1  Alternate cryptocurrencies / Altcoin Discussion / RPC Error with Payload on: March 03, 2018, 12:00:32 PM
Hi all, I am trying to transfer Polyswarm (NCT) to tokens from my MetaMask (via MEW) to my Ledger Nano S but the transactions has failed.  The error message is 'RPC Error with Payload' and some code followed by 'Intrinsic Gas too Low'.  I varied the gas from 200000 to 250000 with no difference - any idea what the issue could be?  It also says 'Error in TXN' reverted on MEW.  Thankfully my tokens are still showing in MetaMask so not lost!  Any help would be gratefully received.

Hi all, I have ordered a Ledger Nano S because it can store about 50% of the altcoins I am looking to purchase.  However, in terms of the other 50%, can anyone advise the safest way to cold store them, ideally with another type of hardware device?  How easy would it be to use an old laptop that I have noting that it is about 10 years old...! Specifically, the altcoins I am referring to are as follows:


Any help or a steer would be much appreciated.
