# OpenPay launch script — single-command go-live on Base mainnet.
#
# Prereqs:
#   1. Rust 1.95+ installed (`rustup default stable`).
#   2. A hot wallet private key with ETH on Base mainnet for gas
#      (~$5 of ETH covers thousands of USDC transfers).
#   3. The wallet pre-funded with whatever USDC float you'll be
#      sending out (refunds, payouts). For receive-only pilots you
#      need only ETH for gas on the eventual sweeper.
#   4. A domain pointed at this server, with Caddy/nginx terminating
#      TLS in front (see docs/deploy/Caddyfile.sample).
#
# This script bootstraps a single-instance deployment with the
# embedded Minigraf .graph file on disk. Multi-instance / HA
# requires a graph daemon in front (out of scope for this script).
