Relayer for Tornado mixer

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

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 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
   • 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
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
