A persistent bidirectional connection to a Solana RPC node's WebSocket endpoint (typically on port 8900) that allows clients to receive real-time push notifications when on-chain state changes, rather than polling via HTTP. The subscription model supports account changes, program account changes, slot updates, root changes, signature confirmations, and log emission, each returning a subscription ID used to later unsubscribe.

Rama

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.

accountSubscribe

A WebSocket subscription method that pushes a notification to the client every time the data or lamport balance of a specified account changes, delivering the updated AccountInfo payload at the configured commitment level. It is commonly used by UIs to reactively update token balances, NFT ownership, or program state without polling, and each subscription is referenced by a numeric subscription ID returned upon successful registration.

logsSubscribe

A WebSocket subscription method that streams transaction log messages in real time as transactions are processed by the cluster, filterable by 'all' (every transaction), 'allWithVotes' (including vote transactions), or a specific program public key. It is the lowest-latency way for bots and monitoring systems to react to on-chain events emitted via Solana's msg! macro or Anchor's emit! macro without running a full validator or Geyser plugin.

Transaction Request (Solana Pay)

A Solana Pay protocol flow in which a QR code or link encodes an HTTPS URL; when scanned, the wallet performs a GET request to discover metadata (label, icon) and then a POST request with the user's public key, receiving a base64-encoded partially-signed transaction that the wallet can inspect, sign, and submit. This dynamic model enables programmable commerce flows such as NFT minting, coupon redemption, and multi-step checkout because the merchant server constructs the transaction at request time rather than encoding it statically.

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.

Infraestructura

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.

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.
