# verify-tx.sh — poll for tx inclusion, extract event attributes, surface common needs.

# Useful after instantiate-subdao.sh or propose-bank-send.sh — captures the
# follow-up data (contract addresses for instantiates, proposal_id for proposals)
# without writing ad-hoc jq each time.
#
# Usage:
#   verify-tx.sh --txhash <HASH> [--rpc <URL>] [--timeout 30]
#
# Block time on Juno is ~5–6s. Default timeout is 30s (5–6 polls); raise for slow nodes.
