Using Arwen in Beta

Mar 29, 2019 · 3 min read

We’re excited to announce that Arwen Beta will shortly go live on KuCoin! Arwen allows traders to self-custody coin while trading on a centralized exchange’s orderbook, through the use of on-blockchain escrows and secure cross-chain atomic swaps.

You will soon be able to use Arwen in Beta to trade the LTC-BTC and BCH-BTC pairs on KuCoin’s centralized orderbook. In this blog post, we cover what you can expect when using Arwen while it is in Beta.

Trading amounts are limited

Because Arwen is in Beta, we’ve temporarily limited the amount of coin you can lock in escrow and trade. Currently, each escrow you can open with Arwen is limited about $120 USD worth of coin, and each trade is limited to about $20 USD worth of coin. The number of escrows that may be open at the same time, by a single user, is also limited during this Beta period.

Arwen security road map

We are working hard to enhance security and add features to the current Beta release of Arwen. Below is a list of just some of the security features we’re working on, that will be included in future releases of Arwen.

Arwen Trading Protocol Security Assumptions

The Arwen Trading Protocols ensure that the trader’s coins are safe even if an attacker compromises the exchange, or the Arwen Hub that speaks Arwen on behalf of the exchange. This holds as long as the trader remembers to

1. close her escrows before they expire.

2. come online during the coin recovery period indicated by the Arwen App, in the unlikely event that the exchange improperly aborts one of her trades.

The traders’ coins are safe if she remembers to do items 1 and 2 above. If the user forgets to do items 1 or 2 above, then her coins are at risk only if the exchange is hacked or malicious.
