Unstable Method

This subscription is considered unstable and is only available if the validator was started with the --rpc-pubsub-enable-block-subscription flag. Формат этой подписки может измениться в будущем.

Parameters #

filter string | object required

фильтровать критерии для получения результатов по типу учетной записи; в настоящее время поддерживается:

string

all - include all transactions in block

object

A JSON object with the following field:

mentionsAccountOrProgram: <string> - return only transactions that mention the provided public key (as base-58 encoded string). If no mentions in a given block, then no notification will be sent.

object optional

Configuration object containing the following fields:

commitment string optional

Default: finalized

processed is not supported.

encoding string optional

Default: json

encoding format for each returned Transaction

Values: jsonjsonParsedbase58base64

jsonParsed attempts to use program-specific instruction parsers to return more human-readable and explicit data in the transaction.message.instructions list.
If jsonParsed is requested but a parser cannot be found, the instruction falls back to regular JSON encoding (accounts, data, and programIdIndex fields).

transactionDetails string optional

Default: full

уровень детализации транзакции для возврата

Values: fullaccountssignaturesnone

If accounts are requested, transaction details only include signatures and an annotated list of accounts in each transaction.
Transaction metadata is limited to only: fee, err, pre_balances, post_balances, pre_token_balances, and post_token_balances.

maxSupportedTransactionVersion number optional

максимальная версия транзакции, которую следует возвращать в ответах.

If the requested block contains a transaction with a higher version, an error will be returned.
If this parameter is omitted, only legacy transactions will be returned, and a block containing any versioned transaction will prompt the error.

showRewards bool optional

whether to populate the rewards array. If parameter not provided, the default includes rewards.
