Dear Cypherium Community,

We are writing to you today with exciting news. This is perhaps the most exciting moment in the history of our project. The moment our team, our developers, and our supporters have been anticipating since Cypherium’s inception in 2016: our full mainnet deployment is finally here.

Our mainnet will be launching on October 31, 2020.

Tokens purchased in our pre-sale and public sale will be distributed according to our vesting schedule — please visit for more information. Tokens will be distributed to the CPH addresses that you’ve created at and added to your pre-sale and public sale profiles.

Tokens for pre-sale participants will be distributed on October 31, 2020. Tokens for public sale participants will be distributed shortly after our vendor, TokenSoft, completes their audit of all payments received when the Public Sale closes on October 31, 2020 at 9 PM Pacific Time (PT) — we will communicate the public sale distribution date within the next few days.

To access your tokens upon our mainnet distribution, you will need to download the Cypherium CPH Wallet App on your mobile device via the following links:

Android —

Apple —

For those who do not have a mobile device, don’t worry, additional functionality will be added to our web wallet shortly. Once you have downloaded the wallet, you have to import your specific address and balance by entering your mnemonic phrase that you created previously. You will not be able to transfer tokens at mainnet launch. This will happen when the Cypherium mainnet is fully integrated with our exchange partners as this is a requirement by the exchanges.

To prepare for mainnet launch, we ask that you download these wallets now and test that you can recover/import your CPH wallet address.

We would like to advise the community that mining will only be available on our network once the developers determine that the mainnet is stable. The current mainnet will operate with 21 validator nodes running on the Microsoft Azure platform. As we monitor the health of the network, we will be removing the team-owned nodes gradually within the next 3–6 months, as determined by our engineers and advisors. As we wean off of team-owned nodes, we will begin to accept external nodes, operated by the community at large.

We are extremely excited and proud to bring you our public mainnet. It is the culmination not only of our efforts as a team but also of your constant support as a community. We’re thrilled to be able to take this next step with all of you.
