API Reference

Solayer’s RPC API provides compatibility with Solana’s JSON RPC API while introducing optimizations for the Solayer Chain architecture. This reference documents all supported methods, upcoming features, and deprecated endpoints.

​
HTTP Endpoints

​
Mainnet RPC Endpoint

For production applications:

​
Devnet RPC Endpoint (For Testing and Development)

For testing and development purposes:
The devnet RPC endpoint is specifically for devnet and testing purposes only. Use the mainnet RPC endpoint for production applications.

​
Currently Supported Methods

The following methods are fully implemented and available for use:

​
Modified Methods

​
Coming Soon

These methods are under development and will be available in future updates:
  • getFeeForMessage
  • getLargestAccounts
  • getProgramAccounts
  • getRecentPrioritizationFees
  • getSignaturesForAddress
  • getTokenAccountsByDelegate
  • getTokenAccountsByOwner
  • getTokenLargestAccounts

​
Unsupported Methods

The following methods are not supported:
  • getClusterNodes
  • getHighestSnapshotSlot
  • getInflationGovernor
  • getInflationRate
  • getInflationReward
  • getLeaderSchedule
  • getMaxRetransmitSlot
  • getMaxShredInsertSlot
  • getSlotLeader
  • getSlotLeaders
  • getStakeMinimumDelegation
  • getSupply
  • getVoteAccounts
  • minimumLedgerSlot

​
Deprecated Methods

These methods are supported but deprecated due to Solayer Chain’s architecture changes:
  • getBlockCommitment
  • getBlockHeight
  • getBlockProduction
  • getEpochInfo
  • getEpochSchedule
  • getBlockTime
  • getFirstAvailableBlock
  • getGenesisHash
  • getHealth
  • getIdentity
  • getMinimumBalanceForRentExemption
  • getRecentPerformanceSamples
  • getSlot
  • getTransactionCount
  • getVersion
  • isBlockhashValid

​
Notes on Deprecated Methods

Methods marked as deprecated are still functional but may not provide meaningful information due to Solayer’s architectural differences from Solana. For example, concepts like epochs and slots are handled differently in Solayer Chain’s high-throughput architecture.

​
Error Handling

All RPC methods follow standard JSON-RPC 2.0 error handling conventions. Errors will be returned in the following format:

​
Rate Limits

The devnet RPC endpoint has rate limiting in place to ensure fair usage. For production applications requiring higher limits, please use the mainnet RPC endpoint (https://mainnet-rpc.solayer.org) or contact the Solayer team.
