Note

We offer the ability to override our fee estimates with the feeOverride parameters. This param does not include preVerificationGas (PVG) . The method will always increase the estimated PVG by 5% to give the UO a better chance to mine if the L1 /L2 fee ratio changes. If you would like to modify this value, its recommended you use alchemy_requestPaymasterAndData instead.
