Networks and wallets for DOT to ARB
Polkadot Hub (Asset Hub, native DOT)
Check the chain named in the deposit instructions. Native DOT on Polkadot Hub, also called Asset Hub, is held on a different chain from DOT on the Relay Chain, even if the address looks the same.
Arbitrum One (ERC-20 ARB)
Check that the receiving service credits ARB on Arbitrum One specifically. If you plan to send it onward from self-custody, leave some ETH on Arbitrum One for fees.
Check DOT deposit and ARB payout availability separately. The live service needs to accept your source network and offer the destination network that your ARB wallet expects.
How to convert DOT to ARB

- Enter a receiving address on Arbitrum One · ERC-20 ARB and a refund address on Polkadot Hub mainnet · native DOT. Check any destination tag your wallet requires.

How to compare DOT to ARB rates
For a rough pre-fee estimate, multiply the DOT amount by the rate expressed in ARB per DOT. Then compare the actual ARB payout for the same DOT amount and network. Check whether the withdrawal fee comes out of what you send or is charged separately.
Swap Crypto has a $100 minimum. Estimates use market prices before fees. The order page shows the exact send and receive amounts, and your wallet may charge a separate network fee for sending the deposit.
