Attributes used to guide the construction of a new execution payload.

Extends basic payload attributes with additional context needed during the building process, tracking in-progress payload jobs and their parameters.

Required Associated Types

type RpcPayloadAttributes: Send + Sync + 'static

The external payload attributes format this type can be constructed from.

type Error: Error + Send + Sync + 'static

The error type used in PayloadBuilderAttributes::try_new.

Required Methods

fn try_new( parent: FixedBytes<32>, rpc_payload_attributes: Self::RpcPayloadAttributes, version: u8, ) -> Result<Self, Self::Error>

where Self: Sized,

Constructs new builder attributes from external payload attributes.

Validates attributes and generates a unique [PayloadId] based on the parent block, attributes, and version.

fn payload_id(&self) -> PayloadId

Returns the unique identifier for this payload build job.

fn parent(&self) -> FixedBytes<32>

Returns the hash of the parent block this payload builds on.

fn timestamp(&self) -> u64

Returns the timestamp to be used in the payload’s header.

fn parent_beacon_block_root(&self) -> Option<FixedBytes<32>>

Returns the beacon chain block root from the parent block.

Returns None for pre-merge blocks or non-beacon contexts.

fn suggested_fee_recipient(&self) -> Address

Returns the address that should receive transaction fees.

fn prev_randao(&self) -> FixedBytes<32>

Returns the randomness value for this block.

fn withdrawals(&self) -> &Withdrawals

Returns the list of withdrawals to be processed in this block.
