Dedicated nodes

You can also order dedicated nodes and pay for the node resource consumption only instead of per-request billing.

EVM Range limits

For eth_newFilter requests, Developer subscription plan users get capped at 10,000 blocks per request.

For the eth_getLogs, the caps are:

• Developer plan — 100 blocks
• Growth plan — 10,000 blocks
• Pro plan — 10,000 blocks
• Business plan — 10,000 blocks

Learn more about eth_getLogs limits by reading Understanding eth_getLogs limitations.

For users on the Developer subscription plan, Chainstack applies a specific range limit for certain requests.

This limit is designed to optimize the performance and resource allocation for our users on this plan.

Custom tracers on EVMs

Custom JavaScript tracers are available as customized solutions on the Enterprise plan on dedicated nodes.

Ethereum eth_simulateV1 supports only full node

Running eth_simulateV1 | Ethereum will yield only a full node response—i.e. the data from the latest 128 blocks. Archive data is not supported for this call and the node will respond with missing trie node.
