getLatestBlockhash

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.

Rama

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.

Blockhash (Recent)

A 32-byte hash derived from the bank's state at a given slot, included in every Solana transaction to prove the transaction was created recently and to prevent replay attacks. A blockhash remains valid for approximately 150 slots (~60–90 seconds at normal slot times); transactions submitted with an expired blockhash are rejected outright. Clients must fetch a fresh blockhash before signing and ideally reuse it for as short a window as possible to maximize landing probability.

Transacción

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.

getMultipleAccounts

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.

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.

getSignaturesForAddress

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.

RPC (Llamada a Procedimiento Remoto)

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.

Infraestructura

Nodo RPC

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.
