Announcement of upcoming hard forks on the Cardano network
The Cardano network will soon be transitioning from Shelley to Goguen via two planned hard forks. The hard forks, named Allegra and Mary, will see new releases of updated Cardano components which will impact all exchanges.
Allegra hard fork - 16th December
The first hard fork Allegra is planned to be delivered on the 16th of December 2020.
This will require an upgrade of all core integration components for example cardano-node, cardano-wallet etc.
The core components for the Allegra hard fork are expected to be available the first week of December. Once officially released we will notify you of the appropriate time to upgrade.
Mary hard fork - February 2021
The second hard fork Mary is due to be delivered in the middle of February 2021.
This hard fork will require an upgrade of all core integration components. It will also introduce breaking changes to all Cardano APIs. This will require code changes to your exchange systems to adjust to the new APIs and accommodate the introduction of native tokens.
As with the aforementioned hard fork, we will notify you when the testnet and updated components are available along with more detail on native assets.
We will provide more detailed instructions closer to the time regarding the best upgrade process and also instructions on how to list new native assets.
Note: We strongly recommend all exchanges currently listing ada prepare to upgrade to the version of Cardano that supports Goguen and Smart contracts (when available) to avoid any outage, downtime, or disruption
