TestNet Outage: Update to v1.2.1


On June 15 at 9:00am PDT, we will start the process of updating MobileCoin’s TestNet to v1.2.1.

TestNet servers will be temporarily down during the upgrade process. Upon update, your TestNet client binaries should continue to work (as they are currently verifying with MrSigner so as not to require an update for every consensus deploy).

Please join us in testing, and as always, let us know if you have any issues.

On June 23, we will enable new blockchain features under v1.2.1 in TestNet. These features will require updating clients in order to properly interact with TestNet.

If you are using TestNet, please upgrade your client code to the following versions (or newer) by June 22, 2022:

  • mobilcoind: v1.2.1
  • full service: v1.9.0
  • android-sdk: v1.2.1
  • MobileCoin-Swift: v1.2.0
