API_URL
INTERNAL_API_URL
STATE_CHANNEL_URL
NETWORK_ID

RESPONDER_PORT

I’m trying to run the follownig example: tutorials/state-channels-introduction.md at master · aeternity/tutorials · GitHub

Hi, you can check this demo. It is work with js-sdk 3.1.0 and node 2.3.0/2.5.0
With these parameters it is work with forgae node

(async function () {

    const compilerURL = 'https://compiler.aepps.com';

    const {
        Channel,
        Universal,
    } = require('@aeternity/aepp-sdk');

    const API_URL = 'http://localhost:3001';
    const INTERNAL_API_URL = 'http://localhost:3113';
    const NETWORK_ID = 'ae_devnet';
    
    
    const initiatorKeyPair = {
        publicKey: 'ak_2mwRmUeYmfuW93ti9HMSUJzCk1EYcQEfikVSzgo6k2VghsWhgU',

@fedecaccia Hey, the demo that you show is not supposed to run with forgae, but with bare aeternity node.

The example that Aleksey has pasted is working with the latest version of forgae.

Of course I think that you can use the ports from this demo to run the one that you are trying.

const API_URL = 'http://localhost:3001';
const INTERNAL_API_URL = 'http://localhost:3113';
const NETWORK_ID = 'ae_devnet'
url: 'ws://localhost:3001'

I hope this helps,
Martin
