A “glitch” in MetaMask that resulted in higher-than-accurate opBNB gas fees has been successfully resolved, as confirmed by BNB Smart Chain. This issue could have led users to overpay for transactions, as many follow the default recommended fee displayed in their wallets.
OpBNB, which functions as an optimistic rollup layer 2 solution for Ethereum, was launched on September 13 and was developed by the team behind BNB Smart Chain.
The problem arose from MetaMask’s approach to calculating recommended gas prices. It was using an average of fees across various networks to determine the default minimum recommendation price for gas. While this was a suitable strategy for other layer 2 (L2) networks, it didn’t align with opBNB. OpBNB often offers significantly lower fees compared to other L1 and L2 networks, rendering the estimation inaccurate.
To address this issue, BNB Smart Chain reached out to the MetaMask team, which cooperated by agreeing to update its algorithm. As a result, MetaMask now correctly displays opBNB’s network fees.
Users can now verify the fees for each network by switching to opBNB within their MetaMask wallet and attempting a transaction. This action should demonstrate that opBNB frequently offers more competitive fees than its competitors.
OpBNB was built using the OP Stack, a modular framework designed for creating interoperable blockchain networks. Developed by the OP Labs team, the OP Stack aims to establish a “Superchain” comprising multiple interconnected blockchain networks, although it faces competition from Polygon’s “Supernets,” which pursue a similar goal.
