JPYC Network Activity
JPYC transfer metrics computed hourly from finalized Polygon blocks: event count, unique senders and receivers, volume, median and top receivers. Covers approximately 24 hours ending at the newest finalized hourly bucket; exact block and time range are in the response. Use for current JPYC usage metrics; not for wallet balances, price, news, supply or financial advice.
