${var} — Watch label or chain to check. Empty = all watches. add-address:<0x… [chain]> is the shape the Telegram force-reply sends — it appends a new watch and exits (see step 0).

If ${var} is set, only monitor the watch with that label or watches on that chain.

Config

Reads memory/on-chain-watches.yml. If the file is missing or watches: [], offer to add the first watch via a Telegram force-reply (only if no add-address prompt was offered in the last 2 days of memory/logs/ — dedup so an unconfigured fork isn't nagged every run), then log ON_CHAIN_NO_CONFIG and exit cleanly (do not send an alert — empty config is not an error):

./notify "No addresses on watch yet. Paste one to monitor — a 0x… wallet, optionally its chain." \
  --force-reply --placeholder "0x… base" \
  --context "onchain-monitor::add-address"

The reply routes back as var=add-address:<0x… [chain]>, handled by the config-capture branch in step 0. Record FORCE_REPLY_OFFERED: add-address in the log when you send it.
