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 Endpoint

https://devnet-rpc.solayer.org

Currently Supported Methods

The following methods are fully implemented and available for use:

Method	Description
`getAccountInfo`	Returns all information associated with an account
`getBalance`	Returns the balance of an account
`getBlock`	Returns identity and transaction information about a confirmed block
`getBlocks`	Returns a list of confirmed blocks
`getLatestBlockhash`	Returns the latest blockhash
`getSignatureStatuses`	Returns the statuses of a list of signatures
`getTokenAccountBalance`	Returns the token balance of an account
`getTokenSupply`	Returns information about the total supply of an SPL Token type
`getTransaction`	Returns transaction details
`sendTransaction`	Submits a signed transaction to the cluster

Modified Methods

Method	Modification Details
`requestAirdrop`	Modified to airdrop exactly 0.1 SOL (Solayer devnet). The amount parameter has been removed for simplicity.

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:

{
  "jsonrpc": "2.0",
  "error": {
    "code": number,
    "message": string,
    "data": object
  },
  "id": number
}

Rate Limits

The devnet RPC endpoint has rate limiting in place to ensure fair usage. For production applications requiring higher limits, please contact the Solayer team.
