# Message Type

## Response Wrappers

### StreamResponse

Standard response for EventPublisher methods.

```protobuf
message StreamResponse {
  bytes data = 1;  // Serialized event data
}
```

### MessageWrapper

Unified wrapper for ThorStreamer service containing typed events.

```protobuf
message MessageWrapper {
  oneof event_message {
    SubscribeUpdateAccountInfo account_update = 1;
    SlotStatusEvent slot = 2;
    TransactionEventWrapper transaction = 3;
  }
}
```

***

## Transaction Events

### TransactionEventWrapper

```protobuf
message TransactionEventWrapper {
  StreamType stream_type = 1;
  TransactionEvent transaction = 2;
}

enum StreamType {
  STREAM_TYPE_UNSPECIFIED = 0;
  STREAM_TYPE_FILTERED = 1;    // From program filters
  STREAM_TYPE_WALLET = 2;      // From wallet subscription
  STREAM_TYPE_ACCOUNT = 3;     // From account subscription
}
```

### TransactionEvent

```protobuf
message TransactionEvent {
  uint64 slot = 1;                    // Slot number
  bytes signature = 2;                 // 64-byte signature
  uint64 index = 3;                   // Index within block
  bool is_vote = 4;                   // Vote transaction flag
  SanitizedTransaction transaction = 5;
  TransactionStatusMeta transaction_status_meta = 6;
}
```

### SanitizedTransaction

```protobuf
message SanitizedTransaction {
  Message message = 1;
  bytes message_hash = 2;              // 32 bytes
  repeated bytes signatures = 3;       // 64-byte signatures
  bool is_simple_vote_transaction = 4;
}
```

### TransactionStatusMeta

```protobuf
message TransactionStatusMeta {
  bool is_status_err = 1;              // Success/failure
  uint64 fee = 2;                      // Fee in lamports
  repeated uint64 pre_balances = 3;
  repeated uint64 post_balances = 4;
  repeated InnerInstructions inner_instructions = 5;
  repeated string log_messages = 6;
  repeated TransactionTokenBalance pre_token_balances = 7;
  repeated TransactionTokenBalance post_token_balances = 8;
  repeated Reward rewards = 9;
  string error_info = 10;
}
```

***

## Account Events

### SubscribeUpdateAccountInfo

```protobuf
message SubscribeUpdateAccountInfo {
  bytes pubkey = 1;              // Account public key
  uint64 lamports = 2;           // Balance in lamports
  bytes owner = 3;               // Owner program
  bool executable = 4;           // Executable flag
  uint64 rent_epoch = 5;
  bytes data = 6;                // Account data
  uint64 write_version = 7;
  optional bytes txn_signature = 8;
  optional SlotStatus slot = 9;
}
```

***

## Slot Events

### SlotStatusEvent

```protobuf
message SlotStatusEvent {
  uint64 slot = 1;
  uint64 parent = 2;
  int32 status = 3;              // 0=processed, 1=confirmed, 2=rooted
  bytes block_hash = 4;          // 32 bytes
  uint64 block_height = 5;
}
```

***

## Supporting Types

### Message (Transaction)

```protobuf
message Message {
  uint32 version = 1;                  // 0=legacy, 1=v0
  MessageHeader header = 2;
  bytes recent_block_hash = 3;         // 32 bytes
  repeated bytes account_keys = 4;     // 32-byte keys
  repeated CompiledInstruction instructions = 5;
  repeated MessageAddressTableLookup address_table_lookups = 6;  // v0 only
  LoadedAddresses loaded_addresses = 7;                          // v0 only
  repeated bool is_writable = 8;
}
```

### CompiledInstruction

```protobuf
message CompiledInstruction {
  uint32 program_id_index = 1;
  bytes data = 2;
  repeated uint32 accounts = 3;
}
```

### TransactionTokenBalance

```protobuf
message TransactionTokenBalance {
  uint32 account_index = 1;
  string mint = 2;
  UiTokenAmount ui_token_amount = 3;
  string owner = 4;
}

message UiTokenAmount {
  double ui_amount = 1;
  uint32 decimals = 2;
  string amount = 3;
  string ui_amount_string = 4;
}
```

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.thornode.io/infrastructure/thorstreamer-grpc/api-reference/message-type.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
