Mainnet

The non-production public mainnet mirror node serves to help developers build their applications without running their own mirror node. For production-ready mainnet mirror nodes, please check out Arkhia, Dragonglass, or Ledger Works. When building your Hedera client via SDK, you can use setMirrorNetwork() and enter the public mainnet mirror node endpoint. The gRPC API requires TLS. The following SDK versions support TLS:

• Java: v2.0.6+

• JavaScript: v2.0.23+

• Go: v2.1.9+

Requests are throttled at 100 requests per second (rps). This may change in the future depending on performance or security considerations. At this time, no authentication is required.

Java

//You will need to upgrade to v2.0.6 or higher
Client client = Client.forMainnet();
client.setMirrorNetwork(Collections.singletonList("mainnet-public.mirrornode.hedera.com:443"))

JavaScript

//You will need to upgrade to v2.0.23 or higher
const client = Client.forMainnet()
client.setMirrorNetwork("mainnet-public.mirrornode.hedera.com:443")

Go

client := hedera.ClientForMainnet()
client.SetMirrorNetwork([]string{"mainnet-public.mirrornode.hedera.com:443"})
