# Fund the mainnet LiquidityPoolETH with ETH and/or WETH (G4).
# Uses .env for PRIVATE_KEY, LIQUIDITY_POOL_ETH_MAINNET (or LIQUIDITY_POOL), ETHEREUM_MAINNET_RPC.
# Amounts via tags (not .env): --eth <amount>, --weth <amount> (in ETH), or --eth-wei / --weth-wei.
# If no amounts given and stdin is a TTY, prompts interactively.
#
# Usage:
#   ./scripts/deployment/fund-mainnet-lp.sh --eth 1.5 --weth 0.5
#   ./scripts/deployment/fund-mainnet-lp.sh --eth 1
#   ./scripts/deployment/fund-mainnet-lp.sh   # interactive prompt
#   ./scripts/deployment/fund-mainnet-lp.sh --dry-run  # no tx, show what would be sent
#
# Callable from other scripts: pass same tags; or source and call run_fund_mainnet_lp "${args[@]}"
