Coin compensation service that ensures peace of mind even in the unlikely event of PoR (Proof of Reserve) being realized.

  • PRODUCT

Shirushi Corporation, in collaboration with its overseas entity SRS Inc. of the Shirushi Group, has prioritized the protection of customer assets and launched a robust coin replenishment service known as PoR (Proof of Reserve). In the event of an unforeseen situation affecting the Shirushi Group, we will redeem customer assets from the mining pool. In such cases, any shortfall in the redemption amount will be supplemented from the segregated storage addresses held by our group. Additionally, the coin balance existing in the segregated storage addresses can be verified at any time by anyone through blockchain explorers or our service site. 【Response Flow of This System】 If a shortfall occurs when SRS Inc. redeems from the mining pool, our group will provide instructions to the bankruptcy trustee appointed by the court to supplement the shortfall to customers from the segregated storage addresses holding Shirushi Coins (hereinafter referred to as SISC). The bankruptcy trustee will execute the necessary procedures to ensure that the SISC stored in the segregated storage addresses is sent to customers who have experienced a shortfall, based on instructions from Shirushi Corporation.

The Shirusu coin is listed on the major cryptocurrency exchange "BitMart."

  • PRODUCT

SRS Inc. (Headquarters: Bahamas), a group company of Shirushi Co., Ltd., has listed its unique token "Shirushi Coin" on the major cryptocurrency exchange "BitMart." Shirushi Coin has been traded on overseas DEXs for two years and has continued to rise in price until now. This is the first listing on a CEX, and a more robust trend is expected than ever before. The mechanism behind this price increase is due to our patented technology. We utilize the sales of our products and services, including our mining machine "Web3 Maker," to buy back Shirushi Coin. Therefore, the more units sold, the more the price of Shirushi Coin increases. Due to this patented technology, the price of Shirushi Coin has risen by up to 33.3 times, making it a coin with promising potential for the future.
