Subject: [PATCH] ethclient: support networkID in hex format (#30263)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Some chains’ network IDs use hexadecimal such as Optimism ("0xa" instead
of "10"), so when converting the string to big.Int, we cannot specify
base 10; otherwise, it will encounter errors with hexadecimal network
IDs.
