Solana RPC JSON Structures

Overview

Various Solana RPC methods return structured JSON objects with well-defined fields and nested data.

This page documents the shared JSON data structures reused across Solana RPC responses.

Start with the top-level structure returned by the RPC method you are using, then follow the linked sections for any nested objects it contains.

Reference	Details
Type definitions	`transaction-status-client-types`; `rpc-client-types`; `account-decoder-client-types`
Serialization behavior	`transaction-status`; `rpc`

The sections below are grouped into top-level response objects and shared structures. Each section begins with a reference table that links the structure to the RPC method or parent structure, response path, and type definition.

Top-Level Response Objects

Confirmed Blocks

Block-oriented RPC methods such as getBlock return confirmed blocks in this structure:

Reference	Details
Returned by	`getBlock`; the `block` field in `blockSubscribe` notifications
Response path	`result` in `getBlock`; `params.result.value.block` in `blockSubscribe`
Type Definition	`UiConfirmedBlock`

slot

u64

Slot that contains this transaction.

transaction

object | string | [string, "base58" | "base64"]

Encoded transaction payload. Uses the structure documented in Encoded Transaction Responses.

Simulation Results

simulateTransaction returns this object inside result.value. sendTransaction preflight failures use the same structure inside error.data. Preflight failures return a sparser subset of fields, with several fields set to null:

Reference	Details
Returned by	`simulateTransaction`; `sendTransaction` preflight failures in `error.data`
Response path	`result.value` in `simulateTransaction`; `error.data` in `sendTransaction` preflight failures

accounts

array[object | null] | null

Post-simulation snapshots for the addresses requested in simulateTransaction.accounts.addresses. Each element corresponds to the same index in the request and is either null or an account object using the same schema documented in Account Data. The data field depends on the requested account encoding.

err

string | object | null

Simulation error. Uses the structure documented in Transaction Errors. null indicates success.

innerInstructions

array[object] | null

Inner instructions captured during simulation. null unless CPI recording was requested. Uses the structure documented in Inner Instructions.

loadedAccountsDataSize

u32

Total number of account-data bytes loaded while simulating the transaction.

logs

array[string]

Program log output captured during simulation. This field is always serialized as an array and may be empty.

replacementBlockhash

object | null

Replacement blockhash the RPC node used when replaceRecentBlockhash was enabled.

returnData

object | null

Most recent instruction return data captured during simulation. Uses the structure documented in Return Data.

unitsConsumed

u64

Compute units consumed during simulation.

fee

u64 | null

Fee charged for the simulated transaction. null if simulation failed before fee calculation completed.

preBalances

array[u64] | null

Lamport balances before simulation, indexed to the transaction account list.

postBalances

array[u64] | null

Lamport balances after simulation, indexed to the transaction account list.

postTokenBalances

array[object] | null

Token balances after simulation. Uses the structure documented in Token Balances.

preTokenBalances

array[object] | null

Token balances before simulation. Uses the structure documented in Token Balances.

loadedAddresses

object | null

Loaded account addresses resolved from lookup tables. simulateTransaction currently serializes this field as an object, using empty arrays when no addresses were loaded. sendTransaction preflight failures may return null for this field in error.data. Uses the structure documented in Loaded Addresses.

Shared Structures

Encoded Transaction Responses

Transaction-oriented RPC methods embed transactions in an encoded wrapper using this structure:

Reference	Details
Included in	`transactions[]` in Confirmed Blocks; the shared `transaction`, `meta`, and `version` fields in Confirmed Transaction Responses
Response path	`transactions[]` in confirmed blocks; `result.transaction`, `result.meta`, and `result.version` in confirmed transaction responses

transaction

object | string | [string, "base58" | "base64"]

Encoded transaction payload. For JSON encodings, this uses the structures documented in Transactions or Accounts Only Transaction Responses. For binary encodings, this is a base-58/base-64 string or a [string, encoding] tuple.

Transactions

Transactions are quite different from those on other blockchains. Be sure to review Anatomy of a Transaction to learn about transactions on Solana.

Reference	Details
Included in	Encoded Transaction Responses; the `transaction` field in Confirmed Transaction Responses
Response path	`transaction`
Type Definitions	`UiTransaction`, `UiMessage`, `UiRawMessage`, `UiParsedMessage`

Encoding	Message shape	Instruction shape	Notes
`json`	`UiRawMessage`	Compiled instructions	`accountKeys` are base-58 strings. Versioned messages describe lookup tables in `addressTableLookups`, with resolved loaded addresses reported separately in metadata.
`jsonParsed`	`UiParsedMessage`	Parsed or partially decoded instructions	`accountKeys` are objects, and parsed versioned responses include lookup-table accounts.

JSON

The JSON structure of a transaction is defined as follows:

message

object

Defines the content of the transaction.

signatures

array[string]

A list of base-58 encoded signatures applied to the transaction. The list is always of length message.header.numRequiredSignatures and not empty. The signature at index i corresponds to the public key at index i in message.accountKeys. The first one is used as the transaction id.

JSON Parsed

The JSON parsed structure of a transaction follows a similar structure to the regular JSON format, with additional parsing of account and instruction information:

signatures

array[string]

Transaction signatures in wire order.

accountKeys

array[object]

Parsed account metadata for each transaction account. Uses the structure documented in Parsed Accounts.

Account Data

RPC methods and subscriptions that return account data use this structure:

Reference	Details
Returned by	`getAccountInfo`; `getMultipleAccounts`; the `value` field in `accountSubscribe` notifications
Response path	`result.value`; `result.value[]`; `params.result.value`
Type Definitions	`UiAccount`, `UiAccountData`, `UiAccountEncoding`, `ParsedAccount`

Account data also appears in these nested response objects:

Reference	Details
Included in	Simulation Results; the `account` field in response objects returned by `getProgramAccounts`, `getTokenAccountsByOwner`, `getTokenAccountsByDelegate`, and `programSubscribe`
Response path	`result.value.accounts[]`; `result[].account`; `result.value[].account`; `params.result.value.account`

JSON

{
  "data": ["", "base64"],
  "executable": false,
  "lamports": 88867121550052,

  "rentEpoch": 18446744073709551615,
  "space": 0
}

data

string | [string, "base58" | "base64" | "base64+zstd"]

Account data. If the requested encoding is binary, this is a plain base-58 string. If the encoding is base58, base64, or base64+zstd, this is [data, encoding].

executable

boolean

Whether the account contains a program and is therefore read-only.

lamports

u64

Lamports assigned to this account.

owner

string

Program owner pubkey, as a base-58 encoded string.

rentEpoch

u64

Epoch at which this account next owes rent.

space

u64 | null

Account data size in bytes. Current Solana RPC responses populate this field for encoded account responses.

JSON Parsed

When jsonParsed encoding is requested, the data field uses this parsed wrapper when a parser is available:

{

  "rentEpoch": 18446744073709551615,
  "space": 165
}

data

object | [string, "base64"]

Parsed account data wrapper. When a parser is available, this is {program, parsed, space}. If jsonParsed is requested but no parser is available, the RPC node falls back to [data, "base64"].

executable

boolean

Whether the account contains a program and is therefore read-only.

lamports

u64

Lamports assigned to this account.

owner

string

Program owner pubkey, as a base-58 encoded string.

rentEpoch

u64

Epoch at which this account next owes rent.

space

u64 | null

Account data size in bytes. Current Solana RPC responses populate this field for encoded account responses.

Parsed Accounts

Parsed transaction and accounts only responses represent account keys in this structure:

Reference	Details
Included in	Transactions; Accounts Only Transaction Responses
Response path	`message.accountKeys[]` in parsed transactions; `accountKeys[]` in accounts only responses
Type Definitions	`ParsedAccount`, `ParsedAccountSource`

  "writable": true
}

pubkey

string

Account address, as a base-58 encoded string.

signer

boolean

Whether this account signed the transaction.

source

"transaction" | "lookupTable"

Source of the account metadata. This field is transaction for static message accounts and lookupTable for loaded lookup-table accounts in transaction/accounts responses.

writable

boolean

Whether the transaction marks this account writable.

Address Table Lookups

Versioned transaction messages may include address table lookups:

addressTableLookups

array[object]

List of address table lookups used by a versioned transaction to dynamically load account addresses.

Transaction Status Metadata

Transaction execution metadata is returned in this structure:

Reference	Details
Included in	Encoded Transaction Responses; Confirmed Transaction Responses
Response path	`meta`
Type Definition	`UiTransactionStatusMeta`

The table below highlights fields whose presence changes across transaction response modes. Fields not listed here serialize the same way whenever metadata is available.

json / full covers full metadata responses in raw JSON form, including getTransaction responses with encoding: "json" and block responses with transactionDetails: "full". jsonParsed covers parsed transaction responses, and accounts covers block responses with transactionDetails: "accounts".

Field	`json / full`	`jsonParsed`	`accounts`
`innerInstructions`	`array \| null`	`array \| null`	omitted
`logMessages`	`array \| null`	`array \| null`	omitted
`loadedAddresses`	`object`	omitted	omitted
`returnData`	`object \| undefined`	`object \| undefined`	omitted
`computeUnitsConsumed`	`u64 \| undefined`	`u64 \| undefined`	omitted
`costUnits`	`u64 \| undefined`	`u64 \| undefined`	omitted
`rewards`	`array \| null`	`array \| null`	`array \| null \| omitted`

In accounts responses, rewards is omitted when showRewards is false. Otherwise it serializes as an array or null.

Transaction Errors

Transaction errors serialize as a string or a variant-tagged object:

Reference	Details
Included in	Transaction Status Metadata; Simulation Results
Response path	`err`
Type Definition	`UiTransactionError`

Simple variants appear as a string:

"BlockhashNotFound"

transactionError

string | object

Serialized transaction error value.

Variants with additional data appear as an object, for example:

{
  "InstructionError": [
    0,
    {
      "Custom": 1
    }
  ]
}

transactionError
