Golden Finance reported that BNBChain announced that the fermat hard fork of the opBNB test network is planned to be activated at block height 12113000, which is expected to occur from 14:00 to 14:15 on November 3, 2023, Beijing time. Developers should upgrade to opNode v0.2.0 and opGeth v0.2.0 before the hard fork. The new precompiled contracts in this hard fork will enable interoperability between opBNB and Greenfield. In addition, the stable L1Gas price will make it easier for developers to estimate their transaction costs.
