Overview

Package rpc provides the typed Solana JSON-RPC client. It embeds a jsonrpc.Client transport and exposes Solana-specific methods (GetAccountInfo, SendTransaction, …). For raw JSON-RPC transport only — without the Solana method surface — use the jsonrpc package directly.

WebSocket subscriptions live in the ws package; attach a *ws.Client to a *Client via WithWebSocket when you need both RPC and WS on one logical client.

Constants

View Source 
const MaxGetMultipleAccountsAddresses = 100

MaxGetMultipleAccountsAddresses is the per-request limit the Solana RPC server enforces on getMultipleAccounts. The SDK validates input length up-front so callers get a precise error instead of a vague "Invalid params" from the server.

View Source 
const MaxGetRecentPrioritizationFeesAddresses = 128

MaxGetRecentPrioritizationFeesAddresses is the per-request limit the Solana RPC server enforces on getRecentPrioritizationFees.

View Source 
const MaxGetSignatureStatusesSignatures = 256

MaxGetSignatureStatusesSignatures is the per-request limit the Solana RPC server enforces on getSignatureStatuses. The SDK validates input length up-front so callers get a precise error instead of a vague "Invalid params" from the server.

Functions

func DecodeTransactionError 

func DecodeTransactionError(raw any) error

DecodeTransactionError parses the server's raw err field into either a *TransactionError, an *InstructionError, or nil.

The raw value comes from simulateTransaction or getTransaction's meta.err and is the untyped JSON shape Solana returns:

  • nil (success)
  • a plain string like "BlockhashNotFound"
  • {"InstructionError": [<idx>, "<kind>"]}
  • {"InstructionError": [<idx>, {"Custom": <u32>}]}
  • {"InstructionError": [<idx>, {"<Kind>": <sub>}]}

Unrecognised shapes are returned as a plain fmt.Errorf rather than silently discarded.

func FirstOrZero 

func FirstOrZero[T any](opts []T) *T

FirstOrZero returns a pointer to opts[0] when non-empty, otherwise a pointer to a zero value of T. Used by methods that take a variadic config so the caller can omit the argument entirely.

Types

type AccountInfoCfg 

type AccountInfoCfg struct {
	Commitment     solana.CommitmentLevel `json:"commitment,omitempty"`
	Encoding       solana.Encoding        `json:"encoding,omitempty"`
	DataSlice      *DataSlice             `json:"dataSlice,omitempty"`
	MinContextSlot *uint64                `json:"minContextSlot,omitempty"`
}

AccountInfoCfg is the config object for account-data RPC methods that honour {commitment, encoding, dataSlice, minContextSlot}: GetAccountInfo, GetMultipleAccounts, GetProgramAccounts, GetTokenAccountsByOwner, GetTokenAccountsByDelegate.

func (AccountInfoCfg) MarshalJSON 

func (c AccountInfoCfg) MarshalJSON() ([]byte, error)

MarshalJSON injects the SDK's default encoding ("base64") into AccountInfoCfg before serialising. Account-data RPCs always need a concrete encoding so the SDK fills in base64 when the caller leaves it blank.

Centralising the default here pays off because five typed methods (GetAccountInfo, GetMultipleAccounts, GetProgramAccounts, GetTokenAccountsByOwner, GetTokenAccountsByDelegate) share this Cfg. Other Cfg types with only one or two callers inject defaults inline in the calling method instead, which avoids the alias-MarshalJSON ceremony for the rare paths.

type BlockCommitment 

type BlockCommitment struct {
	Commitment []uint64 `json:"commitment"`
	TotalStake uint64   `json:"totalStake"`
}

BlockCommitment is the decoded response of GetBlockCommitment.

type BlockProductionRange 

type BlockProductionRange struct {
	FirstSlot uint64 `json:"firstSlot"`
	LastSlot  uint64 `json:"lastSlot"`
}

BlockProductionRange describes the slot range covered by a GetBlockProduction response.

type BlockProductionResult 

type BlockProductionResult struct {
	Slot  uint64
	Value BlockProductionValue
}

BlockProductionResult is the decoded response of GetBlockProduction.

type BlockProductionValue 

type BlockProductionValue struct {
	ByIdentity map[string][2]uint64 `json:"byIdentity"`
	Range      BlockProductionRange `json:"range"`
}

BlockProductionValue is the data portion of a GetBlockProduction response.

type BlockTransaction 

type BlockTransaction struct {
	Transaction solana.EncodedData `json:"transaction"`
	Meta        *TransactionMeta   `json:"meta"`
	Version     any                `json:"version"`
}

BlockTransaction is a single entry in the transactions array of a GetBlock response.

type Client 

type Client struct {
	*jsonrpc.Client
}

Client is the typed Solana JSON-RPC client. It embeds *jsonrpc.Client so the underlying transport's Call / batching / retry surface is promoted directly.

	opts ...SendAndConfirmOption,
) (solana.Signature, error)

SendAndConfirmSignedTransaction sends an already-signed transaction and waits for confirmation. Unlike SendAndConfirmTransaction, it performs exactly one send attempt and cannot refresh the blockhash on expiry; use it when the caller has a fully prepared transaction and wants a simple fire-and-wait flow.

func (*Client) SendAndConfirmTransaction 

func (c *Client) SendAndConfirmTransaction(
	ctx context.Context,

	opts ...SendAndConfirmOption,
) (solana.Signature, error)

SendAndConfirmTransaction builds, sends, and waits for a Solana transaction to reach the requested commitment level.

The builder is called for each send attempt with the latest blockhash, so callers get automatic blockhash refresh: when a transaction's blockhash expires, SendAndConfirmTransaction fetches a fresh one, rebuilds via the builder, and resubmits — up to WithMaxBlockhashRetries times.

On success it returns the first-signature of the transaction (the payer's). On preflight failure it returns the error from the send call. On execution failure (detected via getSignatureStatuses) it returns the decoded error from DecodeTransactionError, which unwraps to *TransactionError or *InstructionError.

SimulateTransaction simulates the given transaction without broadcasting it. Encoding defaults to base64 when cfg.Encoding is empty.
