add tutorial about how to run a localhost testnet (maybe using metamask + remix) #6
Description
I found your project through ethereum.org
-
I tried to use
ethnodeand it is true, it installs easily and it downloads the node and runs it pretty much flawlessly and that is awesome :-) -
I also managed to connect to it via metamask while using remix, but all account addresses that were listed in metamask had 0 ether on it which gave me some headache.
-
After copying one of the addresses shown in metamask when connecting to localhost and running ethnode again with
--allocate=<paste adddress from metamask>it gave 100 ETH to that address.
...but when I tried to deploy a contract or do any kind of transactions, metamask ALWAYS responds with:
MetaMask - RPC Error: Error: Error: [ethjs-rpc] rpc error with payload {"id":9245888516496,"jsonrpc":"2.0","params":["0xf9182b808502e90edd008319a810808...b2b"],"method":"eth_sendRawTransaction"} Error: invalid sender
This might of course be unrelated to ethnode and a metamask or probably geth issue, but still - it would be cool to resolve this and maybe explain how to specifically run ethnode to make it work as a testnet on localhost :-)

Hi @serapath, thanks for trying out ethnode! Sorry for my late reply, for whatever reason I missed the notification for this issue.
I'm able to reproduce the error with MetaMask, right now I'm trying to understand what's happening there. Will update you soon!

TL;DR: when weird stuff happens, restart your browser.
Sounds pretty lame. But I've had problems while developing/testing smart contracts (using MetaMask as a Web3 provider) that were solved just by restarting my browser.
I was able to reproduce your error by restarting
ethnodewith and without--allocate. Every time you restartethnode, it starts with a differentnetworkIdandchainId(they are both initialized by the same random number, seems to be a requirement for EIP155). Having a different networkId allows MetaMask to restart the incremental nonce that is required in a transaction.But I've noticed that MetaMask has issues if you restart your test node (same happens with
ganache-cli). By restarting ethnode with--allocate=0xmyaddressand restarting the browser, I was able to transfer funds from0xmyaddressto another address without any error.Can you please give it a shot and tell me if it works for you?

Hey, sorry, i was a bit busy.
I think I did exactly everything you described but I did not restart my browser after running ethnode.
Actually I'm not completely sure what you are recommending. Restarting the browser would work for me personally, but to recommend this to users of the tool we are building is not a solution that would ever work for us.
Can this be solved differently?
I want to use ethnode so people can use it to develop locally with a little quick testnet.
