According to Foresight News, BNB Chain announced that the opBNB testnet Fermat hard fork is scheduled to be activated at block height 12113000, which is expected to occur between 14:00 and 14:15 Beijing time on November 3, 2023. 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 achieve interoperability between opBNB and Greenfield. In addition, the stable L1 Gas price will make it easier for developers to estimate their transaction costs.
