On June 20th, the cross-chain bridge zkBridge will support the hard fork of BNB Chain Haber and Tycho. The impact of this upgrade on zkBridge includes: the introduction of new fields in the block header, such as WithdrawalsHash, which causes changes to the calculation logic of BlockHash (modifying the logic related to BlockHash verification in the update circuit to include the newly added fields in the BlockHash calculation); the introduction of a new transaction type BlobTxType, which affects the calculation of the transaction receiptsRoot (this change has no impact on the zkBridge contract).
