#!/usr/bin/env bash
# Mint cXAUC and/or cXAUT on Chain 138 to the minter (owner) address.
# Amounts are always in TROY OUNCES (1 full token = 1 troy oz Au; 6 decimals).
#
# Usage:
#   ./scripts/mint-xau-chain138.sh <troy_ounces>              # mint both tokens (default)
#   ./scripts/mint-xau-chain138.sh <troy_ounces> --cxauc-only
#   ./scripts/mint-xau-chain138.sh <troy_ounces> --cxaut-only
#   MINT_TO=0x... ./scripts/mint-xau-chain138.sh <troy_ounces>   # recipient (default: deployer from PRIVATE_KEY)
#   DRY_RUN=1 ./scripts/mint-xau-chain138.sh 100
#
# Requires: PRIVATE_KEY, RPC_URL_138 (or RPC_URL) in .env
