code, err := public.GetCode(ctx, publicClient, public.GetCodeParameters{
  Address: common.HexToAddress("0xFBA3912Ca04dd458c843e2EE08967fC04f3579c2"),
})
if err != nil {
  log.Fatal(err)
}
if code == nil {
  // No contract at this address (EOA or empty)
}
fmt.Printf("Bytecode length: %d bytes
", len(code))
