現實生活中的金錢雖然能透過多次的轉移來增加金流量，但對於轉移過程中的各擁有者都只能發揮一次效用。
以太坊區塊鏈上的虛擬貨幣則不然：虛擬貨幣能夠在被支付到一個服務的同時，為其擁有者創造更多筆效用、更多的收益。
本論文提出將存放在智能合約中的虛擬貨幣投入如 Compound 的去中心化借貸市場賺取存款利息，並能用 Compound 所返還的借據再進一步投入去中心化虛擬貨幣交易所 Curve 賺取部分的手續費。
Compound 的流動性問題能藉由使用此方法所獲得的收益來解決，而我們也就對收益的分配進行討論並和現存的方法進行比較。
本論文以實驗的方式驗證所提出方法的結果正確性及計算實作的成本，並使用工具檢測實作的智能合約的安全性。

Money in real-world scenarios, though can be transferred multiple times to create larger cash flow, it usually serves only one usage for each user.
Cryptocurrency on Ethereum blockchain, however, can be paid to service and generate extra profit for the owner at the same time, which means it can serve multiple usages and its time value is efficiently utilized.
We propose to maximize the time value of cryptocurrency kept in smart contracts by investing it to decentralized money markets of Compound to earn supply interest.
Moreover, we can further invest the receipt we receive from Compound in Curve, a decentralized cryptocurrency exchange, to earn a share of the handling fee.
The liquidity risk of Compound can be mitigated by utilizing the interest generated, and the distribution of the interest generated by the proposed method is compared with an existing approach.
Experiments are conducted to testify the proposed method, estimate the implementation cost and analyze the security of smart contracts implementation.
