# Enhanced Transactions Overview

> Transform complex Solana blockchain transactions into human-readable data with Helius Enhanced Transactions API. Parse transaction details, fetch history, and understand on-chain activity without manual decoding.

<Warning>
  The Enhanced Transactions API is a legacy product in maintenance mode. It still works and these pages remain available, but it is not receiving new parser types or feature work. For new builds, use [`getTransactionsForAddress`](/rpc/gettransactionsforaddress) for transaction history and backfill, and the [Wallet API](/wallet-api/overview) for human-readable wallet data.
</Warning>

## What is the Enhanced Transactions API?

The Enhanced Transactions API transforms complex Solana transactions into human-readable data. Instead of manually decoding instruction data and account lists, you receive clear, structured details about transfers, swaps, NFT activities, and more.

It exposes two endpoints:

* `POST /v0/transactions` — parse individual or multiple transaction signatures. See [Parse Transactions](/enhanced-transactions/parse-transactions).
* `GET /v0/addresses/{address}/transactions` — fetch human-readable transaction history for an address. See [Transaction History](/enhanced-transactions/transaction-history).

Both support filtering by transaction type (for example `NFT_SALE`, `SWAP`, `TRANSFER`) via the `type` parameter.

## When to use this

* You already have an integration built on Enhanced Transactions and need the reference.
* You want pre-parsed, human-readable descriptions of individual transactions or an address's history.
* You are displaying transaction activity to end users (wallets, portfolio trackers, explorers).

For new projects, prefer [`getTransactionsForAddress`](/rpc/gettransactionsforaddress) (history and backfill) or the [Wallet API](/wallet-api/overview) (REST endpoints for wallet data).

Each parsed transaction includes:

* **Description** — a human-readable summary of what happened.
* **Type** — the transaction category (`TRANSFER`, `SWAP`, `NFT_SALE`, and others).
* **Source** — the program that executed the transaction.
* **Native transfers** — SOL movements between accounts.
* **Token transfers** — SPL token movements.
* **Events** — high-level event summaries.
* **Fee information** — transaction fees and the fee payer.
* **Timestamps** — when the transaction was processed.
