† Conditional VIP tiers are excluded from the volume-only estimate. Confirm your account eligibility.

* Omni Spot Swap: 0.9% swap fee plus gas, not an orderbook maker/taker schedule. Confirm availability in the app.

† VIP counts spot volume in full and ordinary USDT perpetual volume at 0.4 times notional. GT discount is only modeled for entry spot.

† VIP uses 14-day volume, estimated from 30-day volume assuming evenly distributed activity. Hyperliquid spot volume counts twice.

Published entry-tier spot rates; volume tiers and native-token discounts can lower these further.

Liquidity and spread

DOT has deep liquidity on the large exchanges, so slippage is small at retail size. Your all in cost is the fee plus the spread, and the spread mostly matters on thinner venues, so weigh both rather than the headline fee alone.

Do not forget the withdrawal fee

DOT withdrawals settle on the Polkadot relay chain, where on-chain fees are modest, but the fixed DOT withdrawal fee still varies by exchange. When you withdraw to self-custody, remember the existential deposit, the small minimum balance an account needs to stay active, since letting a wallet fall below it can remove the account.

FAQ

What is the cheapest exchange to buy Polkadot?

There is no single cheapest venue for DOT. It depends on your monthly volume, maker/taker mix, and any native-token discount. The published fee is usually the main cost on liquid majors. Check your profile in the FeeEdge calculator. DOT is liquid on the majors, so the published fee is usually the main cost; also check your volume tier and any native-token discount.

What is the existential deposit when withdrawing DOT?

It is a small minimum balance the Polkadot network requires to keep an account active. If you withdraw DOT to self-custody, leave at least that amount in the account, because letting the balance fall below it can deactivate the account and remove any remaining dust. Your exchange withdrawal fee is separate from this.
