Keepin App by Metadium is Here for Mainnet Token Swap: Everything You Need to Know

Dear Metadians,

As you may have noticed, the Metadium team is making headway for major project developments this coming month and next. Our mainnet will be launching on February 28th, four months ahead of its initially scheduled launch date, and we couldn’t be more excited.

Today marks the official launch of our native mobile application Keepin, which is now available for download. In order for a streamlined transition to the mainnet launch, we encourage users to download the Keepin application on their mobile devices (Currently only for Android Google Play Store, but with iOS App Store coming soon). Not only will the Keepin application serve as an access point to the mainnet after the mainnet launches, but it will also streamline the token swap process for users.

To support easy and stable META token to META coin swap, the first available feature is a secure wallet, which is currently limited to only receiving META and registering other wallets holding META via Private Key [at the moment]. Over the course of the next months, we will gradually be issuing updates to the app through added features which will help realize Self-Sovereign Identity; the application won’t need to be redownload as we add more features! In the long-term, Keepin will be an integral part of how users interact with the Metadium mainnet. Stay posted as we reveal more information in the near future on how Keepin will enable users to not only store personal attributes, but also authenticate their identities.

Get Started with Keepin and prepare for the token swap.

Below is a detailed step-by-step guide on how to secure your tokens with Keepin. Please note that we recommend three ways to secure your tokens and prepare for token swap:

  1. Download Keepin, and deposit your tokens into your Keepin META wallet. Once your tokens are in your Keepin META wallet, they will be automatically swapped to META coins when the mainnet launches.
  2. Download Keepin and register Private Key of your wallet holding META through “Add META Wallet” feature provided in Keepin. Once registered they will be automatically swapped to META coins when the mainnet launches.
  3. Deposit your tokens on supporting exchanges before token freeze which is scheduled for 11:59:59 AM KST on February 22, 2019.

The entire process should take less than five minutes.

Android users: Download Keepin mobile app here.

iOS users: Keepin has been submitted to App Store and is currently going through the review process. We will release a separate notice once Keepin is available in App Store.
