Overview

The SubscribeRequest message is used to initiate a subscription to the Yellowstone gRPC stream. It allows you to define multiple filters for different types of updates (accounts, transactions, blocks, slots) and specify subscription parameters.

​
Message Definition

message SubscribeRequest {
  map<string, SubscribeRequestFilterAccounts> accounts = 1;
  map<string, SubscribeRequestFilterSlots> slots = 2;
  map<string, SubscribeRequestFilterTransactions> transactions = 3;
  map<string, SubscribeRequestFilterTransactions> transactions_status = 10;
  map<string, SubscribeRequestFilterBlocks> blocks = 4;
  map<string, SubscribeRequestFilterBlocksMeta> blocks_meta = 5;
  map<string, SubscribeRequestFilterEntry> entry = 8;
  optional CommitmentLevel commitment = 6;
  repeated SubscribeRequestAccountsDataSlice accounts_data_slice = 7;
  optional SubscribeRequestPing ping = 9;
  optional uint64 from_slot = 11;
}

Fields

​
accounts
map<string, SubscribeRequestFilterAccounts>
Map of named account filters. The key is a user-defined filter name, and the value specifies the account filter criteria. See Filter Messages for details.
​
slots
map<string, SubscribeRequestFilterSlots>
Map of named slot filters. The key is a user-defined filter name, and the value specifies the slot filter criteria. See Filter Messages for details.
​
transactions
map<string, SubscribeRequestFilterTransactions>
Map of named transaction filters for confirmed/finalized transactions. The key is a user-defined filter name, and the value specifies the transaction filter criteria. See Filter Messages for details.
​
transactions_status
map<string, SubscribeRequestFilterTransactions>
Map of named transaction status filters for early transaction status updates. Uses the same filter type as transactions but provides updates as soon as the transaction is received, before full execution details are available.
​
blocks
map<string, SubscribeRequestFilterBlocks>
Map of named block filters. The key is a user-defined filter name, and the value specifies the block filter criteria. See Filter Messages for details.
​
blocks_meta
map<string, SubscribeRequestFilterBlocksMeta>
Map of named block metadata filters. Block meta updates contain only block metadata without full transaction or account data, reducing bandwidth. Currently accepts an empty filter object.
​
entry
map<string, SubscribeRequestFilterEntry>
Map of named entry filters. Entries represent Proof of History entries. Currently accepts an empty filter object.
​
commitment
CommitmentLevel
Optional commitment level for the subscription. Determines when updates are sent based on confirmation status.
​
accounts_data_slice
repeated SubscribeRequestAccountsDataSlice
Optional array of data slices to request only portions of account data, reducing bandwidth. Each slice specifies an offset and length.
​
ping
SubscribeRequestPing
Optional ping configuration for keepalive messages.
​
from_slot
uint64
Optional starting slot number. If specified, the subscription will begin sending updates from this slot onwards. Useful for replaying historical data or resuming from a known slot.
