Hi hi, great start on this! 🤩 The examples are not yet working (this is likely partly AI generated?), so the examples CI is misleading, showing green even on failed runs, see #4016 (discovered it here along, actually great side effect, totally unfortunate otherwise for our releases since this might hide some bugs 🙏).

So, examples are using e.g. VM.create(), this API does not exist any more. Can you have a closer look and make sure that the examples are compatible and run with latest master?

Hi @avdheshcharjan! Thanks a lot for tacking this! Just a quick headsup that we have move some 7702-related helpers (e.g. authorizationLists) into the util package rather than the tx one in this PR: #4032 . This will allow more flexibility for future usage and fits our monorepo architecture better.
