RPC Methods

The enumerated JSON-RPC endpoints exposed by Solana nodes, covering account queries (getAccountInfo, getMultipleAccounts, getProgramAccounts), block and transaction retrieval (getBlock, getTransaction), cluster metadata (getEpochInfo, getSlot, getVersion), and transaction submission (sendTransaction, simulateTransaction). Methods accept a Commitment parameter (processed, confirmed, finalized) to control the recency-vs-safety tradeoff of returned data.

Mental model

Mental model

Use the quick analogy first so the term is easier to reason about when you meet it in code, docs, or prompts.

Think of it as a building block that connects one definition to the larger Solana system around it.

Technical context

Technical context

Place the term inside its Solana layer so the definition is easier to reason about.

RPCs, validators, snapshots, indexing, and network plumbing.

Why builders care

Why builders care

Turn the term from vocabulary into something operational for product and engineering work.

This term unlocks adjacent concepts quickly, so it works best when you treat it as a junction instead of an isolated definition.

Concept graph

See the term as part of a network, not a dead-end definition.

These branches show which concepts this term touches directly and what sits one layer beyond them.

Branch

RPC (Remote Procedure Call)

The JSON-RPC 2.0 protocol interface through which clients communicate with Solana nodes to query chain state, submit transactions, and subscribe to events. Solana exposes a rich set of HTTP and WebSocket endpoints (e.g., getAccountInfo, sendTransaction) that abstract direct peer-to-peer network participation, making RPC the primary integration point for wallets, dApps, and indexers.

RPC Node
Open term
Branch

getAccountInfo

An RPC method that returns the complete on-chain state of a single account identified by its base-58 public key, including its lamport balance, owner program, executable flag, rent epoch, and raw data payload encoded as base64 or base58. It is the most fundamental read primitive in Solana development and is called at the specified commitment level, with the data field being null if the account does not exist.

Account
Open term
Branch

getTransaction

An RPC method that retrieves a confirmed or finalized transaction by its base-58 signature, returning the full message (account keys, instructions, address lookup tables), pre- and post-balances, inner instructions, log messages, and compute units consumed. The maxSupportedTransactionVersion parameter must be set to 0 to decode versioned transactions that use address lookup tables; the method returns null if the transaction has been purged from the node's transaction status cache (default retention is around 2 days on most RPC providers).

RPC Node

A Solana full node that stores ledger state and serves JSON-RPC and WebSocket requests from clients without participating in consensus or voting. RPC nodes must replay every transaction to maintain an accurate account state database, and high-throughput deployments typically run dedicated RPC nodes with large SSDs, high RAM (256 GB+), and high-bandwidth network connections to handle concurrent client load without impacting validator performance.

Infrastructurerpc-encoding

RPC Encoding

The data serialization format used to represent account data in Solana RPC responses. Supported encodings include base58 (human-readable but slow for large data), base64 (efficient binary encoding, most common), base64+zstd (compressed base64 for large accounts), and jsonParsed (structured JSON for known programs like SPL Token and System Program). The encoding parameter is specified per-request and affects response size and parse complexity on the client side.

getProgramAccounts (GPA)

An RPC method that scans all accounts owned by a given program and returns those matching optional memcmp (memory compare) and dataSize filters, making it the standard way to discover all state accounts for a protocol (e.g., all open order books, all user positions). GPA is resource-intensive because it performs a full account-store scan on the RPC node; many public endpoints rate-limit or disable it, which is why purpose-built indexers and services like Helius are used in production to serve GPA-equivalent queries at scale.
