A “glitch” in MetaMask that caused it to overestimate opBNB gas fees has now been fixed, according to a social media post from BNB Chain. Many users pay the default recommended fee displayed in their wallets, so a misestimation can cause users to overpay.
opBNB is an optimistic rollup layer-2 of . It was launched on Sept. 13 and was developed by the team that created BNB Chain. According to the team, they discovered recently that “Metamask had set a default minimum recommendation price for gas based on the average of all networks.” This was a reasonable policy for other L2 networks, the team said, but it “didn’t quite align with opBNB.” The team claimed that opBNB fees “can be much lower than other L1 and L2 networks,” making the estimation inaccurate.
