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
• Enterprise — 10,000 blocks. Customization available on request.

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.
