-## Structures
-
-### InclusionListV1
-
-This structure contains a list of transactions. The fields are encoded as follows:
-- `transactions`: `Array of DATA` - Array of transaction objects, each object is a byte list (`DATA`) representing `TransactionType || TransactionPayload` or `LegacyTransaction` as defined in [EIP-2718](https://eips.ethereum.org/EIPS/eip-2718)
-
-### UpdateInclusionListResponse
-
-This structure contains an identifier of the payload build process that is requested to update with the given inclusion list.
-- `payloadId`: `DATA`, 8 Bytes - Identifier of the payload build process
-
