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 BNB Smart Chain, eth_getProof only works against named block tags such as "latest". A specific block number returns the error proofs are available only for the 'latest' block. This is a constraint of the BSC node client, not Chainstack.

​
Cronos-specific

  • Cronos Mainnet archive: debug_traceBlockByNumber 10 RPS on all plans

​
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.
Need a larger range? Dedicated nodes support custom block-range limits on request.

​
EVM disabled debug methods

The following debug methods are disabled on EVM chains:
  • debug_executionWitness
  • debug_executionWitnessByBlockHash
  • debug_executePayload

​
Custom tracers on EVMs

EVM debug and trace methods accept two kinds of tracers:
  • Native (built-in) tracers — selected by name, such as callTracer. Available on shared nodes, including Global Nodes; the exact set depends on the protocol (see below).
  • Custom JavaScript tracers — where you pass raw JavaScript as the tracer argument. These are disabled on shared nodes and are available as customized solutions on the Enterprise plan on dedicated nodes.

​
Available native tracers

The following native tracers are enabled by default on all EVM chains:
  • 4byteTracer
  • callTracer
  • prestateTracer
  • noopTracer
Ethereum (Mainnet, Sepolia, and Hoodi) additionally supports:
  • flatCallTracer
  • muxTracer
  • erc7562Tracer
See Debug and Trace | Ethereum for a description of each tracer.

​
Disabled tracer error

Requesting a tracer that isn’t enabled on the node—a custom JavaScript tracer, or a native tracer not available on that protocol—returns: 
{
  "error": {
    "code": -32612,
    "message": "Custom tracers are disabled by default. See https://docs.chainstack.com/docs/limits for details."
  }
}

​
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 method limits

The following per-method RPS limits apply identically across all regions:
MethodRPS
getBlockTime500
getBlock400
getTokenSupply300
getTokenAccountsByOwner80
getSupply2
getLargestAccounts0 — available on Dedicated Nodes only
getTokenLargestAccounts0 — available on Dedicated Nodes only
getProgramAccounts — unfiltered requests to large programs are blocked; always use dataSize or memcmp filters:
  • Chainstack Global Network global1 RPS: 3
  • Chainstack Cloud London lon1 RPS: 10
  • Chainstack Cloud New York City nyc1 RPS: 3
The getConfirmedBlock method was removed in Agave 2.0 and returns Method not found on current validators. Use getBlock instead.
Architectural limits (set by Solana, not Chainstack):

​
Solana accounts excluded from indexing

The following Solana accounts are excluded from the program-id secondary index and cannot be queried with getProgramAccounts. Use getTokenAccountsByOwner instead:
  • TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA — SPL Token Program
  • kinXdEcpDQeHPEuQnqmUgtYykqKGVFq6CeVX5iAHJq6 — Kin

​
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.
