# Solana Historical Data Overview & Tutorials

> Query Solana historical data with Helius: enhanced transaction history via getTransactionsForAddress, transfer history, and standard archival RPC methods like getBlock and getSignaturesForAddress.

## What is Solana historical data?

Solana's ledger is an append-only chain of blocks stretching back to genesis. Historical data means querying that ledger after the fact: a wallet's past transactions, the transfers a token has seen, the contents of a block, or the signatures that touched an address.

Helius gives you two ways to read it. Standard archival RPC methods (`getBlock`, `getSignaturesForAddress`, `getTransaction`, and more) mirror the native Solana JSON-RPC surface. On top of those, Helius adds enhanced methods that standard RPC can't match: `getTransactionsForAddress` returns full filtered transaction history in a single call, and `getTransfersByAddress` returns parsed, reconciliation-ready transfer records.

## Why Helius for historical data?

Unlike providers relying on shared BigTable infrastructure, Helius maintains dedicated archival nodes optimized for fast historical data retrieval. Data spans Solana genesis to present, is continuously updated, and fully supports versioned transactions and all program types.

## Which method should I use?

Start with `getTransactionsForAddress` for any address-based history work. Reach for the standard methods when you need raw block data or are wiring up existing Solana RPC tooling.
