Rate limits

​
Solana-specific

  • Solana Mainnet:
    • Developer plan: 5 requests per second (RPS)
    • Growth plan: 50 requests per second (RPS)
  • Solana Devnet:
    • Developer plan: 25 requests per second (RPS)
    • Growth plan: 250 requests per second (RPS)

​
Arbitrum-specific

  • Arbitrum Mainnet: debug_traceBlockByNumber 20 RPS on all plans

​
BNB Smart Chain-specific

BSC limitation: On Binance Smart Chain, eth_getProof currently only works with the "latest", "earliest", "safe", "finalized", "pending" block tags. Using specific block numbers will result in an error. This limitation will be addressed in a future update.

​
All other protocols

For global plan RPS limits across all other protocols, see Requests per second (RPS) plan limits.

​
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.
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.

​
Fantom method limits

The following limits are applied on all subscription plans:
  • debug_traceBlockByNumber: 5 RPS
  • debug_traceBlockByHash: 5 RPS

​

Solana accounts excluded from indexing

The following Solana accounts are unavailable for querying:
  • TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA
  • kinXdEcpDQeHPEuQnqmUgtYykqKGVFq6CeVX5iAHJq6

​
Solana method availability

The following methods are available only on the paid plans:
  • getProgramAccounts
  • getLargestAccounts — this method is available only on Dedicated Nodes.
  • getSupply
  • getTokenAccountsByOwner

​
Solana archive methods availability

While most methods are supported on Solana Global Nodes, only the following methods can fetch archive data:
  • getSignaturesForAddress
  • getTransaction
  • getBlock
  • getBlocks
  • getBlockHeight
  • getBlockTime
  • getBlocksWithLimit
Note that this is only true for mainnet as there are no Solana archive nodes for Devnet.
