BNB Chain has announced the implementation of four hardforks on the opBNB testnet, scheduled between 6AM and 6:30AM UTC, on May 15th. These forthcoming changes will significantly reduce the gas cost on opBNB, by an approximate factor of 10.

In preparation for these changes, all opBNB testnet nodes need to be updated to the latest version before the scheduled date and time. The upgrade prior to 6AM UTC, May 15th, is a crucial step to prepare for the hardforks and to ensure a smooth transition.
