Just to confirm, to prevent:

  • 1 voting new priorityFee?
  • 2 Using EIP1559 for the transactions?

If we have 1 but not 2, isn't some possible issue of using eip1559 while priorityFee is not updated?

checked bool means we've already determined whether this chain supports priority fee. from the second time and on it will directly use supported bool

// temporary disable EIP-1559

supported: false,
checked: true,
},
}
