the setDefaults has a lot of logic handling blobs that are passed in the args, and that will become broken if we just change this

We could just call setBlobTxSidecar in CallDefaults. But I'd say it's OK not to support them here.

But setDefaults will set the fee defaults on the latest block.

	if err := args.setFeeDefaults(ctx, b); err != nil {
		return err
	}

And regardless of what order we invoke it, it will use the latest header, and do

	if err := args.setCancunFeeDefaults(ctx, head, b); err != nil {
		return err
	}

SO it will apply cancun checks according to tip, regardless of what the given block is.

How about something like this

// setFeeDefaults fills in default fee values for unspecified tx fields.
func (args *TransactionArgs) setFeeDefaults(ctx context.Context, b Backend) error {
	return setFeeDefaultsUsingThisHeader(b.CurrentHeader())
}
func (args *TransactionArgs) setFeeDefaultsUsingThisHeader(ctx context.Context, b Backend, head *types.Header) error {
	// Sanity check the EIP-4844 fee parameters.

The logic there is to fill in blob proofs and commitments if they were not provided. Those matter only when submitting a tx. Since for a simulation all that can be accessed via evm is blob hashes (which still can be passed in via TransactionArgs).

All in all I think I agree with @jwasinger that CallDefaults is a better validation function to use here. All the methods that involve signing and submitting a tx use setDefaults while all the "simulation" methods use CallDefaults.

return types.AccessList{}, 0, nil, err
}

var to common.Address
if args.To != nil {
to = *args.To
} else {
to = crypto.CreateAddress(args.from(), uint64(*args.Nonce))
}
fmt.Printf("nonce %d\nto %x\n", *args.Nonce, to)
isPostMerge := header.Difficulty.Sign() == 0
// Retrieve the precompiles since they don't need to be added to the access list
precompiles := vm.ActivePrecompiles(b.ChainConfig().Rules(header.Number, isPostMerge, header.Time))
