# Relayer for Tornado Cash [![Build Status](https://github.com/tornadocash/relayer/workflows/build/badge.svg)](https://github.com/tornadocash/relayer/actions) [![Docker Image Version (latest semver)](https://img.shields.io/docker/v/tornadocash/relayer?logo=docker&logoColor=%23FFFFFF&sort=semver)](https://hub.docker.com/repository/docker/tornadocash/relayer)
|
||||||
|
|
||||||
|
## Run locally
|
||||||
|
|
||||||
|
1. `npm i`
|
||||||
|
2. `cp .env.example .env`
|
||||||
|
3. Modify `.env` as needed
|
||||||
|
4. `npm run start`
|
||||||
|
5. Go to `http://127.0.0.1:8000`
|
||||||
|
6. In order to execute withdraw request, you can run following command
|
||||||
|
|
||||||
|
```bash
|
||||||
|
curl -X POST -H 'content-type:application/json' --data '<input data>' http://127.0.0.1:8000/relay
|
||||||
|
```
|
||||||
|
|
||||||
|
Relayer should return a transaction hash.
|
||||||
|
|
||||||
|
_Note._ If you want to change contracts' addresses go to [config.js](./config.js) file.
|
||||||
|
|
||||||
|
## Deploy with docker-compose
|
||||||
|
|
||||||
|
docker-compose.yml contains a stack that will automatically provision SSL certificates for your domain name and will add a https redirect to port 80.
|
||||||
|
|
||||||
|
1. Download docker-compose.yml
|
||||||
|
2. Change environment variables for `kovan` containers as appropriate
|
||||||
|
- add `PRIVATE_KEY` for your relayer address (without 0x prefix)
|
||||||
|
- set `VIRTUAL_HOST` and `LETSENCRYPT_HOST` to your domain and add DNS record pointing to your relayer ip address
|
||||||
|
- customize `RELAYER_FEE`
|
||||||
|
- update `RPC_URL` if needed
|
||||||
|
- update `REDIS_URL` if needed
|
||||||
|
3. Run `docker-compose up -d`
|
||||||
|
|
||||||
|
## Run as a Docker container
|
||||||
|
|
||||||
|
1. `cp .env.example .env`
|
||||||
|
2. Modify `.env` as needed
|
||||||
|
3. `docker run -d --env-file .env -p 80:8000 tornadocash/relayer`
|
||||||
|
|
||||||
|
In that case you will need to add https termination yourself because browsers with default settings will prevent https
|
||||||
|
tornado.cash UI from submitting your request over http connection
|
||||||
|
|
||||||
|
