getTransaction - Solana

Example code for the getTransaction JSON-RPC method. Complete guide on how to use the getTransaction JSON-RPC method in the GetBlock Web3 documentation.

This method returns a confirmed transaction by signature, including its instructions, account keys, logs, and balance changes. Versioned transactions require maxSupportedTransactionVersion to be set.

Parameters

Parameter	Type	Required	Description
signature	string	Yes	Base58-encoded transaction signature
config	object	No	Configuration object controlling encoding and version support

Config Object

Field	Type	Required	Description
encoding	string	No	Transaction encoding: json, jsonParsed, base58, or base64
commitment	string	No	Commitment level: processed, confirmed, or finalized. Defaults to finalized
maxSupportedTransactionVersion	number	No	Highest transaction version the client can decode. Set to 0 for versioned transactions

Response Parameters

Parameter	Type	Description
jsonrpc	string	JSON-RPC protocol version ("2.0")
id	string	Request identifier matching the request
result	object	null

Result Object

Field	Type	Description
slot	number	Slot containing the transaction
blockTime	number	null
transaction	object	Transaction message and signatures in the requested encoding
meta	object	Execution metadata including fee, balances, logs, and compute units
version	number	string

Use Cases

• Receipt Rendering: Display instruction-level detail for a completed transfer

• Log Inspection: Read logMessages to debug a failing program invocation

• Balance Deltas: Compare preBalances and postBalances to compute net movement

• Compute Budgeting: Read computeUnitsConsumed to right-size a compute unit limit

• Token Transfer Parsing: Use jsonParsed encoding to extract SPL Token transfer amounts

Error Handling

Error Code	Message	Description
-32602	Invalid params	Signature is malformed or an unsupported encoding was requested
-32015	Transaction version (0) is not supported by the requesting client	maxSupportedTransactionVersion was omitted for a versioned transaction
-32011	Transaction history is not available from this node	The node does not retain the ledger range containing the signature
-32603	Internal error	Node failed to read the transaction from blockstore
