Producer letter

2025.10.16

Eureka Entertainment Ltd. (CEO: Takuya Tsuji) operates the blockchain game “CoinMusme Dream Race.” This is a Producer’s Letter from Tsuji.

Introduction

Dear CoinMusme community,
This is Tsuji, the producer of “CoinMusme Dream Race.” Today I would like to inform you about the termination of Facewallet’s service and the consolidation of login methods to the LINE Dapps version.

Impact of Facewallet Service Termination

In September 2025, Facewallet announced the end of its service. Because CoinMusme adopted Facewallet for login and as a linked wallet, the related functions will become unavailable after the service ends.

We investigated alternatives; however, providing a sufficiently stable replacement by Facewallet’s sunset date is difficult. Therefore, we will consolidate login and wallet functions into the LINE Dapps version. We plan to end the use of Facewallet as an in-game function by the end of October.

For NFTs exported to Facewallet: once the service ends, you will no longer be able to import them back into the game. Please make sure to re-import your NFTs into the game before the termination date.

According to the announcement, you can access my.facewallet.xyz until May 4, 2026 to extract your private keys and safely withdraw your assets. Accordingly, MSM tokens will also be retrievable outside the CoinMusme service.

We are unable to respond to inquiries about Facewallet’s termination. Please refer to the following official sources:
