# pulse on Zoo mainnet (200200) — 1 transaction every 2 seconds.
#
# Zoo's validator fleet (zood-mv, 5/5) has been healthy the whole time; the chain
# sat at 14,795 for four days purely because NOTHING sent it transactions and the
# EVM builds no empty blocks. This is the sender.
#
# Key: `chain-traffic-key` (0x1B475A4C…A2A6), funded 1,000,000 ZOO from the
# treasury EOA 0x9011 (tx 0x27b74b41…). Deliberately a low-value bot key, not the
# treasury seed — a key that signs every 2s should not hold 1.97T ZOO.
