As previously announced, the Hedera team is committed to maintaining the highest security standards for its services. In alignment with this commitment, we are progressing with the deprecation of insecure Hedera Consensus Service (HCS) Mirror Node endpoints. Below, you'll find an updated timeline and detailed plan of action to ensure minimal disruption for users.
Duration: 1 hour - Start: 10:00 AM CST
Duration: 12 hours - Start: 10:00 AM CST
Users should anticipate significant temporary disruption during this window.
The APIs have transitioned from the legacy hcs.<env>.mirrornode.hedera.com:5600 endpoints to the new <env>.mirrornode.hedera.com:443 endpoints. Older SDK versions are also affected by this change as they use the legacy HCS mirror node endpoints.
Old: hcs.previewnet.mirrornode.hedera.com:5600
New: previewnet.mirrornode.hedera.com:443
Old: hcs.testnet.mirrornode.hedera.com:5600
New: testnet.mirrornode.hedera.com:443
Old: hcs.mainnet.mirrornode.hedera.com:5600
New: mainnet.mirrornode.hedera.com:443
Note: The mainnet-public.mirrornode.hedera.com address is not impacted and will still work as an alias of mainnet.mirrornode.hedera.com.
Java SDK: v2.20.0 or higher
JS SDK: v2.22.0 or higher
Go SDK: v2.23.0 or higher
Hedera Consensus Service (HCS) Mirror Node Endpoint Users: If you're currently using one of the old endpoints, please update your configuration to use the new standard endpoint: <env>.mirrornode.hedera.com:443.
By upgrading to the new endpoints, users will benefit from increased security and stability, ensuring a better overall experience when interacting with Hedera services.
We appreciate your cooperation and understanding during this transition period. If you have any questions or need support, please reach out on Discord.
