The Arwen Trading Protocols

The Arwen Trading Protocols are layer-two blockchain protocols for 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 where the agent of escrow is the blockchain itself. Each 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 even with the “lowest common denominator” of blockchains—namely Bitcoin-derived coins without SegWit support. As a result, Arwen supports essentially all “Bitcoin-derived” coins e.g., BTC, LTC, BCH, ZEC, as well as Ethereum. Our protocols support Limit and RFQ order types, we implemented our RFQ protocol and it is available for use at arwen.io.
