# This file controls which services are enabled.

#   cp default.env .env
#
# Then copy and configure service-specific files:
#   cp environments/default.env.* environments/.env.*

# ============================================

# ------- Services Configuration -------

# Execution clients (Choose ONE)

START_NETHERMIND=false   # Nethermind (C#) - Good for RPC nodes, low memory
START_BESU=false         # Hyperledger Besu (Java) - Enterprise-grade
START_GETH=false         # Geth (Go) - Most popular, battle-tested
START_RETH=false         # Reth (Rust) - High performance, modern
START_ERIGON=false       # Erigon (Go) - Optimized for archive nodes

# ------- Consensus Clients -------
# Nimbus: Combined consensus + validator in one client
START_NIMBUS_CC_VC=false

# Lighthouse: Separate consensus and validator clients
START_LIGHTHOUSE_CC=false    # Lighthouse consensus (beacon node)
START_LIGHTHOUSE_VC=false    # Lighthouse validator (requires keystores)

# ------- Additional Services -------

# Execution API Multiplexer/Failover
# Provides redundancy by using multiple execution endpoints
START_EXECBACKUP=false

# MEV-Boost
# Maximize validator rewards via MEV (recommended for validators)
START_MEV_BOOST=false

# Nginx Reverse Proxy
# For exposing services via domain names
# See "Nginx Reverse Proxy" section in README.md for setup
# Configure domains in environments/.env.execution and .env.consensus
START_NGINX_PROXY=false

# Clef Signer (Geth only)
# Secure signing for private networks
START_CLEF=false

# Socat Interceptor
# For logging and debugging network requests
START_SOCAT=false

# ------- Version Configuration -------
# Docker image tags for each client
# Use 'latest' for latest stable, or specific versions like 'v4.5.0'
# Note: Nimbus uses 'amd64-latest' instead of 'latest'

C_VERSION=latest        # Consensus client version (use 'amd64-latest' for Nimbus)
E_VERSION=latest        # Execution client version
MEV_VERSION=latest      # MEV-Boost version

# ------- Network Selection -------
# Options: mainnet, sepolia

C_NETWORK=mainnet       # Consensus network
E_NETWORK=mainnet       # Execution network

# ------- Shared Configuration -------

# Enable REST APIs for all clients
ENABLE_REST_API=true

# Enable Metrics/Prometheus endpoints
ENABLE_METRICS=true

# Beacon API Port
BEACON_PORT=5052

# Execution RPC Port
EXECUTION_PORT=8545

# Logging Level
# Options: error, warn, info, debug, trace
DEBUG_LEVEL=info
