英文摘要：
  Price stability has often been cited as a key reason that cryptocurrencies have not gained widespread adoption as a medium of exchange and continue to prove incapable of powering the economy of decentralized applications (DApps) efficiently. Exeum proposes a novel method to provide price stable digital tokens whose values are pegged to real world assets, serving as a bridge between the real world and the decentralized economy.   Pegged tokens issued by Exeum - for example, USDE refers to a stable token issued by the system whose value is pegged to USD - are backed by virtual assets in a virtual asset exchange where users can deposit the base token of the system and take long or short positions. Guaranteeing the stability of the pegged tokens boils down to the problem of maintaining the peg of the virtual assets to real world assets, and the main mechanism used by Exeum is controlling the swap rate of assets. If the swap rate is fully controlled by the system, arbitrageurs can be incentivized enough to restore a broken peg; Exeum distributes statistical arbitrage trading software to decentralize this type of market making activity. The last major component of the system is a central bank equivalent that determines the long term interest rate of the base token, pays interest on the deposit by inflating the supply if necessary, and removes the need for stability fees on pegged tokens, improving their usability.   To the best of our knowledge, Exeum is the first to propose a truly decentralized method for developing a stablecoin that enables 1:1 value conversion between the base token and pegged assets, completely removing the mismatch between supply and demand. In this paper, we will also discuss its applications, such as improving staking based DApp token models, price stable gas fees, pegging to an index of DApp tokens, and performing cross-chain asset transfer of legacy crypto assets.

中文摘要：
价格稳定常常被认为是加密货币没有被广泛采用作为交换媒介的一个关键原因，并且仍然无法有效地推动分散应用程序（DAPP）的经济。Exeum提出了一种新的方法来提供价格稳定的数字代币，其价值与现实世界的资产挂钩，充当现实世界和分散经济之间的桥梁。Exeum发行的挂钩代币（例如，USDE指的是系统发行的价值与美元挂钩的稳定代币）由虚拟资产支持，在虚拟资产交易所中，用户可以存入系统的基本代币并进行多头或空头头寸。保证挂钩代币的稳定性归结为维持虚拟资产与现实世界资产挂钩的问题，Exeum使用的主要机制是控制资产的互换率。如果掉期利率完全由该体系控制，套利者可以得到足够的激励，以恢复破裂的联系汇率制度；Exeum发行统计套利交易软件，以分散此类做市活动。该系统的最后一个主要组成部分是一个中央银行等价物，它确定基本代币的长期利率，在必要时通过扩大供应来支付存款利息，并消除对钉住代币的稳定费的需要，提高其可用性。据我们所知，Exeum是第一个提出一种真正分散的方法来开发stablecoin的公司，该公司能够在基本代币和挂钩资产之间进行1:1的价值转换，完全消除供需不匹配的情况。在本文中，我们还将讨论其应用，如改进基于赌注的DApp代币模型、价格稳定的天然气费用、与DApp代币指数挂钩以及执行遗留加密资产的跨链资产转移。
