#!/usr/bin/env bash
# smoke-test.sh — StellarSettle testnet smoke test
#
# Deploys (or re-uses) the invoice-escrow, invoice-token, and
# payment-distributor contracts on Stellar testnet and runs one
# minimal happy-path lifecycle: create → fund → settle.
#
# Required environment variables (copy from .env.example and fill in):
#   STELLAR_NETWORK      testnet | futurenet | mainnet  (default: testnet)
#   ADMIN_SECRET         admin Stellar secret key
#   SELLER_SECRET        seller Stellar secret key
#   BUYER_SECRET         buyer Stellar secret key
#   PAYER_SECRET         payer Stellar secret key (settles the invoice)
#   USDC_TOKEN_ADDRESS   address of the USDC / payment token contract
#
# Optional — skip deployment and reuse existing contracts:
#   ESCROW_CONTRACT_ID
#   INV_TOKEN_CONTRACT_ID
#   DISTRIBUTOR_CONTRACT_ID
#
# Usage:
#   chmod +x scripts/smoke-test.sh
#   source .env && ./scripts/smoke-test.sh
