Leitura rápida

Comece pela explicação mais curta e útil antes de aprofundar.

A Solana-focused infrastructure provider offering dedicated RPC nodes, DAS API access, Geyser-based webhooks, the LaserStream ultra-low-latency streaming product, and enhanced transaction parsing APIs that decode raw instruction data into human-readable event objects. Helius is widely used by developers for its generous free tier, Solana-specific tooling (NFT APIs, token metadata enrichment), and reliable globally distributed RPC endpoints.

Ramo

Nó 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.

Ramo

DAS (Digital Asset Standard) API

A unified RPC API specification, originated by Metaplex and adopted by major RPC providers, that provides indexed, queryable access to Solana digital assets including regular NFTs, compressed NFTs (cNFTs), and fungible tokens through methods like getAsset, getAssetsByOwner, getAssetsByGroup, and searchAssets. DAS abstracts away the complexity of reading raw Metaplex account data and reconstructing compressed NFT state from concurrent Merkle trees, making it the standard NFT data layer for wallets and marketplaces.

Ramo

Webhook

An HTTP callback mechanism used by Solana infrastructure providers like Helius to push real-time notifications to a developer-specified URL whenever a monitored address receives or sends a transaction, an account changes, or a specific program emits a log. Webhooks eliminate the need for client-side polling and are typically backed by Geyser-based indexers to ensure all on-chain events are delivered reliably with low latency.

Indexador

A specialized off-chain service that continuously ingests on-chain data (typically via a Geyser plugin or RPC polling) and stores it in a queryable database optimized for complex lookups, aggregations, and historical queries that the RPC node's account-state store cannot efficiently serve. Indexers power DAS APIs, portfolio trackers, analytics dashboards, and DEX order-history features by transforming Solana's append-only ledger into relational or document-oriented schemas with fast secondary indexes.

Infraestrutura

RPC (Chamada de Procedimento 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.

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.
