Why trade with Arwen

Eliminate Counterparty Risk

Eliminate Counterparty Risk

Centralized exchanges continue to be a target for hackers​, which put your coins at risk​. Arwen​'s new technology combines on-blockchain escrows and off-blockchain atomic swaps, which means you never need to deposit your coins in a centralized exchange’s wallet. ​Trade safely on the exchange with peace of mind. The blockchain itself safeguards your coins.

A Fast, Secure Atomic Swap Protocol

A Fast, Secure Atomic Swap Protocol

There’s no need to compromise on speed or liquidity. Access the liquid markets through a centralized exchange and use Arwen to trade with far greater security. Our layer 2 protocol enables trades using atomic swaps, a cryptographically-secure simultaneous exchange of coins across blockchains. Trades are only visible to you and the exchange, protecting you from front-running and griefing.

Compatible with Any Custody Solution

Compatible with Any Custody Solution

Store your cryptocurrency anywhere — whether a third-party custodian or a desktop, online, mobile, or hardware wallet. Blockchain-based escrows are funded directly from your chosen custody solution. Coins remain secure while you trade and then return to your custody solution when you close out your Arwen escrows.
