What it is

Multi-Chain Hub is a single page covering five operations across 15 supported networks. You connect one EVM wallet address (persisted locally) to pull a cross-chain portfolio snapshot, watch live gas prices side-by-side, scan for cross-chain arbitrage opportunities with net-profit math after gas, open per-chain detail drawers to see available DEXes and block times, and resolve any token contract address to its metadata. Supported chains: Ethereum, BSC, Polygon, Arbitrum, Base, Avalanche, Optimism, Solana, Cronos, Fantom, zkSync Era, Mantle, Linea, Scroll, Blast.

How to think about it

Most users start by pasting one wallet address — that unlocks the portfolio table + arbitrage rows relevant to your holdings. The Gas Price Monitor is useful even without a connected address as a planning tool: do swaps when your target chain is in the green band, not the red one.

Step-by-step

  1. Save your wallet address once

    My Wallet card → paste an EVM address (0x… 40-hex format). Validation runs inline. Click Save and the page caches it in localStorage as mcn_bot_wallet_address — no need to re-enter on future visits. Same address feeds the Portfolio table and the per-chain breakdowns. Solana balances pull separately via the Solana RPC fanout.

  2. Read the Portfolio Summary cards

    Three cards: Total Value USD (sum across all chains), Active Chains (currently 15), Largest Chain (where most of your capital sits). If Largest Chain is unexpected, that's a rebalance signal — most users want their largest exposure on the chain they actively trade on, not on a stranded testnet.

  3. Use the Gas Price Monitor as a swap-timing tool

    Live gwei readings across every chain. The "Cheapest" highlight is auto-computed — useful when you have flexibility on which chain to swap on (e.g., bridge-then-swap routes). Cards refresh every ~30 seconds. Gwei is displayed at 2 decimals normally, 3-6 decimals for sub-1-gwei chains (Polygon, Solana, Base).

  4. Check the Cross-Chain Arbitrage Detector

    Detects price spreads between DEXes on different chains (or same chain, different DEX). Each opportunity shows: source / target chain, price diff %, gross profit, total cost (gas both sides + slippage estimate), and NET PROFIT. Only act on positive net rows — anything <0.20% is usually wiped by slippage and MEV competition. Refreshes every ~60 seconds.

  5. Open a Chain Detail drawer for DEX selection

    Click any chain row in the support grid. The drawer shows: block time, status, all DEXes available on that chain with their fee bands. Examples — Ethereum: Uniswap V3 (0.05-1%), V2 (0.3%), SushiSwap (0.3%), Curve (0.04%). Base: Aerodrome (0.05-1%), Uniswap V3 (0.05-1%), BaseSwap (0.25%). Pick the lowest-fee DEX that has the liquidity for your trade size.

  6. Resolve a token via Token Discovery

    Paste a contract address + pick the chain. The resolver returns name, symbol, decimals, current price, basic liquidity. Use this BEFORE adding any token to a DEX bot — confirms the address matches the token you think it is and isn't a copycat. Solana addresses use base58 format (no 0x prefix); EVM addresses are 0x + 40 hex.

  7. Read the full Cross-Chain Portfolio table

    Below the summary cards. Per-chain rows: chain name + avatar, USD value, % of total. Sortable by value. Use this when sizing new positions — if Ethereum is 70% of your capital, the next DEX bot probably belongs on Arbitrum or Base for diversification, not back on mainnet.

Tips & pitfalls

  • Wallet address is stored ONLY in your browser localStorage — never sent to backend storage. Clearing browser data wipes it; re-enter to restore.
  • Arbitrage rows with positive gross profit but NEGATIVE net profit are tracking signals — they show you which pairs are tight, not which to trade. Cross to net-positive before acting.
  • Polygon, Arbitrum, Base, and zkSync Era are best for learning and small-size testing — gas fees are pennies vs Ethereum's dollars.
  • Avoid bridging just to capture a 0.30% arbitrage spread — bridge fees + bridge time (often 5-30 min on optimistic rollups, hours on canonical) eat the edge. Same-chain DEX-to-DEX arbitrage is the cleaner play.
  • Token Discovery is a metadata lookup, NOT a safety check. Pair with Token Launch Scanner (Elite) before sending any real capital to an unfamiliar contract.
  • Cross-chain portfolio value is a snapshot — price feeds settle with 30-60s latency. Use it for allocation decisions, not for tax reporting (Tax Report has the strict accounting view).
