Get your relayer running in 5 minutes. No technical knowledge required — just your CXO reward address and a monthly payment.
Go to cargoxrelayer.com/app/register. Fill in your email and password, and pick your plan — Managed · BASIC or Managed · PRO.
After logging in, you'll see the Welcome to Managed Relayer Service screen. Click the + Add Relayer button to start setting up your first relayer.
In the Add Managed Relayer dialog, enter your CXO Reward Address — this is the Polygon wallet where you hold your CXO tokens (minimum 50,000 CXO required for staking).
As you type, the system will suggest matching addresses with their current CXO balance. The Payment Details section shows the monthly fee and the address where you should send payment.
After clicking Subscribe, your relayer appears with status PENDING. Now send the monthly fee (in USDC or CXO) to the displayed payment address.
Once the transaction is confirmed on-chain, click Verify Payment. The system will check the Polygon blockchain for your transfer and activate your relayer automatically.
Once payment is verified, your relayer starts automatically and you'll see full real-time statistics: MATIC balance, CXO balance, documents relayed, confirmation rate, gas usage, and more.
The dashboard updates in real-time via WebSocket — you can monitor your relayer performance 24/7 including from your phone (installable as PWA app).
All three plans use the same on-chain relayer contract — the differences are operational. Pick the one that matches how hands-on you want to be. Live per-relayer pricing is in the cost FAQ below.
| Basic | Pro | User | |
|---|---|---|---|
| Fully managed | Competition | Self-service | |
| Who is it for | FIX traders & hands-off CXO holders | Relayers holding 200 000+ CXO who want contested racing | Sysadmins & dedicated operators |
| Signing wallet | Provider pool | Bring your own (generated or imported) | Bring your own (you fully control) |
| POL gas costs | We cover — nothing to monitor or top up | You pay from your wallet | You pay from your wallet |
| Reserved docs | Always processed | Always processed | Always processed |
| Contested racing | – not included — reserved documents only | ✓ Advanced racing — see Dynamic Boost row | Standard static boost (you tune the level) |
| Dynamic Boost | – not available | ✓ included — live market gas pricing, multi-RPC parallel broadcast, smart auto-pause, IQR outlier filtering | – not available (Pro-only feature) |
| RPC endpoints | Managed by us | Managed by us | You configure (own paid nodes) |
| Configuration | Reward address only | Reward address + signing wallet | Reward address + wallet + RPC + boost + refresh interval |
| Fee (per price list) | Highest per relayer — pay monthly, or ahead until any date you choose (prorated) | Mid (lower than Basic in exchange for self-funded POL); same flexible billing | Lowest per relayer — also billed per the price list, covers infrastructure only |
| Switching | Self-service upgrade to Pro anytime; downgrade is admin-assisted | Downgrade to Basic via admin request | Account role switch via My Settings |
Per-relayer prices come from the admin-managed tier table and are volume-discounted — running multiple relayers under one account drops the price per relayer on every plan. Exact figures (USDC + locked CXO equivalent) are shown live in the “How much does the Managed Service cost?” FAQ entry below.
It's the Polygon wallet address where you hold your CXO tokens. Your CXO tokens must be on the Polygon network (not Ethereum mainnet). You need at least 50,000 CXO staked to be eligible for relayer rewards. This is the address that receives relay rewards when your relayer wins a document.
Every Managed relayer runs on one of two plans — you pick the flag when you register:
You pay monthly, or ahead until any date you choose (the cost is prorated from your per-relayer price). Both plans support volume discounts — running multiple relayers drops the per-relayer price. The exact tier-based price is shown during signup and on your dashboard. You can pay in USDC (1:1 with USD) or CXO (current market rate, locked at the time the admin last published tier prices).
Self-service (User) accounts are also priced per the same price list — a per-relayer monthly fee, the smallest of the three plans.
Basic is the simplest option — we handle everything, including paying for blockchain gas (POL). Your relayer processes reserved documents only: the ones assigned to you, guaranteed, with no racing. POL never becomes your problem — nothing to monitor, nothing to top up.
Pro costs less per month — in exchange you manage one thing yourself: the signing wallet's POL balance. On top of reserved documents, Pro relayers also race for contested documents with the full advanced algorithm (dynamic gas pricing, market-aware bidding, smart auto-pause). Racing burns gas per attempt, so it pays off at volume — Pro is designed for relayers holding 200 000+ CXO.
You can switch from Basic to Pro anytime via the dashboard. Switching back to Basic is admin-assisted to make sure your funds and settings are handled correctly.
Pro makes sense if you:
Stay on Basic if you prefer a "set and forget" experience: reserved documents are processed in full, and you never monitor POL or send native tokens anywhere.
No. Basic processes reserved documents only, and the gas those relays cost is entirely our concern — there is no balance to watch, no budget to manage, and nothing to top up. If you want contested racing, that's the Pro plan, where you fund the signing wallet's POL yourself.
After upgrading to Pro (or signing up directly as Pro), you'll see your signing wallet address on the dashboard. Send POL (Polygon native token, sometimes called MATIC) to that address from any exchange or wallet. Recommended starting balance: 5–20 POL depending on race activity. The dashboard shows your MATIC balance — top up when it gets low.
If you generated a fresh wallet during upgrade, double-check you saved the private key in a safe place — we encrypt and store it server-side but cannot show it to you again later.
Payments are accepted in USDC and CXO exclusively on the Polygon network. Do not send tokens on Ethereum mainnet or any other chain. The system verifies ERC-20 Transfer events on Polygon — tokens sent on a wrong network will not be detected and cannot be recovered.
If payment is not verified within 30 days of the previous payment, your relayer is automatically paused. No data is lost — simply send a new payment and click Verify Payment to resume your relayer.
Yes! You can add multiple relayers, each with a different CXO reward address. Each relayer requires its own monthly subscription and payment — but the more relayers you run, the lower the per-relayer fee on both plans.
The Managed Service (Basic or Pro plan) runs everything for you in our infrastructure — you only need a CXO reward address and a payment method. Self-Service gives you full control over the relayer configuration, signing wallet, and RPC endpoints, but each new Relayer carries a small monthly subscription (see the User plan in the cost FAQ above — admin-configured, currently shown live).
Within Managed Service: Basic = reserved documents only, we cover POL gas entirely; Pro = reserved + contested racing, you cover POL gas with your own signing wallet (in exchange for a lower fee + the advanced algorithm; designed for relayers holding 200 000+ CXO). For Self-Service (User): you supply the signing wallet and fund POL yourself, and you pay a per-Relayer fee per the same price list. Relayers that already existed before the fee was introduced stay free.
Absolutely. Your CXO tokens stay in your own wallet at all times. The relayer only uses a separate signing wallet (provided by us) to submit relay transactions. Your reward address is never given a private key — it only receives rewards.
Yes, you can cancel anytime from the dashboard. Your relayer will be stopped and the signing wallet returned to the pool. There are no long-term commitments.
Create your account and have your relayer running in minutes. No technical expertise needed.
