bind TransactOpts

[saman-pasha]

In accounts/abi/bind/base.go #374

	if opts.GasPrice != nil {
		rawTx, err = c.createLegacyTx(opts, contract, input)
	} else if opts.GasFeeCap != nil && opts.GasTipCap != nil {
		rawTx, err = c.createDynamicTx(opts, contract, input, nil)
	} else {
		// Only query for basefee if gasPrice not specified
		if head, errHead := c.transactor.HeaderByNumber(ensureContext(opts.Context), nil); errHead != nil {
			return nil, errHead
		} else if head.BaseFee != nil {
			rawTx, err = c.createDynamicTx(opts, contract, input, head)
		} else {
			// Chain is not London ready -> use legacy transaction
			rawTx, err = c.createLegacyTx(opts, contract, input)
		}
	}

I added another else if for when both GasFeeCap and GasTipCap are specified and no need to retrieve head

Cool. If you want up upstream this change, please open a pull request instead of filing a ticket. I'm going to go ahead and close this one, since there's not any actual bug that needs fixing.
