1. 01
   Get a DOT to ARB quote

   Enter how much Polkadot you want to convert. You see the live DOT to ARB rate, both fees and the exact Arbitrum you will receive before you commit.

2. 02
   Send your Polkadot

   You get a Polkadot (DOT) deposit address and an exact amount. Send it from any Polkadot wallet — scanning the QR code fills in both where your wallet supports it.

3. 03
   Receive Arbitrum (ARB)

   Once the DOT deposit confirms on-chain, Arbitrum is sent to the Arbitrum address you gave. Track it on the swap’s status page, no login needed.

What does the DOT to ARB rate mean?

It is how much Arbitrum (ARB) you receive for each Polkadot (DOT) you send, taken from live market prices at the moment you ask for a quote. The rate moves with the market, so you have 90 seconds to accept a quote and create the swap; the widget refreshes it automatically if you take longer. Funding the swap once it exists has its own separate deadline, shown on your swap page.

How do I convert DOT to ARB?

Enter the amount of DOT in the widget, choose ARB as what you receive, and give a Arbitrum address. You are shown a deposit address and an exact DOT amount; send that amount and the ARB is paid to your address once the deposit confirms. No account is needed at any step.

What are the fees to exchange DOT for ARB?

Two, both shown in the quote before you send: a swap fee of 0.5% of the amount, and a network-fee charge for the Arbitrum payout transaction. There is nothing added afterwards — the ARB amount in the quote is the ARB amount that arrives.

What is the minimum DOT/ARB exchange amount?

$100 worth, shown in the widget as an amount of DOT at the current rate. There is no maximum imposed by the site beyond available Arbitrum liquidity, and no verification at any size.

Do I need an ID to swap DOT to ARB?

No. There is no KYC, no account and no email required. A swap is identified by its link, which shows its status without logging in. Creating an account is optional and only keeps your swap history in one place.

How long do DOT to ARB swaps take?

Polkadot deposits usually confirm in a few minutes, after which the deposit is verified on-chain. Swap times vary by asset and by how quickly its network confirms. Your swap status page shows the current stage throughout the process.

Which Arbitrum address should I give?

Any address in a format Arbitrum accepts: 0x followed by 40 hexadecimal characters (Arbitrum).

What happens if my DOT deposit is late or the swap expires?

There are two separate deadlines. The quote itself is held for 90 seconds — that is how long you have to accept the price and create the swap. Once the swap exists you get a separate funding window, shown on your swap page, to send the DOT. If your deposit arrives after that window closes, the status page shows Expired and the swap moves to Review required; it is then completed at the current rate or refunded to your refund address. Nothing is lost by being late — a late deposit just needs review before it is processed.

Can I swap ARB back to DOT?

Yes — every pair works in both directions. The ARB to DOT page is linked below.
