An RPC method that returns a paginated, reverse-chronological list of transaction signatures that reference a given account address, along with each transaction's slot, block time, memo, and confirmation status. It is the standard way to walk the transaction history of a wallet or program account and accepts before and until signature parameters for cursor-based pagination through up to 1,000 signatures per call.

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.
Place the term inside its Solana layer so the definition is easier to reason about.
RPCs, validators, snapshots, indexing, and network plumbing.
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.
Use this compact block when you want to give an agent or assistant grounded context without dumping the entire page.

Use glossary context, relationships, mental models, and builder paths to get structured answers instead of generic chat output.
Optional: paste Anchor, Solana, or Rust code so the Copilot can map primitives back to glossary terms.
The Copilot will answer using the current term, related concepts, mental models, and the surrounding glossary graph.
These branches show which concepts this term touches directly and what sits one layer beyond them.
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.
An atomic unit of execution containing one or more instructions, a recent blockhash, and one or more signatures. All instructions in a transaction execute sequentially and atomically—if any instruction fails, the entire transaction reverts. Transactions have a 1,232-byte size limit (matching IPv6 MTU) and a default 200,000 CU budget.
A 64-byte Ed25519 digital signature over a transaction's message. Each signer in a transaction produces one signature. The first signature (from the fee payer) also serves as the unique transaction ID. Signature verification is parallelized in the TPU's sigverify stage using GPU acceleration.
These are the next concepts worth opening if you want this term to make more sense inside a real Solana workflow.
These entries are easy to mix up when you are reading quickly, prompting an LLM, or onboarding into a new layer of Solana.
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.
A Solana RPC method that returns the most recent blockhash along with the last valid block height for that blockhash, providing the two values needed to build and submit a transaction. Every Solana transaction must include a recent blockhash to prevent replay attacks; this method is typically called immediately before signing. The returned lastValidBlockHeight indicates when the blockhash expires, after which unsigned transactions using it will be rejected.
A Solana RPC method that fetches the account data for up to 100 public keys in a single request, returning an array of AccountInfo objects in the same order as the input keys. This batched approach is significantly more efficient than calling getAccountInfo repeatedly, reducing round trips and RPC load. It supports the same encoding and commitment parameters as getAccountInfo. Accounts that do not exist return null in the response array.

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.
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.
