A "bug" in MetaMask that caused overestimate opBNB gas fees have now been fixed, according to a BNB Chain post on social media. Many users pay the default recommended rate displayed on their wallets, so a wrong estimate can cause users to overpay.
Together with our friends from @MetaMaskWe resolved an issue that made opBNB gas rates appear to be unusually high.
Now you can enjoy the true benefits of opBNB: fast, cheap and secure transactions. This is how it happened: [1/7]

opBNB is a optimistic cumulative layer-2 of Ethereum. He was released on September 13 and was developed by the team that created BNB Chain. According to the team, they recently discovered that "Metamask had set a default recommended minimum price for gas based on the average of all networks." This was a reasonable policy for other L2 networks, the team said, but "didn't quite align with opBNB." The team stated that opBNB's fees "may be much lower than other L1 and L2 networks," making the estimate inaccurate.

To resolve this issue, BNB Chain contacted the MetaMask team, who were “extremely helpful and agreed to update their algorithm.” As a result, the wallet now accurately displays network fees.
According to the BNB Chain team, users can now check each network's fees by switching to opBNB from MetaMask and attempting to make a transaction, which they say will show that the network often has lower fees than competitors.
opBNB was developed using OP Stack, a modular framework that can be used to create interoperable blockchain networks. OP Stack was developed by the OP Labs team, which is trying to create a "Superchain" composed of multiple interconnected blockchain networks. The Superchain faces competition from Polygon's "Supernets", which try to achieve a similar goal.
