Network Presets

The Privacy Boost CLI includes built-in network presets for common configurations.

Available Presets

OP Sepolia Testnet

For testing on Optimism’s Sepolia testnet:

privacy-boost --network op-sepolia [command]

Aliases: op-sepolia, optimism-sepolia, opsepolia Configuration:

server_url = "https://optimism.sepolia.privacyboost.io"
rpc_url = "https://sepolia.optimism.io"
weth_contract_address = "0x4200000000000000000000000000000000000006"

chain_id and shield_contract_address are auto-discovered from the server’s /api/v1/info endpoint at runtime.

OP Mainnet

There is no built-in --network preset for mainnet yet. Point server_url at the mainnet endpoint via a config file or environment variable:

server_url = "https://optimism.privacyboost.io"
rpc_url = "https://mainnet.optimism.io"
weth_contract_address = "0x4200000000000000000000000000000000000006"

As with the testnet preset, chain_id and shield_contract_address are auto-discovered from /api/v1/info.

Custom Configuration

Configuration File

Create a custom configuration at ~/.privacy-boost/config.toml:

# Custom network configuration
server_url = "https://my-indexer.example.com"
chain_id = 1
shield_contract_address = "0x..."
weth_contract_address = "0x4200000000000000000000000000000000000006"
rpc_url = "https://mainnet.infura.io/v3/YOUR_KEY"
timeout_secs = 60

Load automatically or specify path:

# Uses ~/.privacy-boost/config.toml automatically
privacy-boost status

# Specify custom path
privacy-boost --config /path/to/config.toml status

Environment Variables

Override any configuration with environment variables:

export SERVER_URL="https://custom-indexer.com"
export CHAIN_ID=1
export RPC_URL="https://mainnet.infura.io/v3/YOUR_KEY"
export SHIELD_CONTRACT_ADDRESS="0x..."
export WETH_CONTRACT_ADDRESS="0x..."

privacy-boost status

Priority Order

Configuration is resolved in this order (later overrides earlier):

Default values
Network preset (--network)
Configuration file (~/.privacy-boost/config.toml)
Custom config file (--config)
Environment variables

Initialize Configuration

Create a configuration file from a preset:

# Create OP Sepolia config
privacy-boost init --network op-sepolia

# View created config
cat ~/.privacy-boost/config.toml

If ~/.privacy-boost/config.toml already exists, init will skip and warn you. Delete the existing file first to reinitialize. You can also import an existing config file as the default:

privacy-boost init --config /path/to/my-config.toml

Multiple Configurations

Use the --config flag to point at different config files per command:

privacy-boost --config ~/.privacy-boost/mainnet.toml balances
privacy-boost --config ~/.privacy-boost/sepolia.toml balances

RPC Provider Recommendations

Public RPC Endpoints

Network	Provider	URL
OP Sepolia	Optimism	`https://sepolia.optimism.io`
OP Sepolia	PublicNode	`https://optimism-sepolia.publicnode.com`

Private RPC Providers

For higher rate limits, use a dedicated RPC provider:

Alchemy: https://opt-sepolia.g.alchemy.com/v2/YOUR_KEY
Infura: https://optimism-sepolia.infura.io/v3/YOUR_KEY
