Atomic Wallet is a secure, anonymous and decentralized desktop wallet. This means that you maintain control of your private keys, which are encrypted and stored only on your device. It provides its users with full control over their private keys. It is also decentralized, not suffering from issues like being prone to hacking, DDoS attacks, or having any central points of failure.
An atomic swap is a smart contract technology that enables the exchange of one cryptocurrency for another without using centralized intermediaries, such as exchanges.
