Polymarket Arbitrage Bot FAQ — Risk, Custody, Fees

Answers to every common question about the Polymarket Arbitrage Bot: is arbitrage risk-free, do you custody funds, where is Polymarket allowed, what about Polygon gas, and how the bot handles partial fills and leg risk.

Is the $7.62 minimum guaranteed per trade real?

Yes — but it's a floor, not a ceiling. We never publish a signal that doesn't clear $7.62 of net edge after Polymarket's taker fees on $1,000 of capital. Many signals clear $20-40+. The math is locked the moment both legs fill at our price; resolution can't take it from you.

How is 40ms possible when competitors are ~800ms?

Three reasons: paid Polymarket API tier (most bots use the free public endpoint that's heavily rate-limited), co-located scanner near Polymarket's relayer, and signed-batched FAK orders submitted in a single network round-trip rather than serial leg-then-leg.

Is this risk-free?

No financial product is risk-free. The spread we lock in is mathematical, but you still face resolution disputes, partial fills below the minimum, and execution timing risk — which is precisely why latency matters. We document every risk in the disclosure.

Do I need to give you my keys?

No. The bot is non-custodial. You connect your own wallet, we send signed transactions to your wallet for approval, and your funds never leave your control.

Where is Polymarket trading allowed?

Polymarket geo-blocks 30+ countries including the United States (with a separate CFTC pathway), the United Kingdom, France, Germany, Italy, and Australia. Read our geographic restrictions overview before depositing.

Is PolyArb affiliated with Polymarket?

No. PolyArb is an independent project. We use Polymarket's public APIs and do not represent or have any business relationship with Polymarket.

What chains do you support?

Polygon (chain ID 137) only — that's where Polymarket lives.

Do you store my wallet address?

No. We do not custody funds, store private keys, or ask you to sign anything. The only data we keep is your email, Telegram handle, and the on-chain transaction hash you submit at checkout.
