Shimmer Testnet API Service Degradation

API services in the testnet are experiencing issues. The network remains operational and the Mainnet and Shimmer network are unaffected.

March 7th 2023 - 09:15

We have identified an issue in the testnet and are working on a fix.

March 7th 2023 - 12:30

Due to a bug in our core libraries a transaction was issued on the Public Testnet which should have been syntactically invalid. While this did not cause a network crash it caused disruptions in our Public Testnet API endpoints, specifically our indexers. In order to alleviate the problem we have deployed Hornet v2.0.0-rc.5 onto the Shimmer network and Public Testnet. Note: the Shimmer network did not encounter such invalid transaction and has been running without any problems.

We recommend node operators to upgrade to Hornet v2.0.0-rc.5 as otherwise the node will desync if not updated. Additionally, we changed the network id of the Public Testnet to testnet-1, therefore node operators on the Public Testnet need to adjust their config, delete the existing database and snapshots and boot up Hornet v2.0.0-rc.5 with this adjusted global snapshot Note that the binary and deb packages have been removed from the Hornet releases as we recommend to use the Docker setup.
