Scheduled

We will urgently upgrade our cdk-erigon client on the zkEVM Mainnet to version v2.61.24 on 2025-08-27 at 12:00 UTC.

This maintenance improves reliability and RPC behavior. Notable client-facing impacts:
• Batch RPC behavior: a configurable list of methods will no longer run inside batch requests. If your integration batches heterogeneous calls, you may see rejections for specific methods; send these as individual requests instead. 
• Clearer error reporting: more descriptive error when a block-by-hash lookup isn’t found during eth_getLogs, aiding quicker debugging. 

This release also includes internal stability improvements. No downtime is expected; however, brief connection interruptions and a small number of HTTP 503 responses may occur as services restart and resynchronize.
