Micropayments in Ether over HTTP

Hey, @kds0718 could you please elaborate more on the question? I couldn’t quite understand it.

Sure, with pragma experimental ABIEncoderV2, I can return structs from functions in Solidity. So, I have some functions that do return structs. I also am using a library in which a function receives a struct -- normally from other functions within the contracts, but was curious if there was a way to send a struct as part of a transaction from the Javascript files to test that function individually.

I think unfortunately the web3 part of Truffle does not support this, but figured I'd ask if there were possibly any work arounds

Oh wait, wrong channel, my mistake...!

Hey guys. I'm trying out machinomy locally (with ganache). Got this error when I tried to run the client example code

this.channelsDao.firstById is not a function

Seems like the channel was created just fine

also breaks with latest machinomy.com instructions (using INFURA/rinkeby).

Hey @base0010. Good to know I'm not alone :-)

I cannot go into the machinomy home page:

@ARyaskov

@djKooks it’s OK now. Thanks for the message!

@ARyaskov

@dhl @base0010 Fixed in Machinomy v1.12.5

@ARyaskov Sweeeet!

Hi guys, I'm looking into setting up a local Machinomy test using Ganache and a bunch of fake users.

How can I run a local Machinomy gateway to point to when the Payment method is called ?

Sergey Ukustov

@ukstv

Hmm, maybe it’s a good idea to share a test hub with you. Would that be a more suitable for your case?

Hernán Di Pietro

@hernandp

That would be nice, as I understand that without a local gateway no one will listen to the Ganache-deployed contract events such as OpenChannel.

Hernán Di Pietro

@hernandp

@ukstv Let me know if local testing is possible.

Also, I tried to build in Windows but I couldn't -- not due to machinomy but Sqlite3 build errors. Will try to see that later.

Does anyone have an example of working code for claiming a channel using the latest version (1.12.5 machinomy and 4.1.1 contracts)?

David Leung

@dhl

@ARyaskov Woohoo! Thanks for the update :)

K.I. (Dennis) Jung

@djKooks

@ARyaskov checked! Thanks for help.

Weird bug (240)..., thanks for information! (for gitter community - machinomy/machinomy#240 , fixed by karzak)

Hernán Di Pietro

@hernandp

I made it to work under Ganache-cli :)

Hernán Di Pietro

@hernandp

How Machinomy can work with a Gateway different from machinomy' sample one?

Hernán Di Pietro

@hernandp

e.g: over ganache or Kovan ?

Kevin Davis

@karzak

@hernandp How did you get the contracts the deploy to Ganache? When I run truffle migrate nothing happens. Is this because the migration files are written in typescript?

Hernán Di Pietro

@hernandp

You are right, @karzak , doing truffle migrate with yarn did not work. I simply deployed them with "truffle migrate --reset"

Kevin Davis

@karzak

Thanks. I had to transpile to javascript and then truffle migrate --reset

Andrei Riaskov

@ARyaskov

@karzak You inspired us by machinomy/machinomy#240 on creating new workflow example -- https://github.com/machinomy/machinomy#sending-payments-through-channels

Thank you!

I could finally use machinomy in Windows.

Secret was that Sqlite3 dependency does not install with Node 10.X.

Use Node LTS (8.x) and all it's fine.

Andrei Riaskov

@ARyaskov

Use Node LTS (8.x) and all it's fine.

That’s great! I’ll add it to README.md!

Hernán Di Pietro

@hernandp

@ARyaskov I noted this on Windows only. MacOS / Linux seem fine.

Thx por the support.

Hernán Di Pietro

@hernandp

I don't know why my freshnew machinomy folder broke under Windows. I'll report the issue ;)

@pkafei

Thanks for creating machinomy. Is machinomy only limited to two parties? Can you use machinomy in a network that has three parties or more?

Sergey Ukustov

@ukstv

@pkafei We are in process of expanding the approach to multiple parties. Like, code wise in progress.

Kevin Davis

@karzak

@ukstv @ARyaskov Have either of you tested the mainnet contract recently? The code I'm working on runs on Kovan/Ropsten but fails on mainnet with the typically ambiguous error:
gas required exceeds allowance or always failing transaction

the is Unidirectional specifically
