BNB Chain has announced that a glitch in MetaMask, a popular Ethereum wallet, has been fixed. The glitch caused MetaMask to overestimate gas fees for opBNB, an optimistic rollup layer-2 of Ethereum. This led many users to pay higher fees than necessary. BNB Chain worked with the MetaMask team to resolve the issue, and now the wallet accurately displays opBNB’s fees. The team also clarified that opBNB’s fees can be much lower than other L1 and L2 networks. Users can now check opBNB’s fees by switching to the network within MetaMask and attempting a transaction. The development of opBNB was done using the OP Stack framework, which aims to create a “Superchain” of interconnected blockchain networks.
