    blobGasPrice: true,        // Blob gas price paid (type-3)
  }
}
```

### Log Fields

Select event log fields:

```typescript theme={"system"}
fields: {
  log: {
    address: true,         // Contract address
    topics: true,          // Event topics (topic0-topic3)
    data: true,            // Event data
    logIndex: true,        // Log index in block
    transactionIndex: true,// Transaction index
    transactionHash: true, // Transaction hash
  }
}
```

### Trace Fields

Select call trace fields. The selectors are prefixed by trace kind (`call*`, `create*`, `suicide*`, `reward*`); there are no bare `from`/`to`/`value` selectors:

```typescript theme={"system"}
fields: {
  trace: {
    type: true,                // Trace type: "call" or "create"
    transactionIndex: true,    // Index of the parent transaction in the block
    error: true,               // Error message (if failed)
    revertReason: true,        // Revert reason (if reverted)
    // call traces
    callFrom: true,            // Caller address
    callTo: true,              // Callee address
    callValue: true,           // Value transferred (hex wei)
    callGas: true,             // Gas provided
    callSighash: true,         // Function selector (first 4 bytes)
    callInput: true,           // Call input data
    callResultGasUsed: true,   // Gas actually used
    callResultOutput: true,    // Call output data
    // create traces
    createFrom: true,          // Deployer address
    createValue: true,         // Value sent with deployment (hex wei)
    createResultAddress: true, // Created contract address
    createResultCode: true,    // Created contract code
  }
}
```

<Note>
  **The response nests these fields, and `transactionHash` is not a trace field.**

  * Requested `call*`/`create*` selectors come back grouped under `action` and `result` sub-objects, not flat. For example `callFrom`/`callTo`/`callValue` are returned as `action.{from,to,value}`, and `callResultGasUsed` as `result.gasUsed`. Numeric values such as `action.value` are **hex wei** (e.g. `"0x0"`).
  * `transactionHash` is not a valid `fields.trace.*` selector. To get a trace's transaction hash, join the parent transaction: set `"transaction": true` in the traces filter and request `fields.transaction.hash`.
  * The `@subsquid/portal-client` typed client keeps the same `action`/`result` nesting; access `trace.action.from` and `trace.result?.gasUsed` rather than `trace.callFrom`/`trace.callResultGasUsed`.
</Note>

### State Diff Fields

Select state change fields:

```typescript theme={"system"}
fields: {
  stateDiff: {
    address: true,         // Contract address
    key: true,             // Storage key
    kind: true,            // Change type (=, +, *, -)
    prev: true,            // Previous value
    next: true,            // New value
  }
}
```

## Filtering Options

### Log Filters

Filter logs by contract address and event topics:

```typescript theme={"system"}
logs: [
  {
    address: ["0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48"], // USDC
    topic0: [
      "0xddf252ad1be2c89b69c2b068fc378daa952ba7f163c4a11628f55a4df523b3ef",
    ], // Transfer
    topic1: ["0x..."], // Optional: first indexed param
    topic2: ["0x..."], // Optional: second indexed param
    topic3: ["0x..."], // Optional: third indexed param
  },
  // Multiple filter objects = OR logic
  {
    address: ["0x..."],
    topic0: ["0x..."],
  },
];
```

**Filter logic:**

* Multiple addresses in one object = OR
* Multiple topics in one object = AND
* Multiple filter objects = OR

### Transaction Filters

Filter transactions by sender, recipient, or function signature:

```typescript theme={"system"}
transactions: [
  {
    from: ["0x..."], // Sender addresses
    to: ["0x..."], // Recipient addresses
    sighash: ["0xa9059cbb"], // Function signature (first 4 bytes)
  },
];
```

### Trace Filters

Filter traces by type, caller, or callee:

```typescript theme={"system"}
traces: [
  {
    type: ["call", "delegatecall", "staticcall"],
    callFrom: ["0x..."], // Caller address
    callTo: ["0x..."], // Callee address
    callSighash: ["0x..."], // Function signature
  },
];
```

### State Diff Filters

Filter state changes by contract address:

```typescript theme={"system"}
stateDiffs: [
  {
    address: ["0x..."], // Contract addresses
  },
];
```

## Network Selection

Specify the EVM network in the dataset URL when creating the client:

```typescript theme={"system"}
// Ethereum mainnet
const eth = new PortalClient({ url: "https://portal.sqd.dev/datasets/ethereum-mainnet" });

// Ethereum testnet
const sepolia = new PortalClient({ url: "https://portal.sqd.dev/datasets/ethereum-sepolia" });

// Layer 2 networks
const arbitrum = new PortalClient({ url: "https://portal.sqd.dev/datasets/arbitrum-one" });
const optimism = new PortalClient({ url: "https://portal.sqd.dev/datasets/optimism-mainnet" });
const base = new PortalClient({ url: "https://portal.sqd.dev/datasets/base-mainnet" });
const polygon = new PortalClient({ url: "https://portal.sqd.dev/datasets/polygon-mainnet" });

// Other EVM chains
const bsc = new PortalClient({ url: "https://portal.sqd.dev/datasets/binance-mainnet" });
const avalanche = new PortalClient({ url: "https://portal.sqd.dev/datasets/avalanche-mainnet" });
```

## Query Patterns

### Pattern 1: Range Query

Query a specific block range:

```typescript theme={"system"}
for await (const { blocks } of client.getStream({
  type: "evm",
  fromBlock: 18000000,
  toBlock: 18100000,
  fields: {
    /* fields */
  },
  logs: [
    /* filters */
  ],
})) {
  /* process blocks */
}
```

### Pattern 2: Batch Processing

`getStream` already paginates the range internally and yields one batch of blocks per iteration, so there is no need to split the range into fixed-size queries yourself:

```typescript theme={"system"}
for await (const { blocks } of client.getStream({
  type: "evm",
  fromBlock: startBlock,
  toBlock: endBlock,
  fields: {
    /* fields */
  },
})) {
  // Each iteration yields one batch of blocks
  await processBlocks(blocks);
}
```

### Pattern 3: Multi-Contract Query

Query multiple contracts simultaneously:

```typescript theme={"system"}
for await (const { blocks } of client.getStream({
  type: "evm",
  fromBlock: 18000000,
  toBlock: 18100000,
  fields: {
    log: { address: true, topics: true, data: true },
  },
  logs: [
    {
      address: [
        "0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48", // USDC
        "0xdAC17F958D2ee523a2206206994597C13D831ec7", // USDT
        "0x6B175474E89094C44Da98b954EedeAC495271d0F", // DAI
      ],
      topic0: [
        "0xddf252ad1be2c89b69c2b068fc378daa952ba7f163c4a11628f55a4df523b3ef",
      ],
    },
  ],
})) {
  /* process blocks */
}
```

## Performance Optimization

### 1. Request Only Needed Fields

```typescript theme={"system"}
// Good: Minimal fields
fields: {
  log: {
    address: true,
    topics: true,
  }
}

// Avoid: Requesting unnecessary fields
fields: {
  log: {
    address: true,
    topics: true,
    data: true,        // Only if needed
    transactionHash: true, // Only if needed
    blockNumber: true,     // Only if needed
  }
}
```

### 2. Use Specific Filters

```typescript theme={"system"}
// Good: Filter at Portal level
logs: [
  {
    address: ["0xSpecificContract"],
    topic0: ["0xSpecificEvent"],
  },
];

// Avoid: Fetching everything and filtering in code
logs: []; // Gets all logs
```

### 3. Optimal Batch Sizes

```typescript theme={"system"}
// Good: 10k-50k blocks per query for most use cases
const BATCH_SIZE = 10000;

// Adjust based on:
// - More filters = larger batches OK
// - More fields = smaller batches
// - More activity (mainnet) = smaller batches
```

### 4. Parallel Queries

```typescript theme={"system"}
// Process multiple ranges in parallel
const ranges = [
  { fromBlock: 18000000, toBlock: 18100000 },
  { fromBlock: 18100000, toBlock: 18200000 },
  { fromBlock: 18200000, toBlock: 18300000 },
] as const;

const results = await Promise.all(
  ranges.map(async (range) => {
    const blocks = [];
    for await (const { blocks: batch } of client.getStream({
      type: "evm",
      ...range,
      fields: {
        /* fields */
      },
    })) {
      blocks.push(...batch);
    }
    return blocks;
  })
);
```

## Resolve a timestamp to a block

`GET /datasets/{dataset}/timestamps/{timestamp}/block` returns the number of the first block whose timestamp is greater than or equal to the given Unix timestamp (in seconds). Use it to turn a wall-clock time into a `fromBlock` for a stream query.

```bash theme={"system"}
curl 'https://portal.sqd.dev/datasets/ethereum-mainnet/timestamps/1693066895/block'
```

```json theme={"system"}
{ "block_number": 18000000 }
```

Resolution prefers archival data and falls back to the real-time source when available; the `x-sqd-data-source` response header reports which one served the result (`network` or `real_time`). The endpoint returns `404` if no block at or after the timestamp exists yet.

## Stream continuation

A single `/stream` response is a **batch**, not the complete range. The server may close the connection at any point: when a worker's range ends, when a connection is recycled, or at the current dataset head. Clients that treat one HTTP response as the whole query will silently drop blocks.

To stream a range to completion, loop:

```typescript theme={"system"}
async function streamRange(from: number, to: number | undefined, body: any) {
  let currentFrom = from;
  while (to === undefined || currentFrom <= to) {
    const res = await fetch(
      "https://portal.sqd.dev/datasets/ethereum-mainnet/stream",
      {
        method: "POST",
        headers: { "Content-Type": "application/json" },
        body: JSON.stringify({ ...body, fromBlock: currentFrom, toBlock: to }),
      }
    );

    if (res.status === 204) break; // range is above the dataset head
    if (!res.ok) throw new Error(`HTTP ${res.status}: ${await res.text()}`);

    const lines = (await res.text()).trim().split("\n").filter(Boolean);
    if (lines.length === 0) break;

    let lastBlock = currentFrom - 1;
    for (const line of lines) {
      const block = JSON.parse(line);
      // ... process block ...
      lastBlock = block.header.number;
    }
    currentFrom = lastBlock + 1;
  }
}
```

Key points:

* Read the last block's `header.number`, issue the next request with `fromBlock = lastNumber + 1`.
* Keep `toBlock`, `fields`, and filters identical across retries.
* A `204 No Content` response means the range is above the dataset head. For historical queries, you're done; for open-ended queries, wait and retry.

## Handling reorgs near the chain head

When a request starts at or near the chain tip, the block you asked for may no longer be on the canonical chain by the time Portal processes the query. To detect this, pass `parentBlockHash` with each request (the hash of the block immediately before `fromBlock`):

```typescript theme={"system"}
const body = {
  type: "evm",
  fromBlock: lastBlock.number + 1,
  parentBlockHash: lastBlock.hash, // hash of lastBlock, i.e. parent of fromBlock
  fields: { block: { number: true, hash: true, parentHash: true } },
  logs: [
    /* filters */
  ],
};
```

If the chain has reorged away from `parentBlockHash`, Portal returns **HTTP 409** with the `base_block_mismatch` error and a list of blocks that **are** on the current canonical chain:

```json theme={"system"}
{
  "error": {
    "type": "invalid_request_error",
    "code": "base_block_mismatch",
    "message": "Base block mismatch"
  },
  "previousBlocks": [
    { "number": 24928290, "hash": "0x8af2be..." },
    { "number": 24928291, "hash": "0x129bc9..." }
  ]
}
```

`previousBlocks` sits at the top level, beside `error`. It is ordered ascending (the last entry is the most recent block) and always contains at least the parent of the requested `fromBlock`.

Client recovery:

1. Find a block in your local state whose `(number, hash)` matches one of `previousBlocks`.
2. Roll back your pipeline to that block.
3. Resume the stream with `fromBlock = matched.number + 1` and `parentBlockHash = matched.hash`.
4. If nothing in `previousBlocks` matches your records, the divergence is deeper than the returned slice: open a new stream with an earlier `fromBlock` (again passing `parentBlockHash`) and repeat the search.

Prefer `/finalized-stream` (instead of `/stream`) when you don't need real-time data: finalized history does not reorganize, so there are no new forks to handle. A 409 can still occur there when the `parentBlockHash` you pass is stale, for example carried over from an orphaned unfinalized block; recover the same way.

## Error Handling

Every Portal error response, on any endpoint, is a JSON envelope with a machine-readable `type` and `code`:

```json theme={"system"}
{
  "error": {
    "type": "availability_error",
    "code": "no_workers",
    "message": "No workers available for dataset"
  }
}
```

Branch on `error.type`, and match on `error.code` when you handle one specific case. `error.message` is human-readable prose that can change at any time; never parse or match on it.

| `error.type` | What to do |
| - | - |
| `invalid_request_error` | Do not retry: the same request fails the same way. Fix the request. HTTP 409 (`base_block_mismatch`) is the reorg signal covered in [Handling reorgs near the chain head](#handling-reorgs-near-the-chain-head). |
| `rate_limit_error` | Retry after the interval in the `Retry-After` header. It is always present on these responses and counts seconds. |
| `availability_error` | A transient Portal or upstream condition. Retry with backoff, honoring `Retry-After` when present. |
| `api_error` | A Portal bug. Do not retry; report the error together with its `request_id` (also sent as the `x-request-id` response header). |

A `204 No Content` response is not an error: the requested range simply has no blocks yet (see [Stream continuation](#stream-continuation)).

The full contract, including every `error.code` and its HTTP status, is in [Portal error handling](/en/portal/introduction/error-handling).

## Common Use Cases

### Use Case 1: Event Monitoring

Monitor specific smart contract events:

```typescript theme={"system"}
for await (const { blocks } of client.getStream({
  type: "evm",
  fromBlock: latestProcessedBlock + 1,
  fields: {
    block: { timestamp: true },
    log: { address: true, topics: true, data: true },
  },
  logs: [
    {
      address: [CONTRACT_ADDRESS],
      topic0: [EVENT_SIGNATURE],
    },
  ],
})) {
  /* process blocks */
}
```

### Use Case 2: Transaction Tracking

Track transactions to/from specific addresses:

```typescript theme={"system"}
for await (const { blocks } of client.getStream({
  type: "evm",
  fromBlock: startBlock,
  toBlock: endBlock,
  fields: {
    transaction: { hash: true, from: true, to: true, value: true },
  },
  transactions: [
    {
      from: [WATCHED_ADDRESS],
    },
  ],
})) {
  /* process blocks */
}
```

### Use Case 3: Analytics Pipeline

Build analytics on blockchain data:

```typescript theme={"system"}
const stats: { block: number; txCount: number; totalGas: bigint; totalValue: bigint }[] = [];

for await (const { blocks } of client.getStream({
  type: "evm",
  fromBlock: startBlock,
  toBlock: endBlock,
  fields: {
    block: { gasUsed: true },
    transaction: { gasUsed: true, value: true },
  },
})) {
  // Aggregate statistics
  for (const block of blocks) {
    stats.push({
      block: block.header.number,
      txCount: block.transactions.length,
      totalGas: block.header.gasUsed,
      totalValue: block.transactions.reduce((sum, tx) => sum + tx.value, 0n),
    });
  }
}
```

## Request Structure Reference

Every Portal request follows this structure:

```typescript theme={"system"}
{
  type: "evm",              // Chain type
  fromBlock: number,        // Starting block (inclusive)
  toBlock?: number,         // Ending block (inclusive, optional)
  fields: {                 // What data to return
    block?: { ... },
    transaction?: { ... },
    log?: { ... },
    trace?: { ... },
    stateDiff?: { ... }
  },
  logs?: [...],            // Filter by event logs
  transactions?: [...],    // Filter by transactions
  traces?: [...],          // Filter by call traces
  stateDiffs?: [...]       // Filter by state changes
}
```

## Response Format

Portal returns **newline-delimited JSON (NDJSON)**, with one block per line:

```json theme={"system"}
{"header": {"number": 18000000, ...}, "logs": [...], "transactions": [...]}
{"header": {"number": 18000001, ...}, "logs": [...], "transactions": [...]}
{"header": {"number": 18000002, ...}, "logs": [...], "transactions": [...]}
```

This format enables constant-memory streaming of arbitrary ranges.

## Common Patterns

<AccordionGroup>
  <Accordion title="Batch Processing">
    Process large block ranges by splitting into manageable chunks:

    ```typescript theme={"system"}
    const BATCH_SIZE = 10000;
    for (let from = startBlock; from < endBlock; from += BATCH_SIZE) {
      const to = Math.min(from + BATCH_SIZE, endBlock);
      const blocks = await fetch(/* ... */);
    }
    ```
  </Accordion>

  <Accordion title="Real-time Streaming">
    Stream new blocks as they arrive using /finalized-stream:

    ```typescript theme={"system"}
    const response = await fetch(
      'https://portal.sqd.dev/datasets/ethereum-mainnet/finalized-stream',
      { method: 'POST', body: JSON.stringify({
        type: 'evm',
        fromBlock: latestProcessedBlock + 1,
        fields: { /* ... */ }
      })}
    );
    ```
  </Accordion>

  <Accordion title="Error Handling">
    Handle rate limits and network errors gracefully:

    ```typescript theme={"system"}
    try {
      const response = await fetch(/* ... */);
      if (!response.ok) {
        if (response.status === 429) {
          // Rate limited - wait and retry
          await sleep(10000);
        }
      }
    } catch (error) {
      // Network error - implement retry logic
    }
    ```
  </Accordion>
</AccordionGroup>
