getAgGenesisCert

Returns the Alpenglow genesis certificate: the certificate over the first block produced under Alpenglow consensus. Returns null while the cluster is still running TowerBFT, which makes this the way to detect whether Alpenglow is active on a cluster.

Source

get_ag_genesis_cert

Available from Agave v4.3. A node running an earlier version answers with a Method not found error (-32601), which is different from null: null means the node supports the method and the cluster has not migrated. The Solana CLI exposes the same call as solana alpenglow-genesis-info.
