atomic swap exchange

Swap.Online is a revolutionary crypto over-the-counter marketplace delivering the services of the instant BTC ⇔ ERC-20 and ERC-20 ⇔ ERC-20 exchange. It is based on the principles of real decentralization as no component (e.g. plug-ins, orderbooks etc.) serves as the center or middleman. This story is about buyer and seller only: we don’t store your keys, coins or data. Our exchange uses the Atomic Swaps technology, so you don’t need to use special software or even somehow tune your browser.


Decentralization: mantra or solution?


Since the quantity of crypto frauds and thefts grew rapidly (see figure) as well as the damage caused by them, the decentralized exchanges or DEXs now seem to be the most significant trend in crypto world: the DEXs doesn’t store the users’ crypto. Inspired by that fact, some services use the terms of decentralization without being decentralized indeed. They position themselves as the ‘hybrid’, ‘semi-decentralized’, ‘demi-decentralized’, ‘with critical infrastructure centralized only’ etc. being still decentralized in general.

We dealt with the issue our way.


Swap.Online is fully decentralized without any single component stored on or operated by centralized means. Our swaps are conducted directly in browsers of traders with no keys or money send to us or stored via our technical capacities.

Also we are higher than bulk majority of DEXs in several respects: we support BTC, we stand for the KYC/AML neutrality, our deals are safer and faster because of IPFS and Atomic Swaps technologies implementation. Written on JavaScript, our core is able to be implemented even in projects without JS via the REST API.

So, it’s the time to see it for yourself.
