# How to Fetch Solana Wallet Transaction History

> Get complete transaction history for any Solana wallet with balance changes for each transaction. Perfect for portfolio trackers, accounting tools, and analytics platforms.

<Note>
  The Wallet API is in Beta. Endpoints and response formats may change.
</Note>

## Overview

The Transaction History endpoint retrieves the complete transaction history for a Solana wallet using the Enhanced Transactions API. It returns human-readable, parsed transactions with balance changes for each transaction, in reverse chronological order (newest first).

The endpoint returns up to 100 transactions per request, so pagination is manual. Use the `before` parameter with `pagination.nextCursor` to fetch the next page, and read `pagination.hasMore` to know when more results are available. Each request is a single API call and costs 100 credits.

The `tokenAccounts` parameter controls whether transactions involving token accounts owned by the wallet are included:

* `balanceChanged` (recommended): includes transactions that changed token account balances, filtering spam.
* `none`: only direct wallet interactions.
* `all`: all token account transactions, including spam.

<Warning>
  The `tokenAccounts` filter relies on the `owner` field in token balance metadata, which was not available before slot 111,491,819 (\~December 2022). Transactions involving token accounts active before this slot may be missing. See the [getTransactionsForAddress tutorial](/rpc/gettransactionsforaddress#limitations-and-edge-cases) for a workaround.
</Warning>

## When to use this

Use the Transaction History API when you need to:

* **Display a transaction feed**: show users their complete transaction history.
* **Calculate PnL**: track gains and losses across all transactions.
* **Tax and accounting**: generate complete transaction reports for tax filing.
* **Portfolio analytics**: analyze trading patterns and activity.
* **Audit trails**: maintain complete records of wallet activity.
* **Balance reconstruction**: rebuild current balances from historical data.

## Quickstart

### Basic history query

Get the most recent transactions with balance changes:

<Tabs>
  <Tab title="JavaScript">
    ```javascript theme={"system"}
    const getTransactionHistory = async (address) => {
      const url = `https://api.helius.xyz/v1/wallet/${address}/history?api-key=YOUR_API_KEY`;

      const response = await fetch(url);
      if (!response.ok) {
        throw new Error(`HTTP error! status: ${response.status}`);
      }

      const data = await response.json();

      console.log(`Found ${data.data.length} transactions`);

      // Display recent transactions
      data.data.forEach(tx => {
        const date = new Date(tx.timestamp * 1000).toLocaleString();
        const status = tx.error ? 'Failed' : 'Success';

        console.log(`\n${status} - ${date}`);
        console.log(`Signature: ${tx.signature.slice(0, 20)}...`);
        console.log(`Fee: ${tx.fee} SOL`);

        // Show balance changes
        tx.balanceChanges.forEach(change => {
          const sign = change.amount > 0 ? '+' : '';
          console.log(`  ${sign}${change.amount} ${change.mint === 'SOL' ? 'SOL' : change.mint.slice(0, 8)}...`);
        });
      });

      return data;
    };

    getTransactionHistory("86xCnPeV69n6t3DnyGvkKobf9FdN2H9oiVDdaMpo2MMY");
    ```
  </Tab>

  <Tab title="Python">
    ```python theme={"system"}
    import requests
    from datetime import datetime

    def get_transaction_history(address: str):
        url = f"https://api.helius.xyz/v1/wallet/{address}/history"
        headers = {"X-Api-Key": "YOUR_API_KEY"}

        response = requests.get(url, headers=headers)
        response.raise_for_status()

        data = response.json()

        print(f"Found {len(data['data'])} transactions")

        # Display recent transactions
        for tx in data['data']:
            date = datetime.fromtimestamp(tx['timestamp']).strftime('%Y-%m-%d %H:%M:%S')
            status = 'Failed' if tx.get('error') else 'Success'

            print(f"\n{status} - {date}")
            print(f"Signature: {tx['signature'][:20]}...")
            print(f"Fee: {tx['fee']} SOL")

            # Show balance changes
            for change in tx['balanceChanges']:
                sign = '+' if change['amount'] > 0 else ''
                mint_display = 'SOL' if change['mint'] == 'SOL' else change['mint'][:8] + '...'
                print(f"  {sign}{change['amount']} {mint_display}")

        return data

    get_transaction_history("86xCnPeV69n6t3DnyGvkKobf9FdN2H9oiVDdaMpo2MMY")
    ```
  </Tab>

  <Tab title="cURL">

  <Tab title="JavaScript">
    ```javascript theme={"system"}
    const getAllTransactionHistory = async (address) => {
      let allTransactions = [];
      let before = null;

      do {

          ? `https://api.helius.xyz/v1/wallet/${address}/history?api-key=YOUR_API_KEY&before=${before}`
          : `https://api.helius.xyz/v1/wallet/${address}/history?api-key=YOUR_API_KEY`;

        const response = await fetch(url);
        const data = await response.json();

        before = data.pagination.hasMore ? data.pagination.nextCursor : null;

        console.log(`Fetched ${allTransactions.length} transactions so far...`);

      } while (before);

      console.log(`\nTotal transactions: ${allTransactions.length}`);
      return allTransactions;
    };

            params = {"api-key": "YOUR_API_KEY"}

            if before:
                params["before"] = before

            response = requests.get(url, params=params, headers={"X-Api-Key": "YOUR_API_KEY"})
            response.raise_for_status()

            data = response.json()
            all_transactions.extend(data['data'])

            print(f"Fetched {len(all_transactions)} transactions so far...")

            if not data['pagination']['hasMore']:
                break

            before = data['pagination']['nextCursor']

  }
}
```

### Field notes

* **`timestamp`**: Unix seconds. May be `null` for very recent transactions that haven't been fully processed yet.
* **`error`**: `null` for successful transactions; an error value for failed ones. Failed transactions still incur fees.
* **`balanceChanges`**: how the wallet's holdings changed in the transaction — a positive `amount` is tokens received, a negative `amount` is tokens sent or spent.
* **`mint`** (within `balanceChanges`): token mint address, or `"SOL"` for native SOL.
* **`amount`** (within `balanceChanges`): **human-readable**, already divided by `decimals` — `-0.05` means −0.05 SOL, not −0.05 lamports. This endpoint does not include a raw `amountRaw` field.

#### Example balance changes

```javascript theme={"system"}
// Swap: Sold 0.05 SOL, received 5 USDC
{
  "balanceChanges": [
    { "mint": "SOL", "amount": -0.05, "decimals": 9 },
    { "mint": "EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v", "amount": 5.0, "decimals": 6 }
  ]
}

// Simple transfer: Sent 10 USDC
{
  "balanceChanges": [
    { "mint": "EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v", "amount": -10.0, "decimals": 6 }
  ]
}
```

## Use cases

### Calculate total trading volume

Sum all transfers to get trading volume:

```javascript theme={"system"}
const calculateTradingVolume = async (address, tokenMint) => {
  const transactions = await getAllTransactionHistory(address);

  let totalVolume = 0;

  transactions.forEach(tx => {
    tx.balanceChanges.forEach(change => {
      if (change.mint === tokenMint) {
        totalVolume += Math.abs(change.amount);
      }
    });
  });

  console.log(`Total ${tokenMint} volume: ${totalVolume}`);
  return totalVolume;
};

// Example: Calculate total USDC volume
calculateTradingVolume(
  "86xCnPeV69n6t3DnyGvkKobf9FdN2H9oiVDdaMpo2MMY",
  "EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v" // USDC
);
```

### Generate a tax report

Create a transaction report for tax filing:

```javascript theme={"system"}
const generateTaxReport = async (address, year) => {
  const transactions = await getAllTransactionHistory(address);

  const startDate = new Date(`${year}-01-01`).getTime() / 1000;
  // Set to end of December 31st (23:59:59.999) to include all transactions from that day
  const endDate = new Date(`${year}-12-31T23:59:59.999Z`).getTime() / 1000;

  const taxableTransactions = transactions
    .filter(tx => tx.timestamp >= startDate && tx.timestamp <= endDate)
    .map(tx => ({
      date: new Date(tx.timestamp * 1000).toISOString(),
      signature: tx.signature,
      fee: tx.fee,
      balanceChanges: tx.balanceChanges,
      explorerUrl: `https://orbmarkets.io/tx/${tx.signature}`
    }));

  console.log(`Found ${taxableTransactions.length} transactions in ${year}`);

  // Export as JSON
  const report = {
    address,
    year,
    transactionCount: taxableTransactions.length,
    transactions: taxableTransactions
  };

  console.log(JSON.stringify(report, null, 2));
  return report;
};

generateTaxReport("86xCnPeV69n6t3DnyGvkKobf9FdN2H9oiVDdaMpo2MMY", 2024);
```

### Track failed transactions

Find all failed transactions to understand errors:

```javascript theme={"system"}
const getFailedTransactions = async (address) => {
  const data = await getTransactionHistory(address);

  const failed = data.data.filter(tx => tx.error !== null);

  console.log(`Found ${failed.length} failed transactions`);

  failed.forEach(tx => {
    const date = new Date(tx.timestamp * 1000).toLocaleString();
    console.log(`\n${date}`);
    console.log(`Signature: ${tx.signature}`);
    console.log(`Error: ${tx.error}`);
    console.log(`Fee Paid: ${tx.fee} SOL`);
  });

  return failed;
};
```

### Reconstruct a historical balance

Calculate what the balance was at a specific point in time:

```javascript theme={"system"}
const getHistoricalBalance = async (address, targetTimestamp) => {
  const transactions = await getAllTransactionHistory(address);

  // Filter to transactions before target date
  const relevantTxs = transactions.filter(tx => tx.timestamp <= targetTimestamp);

  // Sum all balance changes
  const balances = {};

  relevantTxs.forEach(tx => {
    tx.balanceChanges.forEach(change => {
      if (!balances[change.mint]) {
        balances[change.mint] = 0;
      }
      balances[change.mint] += change.amount;
    });
  });

  console.log(`Historical balances as of ${new Date(targetTimestamp * 1000).toLocaleString()}:`);
  Object.entries(balances).forEach(([mint, balance]) => {
    console.log(`${mint}: ${balance}`);
  });

  return balances;
};

// Example: Get balances on Jan 1, 2024
getHistoricalBalance(
  "86xCnPeV69n6t3DnyGvkKobf9FdN2H9oiVDdaMpo2MMY",
  new Date("2024-01-01").getTime() / 1000
);
```

For a single token's exact balance at a point in time, the [Historical Balance](/wallet-api/balance-at) endpoint reads it directly from on-chain post-balances instead of summing changes client-side.

### Analyze transaction fees

Calculate total fees paid:

```javascript theme={"system"}
const analyzeFees = async (address) => {
  const transactions = await getAllTransactionHistory(address);

  const totalFees = transactions.reduce((sum, tx) => sum + tx.fee, 0);
  const avgFee = totalFees / transactions.length;

  const successfulTxs = transactions.filter(tx => !tx.error);
  const failedTxs = transactions.filter(tx => tx.error);

  const wastedFees = failedTxs.reduce((sum, tx) => sum + tx.fee, 0);

  console.log(`Total Transactions: ${transactions.length}`);
  console.log(`Successful: ${successfulTxs.length}`);
  console.log(`Failed: ${failedTxs.length}`);
  console.log(`Total Fees Paid: ${totalFees.toFixed(6)} SOL`);
  console.log(`Average Fee: ${avgFee.toFixed(6)} SOL`);
  console.log(`Wasted on Failed Txs: ${wastedFees.toFixed(6)} SOL`);

  return {
    totalFees,
    avgFee,
    wastedFees,
    successRate: (successfulTxs.length / transactions.length) * 100
  };
};
```

## Best practices

* **Use pagination for complete history.** Some wallets have hundreds of thousands of transactions; always paginate when fetching all of them.
* **Cache historical data.** Historical transactions never change. Cache them locally and only fetch new transactions.
* **Handle failed transactions.** Check the `error` field to distinguish successful from failed transactions. Failed transactions still incur fees.
* **Use timestamps for date filtering.** Timestamps are in Unix seconds. Convert to local dates for display and filtering.
