# Relayer for Tornado Cash [](https://github.com/tornadocash/relayer/actions) [](https://hub.docker.com/repository/docker/tornadocash/relayer)
|
|
|
|
## 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](/docker-compose.yml) and [.env.example](/.env.example)
|
|
|
|
```
|
|
wget https://raw.githubusercontent.com/tornadocash/tornado-relayer/master/docker-compose.yml
|
|
wget https://raw.githubusercontent.com/tornadocash/tornado-relayer/master/.env.example -O .env
|
|
```
|
|
|
|
2. Setup environment variables
|
|
|
|
- set `NET_ID` (1 for mainnet, [networks list](#compatible-networks))
|
|
- set `HTTP_RPC_URL` rpc url for your ethereum node
|
|
- set `ORACLE_RPC_URL` - rpc url for mainnet node for fetching prices(always have to be on mainnet)
|
|
- set `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
|
|
- set `REGULAR_TORNADO_WITHDRAW_FEE` - fee in % that is used for tornado pool withdrawals
|
|
- set `REWARD_ACCOUNT` - eth address that is used to collect fees
|
|
- update `AGGREGATOR` if needed - Contract address of aggregator instance.
|
|
- update `CONFIRMATIONS` if needed - how many block confirmations to wait before processing an event. Not recommended
|
|
to set less than 3
|
|
- update `MAX_GAS_PRICE` if needed - maximum value of gwei value for relayer's transaction
|
|
- update `BASE_FEE_RESERVE_PERCENTAGE` if needed - how much in % will the network baseFee increase
|
|
- set `TELEGRAM_NOTIFIER_BOT_TOKEN` and `TELEGRAM_NOTIFIER_CHAT_ID` if your want get notify to telegram
|
|
|
|
If you want to use more than 1 eth address for relaying transactions, please add as many `workers` as you want. For
|
|
example, you can comment out `worker2` in docker-compose.yml file, but please use a different `PRIVATE_KEY` for each
|
|
worker.
|
|
|
|
3. Run `docker-compose up -d`
|
|
|
|
## V5 Migration Guide
|
|
|
|
This guide is intended to help with migration from Relayer v4 to v5.
|
|
|
|
1. Stop relayer
|
|
|
|
```
|
|
docker-compose down
|
|
```
|
|
|
|
2. Download the latest version of relayer`s docker compose file
|
|
|
|
```
|
|
wget https://raw.githubusercontent.com/tornadocash/tornado-relayer/master/docker-compose.yml
|
|
```
|
|
|
|
3. Check your environment variables, add new ones if needed
|
|
|
|
4. Run updated docker compose file
|
|
|
|
```
|
|
docker-compose up -d --pull
|
|
```
|
|
|
|
## Run locally
|
|
|
|
1. `yarn`
|
|
2. `cp .env.example .env`
|
|
3. Modify `.env` as needed
|
|
4. `yarn 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/v1/tornadoWithdraw
|
|
|
|
```
|
|
|
|
Relayer should return a job id in uuid v4 format.
|
|
|
|
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
|
|
|
|
## Run geth node
|
|
|
|
It is strongly recommended that you use your own RPC node. Instruction on how to run full node with `geth` can be
|
|
found [here](https://github.com/tornadocash/rpc-nodes).
|
|
|
|
## Monitoring
|
|
|
|
### Basic

|
|
|
