getGenesisHash

Returns the genesis hash of the cluster. The genesis hash uniquely identifies a Solana cluster (mainnet-beta, testnet, devnet) and is immutable once the cluster is initialized. This is commonly used to verify that a client is connected to the correct network, preventing accidental cross-network operations such as sending mainnet transactions to devnet.

Parameters

This method does not accept any parameters.

Response

Returns a single value:
