# propose-bank-send.sh — submit a bank.send proposal to a DAO's proposal-single module.
#
# The canonical first-proposal pattern: agent address proposes a treasury transfer,
# the sub-DAO votes (1-of-1 auto-passes), VetoConfig timelock opens, vetoer can veto
# during the window, anyone can execute after.
#
# Usage:
#   propose-bank-send.sh \
#     --proposal-module juno1propmod... \
#     --title           "Pay vendor invoice 42" \
#     --description     "Quarterly retainer per agreement of 2026-05-01." \
#     --recipient       juno1vendor... \
#     --amount          100000000 \                # ujuno
#     --denom           ujuno \
#     --key             my-key \
#     --keyring-dir     /workspace/.my-keyring \
#     [--rpc https://juno-rpc.publicnode.com:443] \
#     [--chain-id juno-1] \
#     [--dry-run]
#
# Amount is in micro-units (ujuno = 1e-6 JUNO). 1 JUNO = 1000000ujuno.
#
# This script only submits the propose tx. To vote / execute, see the runbook
# in references/dao-dao.md §Member.
