universe/k8s/hanzo-mainnet/pulse.yaml

# pulse on Hanzo mainnet (36963) — 1 transaction every 3 seconds.
#
# Replaces the bash `chain-traffic` bot. Same job, but with an HTTP start/stop
# switch so it can be driven from lux.cloud without a redeploy, and per-chain
# funding checks so it refuses to spam a chain it cannot pay for.
#
# ONE SENDER PER CHAIN. chain-traffic must be scaled to 0 before this runs:
# two senders sharing an account race the same nonce, and neither makes
# progress (observed on Lux — pulse read sent=0 for minutes while the old bot
# held the nonce).
#
# Key: the EXISTING `hanzod-faucet` secret (~941 AI). Deliberately NOT the
# treasury EOA 0x9011 — a key that signs every 3s does not belong in the same
# blast radius as the org's funds.
