Using contract address 0x2f4bdafb22bd92aa7b7552d270376de8edccbc1e (CheezWizards) on mainnet, I receive the following errors in console and the page fails to render.

First, it said docker wasn't detected as running. Using it with sudo had fixed it, but yet not exporting the frontend. After manually creating /usr/share/nginx/html and putting user-group docker with RW permissions, docker-composer can now run without sudo. But it yet isn't exporting to /nginx/html.

Context

• 0x-lauch-kit running on a external machine running ubuntu 19.04 using mesh:7-0xv3 on Kovan testnet (42)
• modified another 0x-launch-kit-frontend only instance to support a new token, contract is deployed on (and only !) Kovan testnet.
  Contract address for all other networks was set to the kovan address , although they do not exist there - that was required because otherwise I got another error and it did not work at all.

    "tokens": [
        {
            "symbol": "feo1",
            "name": "Iron Ore Token Type1",
            "primaryColor": "#333333",
            "icon": "assets/icons/zrx.svg",
            "addresses": {

            },
            "decimals": 18,
            "displayDecimals": 4
        },

Everything was working fine

https://github.com/SvenMeyer/commx-frontend

On external machine running the 0x-lauch-kit with the backend :

• changed within docker-compose.ymlto mesh:latest
• restarted 0x-lauch-kit docker-compose up

Accessed 0x-launch-kit backend (on on a external machine running ubuntu 19.04) using the same modified 0x-frontend (with support for custom token).
Got error message when trying to create order for the custom token - all other existing standard token were working fine.

I keep getting this issue. Any help regarding this how do i resolve this ?

i cant figure this out for the life of me

my terminal screen givin this error

https://demo.0x.org/marketplace#/erc721/ currently shows three different Cheeze Wizards. One of them has a price of -906.50 ETH.

Clicking on this Cheeze Wizard leads to a a blank white page and produces an error in the JavaScript console:

When doing Buy market and not buy limit it's not stopping you if you don't have enough token balance to pay fee (we are using custom ERC20 token for fees), instead it let you process the transaction all the way and at the end it shows the transaction has failed but the ETH fees are gone.

When MetaMask connection is established, the web page appears as a white screen.
what is the source of the problem

Or does this only work for ETH projects?

tried but get leak of memory and pc breaks
not sure why seems one error when try to connect the address of infura???

Steps to recreate:

• Run wizard
• Choose mainnet
• Notice that the frontend is running with Ganache

Assign a volume to backend so that orders are persisted across restarts.

Document a production ready database.

Database currently lives inside the container in the working directory as database.sqlite. To make a copy of the database run:

docker cp <container id>:/usr/src/app/database.sqlite .

I want to ask if I can run this code in GoDaddy shared hosting ssh and how can I add a fixed withdrawal fees inside and lastly how to add tokens to the Exchange thank you .

is this project customizable?

Hi guys,
Similar issue in your erc20 demo, now on my deployment.

I've managed to install it but there's no way I can do any buy / sell orders on market or limit.

although I have ETH, WETH, ZRX in my wallet, I've unlocked them, there's no way. I click on buy button but nothing happens:

also in the console I can see loads of errors:

Do I have to enable in the firewall these ports or what should I do ?

Also, is there any proper tutorial on how to add my own tokens?

I use ropsten test network

Thank you!

after doing everything as i see in you tube when i load the code it says "bash: docker-compose: command not found"
can someone help

Hello, I’m trying to launch exchange on the xDai network. I tried different things but all of them didn’t work.

I changed the network ID to 100 in the build.ts file then built it then : node ./lib/index.js.
On the wizard I choose custom network then inputed the xDAI rpc address.
.....

when I open the frontend, it gives me a blank page. (I changed the network ID of mainnet to random number and it gave the same blank page)

Can you please help me or guide me how to connect it to Custom network like xDai and Binance chain.

I get "403 Forbidden nginx/1.15.12 error"

Since 0x can have multiple different relayer strategies:

• Matching
• Open Orderbook
• Coordinator

Document clearly the strategy of Launch Kit and what behaviour a developer should expect (i.e negative spread will not be automatically matched and its a profit making opportunity for a keen observer or arb bot).

V2 assumed ZRX was the fee asset data and no prompt was made. In V3 Fee Asset data can be any token and isn't being set in the wizard.

MAKER_FEE_ASSET_DATA and TAKER_FEE_ASSET_DATA should be set in the backend container.

Prompt for the ERC20 contract address and encode as ERC20 asset data for the golden path.

As you can see from the below attached screenshot. The error from console. Market sells work as expected. Limit orders also do not match as expected. The only thing currently working as expected is the market sell for orders.

Note: limit orders will stay/show on the exchange however the spread is incorrectly displayed. Please check the second attached image for reference.

Using the Kovan Network on Ubuntu 18.04.2

I deployed 0x-launch-kit locally on docker in windows OS , after I run this command : npx @0x/launch-kit-wizard && docker-compose up Then When I open http://localhost:3001/ I show nginx result 403 Forbidden, I am also deployed 0x-launch-kit to Digitalocean droplet docker I showed the same error, Other thing when I browse to /usr/share/nginx/html directory inside nginx container I didn't show index.html please can you solve problem ?

I also had an error with docker desktop running before this.

Repro steps:

1. Set REACT_APP_COLLECTIBLE_ADDRESS to the 721 contract address of your choice in .env (I'm using 0x2f4bdafb22bd92aa7b7552d270376de8edccbc1e for CheezWizards)
2. yarn start
3. App does not load your collectibles from this contract address and instead defaults to Axie Infinity (the default)

It doesn't even look like there's code to read in this environment variable??? src/constants.ts does not look at this var name

Can anyone share any alternative which is not deprecated similar to 0xproject

I want it, but I don't have enough knowledge. Can someone install this for me, payed

when i run docker-compose up
{"error_string":"403 Forbidden {"jsonrpc":"2.0","id":2,"error":{"code":-32600,"message":"project ID is required","data":{"reason":"project ID not provided","see":"https://infura.io/dashboard\"}}}","level":"error","msg":"blockwatch.Watcher error encountered","myPeerID":"16Uiu2HAmV5UdipLWW9UcvdCaggZhNQmEt64aZtoXx195YjSxVCfp","time":"2020-06-06T10:02:34Z"}
what's can i do?

Hey I am trying to find a resolution to this, also in the future can we have a FAQ/wiki for common problems or error code and fixes.
Thanks

Based on my discussions in Discord I realized that there is a missing step 2. in instructions:

1. Install Pre-requirements:
   Node.js > v8.x
   Yarn > v1.x
   Docker
   npx

2. Clone the repo:
   git clone https://github.com/0xProject/0x-launch-kit.git

3. Run the wizard
   npx @0x/launch-kit-wizard && docker-compose up

Also: Please be prepared to wait up to five (5) minutes to get all the background services properly running before trying to check your http://[host]:3001

The launch kit notes that the current version of the launch kit is designed with the "open order" relay variety. However, flat fees are not something the typical user is looking for and so a 'matching' system config would be valuable.

While 0x-launch-kit notes that "some elements would need to be changed" there is no documentation on what changes would need to be made and even the 0x docs lack good documentation on how to set up different relayer strategies.

This seems to be a significant gap to adoption. Since the 0x launch kit was clearly designed to make adoption more accessible I figured this was worth addressing in this channel that that 0x Launch Kit team should either have a version supporting matching order types or maintain more robust documentation on that.

When deploying to public infra the user currently has to edit the docker-compose.yml file and replace localhost. If this is known ahead of time (i.e docker machine) then we can prompt for this in the wizard.

Default to http://localhost:3000/v2.

The 0x Launch Kit sets up a forwarding contract which converts ETH to wETH and then does the 0x transaction. It seems there are two costs associated with this:

1. The gas fees of the ETH to wETH transaction.
2. The protocol fee of the swap (gas fee + protocol fee).
3. The gas fee of the assets switching wETH to ETH again.
4. The gas fee of returning the users transaction.

(Perhaps these are bundled in single transactions but, thats still all the fees.)

In the launch kit, we're asked to set a Maker/Taker fee, but it isn't very clear what costs we would expect to cover from those fees.

In the documentation we see that the protocol fee is "tx.gasprice * protocolFeeMultiplier" and that protocolFeeMultiplier is suggested to be roughly equal to 150000. But, it isn't clear what we should expect for the average tx.gasprice - and while that is the protocol fee from the 0x documentation, it doesn't note what we would expect in costs from the forwarder contract.

Any insights here?

Hello how can I make User's only trade my Token(Erc20) i.e Speedkingtoken to Ethererum .
Also they can withdraw Speedkingtoken.
Lastly do I need VPS to run the code because I watched the video ,can I run it via SSH hosting ,thank you .
