# Fork from a specific block number for consistent testing
# WARNING: When using Balancer V2 or Uniswap V3 (subgraph-based sources),
# always fork from latest block to avoid state mismatch between subgraph and fork.
# Only use a fixed block when testing without subgraph-dependent liquidity sources.
#
# Leave empty to fork from latest block (recommended):
#ETH_BLOCKNUMBER=

# Or set a specific block for reproducible testing:

# Chain ID (1 for Ethereum mainnet, 137 for Polygon)
# Note: When changing networks, update token addresses and DEX configs in:
