Continuously updated Monad validator peer sets (name records: endpoint + consensus key), harvested by speaking the discovery protocol directly — no node required. Generated off-node and refreshed every 30 minutes.
CORS-enabled, so browser dApps/explorers can fetch them directly. Each record is
{ secp, ip, port, authPort, seq }.
