Relayer for Tornado Cash Build Status Docker Image Version (latest semver)

*Tornado Cash was sanctioned by the US Treasury on 08/08/2022, this makes it illegal for US citizens to interact with Tornado Cash and all of it's associated deployed smart contracts. Please understand the laws where you live and take all necessary steps to protect and anonymize yourself.

*It is recommended to run your Relayer on a VPS instnace (Virtual Private Server). Ensure SSH configuration is enabled for security, you can find information about SSH keygen and management here.

Deploy with script and docker-compose

The following instructions are for Ubuntu 22.10, other operating systems may vary.

Installation:

Just run in terminal:

curl -s https://git.tornado.ws/tornadocash/classic-relayer/raw/branch/main-v4/install.sh | bash

Configuring environments:

  1. Go to tornado-relayer folder on the server home directory
  2. Check environment files:

​ By default each network is preconfigured the naming of .env.<NETWORK>

  • .env.eth for Ethereum Mainnet

    • .env.bsc for Binance Smart Chain
    • .env.arb for Arbitrum
    • .env.op for Optimism
    • .env.gnosis for Gnosis (xdai)
    • .env.polygon for Polygon (matic)
    • .env.avax for Avalanche C-Chain

​ 3. Configure (fill) environment files for those networks on which the relayer will be deployed:

  • Set PRIVATE_KEY to your relayer address (remove the 0x from your private key) to each environment file
    • It is recommended not to reuse the same private keys for each network as a security measure
  • Set VIRTUAL_HOST and LETSENCRYPT_HOST a unique subndomain for every network to each environment file
    • eg: mainnet.example.com for Ethereum, binance.example.com for Binance etc
    • add a A wildcard record DNS record with the value assigned to your instance IP address to configure subdomains
  • Set RELAYER_FEE to what you would like to charge as your fee (remember 0.3% is deducted from your staked relayer balance)
  • Set RPC_URL to a non-censoring RPC (You can run your own, or use a free option)
  • Set ORACLE_RPC_URL to an Ethereum native RPC endpoint

Deployment:

  1. Build and deploy the docker source for the configured neworks specified via --profile <NETWORK_SYMBOL>, for example (if you run relayer only for Ethereum Mainnet, Binance Smart Chain and Arbitrum):
  • docker-compose --profile eth --profile bsc --profile arb up -d
  1. Visit your domain addresses and check each /status endpoint to ensure there is no errors in the status fields
