Fee Flub: MetaMask 'Glitch' Sends opBNB Recommended Fees Soaring

According to the findings of BNB Chain, MetaMask practice of averaging recommended fees across different networks resulted in a significant increase in opBNB recommended costs.

A recent social media post by BNB Chain confirms that MetaMask has resolved the “glitch” responsible for overestimating opBNB gas fees. It is crucial to note that many users rely on the default recommended fee displayed in their wallets. Thus, any miscalculation could result in unintentional overpayments.

Together with our friends at @MetaMask, we've resolved a glitch that made it seem like opBNB's gas fees were unusually high.

Now, you can enjoy the true benefits of opBNB: fast, cheap, and secure transactions. Here's how it happened: 🧵[1/7]

OpBNB, an Ethereum layer-2 solution that utilizes optimistic rollup technology, made its official debut on Sept 13. This project was developed by the same team that created BNB Chain. Recently, the development team discovered an issue regarding the default gas price recommendation in Metamask.

While this policy may work well for most layer-2 networks, it doesn’t align perfectly with opBNB’s unique dynamics. The opBNB team argues that fees on their network are often significantly lower compared to both layer-1 (L1) and other layer-2 (L2) networks, making the gas price estimation inaccurate.

opBNB Unique Approach In The Blockchain Network Landscape

The BNB Chain team addressed the issue by contacting the MetaMask team, who were incredibly cooperative and agreed to revise their algorithm. As a result, the wallet now accurately displays the network fees.

The BNB Chain team has announced that users can now easily assess the fees associated with the each network. By transitioning to opBNB within the MetaMask interface and initiating a transaction, users will have a practical demonstration of how this network’s fees often compare favorably to those of its competitors.

The OP Labs team constructed opBNB using the versatile OP Stack framework, specifically designed for building interconnected blockchain networks. They aim to establish a “Superchain,” a network of blockchain networks. However, they face competition from Polygon’s “Supernets” initiative, which aims to achieve a similar objective.
