​
Overview

  • Dataset ID: 0121 - Contracts
  • Description: Smart contracts discovered via CREATE/CREATE2 internal transactions. Uses contract_id (26 bytes = address + creation_block + tx_index) as primary key to support metamorphic contracts (e.g. CREATE–SELFDESTRUCT–CREATE2 in the same block).
  • Sample: Hugging Face Sample

​
Parameters

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

​
Range Filters (mutually exclusive with direct selectors)

​
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, a time range, block_numbers, or contract_addresses.
Providing both range selectors and explicit selectors results in HTTP 400.
Providing none also results in HTTP 400.

​
Direct Selectors

​
contract_addresses
string[]
Filter by specific deployed contract addresses (hex string, 20 bytes, no 0x prefix). Up to 256 addresses per request.
​
block_numbers
number[]
Explicit list of block heights to fetch contract deployments from. Mutually exclusive with the range filters.

​
Pagination Controls

​
limit
number
default:"250"
Recommended default 250; maximum 1000 to stay under ~10 MB responses.
​
cursor
string
Opaque pagination cursor supplied by a previous response.

​
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
Block/timestamp bounds derived from the request.
​
meta.filters
object
Filters echoed from the request (contract addresses, block numbers, limit).

​
Data

​
data
object[]
Each element mirrors the table columns (chain implied by meta.chain_id).
​
data.chain_id
number
EVM Chain ID for the record.
​
data.contract_id
string
Unique contract incarnation ID (hex string, 26 bytes, no 0x prefix): 20 bytes address + 4 bytes creation block + 2 bytes tx_index. Use for metamorphic disambiguation and to join with function-results.
​
data.contract_address
string
Deployed contract address (hex string, 20 bytes, no 0x prefix). Use for address-based lookups.
​
data.block_number
number
Block height containing the contract creation.
​
data.block_time
string
ISO-8601 UTC timestamp of the creation block, joined from the blocks dataset.
​
data.tx_index
number
Zero-based index of the deployment transaction within the block.
​
data.trace_address
string
Position in the call tree (e.g., "0", "0.0", "0.1.2").
​
data.creator_address
string
Address that deployed the contract (msg.sender of CREATE/CREATE2). Hex string, 20 bytes, no 0x prefix.
​
data.creation_call_type
string
Type of creation: CREATE or CREATE2.
​
data._tracing_id
string
Internal tracing identifier for lineage tracking (hex string, no 0x prefix).
​
data._created_at
string
Timestamp when BlockDB materialized the record.
​
data._updated_at
string
Timestamp of the latest update to the record.

​
Envelope Fields

​
cursor
string | null
Pagination cursor to continue the query.
​
count
number
Number of records in the current page.

​
Use Cases

  • Look up the canonical creation block for a contract address before hydrating additional metadata.
  • Backfill on-chain analyses that require the deployment timestamp or transaction location.
  • Seed lineage exploration using _tracing_id to pivot into /evm/logs and /evm/transactions.
