Hi,

A new BE explorer version is available at [https://testnet-zebra.zcashexplorer.app/](https://testnet-zebra.zcashexplorer.app/).  
It is integrated with Zebra having the following functionality changes because of Zebra’s RPC capabilities:

- Blocks navigation is based on height and not on a time windows because the [getblockhashes - Zcash 6.2.0 RPC Docs](https://zcash.github.io/rpc/getblockhashes.html) is not available.
- The mempool size is shown based on the length of the tx in the mempool (raw\_mempool operation) instead of using mempoolinfo operation because it is not available.

I will appreciate any help on reviewing and testing.  
In two weeks it will be promoted to the ([testnet env](https://testnet.zcashexplorer.app/)).  
Two week after to mainnet if there are not major issues.

Best
