​
Description

Retrieves native network token (e.g. ETH on Ethereum) transfer events only: transaction value (native_tx) and internal transfers (native_internal). Use this endpoint when you need only native flows, without ERC-20, ERC-721, or ERC-1155.

​
Parameters

​
chain_id
number
required
Target EVM network. See the Chain enumeration for supported values.

​
Range Filters (mutually exclusive)

​
from_block
number
Starting block number (inclusive) for the query. Use with to_block.
​
to_block
number
Ending block number (inclusive) for the query. Use with from_block.
​
from_timestamp
string
Starting timestamp (ISO-8601). If it falls between blocks, the next block after this timestamp is used. Use with to_timestamp.
​
to_timestamp
string
Ending timestamp (ISO-8601). If it falls between blocks, the last block before this timestamp is used. Use with from_timestamp.
Validation rule:
You must provide either a block range or a time range.
Providing both results in HTTP 400.
Providing none results in HTTP 400.

​
Optional Filters

​
from_address
string
Filter by sender address (hex string, 20 bytes, no 0x prefix).
​
to_address
string
Filter by recipient address (hex string, 20 bytes, no 0x prefix).

​
Pagination Controls

​
limit
number
default:"250"
Recommended default 250; maximum 1000 to stay under ~10 MB responses.
​
cursor
string
Pagination cursor from a prior call.

​
Response Fields

​
Meta

​
meta
object
Echo of request metadata applied to the response.
​
meta.chain_id
number
EVM chain ID echoed from the request.
​
meta.request_window
object
Normalized block/timestamp bounds derived from the request.
​
meta.filters
object
Filter parameters echoed from the request (addresses, pagination state, etc.).

​
Data

​
data
object[]
Array of token transfer records, ordered by block and position.
​
data.id
number
Surrogate primary key for the transfer record (auto-generated).
​
data.chain_id
number
Chain ID for the transfer record.
​
data.block_number
number
Block where the transfer occurred.
​
data.block_time
string
UTC timestamp of the block (ISO-8601).
​
data.tx_index
number
Transaction index within the block.
​
data.log_index
number | null
Log index within the transaction receipt; null for native or internal tx transfers.
​
data.trace_address
string | null
Trace address for internal tx transfers (e.g. "0", "0.1"); null for log-based transfers.
​
data.from_address
string
Sender address (hex string, 20 bytes, no 0x prefix).
​
data.to_address
string
Recipient address (hex string, 20 bytes, no 0x prefix).
​
data.token_address
string | null
Token contract address (hex string, 20 bytes); null for native ETH.
​
data.amount_raw
string
Raw amount in smallest unit (wei for native, raw uint256 for ERC-20/1155). String to preserve precision.
​
data.amount_adj
string | null
Decimal-adjusted amount; null if decimals unknown or NFT (ERC-721).
​
data.token_id
string | null
Token ID for ERC-721 and ERC-1155; null for native/ERC-20. String to preserve precision.
​
data.transfer_type
string
Either native_tx (transaction value) or native_internal (internal transfer) for this endpoint.
​
data._tracing_id
string
BlockDB lineage identifier (hex string, no 0x prefix).
​
data._parent_tracing_ids
string[]
BlockDB lineage identifiers of the parent records.
​
data._created_at
string
Record creation timestamp, e.g. "2025-11-11T18:42:15.123Z".
​
data._updated_at
string
Last update timestamp in the same format.

​
Envelope Fields

​
cursor
string | null
Cursor token for pagination.
​
count
number
Number of records returned in data.
