How to exchange DOT for ATOM safely and at a good rate
To switch from Polkadot to Cosmos Hub you don’t need to sell for dollars first and then buy again. ROVEN exchange does it in one step: one order, one rate, one payout.
Polkadot (DOT) is Gavin Wood’s network that unites many parachain blockchains under shared security. Cosmos (ATOM) is the coin of the Cosmos Hub, the centre of an ecosystem of interconnected blockchains.
Why swap DOT for ATOM
Coins serve different purposes, and sometimes holding ATOM makes more sense — for faster transfers, staking or the Cosmos Hub ecosystem. With ATOM you get access to the apps, staking and tokens of the Cosmos Hub network.
Networks and addresses
| You send DOT | You receive ATOM | |
|---|---|---|
| Network | Polkadot | Cosmos Hub |
| Address | starts with “1” | “cosmos1…” |
| Network speed | a block comes every 6 seconds | a block comes every 6 seconds |
| Memo / tag | Not needed | Only for an exchange address |
What to watch out for
- Staked DOT doesn’t unlock instantly — send only your free balance.
- The address must start with “cosmos1”, not the prefix of another Cosmos network.
- If you’re receiving ATOM to an exchange address, be sure to enter that exchange’s memo.
- Send the exact amount from the order and do it within 30 minutes, while the locked rate is valid.
How long the swap takes
Swap speed depends on both networks. On Polkadot, a block comes every 6 seconds; on Cosmos Hub, a block comes every 6 seconds. The whole DOT to ATOM swap usually takes 5 to 30 minutes once your transfer is confirmed.
The current rate is 1 DOT = 0.658784 ATOM and the minimum amount is 20 DOT. Create an order in the form above, and ROVEN exchange will send swap updates by email or Telegram.
