Why people swap ARB to DOT.
Maximizing DeFi opportunities. Arbitrum is the leading Ethereum Layer-2 solution, offering near-instant confirmation times and full EVM compatibility. Swapping ARB to DOT allows users to tap into Polkadot’s robust ecosystem of cross-chain bridges and parachains, enhancing their DeFi journey.
Interoperability benefits. Polkadot is designed as the 'internet of blockchains,' allowing seamless communication between different networks. By swapping ARB to DOT, users can participate in the broader Polkadot network, benefiting from cross-chain bridges and governance features.
Stylus smart contracts. Arbitrum’s Stylus allows developers to build smart contracts using Rust/C++, providing unparalleled security and performance. This makes Arbitrum particularly attractive for complex DeFi applications, such as on-chain perpetual futures trading via GMX.
Decentralized governance. Polkadot’s OpenGov system enables decentralized decision-making, giving community members a voice in the network’s future. By swapping ARB to DOT, users gain access to this unique governance model, fostering a more democratic blockchain environment.

常见问题。
01 What's the current ARB to DOT exchange rate?
Right now 1 ARB equals about DOT. The rate updates every 60 seconds on this page. The exact amount you'll receive is locked at the moment your ARB arrives at the deposit address.
02 How long does an ARB to DOT swap take?
Average end-to-end time is about 5 minutes. The main variable is Arbitrum network confirmation speed — typically 0.25 seconds on L2. You can track progress in real time on the swap page.
03 Which ARB networks are supported?
SwapHub supports ARB on Arbitrum One (main) and Arbitrum Nova (gaming/social). Pick whichever network your source wallet holds ARB on — the cheapest option is highlighted automatically.
04 What is the minimum and maximum amount?
Minimums vary by pair and are shown before you confirm — typically around $10–$20 equivalent. There's no hard maximum — larger orders may be split across providers automatically for the best rate.
05 Float rate vs Fixed rate — which should I pick?
Float gives you the best available rate at the moment your deposit arrives (usually a slightly better number, subject to movement). Fixed locks the rate when you create the order, costing about 0.4% extra — worth it for large amounts or when the market is moving fast.
06 Is there a fee on top of the exchange rate?
SwapHub charges no extra fee on top of the displayed rate — our margin is already included in what you see. You'll also pay the network fee for DOT and gas on your chosen ARB network.
07 What happens if I send the wrong amount?
If you send less than the minimum, the order pauses and you can add a top-up. If you send more than the estimate, you'll automatically receive the extra DOT at the locked rate. Sending a different coin to the ARB address is recoverable but requires contacting support.
08 Can I swap ARB to DOT inside Telegram?
Yes. @swapHUB_com_bot opens a Telegram Mini App with the same flow, same rates, same providers. Convenient for mobile users who already live in Telegram.
09 Is SwapHub regulated? Where is it based?
SwapHub operates as a non-custodial interface that routes orders across multiple licensed exchange providers. We don't custody funds, so the regulatory model is closer to an aggregator than an exchange. For jurisdiction-specific questions, see the Terms.
10 What networks can I use for ARB to DOT swaps on SwapHub?
For ARB to DOT swaps on SwapHub, you can use ARB from the Arbitrum One network or Arbitrum Nova network, and DOT from the Polkadot Relay Chain or any of its Parachains such as Acala, Moonbeam, Astar, and more.
