Polis Core

We are delighted to announce the release of Polis Core v1.5.0. This version introduces security updates over the Proof-of-Stake protocol and the first release for the deterministic masternode switch.

You can download the release here: https://github.com/polispay/polis/releases/tag/v1.5.0

The update is MANDATORY, and the chain will fork on October 10. After the fork, the minimum amount of a single UTXO to stake will be 100 Polis.



For non-experienced users: You can use the CryptoShark script:

rm polis_update.sh* 
wget -q https://raw.githubusercontent.com/cryptosharks131/Polis/1.5.0/polis_update.sh

For PolisNodes users: Wallets are not yet updated and will be updated in the coming days. Users will be notified by email and on social media. Once we notify you, users must update their local wallets and restart their masternodes.

For experienced users: This update introduces BLS signatures to the masternode signature verification, you will need to add another private key to the polis.conf on the VPS, the signature name is masternodeblsprivkey, and you can generate it using the bls generate command using the console

Polis Core: Masternode Tools

Once this feature is fully developed users will be able to run masternodes from Trezor cold storage. Running masternodes will be extremely safe since funds for the collateral will no longer be kept on a desktop wallet and they will be stored on the Trezor device, either Model One or Model T as they will safe-keep the private keys.

After the fork on October 10 users will be able to run masternodes from Trezor. This feature will work both on Model T and Model One, although users will need to upgrade the firmware of Model One to version 1.8.2.

Disclaimer: This feature is not yet available and will only be available after the fork on October 10.


We recently released a new update, version 7.3.0. The update focused on improving stability, and loading times for coins on the app. To achieve this, the team transferred all of our services to Blockbook (Trezor wallet back-end service), which allowed us to make the user experience much more stable, fluid, and fast.

The update was released with the following patch notes:

— Up to 70% faster loading times for your balance and transaction history queries.

— Instant coin creation for new wallets.

— Improvements in the Voucher UX and process reliability.

— Improved UI in some key areas.

— Bug fixes.

The team has begun to work on expanding our variety of vouchers, which will allow us to offer the best possible options and cater to a broader part of our users.

Any issue related to the vouchers featured should be reported to the support team.

Disclaimer: only download the app from the official Google Play Store, App Store, and the official Github repository

The next release will be focused on implementing Trezor support. The estimated release time for the next update is due in a week; stay tuned for further updates.

PolisPay cards

Regarding the PolisPay cards, there are some updates with the on-going process we would like to share:

— We are still waiting for the Cacao license

— Final documentation for establishing a company in Europe is awaiting paperwork. This will allow us to sign a contract with a card provider company for Europe.

— We are also having some difficulties with the importation of the Union Pay PolisPay cards, as the Mexican authorities have strict laws regarding this subject. We just finished importation related paperwork, we expect for the cards to arrive shortly. Once we have them we will begin the implementation process.

There’s a real possibility that we might be able to integrate the three main card providers: Visa, Mastercard, and Union Pay. Although it is possible we don’t want to take it for granted; we will update the situation.

We were overwhelmed by the amount of support and excitement from our community, so we wanted to take some time to answer some FAQ about the cards:

When will the card be released?

At the moment there is no exact release date, although the release is scheduled for the Q4. Stay tuned for further updates!

If I already had a PolisPay card, will I be able to use it?

If you had the PolisPay card issued by MasterCard, you wouldn’t be able to use your card as the providers have changed. Union Pay will provide new cards.

Will the beta testers from the past card remain the same, or will they change?

If you were a beta tester from the previous card, you would remain a beta tester for the new card.

I’m interested in being a beta tester. What can I do?

If you would like to apply for the new card, please fill out this form:

Open-source initiative

The Polis Core team has realized the necessity of making the entire Polis ecosystem open-sourced, we embrace and celebrate principles of open exchange, collaborative participation, transparency, and community-oriented development.

We believe that by making the entire Polis environment open-source and accessible, we will be able to build upon each other’s ideas and discoveries, solve problems together, promote collaboration, and thus become more secure and stable.

That is why the Polis Core team is starting the process of redoing some services and making it publicly available. In the foreseeable future, we hope to have the PolisPay open for everybody so the community can also contribute to it. The plan of work would change, but the development channel on Discord would still be used for updating the community on PolisPay related modifications.

The Polis Core team has begun the process of making the entire Polis ecosystem open-sourced by making available: our rates services, our hot wallet connections and our connection with the database. You can go check them out on the following links:

Rates services (Obol):


Connection with hot wallets (Plutus):


Connection with the database (Hestia):
