Subject: [PATCH] fix: chainstack block limit exceeded (#2974)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## What ❔

Added support for chainstack developer and growth plan.

## Why ❔

I was getting the below error with chainstack's growth plan when I tried
run self deployed zksync hyperchain. To fix this, I have added
appropriate changes to the code.

```
ERROR zksync_eth_watch: Failed to process new blocks: Eth client error: JSON-RPC request get_logs(filter=Filter { from_block: Some(Number(6732838)), to_block: Some(Number(6757429)), block_hash: None, address: Some(ValueOrArray([0xadd82b0c015be3fb7e8410061b4f15d577b4207f, 0xd6ee28b24f87c1d634540699b00e9c37fdc7b3bd, 0x41b75786db38a486c99972c8322fcb14c4f000a2, 0x5d300908338b85bee3f30f2e0ad196fc1587b70d])), topics: Some([Some(ValueOrArray([0x4531cd5795773d7101c17bdeb9f5ab7f47d7056017506f937083be5d6e77a382, 0x23bc9f5dc037eb49c162fd08c2a4d43dfe70063149e140d502273168da0a0625, 0xd50ef21701c8ef211433b140724b8d6de471e7d822c8a616c3d424fe2d0e98a9]))]), limit: None }) failed: ErrorObject { code: InvalidParams, message: "Block range limit exceeded.
