GetGenesisHash

Returns the genesis hash of the connected cluster.

Type: unary

Overview

GetGenesisHash returns the genesis hash, which uniquely identifies the Solana cluster (mainnet-beta, testnet, devnet, or a custom cluster). This is useful for verifying that your client is connected to the intended network.

The genesis hash is a 32-byte hash of the genesis block and remains constant for the lifetime of a cluster.

Parameters

This method does not accept any parameters.

Response

FieldTypeDescription
hashstringThe genesis hash as a base-58 encoded string

Usage Examples

Node.js

1const grpc = require('@grpc/grpc-js');
2const protoLoader = require('@grpc/proto-loader');
3
4const packageDef = protoLoader.loadSync('geyser.proto', {
5  keepCase: true, longs: String, enums: String, defaults: true, oneofs: true
6});
7const proto = grpc.loadPackageDefinition(packageDef).geyser;
8const client = new proto.Geyser('[IP_ADDRESS]:[PORT]', grpc.credentials.createInsecure());
9
10client.getGenesisHash({}, (err, response) => {
11  if (err) { console.error(err); return; }
12  console.log('Response:', response);
13});
