# =============================================================================
# EXAMPLE VALUES FOR TESTING
# =============================================================================

# For testing on Arbitrum Goerli testnet:
# ARBITRUM_RPC_ENDPOINT=https://goerli-rollup.arbitrum.io/rpc
# ARBITRUM_WS_ENDPOINT=wss://goerli-rollup.arbitrum.io/ws

# For local development with anvil fork:
# ARBITRUM_RPC_ENDPOINT=http://localhost:8545
# ARBITRUM_WS_ENDPOINT=ws://localhost:8545

# =============================================================================
# PRODUCTION RECOMMENDATIONS
# =============================================================================

# For production, use premium RPC providers for better reliability:
# - Chainstack: wss://arbitrum-mainnet.core.chainstack.com/YOUR_API_KEY
# - Alchemy: wss://arb-mainnet.g.alchemy.com/v2/YOUR_API_KEY  
# - Infura: wss://arbitrum-mainnet.infura.io/ws/v3/YOUR_PROJECT_ID
# - QuickNode: wss://YOUR_ENDPOINT.arbitrum-mainnet.quiknode.pro/YOUR_TOKEN/

# Always use multiple fallback endpoints for high availability
# Consider geographic distribution of endpoints for better latency
