MetaMask issue led to inflated opBNB suggested fees: Report

A “glitch” in MetaMask that led to an overestimation of opBNB gas fees has now been resolved, as stated in a social media update from BNB Chain. Many users tend to pay the default recommended fee shown in their wallets, so an inaccurate estimation can result in users overpaying.

Alongside our partners at @MetaMask, we’ve addressed a glitch that made it appear as though opBNB’s gas fees were excessively high.
Now, you can experience the genuine advantages of opBNB: swift, affordable, and secure transactions. Here’s how it unfolded: [1/7]

opBNB is an optimistic rollup layer-2 solution for Ethereum. It was introduced on September 13 and developed by the team behind BNB Chain. The team recently found that “MetaMask had established a default minimum recommended price for gas based on the average across all networks.” This approach was suitable for other L2 networks, they noted, but it “didn’t quite match opBNB.” The team asserted that opBNB fees “can be significantly lower than those of other L1 and L2 networks,” leading to the inaccurate estimation.

To address this issue, BNB Chain reached out to the MetaMask team, who were “extremely cooperative and agreed to modify their algorithm.” Consequently, the wallet now accurately reflects the network’s fees.

According to the BNB Chain team, users can now verify each network’s fees by switching to opBNB within MetaMask and attempting to execute a transaction, which they claim will demonstrate that the network frequently has lower fees than its competitors.

opBNB was created using the OP Stack, a modular framework designed for building interoperable blockchain networks. The OP Stack was developed by the OP Labs team, which aims to establish a “Superchain” consisting of multiple interconnected blockchain networks. The Superchain is in competition with Polygon’s “Supernets,” which seeks to achieve a similar goal.
