Token Pairs Being Monitored - Complete List

Summary

The MEV bot discovers pools for 45 unique token pairs across 10 major Arbitrum tokens, resulting in 50-60+ individual pools when accounting for multiple DEXes and fee tiers per pair.

Why 50+ Pools from 45 Pairs?

Each token pair can have multiple pools across different:

1. DEX Protocols (6)

  • Uniswap V3 - Concentrated liquidity
  • Uniswap V2 - Classic AMM
  • SushiSwap - Fork of V2
  • Camelot - Arbitrum-native DEX
  • Curve - Optimized for stablecoins
  • Balancer - Multi-asset pools

2. Fee Tiers (Uniswap V3)

  • 0.05% - Stablecoin pairs
  • 0.3% - Most pairs (standard)
  • 1% - Exotic/volatile pairs

Example: WETH/USDC Pools

Token Pair: WETH/USDC
├─ Uniswap V3 (0.05% fee) → Pool #1
├─ Uniswap V3 (0.3% fee)  → Pool #2
├─ Uniswap V3 (1% fee)    → Pool #3
├─ SushiSwap              → Pool #4
└─ Camelot                → Pool #5

Result: 1 pair = 5 pools

High-Priority Pairs ()

These pairs typically have the highest liquidity and trading volume:

Rank Pair Why High Priority
1 WETH/USDC Highest volume, tightest spreads
2 WETH/USDT Second highest volume
3 WETH/ARB Native token, high activity
4 USDC/USDT Stablecoin arbitrage opportunities
5 USDC/ARB High ARB trading volume
6 USDC/DAI Stablecoin triangular arbitrage
7 USDT/DAI Additional stablecoin route
8 WETH/WBTC BTC-ETH correlation trades
9 WETH/GMX GMX is popular on Arbitrum
10 USDC/GMX GMX primary liquidity

Discovery Process

CREATE2 Calculation

For each token pair, the bot:

  1. Calculates deterministic pool addresses using CREATE2
  2. Checks all 6 DEX factory contracts
  3. Validates pools exist on-chain
  4. Fetches pool metadata (reserves, liquidity)
  5. Caches valid pools to data/pools.json

Pool Validation

// For each token pair
for i := 0; i < len(tokenList); i++ {
    for j := i + 1; j < len(tokenList); j++ {
        // Discover all pools for this pair across all DEXes
        pools := DiscoverPoolsForTokenPair(token0, token1)

        // Could find 1-5 pools per pair
    }
}

Expected Pool Distribution

Pool Type Count Notes
Uniswap V3 (0.3%) 20-25 Most common
Uniswap V3 (0.05%) 8-10 Stablecoin pairs
Uniswap V3 (1%) 3-5 Volatile pairs
SushiSwap 10-12 Popular pairs
Camelot 8-10 Arbitrum native
Curve 2-3 Stablecoin only
Total 50-65 Varies by liquidity

Arbitrage Opportunities

Two-Hop Arbitrage

Example: Price divergence between DEXes

Buy WETH on Uniswap V3 (0.3%) → Sell WETH on SushiSwap

Triangular Arbitrage

Example: Multi-hop with price inefficiencies

USDC → WETH (Uniswap) → ARB (Camelot) → USDC (SushiSwap)

Stablecoin Arbitrage

Example: Peg deviation trading

USDC → USDT (Curve 0.05%) → DAI (Uniswap) → USDC (SushiSwap)

Monitoring Strategy

Real-Time

  • Listen for swap events on all 50+ pools
  • Calculate price divergences across DEXes
  • Detect arbitrage opportunities instantly

Periodic

  • Re-discover pools every 24 hours
  • Update pool metadata (reserves, liquidity)
  • Remove inactive/deprecated pools

Dynamic

  • Add new tokens as they gain volume
  • Monitor for new pool deployments
  • Adjust based on profitability data

Mathematical Proof

Combination Formula:

C(n,k) = n! / (k! × (n-k)!)

For 10 tokens, choosing 2 at a time:
C(10,2) = 10! / (2! × 8!)
        = (10 × 9) / (2 × 1)
        = 45 unique pairs

Pool Multiplier:

45 pairs × 1.2 average pools per pair = ~54 pools
(Some pairs have 1 pool, some have 3-5)

Future Expansion

Short Term

  • Add 5 more tokens (60 pairs → 75+ pools)
  • Include Arbitrum Nova pairs
  • Monitor USDC.e (bridged USDC) separately

Long Term

  • Cross-chain pairs (Arbitrum ↔ Ethereum)
  • Exotic pairs with lower volume
  • LP token arbitrage
  • Options protocol integration
