the openmm-portfolio skill for exchange credential setup.

Aggregated DEX Pricing

Get the current aggregated price for a Cardano native token. Prices are calculated from on-chain DEX pool reserves, weighted by total value locked (TVL).

openmm pool-discovery prices SNEK
openmm pool-discovery prices INDY
openmm pool-discovery prices NIGHT

How Price Calculation Works

1. TOKEN/ADA price is fetched from on-chain DEX pools (SundaeSwap, Minswap, WingRiders), weighted by TVL
2. ADA/USDT price is fetched from CEX price feeds (MEXC, other aggregators)
3. TOKEN/USDT = TOKEN/ADA x ADA/USDT

This gives a USD-denominated price for Cardano tokens that do not have direct USDT pairs on all exchanges.

Pool Discovery

Discover liquidity pools for a specific token across all supported Cardano DEXes.

# Find all pools for a token
openmm pool-discovery discover SNEK

# Find pools for INDY
openmm pool-discovery discover INDY

# Filter by minimum liquidity (TVL in ADA)
openmm pool-discovery discover SNEK --min-liquidity 50000

# Discover NIGHT pools with minimum liquidity
openmm pool-discovery discover NIGHT --min-liquidity 10000

Pool discovery returns:

• Pool address and DEX source
• Token pair (e.g., SNEK/ADA)
• Reserves for each token in the pool
• Total value locked (TVL)
• Implied price from pool reserves

DEX vs CEX Price Comparison

Compare the aggregated DEX price against CEX prices to identify arbitrage opportunities or price discrepancies.

openmm price-comparison --symbol SNEK
openmm price-comparison --symbol INDY

This command fetches:

• Aggregated DEX price (from Cardano pools via Iris Protocol)
• CEX price (from exchanges like MEXC, Bitget where the token is listed)
• Price difference and percentage spread between DEX and CEX

MCP Tools

Examples

Get aggregated price:

Tool: get_cardano_price
Parameters: { "symbol": "SNEK" }

Discover pools with minimum liquidity:

Tool: discover_pools
Parameters: { "symbol": "INDY", "minLiquidity": 50000 }

Iris Protocol Integration

The Iris Protocol is a Cardano data aggregation layer that indexes liquidity pools across multiple DEXes. OpenMM uses Iris to:

• Discover all active pools for a given token
• Fetch real-time reserve data for price calculation
• Aggregate prices across pools weighted by TVL
• Filter pools by minimum liquidity thresholds

Indexed DEXes:

• SundaeSwap — one of the earliest Cardano DEXes
• Minswap — largest Cardano DEX by TVL
• WingRiders — Cardano DEX with concentrated liquidity

Tips for Agents

1. Use for arbitrage analysis — compare DEX and CEX prices with price-comparison to find opportunities
2. Compare before trading on CEX — check if the DEX price is significantly different before placing CEX orders
3. Filter low-liquidity pools — use --min-liquidity to focus on pools with meaningful TVL
4. No API keys required — Cardano DEX data is public; no exchange credentials needed for pool discovery and pricing
5. Prices are estimates — DEX prices reflect pool reserves, not executable quotes; slippage applies for large trades
6. TOKEN/USDT depends on ADA/USDT — if ADA price moves significantly, all token USDT prices will shift accordingly
