||
| ## Structures | ||
|
|
||
| ### ExitV1 | ||
|
|
||
| This structure represents an execution layer triggered exit operation. | ||
| The fields are encoded as follows: | ||
|
|
||
| - `sourceAddress`: `DATA`, 20 Bytes | ||
| - `validatorPublicKey`: `DATA`, 48 Bytes | ||
|
|
||
| ### ExecutionPayloadV4 | ||
|
|
||
| This structure has the syntax of [`ExecutionPayloadV3`](./cancun.md#executionpayloadv3) and appends the new field: `exits`. | ||
|
|
||
| - `parentHash`: `DATA`, 32 Bytes | ||
| - `feeRecipient`: `DATA`, 20 Bytes | ||
| - `stateRoot`: `DATA`, 32 Bytes | ||
| - `receiptsRoot`: `DATA`, 32 Bytes | ||
| - `logsBloom`: `DATA`, 256 Bytes | ||
| - `prevRandao`: `DATA`, 32 Bytes | ||
| - `blockNumber`: `QUANTITY`, 64 Bits | ||
| - `gasLimit`: `QUANTITY`, 64 Bits | ||
| - `gasUsed`: `QUANTITY`, 64 Bits | ||
| - `timestamp`: `QUANTITY`, 64 Bits | ||
| - `extraData`: `DATA`, 0 to 32 Bytes | ||
| - `baseFeePerGas`: `QUANTITY`, 256 Bits | ||
| - `blockHash`: `DATA`, 32 Bytes | ||
| - `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) | ||
| - `withdrawals`: `Array of WithdrawalV1` - Array of withdrawals, each object is an `OBJECT` containing the fields of a `WithdrawalV1` structure. | ||
| - `blobGasUsed`: `QUANTITY`, 64 Bits | ||
| - `excessBlobGas`: `QUANTITY`, 64 Bits | ||
| - `exits`: `Array of ExitV1` - Array of exits, each object is an `OBJECT` containing the fields of a `ExitV1` structure. | ||
|
|
||
| ## Methods | ||
|
|
||
| ### engine_newPayloadV4 | ||
|
|
||
| The request of this method is updated with [`ExecutionPayloadV4`](#ExecutionPayloadV4). | ||
|
|
||
| #### Request | ||
|
|
||
| * method: `engine_newPayloadV4` | ||
| * params: | ||
| 1. `executionPayload`: [`ExecutionPayloadV4`](#ExecutionPayloadV4). | ||
| 2. `expectedBlobVersionedHashes`: `Array of DATA`, 32 Bytes - Array of expected blob versioned hashes to validate. | ||
| 3. `parentBeaconBlockRoot`: `DATA`, 32 Bytes - Root of the parent beacon block. | ||
|
|
||
| #### Response | ||
|
|
||
| Refer to the response for [`engine_newPayloadV3`](./cancun.md#engine_newpayloadv3). | ||
|
|
||
| #### Specification | ||
|
|
||
| This method follows the same specification as [`engine_newPayloadV3`](./cancun.md#engine_newpayloadv3). | ||
|
|
||
| ### engine_getPayloadV4 | ||
|
|
||
| The response of this method is updated with [`ExecutionPayloadV4`](#ExecutionPayloadV4). | ||
|
|
||
| #### Request | ||
|
|
||
| * method: `engine_getPayloadV4` | ||
| * params: | ||
| 1. `payloadId`: `DATA`, 8 Bytes - Identifier of the payload build process | ||
| * timeout: 1s | ||
|
|
||
| #### Response | ||
|
|
||
| * result: `object` | ||
| - `executionPayload`: [`ExecutionPayloadV4`](#ExecutionPayloadV4) | ||
| - `blockValue` : `QUANTITY`, 256 Bits - The expected value to be received by the `feeRecipient` in wei | ||
| - `blobsBundle`: [`BlobsBundleV1`](#BlobsBundleV1) - Bundle with data corresponding to blob transactions included into `executionPayload` | ||
| - `shouldOverrideBuilder` : `BOOLEAN` - Suggestion from the execution layer to use this `executionPayload` instead of an externally provided one | ||
| * error: code and message set in case an exception happens while getting the payload. | ||
|
|
||
| #### Specification | ||
|
|
||
| Refer to the specification for [`engine_getPayloadV3`](./cancun.md#engine_getpayloadv3). |
