Thank you for always using PlayMining.

Today, we announced a new whitepaper, “DEP Protocol, ” which will determine the future of DEP (DEAPcoin).

In conjunction with this, to maximize the value of DEP and evolve into a global-standard public chain project, we will fundamentally revamp the PlayMining platform’s service structure (complete transition to Web3) .

Due to this transition, the PlayMining wallet functions currently provided by the platform, as well as the handling of NFTs on the PlayMining platform, will be discontinued.

Therefore, users will need to transfer their assets (DEAPcoin, NFTs) to an external wallet (such as MetaMask).

This announcement includes requests that will require effort from our users. However, this is an unavoidable and positive step for DEP to be reborn as an “asset usable worldwide.”

Below, we will explain its objectives and specific change procedures.

 

1. New “DEP Protocol” Concept and Objectives of the System Transition

Why change now?

Until now, PlayMining has operated primarily with its proprietary platform, prioritizing ease of use. However, to maximize access to the DeFi (Decentralized Finance) market, estimated to be worth 26 trillion JPY, to foster the emergence of autonomous decentralized services and businesses, and to enhance the value of DEP, we need to improve the current “closed environment.”

Our vision for the future: Towards DEP Chain and a Decentralized Ecosystem with Infinite Possibilities

As outlined in the whitepaper released today, we will launch our own “DEP Chain” utilizing Avalanche technology. Here, a robust economic sphere will be built where DEP is consumed as gas fees and generates yields through staking.

For everyone to fully benefit from this new economic sphere, DEP must be placed in an environment where it can freely connect to various decentralized services. To improve DEP’s price, we have decided on a bold system transition.

 

2. Changes in Service Structure (Discontinuation and Continuation of Functions)

Towards the operation of the “DEP Protocol,” the wallet functions and NFT marketplace functions on the current PlayMining platform will be gradually discontinued according to the following schedule and migrated to a standard environment on a public chain.

Main Changes:

•Discontinuation of PlayMining Wallet Function
The wallet functions on the PlayMining platform will be discontinued, and users will directly manage their DEP and NFTs using their own external wallets (such as MetaMask). Along with this, DEP deposit/withdrawal functions and NFT bridge functions will also be gradually suspended.

•Discontinuation of PlayMining NFT (Marketplace)
With the discontinuation of NFT handling (including viewing and management functions) on the platform, the “PlayMining NFT” marketplace service will be terminated. The vision is that transactions will be possible on external marketplaces such as OpenSea in the future.

•Evolutionary Resolution of PlayMiner Rank System
With the discontinuation of wallet functions, the current rank system (Apprentice, Auctioneer, Connoisseur) will be abolished.
⚪︎Personal information (phone number, identity verification documents, etc.) provided for rank updates will be responsibly discarded according to our company’s regulations after the migration is complete.
⚪︎As a new alternative system, the “Agent System,” which allows users to receive benefits based on their DEP holdings by connecting their wallet, is scheduled to be implemented on the DEA official website by January 2026.

•[Continued] PlayMining ID (PMID)
Login functions to various contents using PlayMining ID (PMID) and new account creation functions will continue to be available.

6. Message from Naoto Yoshida and Kozo Yamada of DEA Inc.

Again, we apologize for any inconvenience this change may cause to our users.

However, this is by no means a “reduction in service.”
This is a “departure” for DEP to compete globally as a “public asset” that no one can manage, but everyone can trust, just like Bitcoin and Ethereum.

The “DEP Protocol” announced today is designed with a model where DEP is continuously “consumed (burned)” in the real economy by incorporating AI data demand. And your DEP, transferred to external wallets, will be able to directly benefit from network growth through staking on the new chain, among other things.

We ask for your cooperation in switching to this new vessel, believing in the significant leap of DEP beyond the temporary pain (the effort of migration).

Please look forward to “Chapter 2” of DEP.

DEA Inc.
