VISION We are a team of seasoned experts in cryptography, network and cloud security.

Born as Commonwealth Crypto Inc, we're proud to present Arwen.

The technology of blockchain has incredible implications for value storage, personal agency, asset ownership, and so much more. As the global community of traditional financial institutions and blockchain developers continue to build a new financial ecosystem, we saw an opportunity to solve one of the biggest roadblocks to large-scale cryptocurrency adoption.

Individual and institutional traders continue to fear loss of their coins due to exchange hacks. We believe that the ideal state of crypto trading combines the best elements of centralization and decentralization. Centralized exchanges are currently the best source of market liquidity and volume, where decentralized exchanges provide superior security and custodianship. Arwen eliminates the risk of losing your cryptocurrency on centralized exchange hack by providing a decentralized security layer.

Using the blockchain itself as the security agent, Arwen aims to be the most secure standard of trading as a technology built for centralized cryptocurrency exchanges. Our protocol and system has been developed by a team with over a decade of expertise in cryptographic standards and network security.

Much of the value of blockchain-based cryptocurrencies derives from the absence of a single trusted party. Why then is a single trusted party still required when trading one cryptocurrency for another? Don’t give up your keys or coins in order to access the market. With Arwen, you’ll trade with confidence and peace of mind, knowing you don’t have to sacrifice security for liquidity.

We’re building better crypto trading infrastructure and have the best team in the business. If you’re excited about our mission, check out our job openings below or reach out!
