How AtomicDEX Is Different From Other DEXs

  1. Many DEXs in the blockchain space today aren’t genuinely non-custodial since user funds placed in liquidity pools are constantly exposed to impermanent loss, rugpulls, and vampire attacks. AtomicDEX, in contrast, avoids these issues by using decentralized P2P order books.
  2. Unlike most DEXs that exist today, AtomicDEX doesn’t limit trading to a single blockchain protocol. AtomicDEX offers the widest cross-chain and cross-protocol support in the entire blockchain space. It’s easy to trade BTC, ETH, all ERC-20 tokens, KMD, and hundreds of other digital assets natively from dozens of blockchains — no proxy tokens required.
  3. Atomic swaps are designed such that the swap takes place and both traders receive the funds they desire, or nothing happens at all and both traders retain the funds they started with (minus a very small transaction fee for the “order-taker”). Atomic swaps make digital asset trading as secure as it can possibly be.

Frequently Asked Questions

angle-right angle-down Do you store my private keys?

No! AtomicDEX is non-custodial. We never store any sensitive data, including your Bitcoin private key, private key for any other cryptocurrencies, seed phrases, or PIN. This data is only stored on the user’s device and never leaves it. You are in full control of your assets.

angle-right angle-down How is trading on AtomicDEX different from trading on other DEXs?

Other DEXs generally only allow you to trade assets that are based on a single blockchain network, use proxy tokens, and only allow placing a single order with the same funds. AtomicDEX enables you to natively trade across two different blockchain networks without proxy tokens. You can also place multiple orders with the same funds. For example, you can sell 0.1 BTC for KMD, QTUM, or VRSC — the first order that fills automatically cancels all other orders.

angle-right angle-down How long does each atomic swap take?

Several factors determine the processing time for each swap. The block time of the traded assets depends on each network (Bitcoin typically being the slowest) Additionally, the user can customize security preferences. For example, you can ask AtomicDEX to consider a KMD transaction as final after just 3 confirmations which makes the swap time shorter compared to waiting for a notarization.

angle-right angle-down Do I need to be online for the duration of the swap?

Yes. You must remain connected to the internet and have your app running to successfully complete each atomic swap (very short breaks in connectivity are usually fine). Otherwise, there is risk of trade cancellation if you are a maker, and risk of loss of funds if you are a taker. The atomic swap protocol requires both participants to stay online and monitor the involved blockchains for the process to stay atomic.

angle-right angle-down How are the fees on AtomicDEX calculated?

There are two fee categories to consider when trading on AtomicDEX. AtomicDEX charges approximately 0.13% (1/777 of trading volume but not lower than 0.0001) as the trading fee for taker orders, and maker orders have zero fees. Both makers and takers will need to pay normal network fees to the involved blockchains when making atomic swap transactions. Network fees can vary greatly depending on your selected trading pair.

angle-right angle-down Do you provide user support?

Yes! AtomicDEX offers support through Komodo Discord. The team and the community are always happy to help!
