What is ×CHAINge?

Wallet for crypto assets

  • Store any existing cryptocurrency or token in the most user-friendly wallet. It's so easy to use, even your grandparents will handle it with ease.

Service with OTC peer-to-peer transactions

  • Exchange tokens on-chain and cross-chain over the counter (OTC) with no limits. We won’t even charge you for that!
  • Trade physical goods in exchange for ETH or any other ERC-20 token.
  • Build complex Smart Contracts for scheduled or conditional payments.
  • Create crypto-derivatives – options, forwards and letters of credits for physical goods; borrow and lend digital money. ×CHAINge makes it as easy as it is in the offline world.
  • Choose one of the many available independent crowd-rated arbiters and notaries to guard your token or a physical goods deal or become one and get paid for your services.

Platform for safe and rapid exchange

  • Experience the speed of centralized exchanges and the security of decentralized exchanges all on one platform, powered by a network of autonomous transaction clearing nodes called Matcher nodes.
  • Start your own Matcher node to support the network and get XCH token rewards.

Completely decentralized exchange network

  • Feel safe and anonymous, as all deals are processed by a completely decentralized Ariadna Network, not subject to external regulations and single-point-of-failure risks.


Intuitively simple

The UI of our wallet and marketplace is one of the simplest and user-friendly you’ve ever seen in the cryptoworld. We are inspired by the best mobile banking applications and services, so that you feel familiar working with ×CHAINge.


Arbiters, Notaries and Matchers insure your deals with their own security deposits. The Proof-of-Snitch protocol, which is the foundation of Ariadna Network, ensures that neither other users nor Matchers can cheat and take over your assets.


Our specially designed Matcher nodes are capable of providing transaction speeds comparable to centralized exchanges. We know how frustrating it is to just sit there and wait so at ×CHAINge we will make sure to keep transaction clearing times to a minimum.


×CHAINge does not charge you for operations. You only pay the standard Ethereum transaction fee and fees charged by Mediators and Matchers, who set the prices themselves which ensures a fair competition and eventually the lowest prices.


There is no need to sign up to the system. ×CHAINge does not ask you for any personal data because we believe that your opportunity to manage your own assets and trade should not be affected by who you are. On the internet nobody knows you're a dog.


The foundation of our solution, the Ariadna Network, is a decentralized exchange and transaction clearing system which eliminates possible cheating and single-point-of-failure risks and prevents the system from external regulation.

The interface of ×CHAINge will be intuitive and entirely familiar to anyone who used an online banking app before.
