Unified Confirmed Transaction Trace

This event is triggered when:

A new transaction is confirmed and traced within the Ethereum blockchain.
The trace captures detailed execution information, including internal calls, gas usage, and input/output data.

📘
Note
Each call within a transaction trace is flattened and delivered as an individual message if it matches the filter criteria.

Field	Type	Description
`tx_id`	string	(Required) The transaction identifier, such as the transaction hash or other unique identifier.
`tx_hash`	string	The transaction hash.
`timestamp`	integer	(Required) The UNIX timestamp when the block was mined/validated.
`block_hash`	string	(Required) The block hash.
`block_number`	integer	(Required) The block number.
`type`	string	The type of call (e.g. `CALL`, `DELEGATECALL`, `STATICCALL`).
`from`	string	The sender's account address.
`to`	string	The recipient's account address.
`value`	string	The value transferred, in the lowest denomination of the asset (e.g. wei for ETH).
`gas`	string	The gas limit set for this call.
`gas_used`	string	The actual amount of gas used for the call.
`input`	string	The data sent with the call.
`output`	string	The data returned by the call, if any.
`calls`	array	Nested internal calls made by this call, if any. See the note above.

This schema applies to the UNIFIED_V1 and UNIFIED_V1_RAW templates. ALL_DATA returns the chain's native trace payload unmodified, with its own fields, shown below per protocol.

Examples

Base

MainnetSepolia

Base is an Ethereum L2 and is EVM-compatible, so its trace payload follows the same call-tree shape as Ethereum. This example is a single DELEGATECALL with no internal sub-calls, so calls is empty.
