Ethereum OCR Feed Queries

These are queries to retrieve on-chain stats about Ethereum OCR feeds and node operator transmissions.

Ethereum Mainnet: Total OCR Feeds (counter):

-- Within the ethereum."transactions" table, lookup the individual OCR contracts being transmitted to by nodes.
SELECT COUNT(DISTINCT("to"))
FROM ethereum."transactions"
-- Use a random mix of well-known node operators to get all deployed OCR feeds.

Ethereum Mainnet: Total Successful Transmissions by Month (chart):
