The Arwen Trading Protocol is a layer-two blockchain protocol that allows traders to securely trade cryptocurrencies at a centralized exchange, without ceding custody of their coins to the exchange. Before trading begins, traders deposit their coins in an on-blockchain escrow, rather than in the exchange’s wallet. The agent of escrow is the blockchain itself. Each individual trade is backed by the coins locked in escrow. Each trade is fast, because it happens off-blockchain, and secure, because atomic swaps prevent even a hacked exchange from taking custody of a trader’s coins. Arwen is designed to work with all blockchains even Bitcoin -derived coins without SegWit support. As a result, Arwen supports essentially all “Bitcoin-derived” coins, including BTC, Litecoin, Bitcoin Cash, Zcash as well as Ethereum and ERC20 tokens. 
Arwen was founded by Sharon Goldberg and Ethan Heilman. The duo have years of expertise in network security, cryptocurrency , and cryptography.
